I just found something interesting which I would like to share. Now with the help of lab gmail created a feature to change your default font. I would like to send my emails in Trebuchet format. I used to select the font every time I send the email.
Select your lab feature enable “Default text styling” after that change your font style in the general tab of settings.
Ahaa… good info buddy
Much better if it was also applicable to the Email Signature content which we can set in the settings.
