  (Asked by: username_0 on 2018-06-16)
  
  I have a contact which is a member of 2 groups and the status is "Added (by Email)" - i don't want this to be possible!
  
  on the same day, the account i use for bulk email received a (no subject) email from the relevant contact to civimail+u.1421.81227.ac26f752ec18f10b@
  
  The IDs of the groups in question are 14 and 10.
  
  in civimail accounts i have a default "bounce processing" with localpart "civimail+" account which i understand is for all bulk sending.
  
  I also have one without a localpart used for "email-to-activity" - i don't think i actually want this at all now i look, but it's there currently.
  
  What is triggering the "added (by email)" group join, and how can i block it in the future?
  Thanks!

  Added (by Email) is normally added when a contact is added to the group using a subscription URL provided in any mail.
  
  It is basically used to know how a contact was added to the group. This information is stored in `civicrm_subscription_history` table(`method` column) in civicrm database.
  
  If you want to simply remove `Email` method from your DB, you can do it by a simple SQL -
  
  ```
  UPDATE civicrm_subscription_history SET method = 'Web' WHERE method = 'Email'
  
  ```
  
  To avoid it in future, you can proceed in writing an extension and a post hook which updates `civicrm_subscription_history` after a group contact is created.
