The Best Online Fax Services of 2019

Adam C. Uzialko
January 2, 2019

Faxes were once a central part of business communications, but they've surely gone the way of the dinosaurs since the digital revolution, right? Wrong. While email has largely taken the reins from the fax-centric business of yesteryear, many companies still need to send and receive faxes, whether for regulatory compliance purposes or keeping sensitive information off a potentially vulnerable network. Sometimes, faxing is even just a matter of convenience if one party still prefers to use it.  

Whatever your reasons for needing a fax service, you probably don't want a bulky, expensive and finicky machine taking up a sizable corner of your workspace. Online fax services digitize the faxing process, offering you an email-like inbox in which you can send, receive and store documents easily.

Want to take a step back and learn more about what to look for in an online fax service? Check out our buyer's guide first.

Our Methodology

To determine the online fax services we think are best for small businesses in 2019, we spent dozens of hours researching the top companies. Here is an explanation of our selection process.

Locating the Best Services

Business News Daily's substantial research into various online fax services, plans and features began with building a comprehensive list of vendors that offer online faxing. Through our own research, as well as other lists and reviews of popular vendors, we ended up with a list of 25 online fax services to examine further.

Choosing the Best Services

From there, we visited the websites of each fax service to compare pricing and features. We watched product demos and tutorials, and sent sample faxes when that feature was available. We used these criteria to narrow down our pool of candidates. Those that made it to our shortlist for best picks include Best Free Fax, Fax.plus, Faxx.us, Faxage, FaxBetter, Fax Zero, GotFreeFax, HelloFax, mFax, Nextiva, RingCentral and SRFax.

Researching Each Service

Next, we contacted all the services we were considering, calling and posing as a customer when possible. We wanted to get a feel for how the companies handle actual customer interactions, so we asked each customer service rep the same questions about features, options and pricing, and we noted our reactions to the experience.

Analyzing Each Service

For our best picks, the decisions came down to which companies offer the best balance of affordability, full features and ease of use. We shied away from vendors that offer low upfront pricing with lots of hidden fees or high overlimit fees. We used these criteria to evaluate each online fax software provider: ease of use, variety and features of plans, pricing structure, fax limits and overage fees, mobile access, international and toll-free faxing, and contract requirements.

Online Fax Service Trends to Watch in 2019

The online fax service industry is expected to continue its growth, demonstrating that businesses do indeed still have a need for faxing solutions. According to Arizton, the industry should eclipse $2.4 billion in value by 2022. That growth will be largely driven by North American and European companies, many of which are in the highly regulated healthcare and financial industries. The shift from conventional fax machines to online faxing will continue to be motivated by reduced upfront and maintenance costs, scalability through a SaaS model, and a desire for more automation in day-to-day operations.  

The online fax service industry is a crowded and competitive space, but it is likely ripe for consolidation. Some companies have made acquisition a prominent focus within their strategy, including J2 Global, which owns big-name brands such as eFax, MetroFax and Fax.com.
