Sending Limits

Hourly Limits

When you first sign up for Mailtrap and verify a domain, we limit your throughput to 100 emails an hour. This is a security measure to prevent abusing our system for spam. 

The good news is that the limit gets lifted when you submit a request and our team reviews your domain. It typically takes two business days. If you need a higher rate limit, please submit a request, and our tech support team may enable it for you. 

For now, should you exceed the limit of 100 emails per hour, we’ll send the excess emails in the next hour if there’s room for that. But this is only a temporary solution. 

In near future, our system will reject excess emails when you reach the limit. Therefore, it’s best to submit a request and talk to our experts to extend the limit. 

Connection Limits

Max number of concurrent SMTP connections per account is 10.

If you exceed this limit you'll get such error:

535 5.7.8 Too many connections per account 

Max number of concurrent SMTP connections per IP is 10.

If those limits are not enough, please let us know by contacting our Support Team.
