Which one is for you

Pick EtherFax if

  • Fits if you are a hospital or clinic swapping faxes with Epic or OnBase
  • Works for agencies that need a FedRAMP-listed fax service

Look elsewhere if

  • Not for you if you want a price before you talk to anyone, because none is published
  • Skip it if you are one person who wants to sign up and send a fax today
  • Watch out: email faxing is described for Microsoft 365 and Google Workspace users only
  • Watch out: it is pitched at organizations and workflows, so a small office may find it more than it needs

Pick Phaxio if

  • Fits if you're a developer who needs to send faxes from your own software
  • Works for low-volume senders who don't want a monthly plan

Look elsewhere if

  • Not for you if you don't write code, because the main way in is the API
  • Skip it if you want a free trial, as there isn't one
  • Watch out: the API allows one request per second per account unless Phaxio raises it
  • Pricey if you send a lot: volume rates only start at 50,000 pages a month

How we grade them

2.0GPAEtherFaxFair1.8GPAPhaxioWeak
Value for money
CNo price is published, so it sits in the middle of online fax tools, which start at $6.99 a month for the cheaper quarter.
B7 cents a page in the US and Canada with a $10 minimum top-up and no monthly fee. A receiving number is $2 a month. Light senders pay far less than a plan; volume rates start at 50,000 pages.
Free plan and trial
FNothing free is listed: no free plan and no trial, only a contact-the-company route.
FNo free plan and no trial. You start by topping up $10.
Features
BEngage for sending and tracking, Flow for AI routing, a REST API and printer firmware integrations cover the job. The listing names no gap in it.
CA JSON fax API with batching, retries, callbacks and metadata, plus numbers for receiving. It does that job fully, and it is a smaller job than a full fax service.
Ease of use
CNo store rating is on record and it is sold to organizations, so setup means talking to the company and connecting your records system.
DNo store rating on record. You need to write code to send a fax, and a person with no developer won't get far.
Platforms and integrations
BWeb only, but with Epic, OnBase, Teams, Slack, Microsoft 365, Google Workspace, Canon and Ricoh integrations, plus an API.
BWeb console plus the API, which is the product. Phaxio says it can serve HIPAA workloads if its guidelines are followed. No phone or desktop app.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
