Email keep is a WordPress Plugin that will keep a copy of any emails sent by the website. It provides you with the ability to retain those contact attempts that never got delivered to your inbox because of issues with your hosting configuration and or contact form bugs.
For backwards compatibility, if this section is missing, the full length of the short description will be used, and 
Markdown parsed.
Features: 
 1. Capture email messages sent from the front end, admin or both. 
 2. Capture email messages with a specific keyword in the subject to limit the email capture to specific important emails, like anything with “contact” in the subject line. 
 3. Ability to soft delete messages and also restore deleted messages.
