Email Deliverability Solved
Automated SPF Record Flattening and Continuous Management. Never exceed the critical **10-Lookup Limit** again and ensure your emails land in the inbox.
Per **RFC 7208**, your SPF record is limited to **10 DNS lookups**. Every email service, CRM, or marketing tool you add increases this count. Exceeding the limit means your emails fail SPF authentication, leading to **rejection and spam filtering**. SPF Zone solves this permanently.
Immediately check any domain to see your current SPF lookup count, identifying which records are pushing you over the limit.
We collapse all your `include` and `a` mechanisms into a single, compact record, guaranteeing you always stay at **1 lookup**.
Host your flattened record with us via a simple `include:spf.zone` entry. We monitor and update it in real-time as your services change.
Use our intuitive user interface to quickly add or remove email services without having to touch raw DNS records.
