You can send a fax through Gmail with an online fax service that integrates with Google products. Fax.Plus has a Google Fax feature that’s a fast, free, and secure way for all Fax.Plus users to send a fax through Gmail.  To enable faxing through Gmail, you need to register a Fax.Plus account and install the Google Workspace extension through Fax.Plus. Once integrated, you can send a fax through Gmail by putting the recipient’s fax number, followed by @fax.plus, in replace of a traditional email address.
