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.
Dynamic SPF overcomes the 10 lookup limit by enabling you to use a single dynamic include statement to combine all authorized services correctly at the point of query. This prevents your authorized traffic from failing SPF validation, regardless of how many sending services you use.
Red Sift’s managed SPF solution doesn’t require the use of macros making it fully compatible with global email systems, whilst removing the known SPF entry restrictions.
The majority of legacy email infrastructures do not support SPF macros, causing catastrophic deliverability issues. So, Dynamic SPF was developed as a future-proof solution.
Does not rely on a macro-based approach that many other vendors use, meaning that all legacy email structures, gateways, and receivers support it. Where others claim reliability, we guarantee it.
A dynamic include statement monitors and updates IPs continuously. We dynamically flatten and compact SPF because it is simpler, virtually unlimited, and works with all devices.
Monitors and heals syntax errors using ‘last known good’ values. If errors are encountered, they are skipped and emails continue to flow. When errors are fixed, Dynamic SPF automatically incorporates the updated values.
Dynamic SPF removes the need for you to have the technical knowledge required to write complex SPF records and manually edit your DNS. Simply configure your required services from within the OnDMARC app.
The clue is in the name, Dynamic SPF automatically ensures every record for all 3rd party services is up to date at point of query, there’s no static code to become outdated or obsolete. Dynamic SPF works with any existing mail service or ISP.
Our single dynamic include statement combines all authorized services correctly at the point of query and prevents your authorized traffic from failing SPF validation, regardless of how many sending services you use.
Every day, Dynamic SPF effortlessly authenticates millions of emails for huge global organizations. It does not rely on a macro-based approach that many other vendors use, meaning that all legacy email structures, gateways, and receivers support it.
