What Is Email-to-Fax?
Email-to-fax is a technology that converts an email message into a fax transmission. Instead of printing a document and feeding it into a fax machine, you simply send an email with your document attached. The email-to-fax service receives it, converts it to a fax-compatible format, and transmits it over phone lines to the recipient's fax machine.
This means you can send a fax from any device that can send email — your laptop, phone, tablet, or even a smart watch.

Tips for Sending Faxes via Email
- Use PDF format — PDFs preserve formatting perfectly. Convert Word docs to PDF before attaching.
- Include the country code — Use the full international format: +1 for US/Canada, +44 for UK, etc.
- Check your attachment size — Most services accept up to 20MB. Compress large files.
- Use the subject line for the cover page — Many services (including Fax.plus) use your email subject as the fax cover page title.
- Keep it black & white — Fax machines render in B&W. Use high-contrast documents for best quality.
Is Faxing via Email Secure?
Yes, when using a reputable service. Fax.plus offers:
- TLS 1.3 encryption for all email-to-fax transmissions
- HIPAA compliance — critical for healthcare providers
- SOC 2 Type II certification — enterprise-grade security

However, standard email (SMTP) is not end-to-end encrypted. If you're sending highly sensitive documents like medical records, consider using the Fax.plus web app or mobile app with direct TLS encryption.
