If your default message format is "rich text", the signature text box will also be rich text, allowing you to change fonts and colours, and add links. You can change your default message format on the Settings → Preferences panel in the settings.
How to create a signature with an image
Use the image icon to insert an image into your signature. The image must already be available on the internet: you can't upload a file into the signature editor.
Make sure you have permission to use the picture you are linking to. You'll need to think about:
- Copyright and fair use limitations.
- Can I use that picture? is an infographic showing when you can and can't use images.
- When your email is viewed, the recipient's mail client will request the image from the remote web server. If your mail is going to many recipients, the image host may not want you using up their bandwidth.
- Unexpected image changes.
- If you don't own the image on the remote host, the remote server can remove or change the image at any time, causing your image signature to change without you doing anything.
One way to avoid the issues with remote hosting is to upload the image to your file storage and linking to your own Fastmail website. If you are part of a multi-user account, an account administrator will have to upload the files on your behalf and let you know of the website URL to access your image. Remember that images hosted through your file storage in your signature will contribute to your Fastmail download limits.
Alternatively, you may wish to use an image hosting service, if you know your image signature will be viewed many times and use a lot of bandwidth.
