With 1Tool you can create your own email signature.
The e-mail signature can be found under the user settings if you click on your name at the top right and then scroll down under the user settings in the first tab.
In the overall view that now appears, you will find all existing e-mail signatures.
You can now edit and delete these. You can create a new signature by clicking on “Create signature”.
Here you can now edit your existing signature or create a new signature. To do this, simply enter the desired shape and then click on Save or when creating another signature on “Save and create new".
