Hello, TrulyInbox users.

If you see the error below, it means Zoho Mail has blocked your outgoing email because it detected something that doesn't comply with their policies.

  • Common Reasons for Blocked Emails

  1. High Volume: Sending too many emails in a short period. Make sure you're not running any other campaigns other than email warmups.

  2. Blacklisted IP/Domain: Your IP or domain has been flagged.

  3. Policy Violations: Not following Zoho’s email usage rules.

  • How to Fix It

  1. Review Zoho's Usage Policy: Understand their rules here.

  2. Manage Sending Rate:

    • Spread out your emails over time. If you are running any email camping along with the email warmup, balance out the sending limit for both purposes.

  3. Contact Zoho Support:

    • If you think the block is a mistake, contact Zoho Support with details. Here is the email [email protected]

By understanding and following these steps, you can avoid having Zoho block your emails. For further assistance, contact Zoho Support.


Happy emailing
