Why was my Confirmation Message subject line rejected?

The Customer Solutions team review custom subject lines.

There are two requirements. First, you will need a call to action like "please confirm" or "verify that you would like more information..."

Secondly, remind your subscribers what they signed up to receive.

For example,

"Please, confirm your subscription to [your business name here]"

You can edit the confirmation message on the List Settings page.
