We are committed to protecting the privacy of our customers and keeping fax spam out of everyone’s email inbox. Please follow these steps if you receive an unsolicited fax.

For security reasons, SPF (Sender Policy Framework) must be enabled to send faxes by email and your SPF cannot be set to Neutral, or your fax will fail. If you received an SPF error, this means your DNS server is missing a valid SPF record. Contact your email administrator to add an SPF record to your DNS. Or, if you are the admin, you can generate an SPF record here and follow this setup guide. To check your SPF record, click here.

Note: You can still send faxes via your account online or our mobile app, regardless of SPF status.
