While this may not be necessary for personal emails or sharing funny cat videos with family members, many Gmail users want to have an email signature for business reasons. Instead of entering your phone number or contact information each time, Gmail does all the work for you.
Since this is not a standard option, you’ll need to go to your Gmail settings to add or change an existing Gmail signature.
How to add a signature on your desktop
Step 1: Start your preferred browser and log in to your Gmail account as usual.
Step 2: Then click the gear icon in the upper right corner of the screen and click Settings from the drop-down menu.
Step 3: On the General tab, scroll down until you see Signature. Click the Create New button.
Step 4: In the dialog box that appears, enter a name for your new signature. Then return to the Settings screen and a new text box will appear next to your signature name. Enter your desired email signature in this text field.
Optional: A check box appears below the signature field, allowing you to add your signature in front of the quoted text in email replies. This will make your signature more visible in email threads. It is worth activating this option if you use your email address for professional correspondence or if you want your signature to remain visible in the subsequent messages. This section below the signature field also contains two other drop-down menu options that you can use to choose whether your signature will appear in new emails or in replies and forwarded emails.
Step 5: When 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 in all new messages and outgoing emails.
If you have an email address from Yahoo, Outlook, or another email service, you can also send emails from that address using Gmail's "Send Email As" feature. You can set this up in your account settings. Once you've done this, you can create another signature for this email address. Simply click the drop-down menu that appears below the signature field and choose your preferred email address from this menu.
How to add a signature on your Android or iOS device
Emails are no longer reserved for the desktop iteration of Gmail, especially in today's world of mobile computing. With the Gmail app for Android and iOS, you can also add a signature to all outgoing emails directly on your smartphone.
However, keep in mind that the app is somewhat more restrictive in terms of customization features. Your signature is only displayed if you use your smartphone to send messages. You have to set up the desktop signature separately.
Step 1: Download and start the Gmail app as you normally would.
Step 2: Tap the three horizontal lines in the upper left corner.
Step 3: In the area that appears, tap Settings.
Step 4: Tap the account for which you want to add a signature.
Step 5: For iOS devices: Tap Signature Settings and toggle the slider next to Mobile Signature. For Android devices: Tap the Mobile Signature option in the General section.
Step 6: Add your desired signature.
Step 7: On iOS: When you're done, tap Back to save your newly minted signature! On Android: When you're done, tap OK.
