I am still struggling with this today - And I'm very frustrated with customer support on this issue. At least this thread provides some options which I will try.

Please consider an editor or integration with any of the apps mentioned by earlier comments.
Requiring your customers to become programmers does not really address the opportunity presented by this suggestion. Happy with Nimble, frustrated that i have to use Gmail to preserve my email signature with its links to linkedin, houzz, pintrest etc...

Gary, thank you for sharing this link, our users will find it very helpful.

Hey guys!

I already found an amazing converter from our signatures from gmail, hotmail, etc. to html:

Just copy your signature and press "fuente HTML"

If you need it now please use it :)

Greetings!

Not very user friendly though...

Please integrate WiseStamp Email Signature to include Social Icons.

Integration with Brand My Email would overcome this issue

good idea and have an ability to paste an html code also

i need the ability to have multiple email accounts represented in both the signature and the outgoing email.

Wisestamp integration, no need to re-invent...

Wisestamp integration, please! =-)

And it would be nice just to be able to add even just a simple signature to messages sent through via Nimble through LinkedIn, FB etc. :-)

Good idea - you could even integrate with WiseStamp or similar.

Agreed entirely. The inability to format keeps me inside Gmail. You can't be all things to all people but this is a small barrier that pertains to still probably the biggest usage of an application like this - email.

I agree completely with the above request. As part of our idenity package we have this great e-mail signature that we can't use with Nimble. We would love to be able to upload it and have it on all e-mails.
