FAQ: Best Cheap Online Fax Service
Q: Can I send a fax from my email?
A: Yes, most online fax services, including FAX.PLUS, SRFax, and MetroFax, offer an "email-to-fax" feature. Once you register your email address, you can send a fax by addressing an email to the recipient's fax number followed by the service's domain (e.g., [email protected]). The email subject becomes the cover page subject, and any attachments are sent as the fax document.
Q: Do I need a physical fax machine to use an online fax service?
A: No, you do not need any physical hardware. An online fax service allows you to send and receive faxes entirely through a web browser, a dedicated desktop application, or a mobile app on your smartphone. All you need is an internet connection.
Q: Is it safe to send sensitive documents with an online fax service?
A: Reputable online fax services use strong encryption (like 256-bit SSL) to secure your documents during transmission. This is often more secure than a traditional fax machine, where documents can sit exposed on a receiving tray. Services like FaxZen also offer features like automatic document deletion after 24 hours to further enhance data privacy.
Q: Can I keep my existing fax number?
A: Many subscription-based online fax services, such as MetroFax and FAX.PLUS, offer number porting. This allows you to transfer your existing fax number to their service, so you don't have to update your contact information with clients and partners. There may be a one-time fee or it may be included in higher-tier plans.
Q: What is the cheapest way to send a one-time fax?
A: For a single, small fax (3 pages or fewer), a free service like GotFreeFax is the cheapest option. For a slightly larger one-time fax or if you need more robust delivery confirmation, a pay-as-you-go service like FaxZen offers the best value without requiring a subscription.
