Introduction

You may see this response when connecting or sending through JetEmail SMTP: 421 4.7.1 Rate limit exceeded. Try again later. It means your sending has been temporarily throttled because you’ve exceeded the allowed rate for your account.

​
Who is affected?

This applies only to free accounts. Paid plans are not subject to this same rate limit.

​
What to do

  1. Wait and retry — You cannot send more mail until the current limit window passes. After that, SMTP will accept traffic again.
  2. Limits are not public — We do not publish the exact thresholds or time windows. If you hit this error, reduce your send rate or pause until you can connect successfully again.
  3. Upgrade — If you need higher or predictable throughput, consider upgrading from a free account.
