Google automatically rewrites the “From” field of any e-mail you send through its SMTP servers to the default address set up in your Gmail account, even if you don’t send the mail directly from Gmail. If you’re not careful, this can tarnish your business image. This small quick fix has to be done before you start sending e-mails to help you keep your branding consistent.
Start by signing into the Gmail account you use with Google SMTP. Click the gear icon in the top left corner, then choose Settings. Select the Accounts and Import tab. Look at the Send mail as section and make sure you have more than one e-mail address set up. If you don’t, add another account, preferably one personalized with your business branding. Now simply make this your default account; Google’s SMTP will automatically rewrite the From field using this address instead of your Gmail account. It’s that simple!
