Email Signature Support: All Supported Software

Can I use Email Signature Rescue?

Generally, if you can install a HTML email signature in your software, you can use Email Signature Rescue.

Unlike many of our competitors, our email signatures are non-software specific, meaning you can create and install our HTML email signatures across multiple email software programs and apps like Gmail on Webmail, Outlook on Windows, Apple Mail on macOS and even iPad and iPhone on iOS!

My software isn't on the list

If your software is not on this list, it doesn't mean that it's not supported. It just means we haven't tested for it and can't offer any help with installation issues. If you can install a HTML email signature in your software, it will work for you too.

Please don't hesitate to contact us if you have any questions about your software and apps and their compatibility with our email signatures.

Why do some online email clients require a Browser Extension?

Outlook.com, AOL Mail and Yahoo! Mail all have character limits on their email signatures and require our Browser Extension to install your email signature to bypass these limits. You can find out more about character limits in email software here.

How do we test our email signatures?

Before adding our email signature templates to our software, we test them extensively in-house across all of our supported email clients, and we continue to test them as new versions of email software is released. There can be some slight variations on some email programs that are beyond our control, however our code is the best possible HTML code to work across all the major email clients, as shown below.

Know of an email client that supports HTML email signatures that's not on our list?

If you know of any new email apps or email client software that supports HTML email signatures, let us know!

Why can't I send HTML email signatures from my Android Mobile/Tablet/Device?

There is now a select few apps that allow you to send true HTML email signatures from your Android device! See the above list for more details. Most other ones only support Plain Text email signatures.

We have found sending email signatures from mobile devices is a little more complicated. The native email apps on your Android devices simply do not support the HTML functionality that we need. We are looking into a better way to manage email signatures for Android devices in 2014 and hopefully (fingers crossed!) we can find a solution.

Why are there character limits on some Web-based email clients like Outlook.com, AOL Mail and Yahoo! Mail?

We now have a browser extension available that allows you to override the character limits enforced by these clients. Read more here.
