# SingleFax Email to Fax

HTML: https://singlefax.com/email-to-fax

Email a supported document to **send@fax.delivery**. Put the destination fax number in the subject. US numbers can be 10 digits or `+1…`; other countries need a country code (for example `+441234567890`).

PDF, Word, Excel, PowerPoint, RTF, plain text, and images (JPEG, PNG, TIFF, GIF, WebP, BMP, HEIC). We convert to PDF before sending. Up to 10 attachments. Raw email is limited to 10MB.

Same retail pricing as the website: **$0.99** for up to 10 billable pages, then about **$0.08**/page (cap 100). If you already have credits, we send the fax right away; if not, we email you a payment link. No account required.

Use a real mailbox (SPF/DKIM). Disposable addresses are blocked.
