Our top three

The three we'd look at first, and who each one suits

The three online fax services we'd look at first. First place suits the most people; second and third are the best picks for the people it leaves out. Each has an Insider's Guide of its own.

1. 1st

   

   3.0GPA

   Fax.Plus

   Free trial · from $6.99/mo

   For: Most people who send and receive faxes

   Fax.Plus sends and receives from any email inbox, a print menu, a browser and apps for Windows, Mac, iPhone and Android, with local, toll-free or ported numbers in 48 countries. Basic is $6.99 a month billed yearly ($8.99 monthly) for one number and 200 pages, and its iPhone and iPad app averages 4.7 from about 13,000 ratings. Know the limits: the free account sends 10 pages in total and cannot receive; Basic charges 10 cents a page over 200 and caps a fax at 60 pages; porting a US or Canadian number needs Premium at $13.99; and a signed HIPAA BAA, the API and Zapier need Enterprise at $79.99.

   2.2GPA

   Notifyre

   From $4.90/mo

   For: Occasional senders, and offices that need a signed BAA

   Notifyre charges 3 cents a page to send within the US from a prepaid wallet, with no subscription, and a fax number to receive on starts at $4.90 a month for 200 pages. It says every account is HIPAA compliant with a free BAA, and it adds email to fax, free number porting, audit trails and a fax API. It is second because there are no native apps, only an installable web app; there is nothing free to fax with and no trial; sending needs a $10 minimum top-up and is billed apart from receiving; and 3 cents applies only within the US, with high-quality sending 25% more.

   2.8GPA

   eFax

   Free trial · from $15.83/mo

   For: Offices that want a BAA plus phone and Windows apps

   eFax sends and receives by email on every plan, in a web portal, from a Windows print-to-fax app and from iPhone and Android apps that can sign a fax before sending, and it keeps past faxes in searchable storage. Business is $33.33 a month billed yearly for five users, 500 pages, pages to 51 countries and a signed BAA. It is third because Personal costs $15.83 a month billed yearly for 200 pages, more than twice Fax.Plus's Basic, and covers only the US and Canada with no BAA; there is no Mac app; extra users on Business are $10 a month; and the API is on Corporate, priced by sales.

   The eFax Insider’s Guide

Some software does something you couldn’t reasonably build yourself. Some is simple enough that an AI app builder could make the core of it in an afternoon. Here’s where online fax services land, by the same rules for every tool.

• 11

  Keep it

  It does something you could not reasonably make for yourself, or it costs nothing.

• 0

  Your call

  You could make the core of it, and you would give something up.

• 0

  You could make this

  What it does is the kind of thing an AI app builder makes well, and it charges every month.

Every online fax service we grade, with its GPA and what it costs. Each one has a page of its own on toolgpa.com, with its Insider’s Guide.
