Gmail allows you to create a default signature which will be added to each message you compose. You can format the signature text and add images e.g. company logos. You can create additional signatures to add to messages as required.
Note: Your Outlook signature will not be migrated to Gmail so will have to be recreated.
To create a new signature:
Click on the Settings cog near the top-right corner of the Gmail screen
Choose See all settings
Scroll down to the Signatures section
Click on Create New
Type a name for your new signature
Enter your signature text in the large box
Format text by dragging the mouse over the text to select it, then use the buttons on the toolbar to change the format of the selected text (see table below)
Add an image by clicking on the Insert Image button.
You can add an image from a folder on Google Drive, or click on the Upload link to upload an image stored on a local drive on your computer. In addition, you can click on the Web Address (URL) link to add an image by entering the URL at which the image can be found on the web.
To add a link e.g. to your website, type the text to show in your signature, then select it and click on the Link button. Enter the URL for the link, then click on OK
Choose the signature to use by default for new messages you create, and messages you create in reply to received messages
Scroll down the screen and click on the Save Changes button
Use the toolbar along the bottom of the signature to format your text e.g. by adding bold, italics, colour or setting the alignment of text.
Ensure you tick the box to Insert the signature before the quoted text. This will stop the signature from displaying below any replies or forwarded text in your message, and show it at the bottom of your message text instead.
Click on Save Changes along the bottom of the screen when complete.
