High bounce rate for emails

According to our Terms of service, forms with high email bounce rates will be limited for abuse. In order to bring more clarity on this matter, here you can find which are the rules we are following when limiting forms/users for high email bounce rates.


How can users reach a high bounce rate?

Our threshold of allowed bounced emails is 5% of the sent emails.

If there are more than 90 emails sent in the last one hour, we are allowing a bounce rate lower than 5%. This means that we are allowing you to send 90 ignored emails, but starting with email number 91, if the percentage of bounced emails is >=5%, then your account will be blocked.


How are we treating each particular case?

If you are a free user and if you reach the maximum allowed threshold of 5% bounced emails, your account will be blocked. In this case, you need to get in contact with Customer Care.

If you are a premium user on days one and two of your lifetime and you reach 5% bounced emails, then your account will be blocked. You can sort this out by getting in contact with Customer Care.

If you are a premium user and your account is older than 3 days, then all email notifications from any form will be blocked. Additionally, you are going to receive an email with information about the form that caused the high bounce rate.
