Choose by sending pattern
Which kind of online fax service should you use?
Use a one-time service for an occasional outbound fax, a free service when its page and branding limits fit, or a subscription when you need an inbound number, storage, teams, or frequent sending.

What should I compare besides headline price?
- Whether an account, trial, credit balance, or monthly renewal is required
- Whether the service sends only or also provides a receiving number
- Maximum pages, files, file size, destinations, and supported formats
- Whether a cover sheet or provider branding is added
- How delivery status, retries, refunds, document retention, and support work
- Whether the service makes compliance claims relevant to your organization
Is the cheapest listed option always the lowest total?
No. Compare the total for your actual page count and needs. A free limit may be too small, a fixed per-fax charge may cost more for one page, and a subscription may be economical only when used regularly.
