Google’s Gmail service supports configurable signatures that are attached to any email you send. You can add your name, job title, social media details, phone number, or anything else you want to your signature.
There are two types of signature: web signatures sent from Gmail on the desktop and mobile signatures sent from Gmail on your phone.
Add a signature to Gmail on the web
To add a signature on the Gmail website, open Gmail and click the Settings icon in the upper right corner. It̵
Click “Show All Settings” to open the full settings menu.
Scroll down most of the page until you find the “Signature” option and click the “Create New” button.
Give your signature a name, then click Create.
Enter whatever you’d like in the box to the right of your new signature. This is where you’ll often add your name, place of work, and possibly your phone number or social media accounts.
Under the text editor where you just added your signature, under the Signature Defaults section, click the name of your email signature to add it as the default signature for new email.
Do the same in the box to the right of the last one to use your new signature as the default option for replies and forwarded emails.
Click Save Changes at the bottom of the page to save your new signature.
You can add multiple email signatures and switch between them too.
Adding a mobile signature
You can also add signatures that are specific to mobile devices. These signatures will overwrite the desktop versions you just added. In other words, when you send an email from a device with a mobile signature, Gmail just sends the mobile signature and ignores your desktop signature.
You can use these signatures for anything, but the common practice is to create one that will alert people that you are on a mobile device so they know you may be slower to respond (when you are out of the office) or that this will be typo due to overzealous autocorrection.
Of course, you can also use the desktop signature for all of your devices. You don’t need to set up a separate mobile signature.
To set up a mobile signature, open the Gmail app on your mobile device – iPhone, iPad, or Android.
In the top left, tap the hamburger menu.
Select the “Settings” option in the sidebar.
Tap your profile photo or email address to open the Signature Settings menu.
If you’re using an iPhone or iPad, tap Signature Settings on the next page. Instead, tap Signature on Android.
If you’re using an iPhone or iPad, toggle the mobile signature switch to the right to enable mobile-only signature.
Add your text and close Gmail to save your new mobile signature.
You now have a cell-only custom signature that will only appear when using Gmail on a mobile device. Your desktop signature will be retained even though Gmail defaults to using the mobile signature on your phone or tablet.
