  • Updated

Use this article to suppress recipient domains so Act-On automatically blocks sends to addresses at those domains.

Quick Reference (Advanced Users) - Click to Expand
  • Open Lists > Other Lists > Bounces & Opt-Outs > E-mail Suppression Domains.
  • Enter one domain per line (example.com).
  • Use sparingly and review periodically.
Specify domains to automatically be suppressed from all message sends on your account. Typical use cases for this include:
  • Competitors.
  • Subsidiaries or affiliated companies that should not receive your marketing messages.
  • Personal email aliases (if your organization engages strictly with business-to-business email addresses only).

To opt-out, suppress, or blocklist domains to ensure they do not receive any emails from your Act-On account:

  1. Navigate to Lists > Other Lists > Bounces & Opt-Outs.
  2. Select E-mail Suppression Domains.
  3. Enter the domains that you would like to suppress from all future mailings.
    • Make sure to hit Enter to add a new line between each entry.
    • Enter domains like example.com and test.org
  4. Save your changes.
