FAQs
What is the difference between a suppression list and an exclusion list?
In MailerSend, a suppressions list refers to a list of emails that have hard bounced, soft bounced, or resulted in a spam complaint or unsubscribe. These are emails that could negatively impact your sender reputation and email delivery if you continue to send to them.
How do email suppression lists improve deliverability?
By adding bounced emails, unsubscribes and spam complaints to your email suppressions list, you show ISPs (Internet Service Providers) that you actively maintain your recipient list and carry out healthy email sending practices. As a result, sending reputation is maintained or improved which allows your emails to reach more inboxes and avoid spam folders. You can learn more about how suppressions improve deliverability in our article.
What is a suppression list in GDPR?
A suppression list can help you adhere to GDPR guidelines by excluding recipients who have opted out or made a spam complaint from receiving future emails.
How do I set up and manage an email suppression list with MailerSend?
MailerSend automatically sets up and adds hard bounces, unsubscribes, and spam complaints to your suppressions list, while recurring soft bounces are added to the on-hold list for 72 hours. The suppressions list page allows you to easily view and manage these email addresses, as well as manually add email addresses or emails that follow a specific word pattern.
