Why trust us about online fax services? 

We’ve researched and evaluated online fax services since 2006. We’ve identified the most relevant and unique features for each service and made our recommendations based on our experiences while using the mobile and online interfaces like a typical customer. We also contact customer support teams and ask important questions about the feature tiers, pricing information and various technical aspects to make sure we recommend services with comprehensive and timely support.

Important features of online fax services

Mobile app
You can use an internet-connected mobile device to send faxes with all the services we reviewed. If you plan to primarily use a phone or tablet to send and receive faxes, we recommend choosing a provider with an accompanying mobile app. Using a web browser to access an online portal is much more frustrating than navigating an application built for a mobile platform.

Security and encryption
If you plan to send and receive sensitive information, like healthcare records, bank statements or other confidential personal information, make sure the service you choose specifically mentions HIPPA compliance and enhanced security measures like PGP and SSL encryption. Wilfully sending personal medical information through unsecured channels could result in fines of up to $50,000.

Plan flexibility
Analog fax machines are becoming obsolete, because online fax services offer a more affordable and user-friendly platform. For fledgling small businesses, it’s hard to know how long and how frequently you need to use an online fax service, so plan flexibility is important. If you are unsure how frequently you need to use it, we recommend taking advantage of free trial periods, and once you find the service that fits your needs, starting with the lowest tier plan. Service providers are much more willing to upgrade than they are to downgrade a plan, and comprehensive tracking features make it easy to keep a close eye on usage.
