Ancoris Signatures syncs email signatures via the Gmail API, this means, if your mobile or other client supports pulling the signature from Gmail, the signature configured in Ancoris Signatures will be available.

Currently we are aware that the Official Gmail mobile apps for Android and iOS don't pull Signatures from Gmail or support HTML signatures so will not work with our product, similarly other clients such as Google Inbox and built in iOS clients don't support Gmail signatures either.

The Gmail web interface does however support HTML signatures.
