Protonmail: How to Add a Custom Signature

Many companies choose to include a custom email footer in all emails sent from corporate accounts. This data is sent via a feature known as an email signature. The signature is automatically applied to the end of any message that you send. Signatures can be used for more than just including corporate images and disclaimers.

When writing emails, you often end up signing off the email, in the same way, most of the time. You can save yourself the time of doing so and having to check for typos by adding your sign off to the email signature. This works for both corporate and personal email addresses.

If you’re using a ProtonMail email account, you can configure your email signature in the settings of either the web application or in the mobile app. To change your signature in the mobile app you first need to tap on the burger menu icon in the top-left corner, then tap on “Settings”.

In the settings tap on your account name at the top, then tap “Display name & signature”.

In the “Signature” box enter the text that you want to be automatically attached at the end of your message, then tap the slider to the on position.

Tip: The signatures are simply pasted a few lines into the email creation box when you first click “Compose”. The mobile signature and its counterpart on the website are always applied unless you pay for one of the premium tiers. As the signatures are applied when you first start the email, you can easily select and delete them if you don’t want them to be included or if you want to change them.

On the website, the process is essentially the same as the mobile app. Click on “Settings” in the top bar, then type in the “Signature” box, which can be found in the top left section of the default “Account” tab. Once you’ve made the changes you want to your signature, click “Save” to save your change.

Tip: The value of the “Signature” box is synchronised across platforms, whereas the “Mobile signature” and “ProtonMail Signature” boxes are unique to their respective platforms.
