Error message

If the rate limit is exceeded, the following error occurs:

554 5.7.1 Recipient address rejected: Rate limit exceeded - More information on https://go.creoline.de/kb/61521


Please note that emails that violate the maximum rate limit are not automatically added to the queue for outgoing emails. Emails that are rejected using the code 5.7.1 must be resubmitted as soon as the rate limit is exceeded again.



Measurement details

The rate limit is measured on the basis of relative time. The respective intervals relative to the transmission attempt are therefore taken into account for each transmission attempt. Please note that the daily rate limits are not automatically reset at 0:00, but are evaluated relative to the last 24 hours.
