I have experimented with several signature creation tools, and this one is by far the easiest to use. The templates are a good starting place, and you end up with clean signatures.

I do have some concerns with deliverability. All the images and links in the signatures are served from https://mysig.io/ and since the "Welcome" and orientation mails from the company came from there and landed in my spam folder, I am not yet sold on the product. I am going to use it for a while and see what the impact is.
