How it works

Bounce Shield is our system that works in the background while your emails are being sent. You do not need to turn it on as it constantly monitors your campaigns.

We implemented it to help you protect your deliverability and avoid reaching your provider's send quota, which could result in a 24-hour block.

As soon as our system detects that your sending volume is about to reach the limits of your provider, we stop sending your emails for a few minutes. After a certain amount of time, sending will resume.

What does it protect me from?

In general, it helps to maintain good deliverability by keeping your sending below your provider's limit.

This way, you avoid being blocked by your provider (which would stop your sending for the entire day) and have a better chance of having and keeping a good reputation as a sender.
