Allowing Users to Opt Back In
Sometimes users change their minds. They opted out, and now they miss receiving your emails. How can a user opt back in?
Three ways to allow a subscriber to opt back in are described below: through a hosted opt-in page, on your website (using Sailthru’s API), or via a triggered email.
Via Hosted Opt-In Page
If a user clicks the unsubscribe link in a Sailthru email they have previously received, this will direct them to the Sailthru-hosted opt-out page.
The optout page will check the user’s profile:
{if profile.optout=="all"}
Then it will display an option to click to opt back in.
Via Your Website + API
If you use Sailthru’s API, you could follow these suggested steps in order to give users the option to opt back in by signing back up for email via your website. For example, when users click the “unsubscribe” link in an email and arrive on the unsubscribe confirmation page, you can provide a button for users to opt back in in case they clicked unsubscribe link in error.
optout_email
with a value of none
. This will reset the user’s status to valid.Via Triggered Email
Alternately, you could follow these suggested steps in order to send a triggered email to the user that would allow them to click a confirmation link within the email in order to opt back in.
a href="{signup_confirm()}"click here to opt back in.
If you use Sailthru’s Purchase API, please also see force send for purchase receipts.

If a user has hardbounced, not opted out, then the above will not work. Please contact Support or your Customer Success Manager with questions.
