Tips for Fastmail Signatures
- Use the HTML editor (not the rich text editor) for best results with our templates
- Images must be hosted externally — Fastmail doesn't host signature images
- Test by sending an email to yourself after setting up
- Fastmail mobile apps will use the same signature you set on the web
