What to do when the newsletters get blacklisted after sending them out from SuperOffice Mailing?

Updated on 26 Nov 2021

I use SuperOffice Mailings to send communication to the customers. Many of the mailings are blacklisted and reported as spam. What can I do about it?

There are many possible causes of your messages being blacklisted. Please read some of them below:

  1. The recipient list that you use has a poor quality. We suggest using subscription management to make sure that your sent messages a relevant to your recipients.
  2. If you are using the SuperOffice CRM Online platform please read this FAQ which explains how to avoid being marked as Spam.
  3. If you use SuperOffice Onsite it could be that links created in the newsletters have the format referring to customer.exe. The .exe referral is seen as the threat by spam filters. Please read this article for more information.
  4. It could be that you had some temporary issues, but after you resolved them your domain or IP address already lost a good reputation.
    To check if your domain is blacklisted you can use a free web service like MXToolbox.
