For each service we considered, we sent three test faxes to a virtual Kall8 phone number: a one-page PDF, a one-page DOC, and a 25-page PDF. We avoided services with confusing price tiers, sign-up fees, or extra charges for features that a freelancer or small-business owner would regularly need to access. For professional use, we focused on options that had straightforward subscription pricing.
Free faxing or low fees: For occasional faxing, we sought out the services that let you fax for free or that charged no more than a one-time $1 to $2 fee to send a long document.
