If you have been manually rewriting a work and a personal signature every time
If you send both work and personal email from the same account, instead of manually changing your signature each time, you can create several signatures in advance and set them to apply automatically to new messages or replies based on the situation.
Mobile signatures are managed separately
Signatures set up this way in Gmail on desktop do not automatically carry over to the Gmail mobile app β the app has its own, simpler signature field under its settings menu, which only supports plain text and does not sync with the multiple, HTML-formatted signatures you build on desktop. It is worth checking and updating the mobile signature separately if you use both.
Frequently Asked Questions
Can I switch signatures while I'm already composing a message?
Yes. Clicking the signature icon at the bottom of the compose window lets you instantly switch to any signature you have already created.
Is there a limit to how many signatures I can create?
There is no specific limit stated, but since too many become hard to manage, it is more practical to keep it to two or three that match the situations you actually use.
