A: Hey, cientiros!

Thunderbird... man, I used to love that back in the day. I used to use it religiously with Firefox for the perfect 1-2 combo. Glad you're still using such a great piece of software. 🙌

We do have both HTML and "visual" copy-and-paste ability, so you should be able to use one of those two methodologies to paste the signature. If you run into any issues, you can email support@emailbadge.com and we'd be glad to help you out.
