There are two standard methods for receiving consent from your recipients. The first and only recommended way to get consent is a sign up form (email your recipients with a link to go fill out that form on your website).
n alternative is a permission pass email, but it must closely match your usual content. A simple request for confirmation may be flagged as sending without proper consent, which can hurt deliverability. Including your normal content along with a consent link helps avoid this issue.
A permission pass email typically includes a link such as “Yes, I consent,” which directs recipients to a page confirming their subscription. The page itself should clearly acknowledge that their consent has been recorded and that no further action is needed.
It’s recommended to wait 24–48 hours before collecting clickers to allow late recipients time to view and provide consent.
