What Is the Best Online Fax?
How to choose the best online fax service
Are you still trying to decide which digital fax vendor to select? Make sure you’re getting the service that will provide the most value.
A cost-effective online fax service is not only affordable but also offers the following:
Positive third-party reviews
Before paying for anything, always check third-party reviews or see which companies the internet fax service has worked with previously. If you want to do a deep dive, you can even look up the service’s developer and publisher and do a background check of each to ensure credibility.
Choosing a credible fax provider is a must, especially if you transmit sensitive documents in high volumes. If you are not careful, you could put your business at risk and face the possibility of paying hefty fines.
Responsive customer support
Another thing to consider for an online fax service is customer service support. Is the support 24/7? Is there customer support available even for free plans? As internet faxing can be confusing for a first-timer, you’ll want assistance at any given time.
It is also best to check the online fax provider’s communication channels. Live chat support is better than email because it can provide you with an immediate response.
Flexible pricing plans
Most internet fax services provide tiered pricing that caters to a particular user or market. These pricing options vary widely per service provider, so you’ll want to consider which plan best suits your budget.
How often do you plan to fax documents? On average, how many pages would you need to send or receive in a month? Besides this, you also need to ensure that your fax service provider allows cancellations and upgrades at no extra charge.
Secure fax transmissions
Securing your documents using end-to-end encryption prevents unwanted access and fraudulent transactions. If a fax provider offers 256-bit encryption, you can guarantee that it has the necessary measures to safeguard you against malware, phishing, and other cyber threats.
Another thing to consider is whether the fax service supports two-factor authentication, which can help prevent unauthorized takeovers in case your password gets stolen.
Compatibility with multiple apps and devices
Many businesses rely on faxes for critical communications. If your fax service can integrate seamlessly with your existing apps, it’ll be easier for you to build a cohesive workspace infrastructure. There’s also no need to hire a developer to integrate faxing into your cloud-based CRM platform.
If your fax service supports integration via API or Zapier, you won’t have to spend hours figuring out how to make two systems work together. You can connect apps without writing a single line of code.
Transparent cancellation policy
Not all fax providers offer a straightforward process for subscription cancellation. Before signing up, you must ensure that you’ve thoroughly read the fine print. Look out for hidden charges. If you are not careful, you could end up paying beyond what you initially expected.
By carefully evaluating a provider’s policy, you can save yourself the hassle of going through a lengthy refund process. You can also avoid paying for unnecessary recurring charges.
Simple signup process
A good fax service provider will make signing up as straightforward as possible. There should be clear instructions on how to sign up. Plus, it would be best if the service supports single sign-on (SSO), which allows you to sign up and log in using your existing SSO credentials.
Not only does it help speed up the signup process, but it also reduces password fatigue. The service should also make it easier for you to sign up using your existing Microsoft, Twitter, or Google account.
