Is there a way we can prevent the blacklisting

Is there a way we can prevent the blacklisting.  It seems to be happening like once every two weeks.  

Thanks

Sorry for the inconvenience.

To prevent bouncing related issues, please see this guide: How to Prevent Email Bouncing Related Issues.

We highly recommend users to set up SMTP sender on their form to have more control over the emails. Here's a guide on How to Setup SMTP for a Form.

If issue still persist, please try to contact your email provider and ask them to whitelist JotForm email address. You can find JotForm Email addresses in this guide: Whitelisting JotMails IP Addresses.
