email system, new, improved

Improved handling for inactive or unverified campaign domains

June 1, 2026

Email delivery is now better protected when a domain mapped in your Campaign Domain settings becomes inactive or unverified.

Previously, emails could continue attempting to send after a mapped domain became inactive. With this update, email delivery is automatically prevented in those cases, and a clear failure message is shown in Conversations.

What’s new

  • Emails are automatically stopped if the mapped Campaign Domain becomes inactive or unverified.
  • Failed email attempts display a clear error message in Conversations.
  • Improved visibility into email delivery issues caused by domain verification status changes.

Why it matters

  • Helps prevent failed or unauthorized email delivery attempts from inactive domains.
  • Makes it immediately clear why an email failed.
  • Improves troubleshooting by surfacing domain verification issues directly in Conversations.
  • Enhances email reliability and domain compliance handling.

How it works

  1. If a Campaign Domain status changes from Active to Inactive or Unverified, sending automatically stops for emails using that domain.
  2. The email activity is marked as failed.
  3. A message in Conversations explains that the email failed because the domain is not verified.
