What is the difference between FAX.PLUS and eFax?

Send a fax with electronic signature capability: FAX.PLUS users can digitally sign and send faxes using its convenient Android and iOS-based apps. eFax, on the other hand, is a device-agnostic online fax service that enables users to digitally sign documents through the easy-to-use website, mobile app or desktop app. With seamless access to advanced features like finger swipe technology, users can add an electronic signature and send time-sensitive documents within seconds. Where FAX.PLUS users are limited to editing pages via the mobile app, eFax users can annotate documents with contextual notes and markup tools through all connected devices.

Maximum supported file size: FAX.PLUS users can simultaneously send 10 different files not exceeding 20 MB. While eFax has the same file limit for faxing, it has an additional feature called Large File Sharing through which users can upload and share up to 3 GB of files with 20 recipients simultaneously. This feature is useful for those who frequently work on projects with distributed teams, since it negates the need to sign up for an FTP solution to exclusively manage online file transfers. Plus, recipients don’t have to be an eFax member to receive files. When a recipient downloads the file, the sender will get an instant email notification alerting them that the file has been viewed.

File format support and integration with file sharing programs: Productivity comes in all formats. eFax supports over 170 standard file types so users can focus on making work happen on the go, rather than wasting time and fighting headaches converting pages to approved formats to send a fax. FAX.PLUS, on the other hand, only supports Adobe PDF files, Microsoft Word documents (DOC and DOCX), Microsoft Excel files (XLS and XLSX), Text files (TXT), and JPG, PNG, TIFF image file formats. While FAX.PLUS shines in collaboration with Slack integration, eFax boosts productivity and profits by bestowing users with the convenience of sending and receiving faxes directly from applications like MS Word, Excel, and PowerPoint; email clients like Outlook and Gmail; or from cloud storage programs like Google Drive (Google Docs), iCloud, and Dropbox. This removes the need to print out the document before faxing it.

Toll-free and local fax numbers: eFax and FAX.PLUS both allow businesses to reinforce a relevant national and regional presence with toll-free and local fax numbers. Users can send faxes from email or mobile devices to different countries, and even get an international fax number to mark themselves as a global leader beyond the United States. But, this feature is excluded from FAX.PLUS’ base plan, meaning a custom fax number comes at a premium price. eFax, however, provides toll-free, international, and local fax number options to all subscription tiers.

Customer support: FAX.PLUS’ customer support is limited to an online help center and email. eFax’s award-winning customer service features multiple support channels — email, phone, live chat, and an online help center. Together, they offer customers unmatched peace of mind with timely and reliable support that’s available 24/7.
