How can I remove my address from my emails?
By editing sender details in the footer
To be clear, it's not really possible to remove your business address from commercial email messages. It's a legal requirement in many countries like the US, so you need something. But, if you're running a small business from home, well, blasting out your street address isn't really a good idea.
There are options that can help you get a legit business address, like renting a post office box, a physical mailing address from a business, or a virtual mailbox.
