How to send DMARC-compliant mail?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that lets you specify deliverability policies and receive reports on messages that fail authentication. Go to the DMARC resource page to learn more about email authentication. It helps you protect the domain from spoofing and allows you to set up deliverability policies.

GetResponse sends messages in compliance with all DMARC policies, ensuring that SPF and DKIM authentication are aligned appropriately with your domain. This “Custom DKIM Authentication” feature is available on all payment plans.

What issues can I have when sending through a free domain email address? 

The lack of control over the DMARC policy means that even messages from legitimate marketers can fail authentication and not be delivered to the inbox. 

Sometimes, free domain emails automatically reject messages based on a failed DMARC authentication. It can negatively affect your deliverability. 

What happens when I use a free domain email address?

Free domains, such as Gmail, can have issues with DMARC authentication because you’re not able to control their DMARC policy. To assure that you’re able to send from free domains, we change your email address to one that allows DMARC authentication to succeed. 

If you’re using a free email domain, we’ll add ‘via’ or ‘on behalf of’. The emails are sent from our domain that passes the DMARC validation on behalf of your email sending domain. This ensures your recipients get your email and their replies go straight to your sender email.

How can I improve my deliverability with a custom domain?

There are several things you can do to improve your deliverability with a custom domain.

  • Use a custom domain email address to build your own reputation as a sender that isn’t influenced by other people using the same free domain. 
  • Use a custom domain email address to make your message branding is more credible. This will you make you easily recognizable as the sender by the ISPs (Inbox Service Providers) and by your readers. 
  • Use DKIM authentication to sign your custom domain. DKIM lets you authenticate your email address and hide any references to GetResponse in the messages you send. 
  • Set up a custom DMARC policy. It protects your email address from phishing and spoofing. DMARC prevents others from sending messages imitating your email domain for purposes of compromising user accounts, enabling theft of passwords, bank accounts, credit cards, and more. 
  • When using DMARC, you can start with the policy set to “none” and then build up to more strict policies as you review your DMARC reports.
