The error 'Daily user sending quota exceeded' means that you've reached the daily limit of the number of emails that can be sent from your email account, or the campaign email has been flagged as spam by email providers, and its sending has been temporarily limited.
To resolve this error, please follow these practices:
Avoid including links in the first email of the sequence.
Add spintax to create variation across emails.
Reduce the number of emails you are sending each day. We recommend 30 campaign emails + 10 warmup emails per day per account.
These small adjustments resolve the issue automatically once the sending reputation resets, usually within 24-48 hours.
