Webform emails threading I have a client Webform and I use a custom template for delivering the submissions to the Gmail inbox. I've set the sender's email to the component e-mail field. 

The problem is that Gmail puts all the received emails into one thread as if though the sender is the same for all the emails. So it becomes impossible to manage the clients emails as everything is being mixed up.

Is it a Webform configuration or am I missing something?
This isn't really a Drupal question. Go to https://mail.google.com/mail/#settings/general and look at the Conversation View. This sets whether emails of the same topic are grouped together. So they aren't grouped together based on the from: address but on the title. Just set it to Conversation view off and save the settings.

Alternatively, make the subject of the mail unique. For example by adding the name or email address to it, or a unique key.
