Frequently asked questions

Adding the signature to your email client usually takes less than a minute.

How do I add this signature in Gmail?

Select “Copy signature”, then open Gmail Settings → See all settings → General → Signature. Create a signature, paste it, choose defaults if needed and save changes. Gmail’s interface may change.

How do I add this signature in Outlook?

Select “Copy signature”, then open Outlook Settings → Accounts → Signatures, or File → Options → Mail → Signatures in supported desktop versions. Create a signature, paste it and save. Outlook’s interface may change.

Is the signature compatible with every email client?

The output uses table layout and inline styles for broad email compatibility, but clients can sanitize or render HTML differently. Check the result in every client important to you. No scripts, external CSS or external fonts are added.
