Google’s Gmail service supports configurable signatures as it is attached to every email you send. You can add your name, job title, social media information, phone number or anything else you want to your signature.
There are two types of signatures: web signatures sent from Gmail on your desktop and mobile signatures sent from Gmail on your phone.
Add a signature to Gmail on the web
To add a signature to your Gmail site, open Gmail and click on the “Settings”; icon at the top right. This is the small gear-shaped icon near your profile picture.
Click “See all settings” to open the entire settings menu.
Scroll all the way down the page until you find the “Signature” option and click the “Create New” button.
Name your signature and then click “Create”.
Write everything you want in the box to the right of your new signature. This is where you often add your name, place of employment and perhaps your phone number or social media accounts.
Under the text editor where you just added your signature, in the “Signature Default” section, click on the name of your email signature to add it as the default signature for use with new emails.
In the box to the right of the last one, do the same 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 as well.
Add a mobile signature
You can also add signatures that are specific to mobile devices. These signatures override the desktop versions you just added. In other words, when you send an email from a device with a mobile signature, Gmail only sends the mobile signature and ignores your desktop signature.
You can use these signatures for anything, but it’s common to create one that alerts people that you’re on a mobile device so they know you’ll be slower to respond (unless you’re in the office) there may be spelling errors due to excessive auto-correction.
Of course, you can just choose to use the desktop signature on all your devices as well. You do not need to set a separate mobile signature.
To set up a mobile signature, open the Gmail app on your mobile device – iPhone, iPad or Android.
Tap the burger menu from the top left corner.
Select the “Settings” option in the sidebar.
Tap your profile photo or email address to open the signature settings menu.
If you are using an iPhone or iPad, tap “Signature Settings” on the next page. On Android, tap “Signature” instead.
If you are using an iPhone or iPad, toggle the Mobile Signature switch to the right to activate a mobile signature.
Add your text and close Gmail to save your new mobile signature.
You now have a custom mobile-only signature that only appears when you use Gmail on a mobile device. Your desktop signature will remain, but by default Gmail will be the mobile signature of your phone or tablet.
