When you need to locate and edit a subscription that you added to Unroll.Me, you can use the built-in search feature available in the Unroll.Me mobile app or the desktop website.
It's important to note that the app and desktop website searches subscriptions by domain among the first 100 subscriptions. Therefore, if you have more than 100 subscriptions, you will need to select a tab where you want to search by email or sender (Kept, Unsubscribed, Rollup) and scroll down to the bottom of the subscription list.
Once all the subscriptions have loaded, you can begin your search by domain. This will help you locate the subscription you need to edit.
