If you use public domains like Yahoo or AOL as your email sender address when sending campaigns from the Mailigen system, your emails will get blocked and never reach subscribers’ inboxes in the TOP mail service providers like Yahoo, AOL, Gmail, Outlook and others which agree with the DMARC policy.
Take into account the DMARC policy if sending your email newsletters from:
- public domains;
- private domains without authentication.
In this blog post, you will find everything about DMARC: what it is and why it is used. But first, find out how to avoid getting blocked and how to reach subscribers’ inboxes. Here we have two recommendations!
1. Send emails from your company’s domain email address
We suggest you to change your Mailigen sender email address from Yahoo, AOL or any other public email to your company’s domain email address. In this case, emails will not get blocked or land in the spam folder. Check out here if your sender email domain is DMARC protected.
2. Authenticate your company’s domain to improve delivery
If you send emails from your company domain and have implemented the DMARC policy, we suggest you to authenticate your private domain before sending emails from the Mailigen system. This will considerably improve your email delivery results. Learn more about the DMARC implementation and your domain authentication.
But now let’s have a deeper insight into the DMARC policy!
What is DMARC and why is it used?
DMARC stands for Domain-based Message Authentication, Reporting and Conformance. It means setting up a protection mechanism for a certain domain.
The owner of a domain may set up DMARC in the Domain Name System (DNS) because of two important reasons:
- to be informed about third parties who send emails using his or her private domain (for example, mailigen.com) without authentication;
- to inform the recipient server (for example, gmail.com) about what to do with this email – block it, send it to the spam folder or to the inbox folder.
How does DMARC actually work?
Let’s look at two examples on how DMARC actually work.
1. When you use @yahoo or @aol as your sender email address when sending emails from your Mailigen account to MPS like @yahoo, @aol, @gmail or @outlook, MSP systems will check public DNS to find out whether Mailigen servers are allowed to send emails from the Yahoo or AOL domains. Unfortunately, Yahoo and AOL do not offer such permissions, so your emails will be blocked.
2. If you set up DMARC in order to reject all the emails sent from the Mailigen system without domain authentication, then emails will be blocked by @yahoo, @aol, @gmail, @outlook and other MSP which agree with the DMARC policy.
Here are some examples of blocked diagnostic codes:
Diagnostic-Code: smtp;550 5.7.1 [18.104.22.168 12] Our system has detected that this message is likely unsolicited mail. To reduce the amount of spam sent to Gmail, this message has been blocked. Please visit http://support.google.com/mail/bin/answer.py?hl=en&answer=188131 for more information.
Diagnostic-Code: smtp;521 5.2.1 : (DMARC) This message failed DMARC Evaluation and is being refused due to provided DMARC Policy
Diagnostic-Code: smtp;550 5.7.0 (SNT0-MC1-F46) Unfortunately, messages from (22.214.171.124) on behalf of (aol.com) could not be delivered due to domain owner policy restrictions.
Diagnostic-Code: smtp;554 5.7.9 Message not accepted for policy reasons. See http://postmaster.yahoo.com/errors/postmaster-28.html
How to set up DMARC?
There are various ways how to set up DMARC for your domain DNS. For example, you can set up an option to receive reports when somebody is sending emails from your domain without permission (authentication).
Mailigen has also set up this option for its domain, so that no one else is able to send email campaigns from the Mailigen domain.

Take care of your email campaign delivery
Due to the increase of email activity, MPS search for more and more new solutions to restrict spam and improve the overall email ecosystem. That’s why we don’t want you to think about the DMARC policy as an obstacle but rather than an opportunity to improve your sender’s reputation and boost your delivery rate. Send email campaigns from your company’s domain email address and authenticate it to receive exceptional email marketing results!
