Hi Ronny! I'm glad to see the product team has already lifted the hold on your campaigns.

If you see the same error in the future, please note that the hold is placed as part of routine monitoring to ensure compliance with Federal Regulations regarding spam, further outlined in the CAN-SPAM Act.

This hold can happen based on the percentage of email addresses in your client list that didn't receive your message due to it being rejected by the recipient's email server. In that case, you would just have to erase the contacts whose email addresses bounced (or fix their email addresses if there are typos), and then notify us so we can lift the hold. However in this case it looks like that part is already taken care of.
