[ Book a Demo → ](/book-a-demo/) [ See Pricing ](/pricing/) What You Get ## A truly unlimited SPF record that always validates Add as many senders as you need. We keep the record flattened, hosted, and valid, so SPF stops being the thing that quietly breaks. SPF is only one leg of authentication, so here it sits beside your [DMARC reporting and alerting](/hosted-dmarc/), and a record that always validates protects your [email deliverability](/email-deliverability/). Prefer that we run it for you? That is part of [Managed Compliance](/managed-compliance/). ### A truly unlimited SPF record SPF normally fails once you pass ten DNS lookups. We use SPF macro technology to lift that ceiling entirely, so you can authorize every sender you will ever add, with no practical limit and nothing to prune. ### Hosted and auto-updated We host the flattened record and keep it current. When a provider changes their sending IPs, your record follows, so a vendor update never quietly breaks your SPF. ### One record, every sender Consolidate all your email services, marketing, support, billing, and internal apps, into a single clean record that actually validates. ### Watched alongside your DMARC SPF is one leg of authentication. Here it sits next to your DMARC reporting and alerting, so a flattening or sender change that affects alignment does not go unnoticed. FAQ ## Common questions What is the SPF 10-lookup limit? SPF includes a rule that mail receivers must stop after ten DNS lookups when evaluating your record. Once you pass that ceiling, SPF fails silently, and adding one more sender is often all it takes to break authentication for legitimate mail. How do you make an SPF record truly unlimited? We use SPF macro technology to resolve your senders at lookup time instead of packing every include into the record. That lifts the ten-lookup ceiling entirely, so you can authorize every sender you will ever add, with no practical limit and nothing to prune. Does the record update automatically when a provider changes IPs? Yes. We host the flattened record and keep it current. When a provider changes their sending IPs, your record follows automatically, so a vendor update never quietly breaks your SPF. Can I consolidate all my senders into one record? Yes. You can bring your email services, marketing, support, billing, and internal apps into a single clean record that validates, watched alongside your DMARC reporting and alerting. Is hosted SPF flattening a paid feature? Yes. Hosted SPF flattening is part of DMARC Report paid plans. You can book a demo to see it on your own domain, or review pricing for the plans that include it. ## Fix SPF once and stop worrying about it Flatten and host your SPF record with DMARC Report, and keep it valid as your senders change.
