Edison Mail's big 1.17.0 (iOS) and 1.12.0 (Android) updates introduce a new, powerful Assistant to the mix. Aside from the fresh calendar integration and extensive customizability, you'll probably be most interested in the Assistant's unsubscribe feature. It helps to locate and cut down on your inbox's ever-growing jungle of spam. Here's how it works.
The Assistant lives in the top right of the main email viewer. When you tap the option, you'll find all of the new Assistant tools (at least the ones you've activated) conveniently pooled into one location. If Edison's Assistant thinks there are any accounts in your inbox that are spam or unnecessary, it will list them under Suggested Unsubscribe.
Unsubscribing from spam is as easy as two taps. Under Suggested Unsubscribe, tap "No Thanks" on the ones you want to keep or "Unsubscribe" on the accounts you no longer want to hear from. For the latter, Edison will open a second window, with a list of recent emails from said account. If you wish to confirm the unsubscribe, tap "Unsubscribe" at the bottom. If you want to cancel, tap the "X."
Once you unsubscribe, the original contact is removed from Suggested Unsubscribe, with a subsequent account filling its place. Once you've gone through all of the options, Suggested Unsubscribe will disappear. While Edison does not send unsubscribe requests to the actual senders, it adds senders to the blocked list and all future emails from them will go straight to the trash.
Furthermore, you can always manage your subscriptions by opening the three-dash menu and selecting "Subscriptions" under Assistant. In the "Subscribed" tab, you can see everything you currently get with the option to "Unsubscribe" like detailed above. However, hitting that button blocks the sender right away, unlike the preview card that appears via the suggestions.
Any emails you unsubscribed to, whether via the suggestions, the "Subscribed" tab, or via the "Unsubscribe" link in individual emails directly, will appear in the "Unsubscribed" tab. If you ever change your mind, you can go here and hit "Resubscribe" to get emails from the sender again. You can also look at your "Trash" folder, select an email, then hit "Resubscribe" that way.
Edison's unsubscribe tool is much faster than hunting down spam emails one by one, and we like that the feature disappears when there are no spam accounts left. It makes it easy to check the Assistant quickly to see if there are any outstanding spam accounts in the queue. If so, taking them down is no issue. If not, you can carry on with your email, without so much spam crowding your inbox.
