While it might not be necessary for personal emails or when you’re sharing funny cat videos with family members, a lot of Gmail users like to have an email signature for business reasons. Rather than typing out your phone number or contact information every time, Gmail will do all the legwork for you.
Since this isn’t a default option, you’ll need to head into your Gmail settings to add or change an existing Gmail signature.
How to add a signature on your desktop
Step 1: Launch your favorite browser and log into your Gmail account as you normally would.
Step 2: Next, click the cog icon in the upper-right corner of the screen and click Settings from the drop-down menu.
Step 3: Under the General tab, scroll down until you see Signature. Click on the Create new button.
Step 4: In the dialogue box that pops up, enter a name for your new signature. Then you’ll be taken back to the Settings screen and a new text box will appear next to your signature’s name. Type your desired email signature into this text box.
Optional: Below the signature field, you’ll see a checkbox that allows you to add your signature before quoted text in email replies. This will make your signature more visible in email threads. It’s worth toggling on if you’re using your email for professional correspondences, or if you want your signature to remain visible in follow-up messages. This section below the signature field also contains two other drop down-menu options that allow you to choose if your signature shows up in new emails or in replies and forwarded emails.
Step 5: After you’re satisfied with your signature, scroll to the bottom of the page and click the Save Changes button. That’s it! Your signature will now appear on all new messages and outgoing mail.
If you have an email address from Yahoo, Outlook, or another email service, you can also send emails via that address using Gmail’s “Send mail as” feature. You can set that feature up from within your account settings, and once you do, you’ll be able to create a different signature for that email address. Just click the drop-down menu that appears underneath the signature field and choose your preferred email address from that menu.
How to add a signature on your Android or iOS device
Email is no longer reserved for the desktop iteration of Gmail, especially in today’s world of mobile computing. You can also add a signature to all outgoing emails directly on your smartphone using the Gmail app for Android and iOS.
Keep in mind, however, that the app is a bit more restrictive when it comes to customization features. Your signature will also only appear if you’re using your smartphone to send messages — you will have to set up the desktop signature separately.
Step 1: Download and launch the Gmail app as you would normally.
Step 2: Tap the three horizontal lines in the upper-left corner.
Step 3: Tap Settings in the resulting pane.
Step 4: Tap on the account you want to add a signature for.
Step 5: For iOS devices: Tap Signature settings and toggle the slider beside Mobile Signature. For Android devices: Tap on the Mobile Signature option, located under the General section.
Step 6: Add your desired signature.
Step 7: On iOS: When finished, tap Back to save your newly-minted signature! On Android: When finished, tap OK.
