Previously, deliverability consisted mainly in applying the basic rules of ing relating to content (text, images, html code ) Today, the main factors also taken into account are the quality of the platform and the mailing list.

5 Deliverability: Everything you need to know in 34 tips - Technical Platform 1. Authenticate your s By authenticating your domain, your recipients will not see the sent via text (see image below) and your domain name reputation will be improved. SPF : This oldest authentication method adds the IP addresses allowed to send via your domain name in your DNS record. DKIM : Also based on the DNS record, this authentication solution is used to sign s with a public or private key system. DMARC : This new technology allows the sender to check whether s have been properly authenticated by the ISP or webmail. If you already have a Mailjet account, log onto our website and use our Assistant to configure your SPF and DKIM. If not, you can sign up here. 5/ Mailjet SAS - All Rights Reserved -

6 Deliverability: Everything you need to know in 34 tips - Technical Platform 2. Use a public Whois The whois lists the contact information related to a domain name. They include information on the owner, the technical contact and the host of your domain. Disclosed information includes: the full name, address, postal address and telephone number of each reference. Some providers allow the option of hiding this information, or making the WHOIS Private. This practice is used by spammers and should be avoided at all costs. Read more about it on the guide: Deliverability of your s This is one of the first things verified by our team in case of problems. The need for a public WHOIS is fairly recent: previously, it only applied to large senders. 6/ Mailjet SAS - All Rights Reserved -

7 Deliverability: Everything you need to know in 34 tips - Technical Platform 3. Pay attention to forward and reverse DNS lookup To verify your identity, ISPs and webmail frequently use DNS (Domain Name System). That is why it is important to properly configure these settings in the control panel of your web host account (if your host allows it). Reverse DNS lookup : verification of a domain name associated with an IP address; Forward DNS lookup : verification of an IP address associated with a domain name. Our technical team can help you with these complicated configurations. Don t hesitate to contact us if you need assistance! 7/ Mailjet SAS - All Rights Reserved -

8 Deliverability: Everything you need to know in 34 tips - Technical Platform 4. Adopt a dedicated IP address? The IP addresses used to identify the origin of s routed through servers acquire a reputation (positive or negative), which is based on the quality of messages and interactions generated. Having a dedicated IP means that you don t have to share the reputation of your IP with other users on your mailing platform. However, to acquire a good IP reputation takes time and regular sending volumes. It is therefore important to conduct a warm up period and send at least a few thousand s per day. Read more about it on the blog: how to monitor the reputation of your IP address Mailjet s IP addresses are closely monitored by our deliverability team, guaranteeing an excellent reputation. You can benefit from a dedicated IP address which are available on our Silver package. 8/ Mailjet SAS - All Rights Reserved -

9 Deliverability: Everything you need to know in 34 tips - Technical Platform 5. Don t forget to warm up your IP address (in case of a dedicated IP address) When you begin sending s with a new IP address, it has no reputation and is not immediately trusted by ISPs & webmail providers. In order to build up this trust, you must warm up your IP address by sending a consistent number of high quality s every day for 3 to 4 weeks. By default, the warm up isn t necessary because shared IP addresses on Mailjet already have a stable, trusting relationship with ISPs. If you opt for a dedicated IP, our teams will support you throughout the warm up period. In any case, automatic limits are applied to new accounts to avoid any incidents. 9/ Mailjet SAS - All Rights Reserved -

10 Deliverability: Everything you need to know in 34 tips - Technical Platform 6. Should you separate transactional and marketing s? It is important to use different addresses for marketing and transactional s. By separating your various types of , it will also separate potential delivery issues when they arise. Recently, intelligent inboxes, at Gmail and Outlook.com for example, have begun to automatically sort s by category: Promotions, Notifications, and Social. In order to avoid your confirmation s arriving in the Promotions category, it is important to separate your transactional and marketing messages. Read more about it on the blog: Power Up Your Transactional s With Mailjet, it s possible to separate different types of s via subaccounts and manage the priority of outgoing s. Do not hesitate to contact us to discuss your needs. 10/ Mailjet SAS - All Rights Reserved -

11 Deliverability: Everything you need to know in 34 tips - Technical Platform 7. Use a domain name linked to an existing website Verifying sender information is an essential element in the fight against spam. Spammers don t create websites for their sender domain, (i.e., free-viagra.biz). If your domain directs readers to an empty website page, how will ISPs react? They will automatically be suspicious of you. You should use a sender address corresponding to a professional domain name that contains, at the minimum, a webpage describing your business, a privacy policy page and full contact information. 11/ Mailjet SAS - All Rights Reserved -

12 Deliverability: Everything you need to know in 34 tips - Technical Platform 8. Take advantage of throttling This technique consists of adjusting the sending speed of s/ campaigns in order to respect the rules established by the main ISPs. The configuration of several different parameters will optimize your deliverability: - The number of s sent per minute or hour - The number of connections per minute or hour - The number s sent per connection Mailjet adjusts the sending speed and the number of simultaneous connections in real time in order to optimize the deliverability of your s. You will also benefit from the experience of our deliverability team. 12/ Mailjet SAS - All Rights Reserved -

13 Deliverability: Everything you need to know in 34 tips - Technical Platform 9. Configure abuse@ and postmaster@ addresses These are addresses to receive consumer complaints (abuse@) and information on potential technical problems (postmaster@). If these addresses are not configured for your domain name, they can return an error to ISPs, indicating that you don t pay attention to these messages. This is not good! By default, Maljet manages these returns for the most popular ISPs that meet industry standards. But beware: if our abuse@mailjet.com address is solicited, our deliverability team will be alerted and your practices may be investigated or questions. Finally, note that these addresses are required for certain whitelisting procedures. 13/ Mailjet SAS - All Rights Reserved -

14 Deliverability: Everything you need to know in 34 tips - Technical Platform 10. Consider Return Path certification Return Path offers certification for your IP address (a white list) that allows you to speed up the delivery of your s to inboxes (for a limited list of ISPs and webmails). Certification can also permit images to be displayed by default: your recipients will not have to click on the display images message. The benefits are many, but this certification is only for large senders and can quickly become expensive. Our privileged partnership with Return Path allows for rapid contact and collaboration. Contact us if you are interested. 14/ Mailjet SAS - All Rights Reserved -

15 Deliverability: Everything you need to know in 34 tips - Technical Platform 11. Consider using seedlists By adding a sample of addresses to your contact list, it is possible to verify that your s are delivered. Unless you go and check each of your contacts inboxes, it is difficult to know if your arrived at its destination. This technique involves creating a batch of witness addresses to check if your was properly received. Our interface does not offer access to Mailjet seedlists or their results. But in some cases, our deliverability team may propose to carry out these tests for you on a dedicated IP, during the warm up phase. 15/ Mailjet SAS - All Rights Reserved -

16 Deliverability: Everything you need to know in 34 tips - Technical Platform 12. Monitor black lists There are many blacklists used by ISPs and webmails to filter incoming messages. Often referred to as RBL or DNSBL, these lists are mostly governed by independent anti-spam services. They usually block certain IP addresses or entire networks. In addition to being widely used by ISPs, the most serious blacklists are part of a consortium that actively communicates and shares information. Many services offer to verify whether your IP address and domain name are present on a blacklist. For example: Mxtoolbox.com or Blacklistalert.org. Read more about it on the blog: 5 Ways To Avoid Landing On An ISP Blacklist. Our deliverability team carries out preventative monitoring of different blacklists. We also have many contacts with ISPs and blacklists services, which facilitates the unblocking process, when it is necessary and justified. 16/ Mailjet SAS - All Rights Reserved -

17 Deliverability: Everything you need to know in 34 tips DATA QUALITY Deliverability largely depends on engaging recipients. Beyond content, data quality is of the utmost importance. Monitor spam complaints and use feedback loops Adopt an obvious and immediate unsubscribe process Manage your errors (bounces) Do not buy or exchange addresses Use a double opt-in procedure Send campaigns regularly Delete inactive addresses 17/ Mailjet SAS - All Rights Reserved -

18 Deliverability: Everything you need to know in 34 tips - Data Quality 13. Monitor spam complaints and use feedback loops Certain ISPs and webmails allow you to receive an alert when your is flagged as spam, also known as a feedback loop (FBL). It is important to record these complaints and remove associated contacts from your lists. The mechanism involves indicating to ISPs that you want to be notified of spam messages reported against you in order to process them. This approach is not possible for all ISPs and is usually done via a form directly found on their websites. Read more about it on the blog: SPAM: the gift that no one wants Mailjet automatically generates feedback loops for larger ISPs. Reports of spam are displayed in your account and available via our APIs. The relevant contacts are automatically blocked. 18/ Mailjet SAS - All Rights Reserved -

19 Deliverability: Everything you need to know in 34 tips - Data Quality 14. Offer a clear and instantaneous unsubscribe option An unsubscribe link is essential to avoid being classified as spam. The link to the unsubscribe page must be functional, instantaneous and easy to find in the . Do not ask users to confirm their desire to unsubscribe and reassure them that you will no longer contact them. Otherwise, they will confirm this themselves by flagging you as spam and blocking your sender address. If you use our online interface, the unsubscribe link and page are managed automatically. Through SMTP relay, you must manage this yourself, or add the tag [[UNSUB_LINK_EN]]. 19/ Mailjet SAS - All Rights Reserved -

20 Deliverability: Everything you need to know in 34 tips - Data Quality 15. Manage your errors (bounces) It is very important to address the s that result in errors by deleting the offending addresses from your lists. Indeed, ISPs penalize high error rates because they often reflect poor practices (old lists, no double opt-in, etc.). Permanently deleting addresses that bounce back with errors allows you to maintain a clean database, free of inactive or nonexistent contacts. Note that temporary errors, Soft Bounces (full mail box, automatic away message...), should not be cleaned immediately. Only Hard Bounces, or permanent errors, should be addressed right away. Consult our documentation regarding status. Mailjet s deliverability optimization system processes these errors. When they are temporary, new attempts to send are made automatically. Only after a certain number of unsuccessful attempts will the result in an error status. It is then automatically blocked for 90 days. 20/ Mailjet SAS - All Rights Reserved -

21 Deliverability: Everything you need to know in 34 tips - Data Quality 16. Do not buy or exchange contact lists Lists of addresses that circulate on the Internet have usually been copied many, many times. They are of very poor quality and are riddled with spam traps (fake addresses). Only use contact lists that you control. Recipients must explicitly agree to be contacted (opt-in). Avoid the so-called tips from friends, colleagues, and partners. You should especially be wary of sites specializing in the sale or rental of databases. In addition to being discouraged by ISPs, this practice often results in lost money, along with the risk of blacklisting and this should be avoided at all costs. To read: Mailjet s anti-spam policy Buying or exchanging addresses is against our anti-spam policy. Our system and deliverability team have the ability to detect it. If you participate in this practice, you risk having your accound closed, without notice and without a refund. 21/ Mailjet SAS - All Rights Reserved -

22 Deliverability: Everything you need to know in 34 tips - Data Quality 17. Use a double opt-in procedure Double opt-in consists in validating the address via , in order to verify that it does in fact exist and is in working order. This is a very effective way to increase the quality of addresses gathered. In addition to guaranteeing the existence of the address, you will also be able to verify that your contact is indeed its owner. This process consists of adding a confirmation link in the welcome and to validate the address only once the link is clicked. Check out some of our plugins for your website, where you can add a sign up widget. If the double opt-in is not required from a legal standpoint, it is nevertheless required by ISPs. At the very least, quickly identify errors generated by subscription confirmation s and use them to update your contact lists. 22/ Mailjet SAS - All Rights Reserved -

23 Deliverability: Everything you need to know in 34 tips - Data Quality 18. Send campaigns regularly Never leave your addresses alone for months at a time! Your contacts have memories almost as short as the lifespan of their addresses (about 6 months). Regularly send s (example: a newsletter) to remind them of you. This approach is also beneficial for your brand. Without regular mailings, some customers will forget they subscribed. Their reaction will then be to report you as spam! Solicit your contacts at least once a month. If your list has not been used in the last 6 months, contact our support team before any sending. Otherwise, errors will cause a blockage or worse, blacklisting. 23/ Mailjet SAS - All Rights Reserved -

24 Deliverability: Everything you need to know in 34 tips - Data Quality 19. Unsubscribe inactive addresses When a recipient does not respond to your s for several months, this can mean several things. Either he does not use the address in question anymore, or perhaps he is no longer interested in your offer. In either case, this is detrimental to your reputation. In the worst-case scenario, these inactive addresses can become spam traps. The greater the number of inactive contacts, the more your reputation rate suffers, impacting your deliverability. It is thus necessary to delete these addresses or create a special reengagement program. Read more about it on the blog: How to avoid the pitfalls of inactive contacts? Unsubscribe all inactive addresses (no clicks or opens) over the past six months. 24/ Mailjet SAS - All Rights Reserved -

25 Deliverability: Everything you need to know in 34 tips CONTENT Certain tips described below allow you to more easily bypass antispam filters. Others serve to increase the quality of interactions generated by your s, thus improving your reputation and deliverability. Create multipart s (HTML + Text version) Avoid image-only s Delete words frequently used by spammers Make the sender clearly identifiable Observe good HTML practices View your rendering Test your content in different spam filters Use pre-headers Do not use links that contain an IP address 25/ Mailjet SAS - All Rights Reserved -

26 Deliverability: Everything you need to know in 34 tips - Content 20. Create multipart s (HTML + text version) Make sure your s are composed of two parts, one in HTML and one in text format. The text version of your s remains indispensable. Certain clients do not yet display HTML on mobile devices and anti-spam filters compare the content of text and HTML versions to ensure that they are similar. Our campaign design tool automatically generates a text version for you. If you are sending by other means (API, SMTP...), do not forget to create a text version and be sure to check the content generated. 26/ Mailjet SAS - All Rights Reserved -

27 Deliverability: Everything you need to know in 34 tips - Content 21. Avoid image-only s Spammers have a habit of hiding the text of their s in images to avoid spam filters. As a result, these filters have learned to be wary of images. Images should only be used as decoration and should never replace text. Read more about it on the blog: Avoid image-only s Images should not exceed 25% of the surface of your s. In addition, they should not contain any text. 27/ Mailjet SAS - All Rights Reserved -

28 Deliverability: Everything you need to know in 34 tips - Content 22. Delete words frequently used by spammers Talking about little blue pills or a certain famous brand of Swiss watches in your s is not a great idea, as you undoubtedly know by now. But there are many other words that suggest spam/phishing, and their use should be limited. Examples of words that are less obvious than Viagra or Rolex but should be avoided in excess: Free, Credit, Pharmacy, Sale, Promotion, Click here, Urgent, etc. Check out our post on: Words That Will Trip The Spam Alarm Exercise caution! Patiently reread your content and find clever turns of phrase to spark the interest and curiosity of your recipients, without using problematic words. 28/ Mailjet SAS - All Rights Reserved -

29 Deliverability: Everything you need to know in 34 tips - Content 23. Make sure the sender is clearly identifiable It is crucial that your subscribers recognize your s at first glance. Otherwise, the chance of your being marked as spam is higher. The easiest way to identify yourself is to use the name of your brand or site in your sender name. We even recommend that you always mention your brand /domain name in the subject line. This practice is welcomed by recipients and antispam filters alike (because it shows them that you are not trying to hide anything). 29/ Mailjet SAS - All Rights Reserved -

30 Deliverability: Everything you need to know in 34 tips - Content 24. Respect good HTML practices It is sometimes time-consuming and daunting to code your HTML s (using tables, online CSS...). However, spam filters attach great importance to the quality of your code. Do not forget to close your tags, write the HTML code in lowercase, add alternative attributes of your images... In short, follow the rules! If you are not an expert in HTML, use our WYSIWYG editor: the code will be self-generated and automatically optimized! 30/ Mailjet SAS - All Rights Reserved -

31 Deliverability: Everything you need to know in 34 tips - Content 25. Visualize your rendering To ensure a maximum level of interactions, it is necessary that your designs are perfect! As each client has its bugs and display tips, it is essential to test reports on several of them. Gmail does not support <style> tags... </ style>, Outlook does not handle background images and CSS3 is still supported by very few... There are many peculiarities. On the client side, test on the most popular providers: Apple Mail, Thunderbird and Outlook. On the webmail side, do the same: Outlook.com, Gmail and Yahoo!Mail are a good starting point. Also, don t forget mobile devices: iphone, Android, etc. Don t rely on fancy design or anything too complicated. Emphasize content and follow the standards, as old as they may be. When in doubt, use one of the many testing tools available on the market (Litmus, Return Path...). 31/ Mailjet SAS - All Rights Reserved -

32 Deliverability: Everything you need to know in 34 tips - Content 26. Test your content in different anti-spam filters Each spam filter reacts differently to the content of your s. This is why it is important to be careful and test each of them. SpamAssassin is the best known and most widely used spam filter and there are dozens of others out there. For example: VadeRetro, Cloudmark, Barracuda, Postini... not to mention the various filters of clients (Outlook, Thunderbird...) and webmails. Tools like Litmus and Return Path let you test your s in different spam filters. In the Mailjet interface, a SpamAssassin score is displayed in reports. Feel free to send a campaign to test addresses to verify it. 32/ Mailjet SAS - All Rights Reserved -

33 Deliverability: Everything you need to know in 34 tips - Content 27. Use pre-headers Some interfaces display the first few lines of the message just below the object. This is a space to be utilized and used to your advantage. Too often, the user see the familiar useless pre-headers: See the online version, click here to see.. or if you do not see... What a waste! Even the recipients who do not open the read these lines. Read more about it on the blog: tips on optimizing your newsletters for mobile. Take the opportunity to use this space to include a tagline or a complementary introduction to your topic. Our online tools allow you to do this in 2 clicks. 33/ Mailjet SAS - All Rights Reserved -

34 Deliverability: Everything you need to know in 34 tips - Content 28. Links: Avoid IP addresses, link shorteners... Carefully avoid the links generated by advertising or URL shorteners. Also, do not use IP addresses as links! These mechanisms are often used by spammers to conceal landing pages. Identification is one of the keys to deliverability; it is essential that the links used in your s reflect the identity of the landing page. We automatically offer tracking links to detect openings and clicks on the r.mailjet.com domain. But also know that it is possible to modify these links for the benefit of addresses corresponding to your domain name. 34/ Mailjet SAS - All Rights Reserved -

35 Deliverability: Everything you need to know in 34 tips OTHER BEST PRACTICES Whether obvious or not, these little tips are good to remember and could make all the difference for your deliverability. Avoid noreply addresses Segment to increase reactivity Obey the law Be consistent with the promises made at the time of subscription Provide a link to the privacy policy in your s and on your website Invite your subscribers to add you to their address book Here s a quick crash course on how to Segment and Personalise using Mailjet: 35/ Mailjet SAS - All Rights Reserved -

36 Deliverability: Everything you need to know in 34 tips - Other Best Practices 29. Avoid noreply addresses A sender address should always be able to receive s. Take care of your contacts and do not cut off the conversation with a noreply@yourdomain.com address. You would be much better off with yesreply@yourdomain.com! In case of questions, comments, or problems related to an , the reply button is naturally very often used because it is so accessible. Isn t it illogical to invest in social media and then cut the conversation via short? In terms of customer relations, noreply@ makes no sense. Why not use an address linked to your customer service or your Community Manager? This will humanize the communication. 36/ Mailjet SAS - All Rights Reserved -

37 Deliverability: Everything you need to know in 34 tips - Other Best Practices 30. Segment in order to increase reactivity All of your recipients have different needs and expectations. Classify your contacts by their affinities, how they use your services, or better, offer personalized subscription options (subject, frequency ). Consider using a CRM and/or offer subscriptions tailored to your contacts. See how you can Segment your data with Mailjet. 37/ Mailjet SAS - All Rights Reserved -

38 Deliverability: Everything you need to know in 34 tips - Other Best Practices 31. Obey the law Legislation on respect of privacy is different in almost every country. It is important to educate yourself. You also have responsibilities to protect the privacy of your users. Storage of their personal information should be secure and sometimes even authorized by the user himself. Check the validity of your registration process, conditions of use and your legal disclaimer. If you respect your subscribers, chances are that you are also obeying the law. Mailjet requires opt-in and opt-out procedures. Privacy and data security is a priority for our teams. With servers in Europe, Mailjet users are not affected by PRISM. 38/ Mailjet SAS - All Rights Reserved -

39 Deliverability: Everything you need to know in 34 tips - Other Best Practices 32. Be consistent with the promised you made at the time of subscription Obtaining the address of your contact does not give you the right to do whatever you want. Do not excessively contact your users; you should respect their habits and the reason why they signed up in the first place, or else they may use the spam button against you. If you promised one newsletter per month, there is no question of changing the rules along the way warn your users and give them the opportunity to change their preferences. If the rules change, ask for permission again or offer an alternative to avoid irritating your contact. 39/ Mailjet SAS - All Rights Reserved -

40 Deliverability: Everything you need to know in 34 tips - Other Best Practices 33. Provide a link to your privacy policy This is a crucial factor in gaining your subscribers trust, but it is also important for ISPs and webmails, in case of an unblocking request. Be as reassuring as possible about your practices and your respect for your subscribers. Create a privacy policy web page on the subject that will also contains your contact information. Providing a phone number is often a plus. In the header or footer of your , remind your contacts how you got their address and why you are contacting them. 40/ Mailjet SAS - All Rights Reserved -

41 Deliverability: Everything you need to know in 34 tips - Other Best Practices 34. Invite your subscribers to add you to their address books This will allow you to easily send s to the recipient s inbox. This is a positive for anti-spam filters. In your communications, it is rare to find a message from a friend, parent, or colleague in your unwanted mail. This is simply because one or several exchanges have already taken place and each party has the other in his list of contacts. Use your welcome s and/or your subscription confirmation page to encourage your subscribers to add you to their address books. 41/ Mailjet SAS - All Rights Reserved -
