Adding an Android email signature can be a pretty complicated process. If you use the Gmail app and want to change your mobile signature, then your email signature options will be very limited.

If you’ve ever tried to do this, you’re probably wondering how you can add a colorful, engaging email signature banner complete with interactive links. This can work wonders for promoting your brand and enhancing your email communications.

To do this, you’ll need to add an HTML email signature.

In this guide, we’ll explain step-by-step how you can add an Android email signature. We’ll also reveal some of the best apps to help you incorporate an HTML signature into your Gmail account using your Android device.

  1. Open the Gmail app on your Android device

While it’s easy, there’s no option to add an HTML email signature through the Android app. If you want to do this, then you’ll need to use a third-party app on your Android phone.

Why use an HTML Android email signature?

Using a plain text email signature is seriously limiting. These signatures don’t only look dull, but they won’t help you achieve any actions from your recipients.

The major advantage of using an HTML email signature is that it lets you add links and interactive elements to the signature.

Instead of just sharing a banner under your name or using a written sign-off, HTML signatures let you add multiple elements like social media links, QR codes, your website URL, contact numbers, or even GIFs animated. This makes these email signatures more interactive and more engaging – which can be a great tool for marketing your brand.

By using an HTML signature tool, you can create a great-looking email signature. Then you will just need to copy the HTML code into your Android device. These email signatures will load well, and they will make your emails look a lot more exciting and professional.

The right email signature tool will let you access a wide variety of HTML signature designs and possibilities so that you can create a great-looking signature that reflects your brand.

How to add an HTML signature on the Gmail mobile app

The simple text email signature won’t help you achieve much. Instead, you’ll want to use an HTML Gmail signature, which will help you achieve a lot more with all of your email communications.

The Gmail app does not support HTM signature input – it’s text only. So, you’ll need to install an alternative app for adding HTML email signatures.

Here are three examples of options you can use on your Android device.


Fastmail homepage

Fastmail is an email platform that can be used as an alternative to the Gmail app. You can use the platform’s Gmail transfer tool to easily add your Gmail account information, which you can manage through Fastmail.

There are many advantages of using Fastmail, such as enhanced privacy, access to various tools that can enhance your email productivity, as well as fast support through the app. However, the reason we’re mentioning Fastmail is that it lets you add an HTML email signature.

To complete this, simply import your Gmail account information to Fastmail. Then you can use the intuitive app to change your email signature. Unlike Gmail’s native email app, it gives you the option to paste in HTML code for your signature.


ProtonMail homepage

ProtonMail is another email service with a great email app. Just like Gmail, ProtonMail includes tools for managing your email, calendar, and drive. There’s also a VPN tool.

Users also enjoy the platform for its high levels of security and privacy. All email used through this platform is encrypted, which makes it private by default. In fact, ProtonMail is the largest encrypted email service in the world.

Besides these helpful features, though, you can use ProtonMail to set up your Gmail signature. ProtonMail lets you set up an email account from another provider. You do this through the “External Account” feature.

Once you’ve added the external account, you can manage your Gmail account just like you would through the Gmail app – except that you can also add an HTML short code when updating your Gmail signature through the ProtonMail app.


OnMail’s app is really easy-to-use, and it lets you access a few helpful features that you can’t get with Gmail. One of these is the ability to add an HTML email signature.

Just like the other two platforms listed above, you can add your Gmail account to OnMail, and send emails using your original email address. Recipients won’t see that you’ve switched to OnMail, yet you can benefit from the platform’s unique features.

Make sure you use the proper platform to create and manage your email signatures, and use an email provider that supports HTML signatures. It’s pretty simple to get right and can make an enormous difference to what your email communications help your brand achieve.
