Yes. It is possible to remove the signature without compromising the functionality of MailTrack. In order to do this, you can:
1. Remove the signature from the emails in which you do not wish to include it (all you have to do is select the text and delete it).
2. Alternatively, if you want to take the signature off by default, you must go to https://mailtrack.io/es/dashboard/settings/edit and unmark "Signature".
