DMARC and Blocklist monitoring sunset

On May 21, 2026, the DMARC and Blocklist monitoring features will be sunsetted. Here’s what you need to know.

What will happen to my account on May 21, 2026?

If you currently use the DMARC and/or Blocklist monitoring feature, whether free or paid, from May 21, the tools will be discontinued, and therefore, you will no longer receive reports. If you have a paid subscription, it will be cancelled at the end of your May billing period, and you will no longer be charged.

Will I still be able to access my data after the tools are discontinued?

You will be able to access your reports according to your plan’s data retention period, even after the tools have been discontinued. This means that Free plan subscriptions will be able to access data up until 7 days after the last report was received, and Basic and Premium, up until 30 days.

Do I need to do anything?

No, you don’t need to do anything. Your subscription will be cancelled automatically when the DMARC and Blocklist monitoring features are disabled. 

Do you have another tool I can use to monitor DMARC and Blocklisting?

If you have a paid MailerCheck subscription, then you might find value in switching to MailerSend. MailerSend is a transactional messaging solution that offers email and SMS APIs, SMTP relay, inbound routing, and deliverability tools such as email verification, DMARC reporting and Blocklist monitoring.

With a MailerSend Professional plan, you’ll get:

  • 10 DMARC reporting domains 

  • 256 blocklist monitors

  • 30 days of data retention

  • Priority email support and live chat support

Professional plans start at $110/month or $88/month when choosing an annual subscription. 

Why did I receive an email about MailerCheck’s DMARC and Blocklist monitoring sunset?

You received an email about this change because your email address is linked to an account that actively uses, or has previously used, the DMARC and Blocklist monitoring tools. If you no longer wish to use your MailerCheck account, no action is necessary. 

Alternatively, if you wish to delete your account:

1. Log in and navigate to Account settings from the left-hand menu.

2. Scroll down to the Danger zone and click Delete Account.

Once you confirm that you would like your account to be deleted, it will be scheduled for deletion in 30 days.
