Free yourself from SPF limits
proSPF dynamically flattens your SPF record, leaving you in complete control
Fast
proSPF’s DNS servers are hosted on Microsoft Azure and Google Cloud Platform – so they’re geographically dispersed and run a high performance version of BIND9 from the ISC.
Up-to-date
We read the value of prospf.yourdomain.com every hour, run it through the proSPF flattening engine, and immediately update your SPF record on our servers.
Trusted
We run a high performance, highly secure version of BIND9 from the ISC, with low TTL values for your SPF record. So any changes you make will be picked up quickly.
