Do you want to trigger Gravity Forms e-mail notifications when updating an entry, even when using GravityView to update entries from the front-end of your site. You can download the Entry Revisions plugin to get that option.
Add New Notification
The Gravity Forms Entry Revisions Add-on from GravityView adds a new ‘Entry is updated, revision is saved’ notification event and sends those notifications directly after an entry is updated. It is compatible with GravityView for front-end entry updating.
