How common is the SPF problem?

Most organizations use a number of different mail service providers - G Suite for business email, MailChimp for marketing emails, Salesforce for customer emails - and each one needs to be added to the organization’s DNS in order to authenticate the emails as genuine using SPF. However, this can quickly breach the 10 DNS lookup limit imposed by SPF.

How does Dynamic SPF work?

Dynamic SPF is an OnDMARC feature that allows you to have more than the normally available number of authorized services using the SPF authentication mechanism. We give you a record that replaces all your mechanisms with a single include that dynamically combines all your authorized services correctly at the point of query. This prevents your authorized traffic from failing SPF validation.
