Are you blocklisted?

Enter your IP address or domain to check if it’s on the Return Path Blocklist.

Why am I blocklisted?

When IPs are blocklisted, they usually engage in high-risk sending behavior, such as:

  • Sending to email addresses that never subscribed to receive communications
  • Sending email campaigns from botnets
  • Sending messages containing suspicious attachments
  • Email authentication failures

Often these high-risk sending behaviors include security issues such as bad data partners or viruses sending mail through your network.

If you find yourself on the Return Path Blocklist, it’s a sign that you’re likely experiencing underlying issues with your email program. Being able to proactively monitor listings and identify the cause is essential to resolving these issues.
