In this article you will discover how to increase your email deliverability. Deliverability is the ability of your emails to reach your recipients' inboxes. We've put together some tips that will help your emails reach your recipient's inbox.
Warm up your email
When your email address is not used to do mass mailing, it is important to warm it up. Indeed, one of the key factors of a good deliverability is the reputation that your email address has with your provider. If you have never done mass mailing, then your email address will not have the required reputation and your emails will end up as SPAM or even worse you will no longer be able to send any email.
Increase the number of emails sent gradually
To warm up your email address, we recommend you to follow the following instructions:
Week 1: Send 10 emails per day per email address
Week 2: Send 25 emails per day per email address
Week 3: Send 50 emails per day per email address
Week 4: Send 80 emails per day per email address
In the same way, after one month of practice on our software, you will have to continue to gradually increase the number of emails sent per day before reaching your maximum quotas which are listed in the following article: Email sending quotas.
Send emails to contacts who reply
Increasing the email volume gradually is a first step in warming up your email address. However, the reply rate that you will get has major impact on the deliverability. In order to increase this reply rate, we recommend you to contact people whose email address is verified and who are more likely to respond to you in the beginning. This will allow you to get a high response rate on small volumes of emails sent and thus increase your deliverability.
Reputation & Authentification
The good reputation of your domain and your email server will prevent you from falling into the "spam box" of your prospects. It will also prevent the receiving server from simply blocking your message. To ensure a good reputation, here are a few tips:
- Make sure you use a trusted email client and server: Gsuite and Gmail, Exchange and Outlook as well as OVH are very good solutions.
- Get to know your prospects. If your e-mails are deleted unread or marked as spam, your reputation will be affected. On the contrary, if your prospects open, reply or forward your e-mails, your reputation will be enhanced and your ROI (openings, clicks, replies) will increase.
- Give your prospects the choice to unsubscribe from your communications: A prospect who unsubscribes will have a minor impact on your business, but if he doesn't find the button he may well declare your email as spam and damage your reputation in the long run.

- Limit the number of simultaneous prospects within the same company, and avoid sending them emails in short time slots.
- Clean your email lists regularly. Before adding contacts to sequence, do not hesitate to take a few minutes to have your e-mails checked to reduce your risk of bounces (see What is a bounce? ).
- Send quality content. Do not use only capital letters in your objects (e.g. CONTACT). Avoid short URLs (e.g. bit.ly). Do not use "spam words" (e.g. "free", "promotion", "urgent", ... or "casino" or "100%").
- Focus on the text in your emails : the content of your emails should be mostly text. If your emails are short and contain little text, make sure that your signature (image, link, etc.) is not too loaded with images. Also, never send an image alone or with very little text.
- Use a professional and personal email. Using a free (e.g. gmail.com, hotmail.com, laposte.net, etc.) or generic (e.g. email@example.com, firstname.lastname@example.org, etc.) email address is both discouraged and not in compliance with the GPDR.
SPF, DKIM et DMARC
Although these three notions may seem frightening at first glance, it is important for you to understand them. Configuring these three indicators will allow you to increase your deliverability.
SPF (Sender Policy Framework) - Policy and Issuance Rules
The main goal of SPF is to reduce the amount of SPAM that your client will receive in his mailbox. It is a standard verification of your domain name that allows you to know if a message sent comes from a valid or invalid sending email address.
The principle is to link the IP address of a mail server to its domain name in order to reduce identity theft attempts by publishing a so-called SPF record in the DNS.

DKIM - DomainKeys Identified Mail
The DKIM can be compared to a signature on your email that will allow your client's server to verify that you are the sender of the email. DKIM does not prevent you from being sent in SPAM, but allows you to be more legitimate with the servers.

DMARC - Domain based Message Authentication, Reporting and Conformance
DMARC is a synthesis between the SPF and the DKIM. It has 2 functions:
1. It indicates you what should be done with your message if authentication fails (let it pass, delete it, classify it as SPAM)
2. It allows you to be notified when authentication fails

Test my email address
Test one or several email addresses
If you want to test your e-mails before launching your sequences, Mail-Tester will enlighten you on the best way to build your e-mail to avoid the spam box. It also sheds light on the authentication and reputation of your domain. Send your e-mail to the email address provided by the tool and you will know the score of your email address.
Test your domain and email server
If you want to test the domain name associated with your email address, you can go to mxtoolbox.com. You just need to fill in the domain name of your email address as it is shown in the example below and click on MX Lookup.
Then click on Find Problems
You will then be able to see the test results obtained with MX Toolbox. For some of the results, you can click on More Info for more information. By clicking on More Info you will be guided through the resolution of the problems you have encountered: presence in a blacklist, ...
In addition to the MX Toolbox, you will be able to check your IP and your domain by going to the following two websites: SpamHaus and Sender Score.
Keep an eye on your openings, clicks, responses and bounce rate
The weaker your tracking metrics are, the more you deteriorate your deliverability! You need to think about implementing a strategy to improve your rates, especially of openings and clicks. Unopened, unread then deleted, or spam-labeled emails can damage your reputation. On the contrary, if your prospects open, reply or forward your emails, your reputation will increase significantly as well as your deliverability and therefore your ROI (openings, clicks, replies).
