Common Questions
Frequently Asked Questions
What is SPF flattening?
SPF flattening resolves all nested include mechanisms in your SPF record into a flat list of IP addresses. This reduces DNS lookups from 10+ to just 2-3, keeping you within the RFC 7208 limit of 10 DNS lookups per SPF evaluation. AutoSPF automates this process and rescans every 15 minutes.
What is the SPF 10-DNS-lookup limit?
RFC 7208 limits SPF evaluation to 10 DNS lookups per query. Each include, a, mx, and redirect mechanism counts as one lookup. Most businesses using 5+ email services (Google Workspace, Salesforce, Mailchimp, etc.) exceed this limit, causing SPF to return a permerror and emails to fail authentication.
How does AutoSPF work?
AutoSPF replaces your complex SPF record with a single managed include that points to our infrastructure. We continuously resolve all your sending services into optimized IP lists, served through Cloudflare DNS with 99.99% uptime. Setup takes 60 seconds: copy, paste, replace one DNS record.
How long does AutoSPF take to set up?
60 seconds or less. Add your domain, copy the generated SPF record, paste it into your DNS provider, and you are done. If setup takes longer than 60 seconds, your first year is free — that is our guarantee.
Does AutoSPF support SPF macros?
Yes. AutoSPF is one of the only SPF management providers offering macro-based SPF. Macros allow truly unlimited includes with just 1-2 DNS lookups, plus IP obfuscation so competitors cannot see your authorized senders. Available on Premium ($97/mo) and Enterprise ($387/mo) plans.
Does AutoSPF include DMARC reporting?
No — AutoSPF is a dedicated SPF management tool with enterprise-grade SLAs specifically for serving your SPF record. For DMARC reporting, we offer DMARC Report (dmarcreport.com), a separate purpose-built product. This separation ensures our SPF uptime SLA is never compromised by reporting workloads.

What Our Customers Say
"Helped us go beyond capacity"
AutoSPF did exactly as described, it helped us get past our 10 lookup limit. Afterwards, we hit another limit regarding overall capacity and when contacted, they quickly provided us with a new solution to eliminate capacity issues entirely going forward, so now we can add as many SPF records as needed. They also provided us with a personalized support video explaining their new method in its entirety using our instance as the example.
