Block list management is intuitive—always just a click away.

How it works

  1. Find a recipient in your dashboard by any search method—email, name, or list filter.
  2. Block them instantly from the recipient view, or add any address/email manually to your global block list.
  3. Relax. No more emails will go out to those addresses, across all senders and projects you manage!

Frequently asked

  • Can I unblock a user if needed?
    Absolutely. You can remove any recipient or domain from your block list in seconds—changes take effect instantly.
  • Does this work for domains too?
    Yes! You can block a single address or an entire domain if needed. Useful for stopping certain vendors or blocking test traffic at scale.
  • Do I need to change my integration code?
    Nope—the block takes effect at the dashboard and API level. You don't need to update your application logic.
