Which email programs are the best for email signatures?

We learnt a lot writing our installation guides for email signatures for different email programs. Here's our wrap up of what email programs we believe are the best for installing and sending HTML email signatures. Of course, our code works with a majority of them, but if you want to know which ones we think are the best, here they are:

If email signatures are important to you and your business, consider switching to any of the recommended email clients that we have provided here for you. There's some great email clients available on the market, both free and paid.

Our top pick is... Gmail

If you do a lot of business from your iPhone/iPad, consider using Gmail and the Gmail iPhone App. It's one of the best for sending HTML signatures from both your iPhone/iPad and desktop/laptop. Once your signature is setup in Gmail, if using the Gmail App too, the iPhone and iPad will automatically insert the HTML signature on send, without having to physically install it into the iPhone/iPad itself.
