Remove email signature after sending single email with email template

Question

here is the scenario.

UserA has email signature in his setting. When clicking on a custom button, a template email is sent out to Person_B with sender UserA's name. Now the sent out name has 2 email signatures. The email Person_B receives looks like below:

-------------------------------------------
|Templated content                         |
|                                          |
|User A                                    |
|Blabla                                    |
-------------------------------------------

Requirement is to remove the User A I'm the email signature text coming from setup-->Email setting.

Answer 1

depending on how you are sending the email (eg. javascript, Apex Callout) If you're using apex...

The SingleEmailMessage has the Email class as a parent class. Therefore you can use the method setUseSignature(useSignature) as outlined in the Email Documentation. When set to false the Users signature will not be added to the email.

I'm not sure if you could use this from javascript or as a parameter in the /EmailAuthor Url but here is some info on calling apex from a custom button
