FROM MESSAGE TO FAX-READY DOCUMENT
Write it. We’ll take it from there.
Your words become the document.
The address tells us where it goes.
Your message becomes a PDF.
We turn the email body into a clean document. Longer messages flow across multiple pages. You don’t have to create or attach the PDF yourself.
We relay it to eFax.
The PDF goes to the matching number at efaxsend.ca from our dedicated relay address. eFax handles the onward fax transmission.

Who can send a fax?
Fax relay is available only to explicitly approved sender addresses and must be separately enabled. Fax sending is not currently enabled on this deployment. The PDF preview is a separate way to check the document format.
Do I need to connect my mailbox?
No. You send an ordinary email from your existing app. AttachThis doesn’t log in to your mailbox or read your other messages. Your sending address must pass email authentication checks.
What is included in the relayed PDF?
The text of your email body. HTML-only messages are converted to text. Original attachments, remote images, and decorative formatting are not included. Keep the email under 1 MB and its body under 40,000 characters; beta rate limits also apply.
Does a submitted email mean the fax arrived?
No. Relay submission and successful fax delivery are separate events. Delivery must be verified with eFax; automatic fax delivery tracking is still being built.
Your message. A PDF. On its way.
