Good to know

  • Gmail limits signatures to 10,000 characters of HTML. Sendoff shows a live counter so you never hit the error.
  • Images are served through Google’s image proxy. Use hosted images (Sendoff hosts them for you); pasted or base64 images are stripped.
  • The Gmail mobile apps use their own plain-text signature. Clear it so your web signature is used.

Copy, paste, done
