This article contains instructions on the old version of Elastic Email dashboard. If you would like to see the new dashboard version of this article, please use the following link
There are two methods of resubscribing a contact:
Method #1 - Web Form
Add the contact via a Web Form that you can create with the help of Elastic Email (learn more here).
Method #2 - Subscription link
Go to your Elastic Email account's Settings "Unsubscribe" tab. Here you will find a "Subscription link" that you can copy and forward to your contact outside of Elastic Email. Once clicked, the user will be forwarded to a default subscription form.
With both methods, after the contact is added, they will be sent an email with an activation link - when the link is clicked, the contact's status will change back to "Active".
