Personalization of the signature
In the window dedicated to customization, you can :
customize the text
edit / change HTML
We advise you to use a signature without images for your sequences in order to increase email deliverability.
Too many clickable links may disperse your prospects when reading your emails. Unless the link that is in your signature redirects to a landing page with a form, and that would be your call-to-action :)
