Should your whole signature just be one big image?

By EmailArt team

Every few months someone asks: can I just export my signature as a single PNG and paste that in? You can. Please don't.

What breaks

Screen readers announce "image" and stop
Recipients can't copy your phone number or email
Clicking your name doesn't open a new email; there is no link
Gmail flags image-heavy signatures as potentially promotional
Retina scaling makes text soft on high-DPI displays

The right mix
