Dynamic SPF

An SPF record is like an instructions booklet for email servers. By looking up your record, the receiving server distinguishes between authorized and unauthorized IP addresses, and rejects fake emails. Dynamic SPF resolves all that with ease.

SPF Records Have One Major Problem

  • Your SPF record has a limit of 10 DNS Lookups. Every time you add a new ‘mechanism’ in your record, you require a new lookup. You need to use mechanisms to add new IP addresses.

  • If your organization relies on several third-party vendors to send email from your domain, that’s more IPs to authorize. And the more IPs you want to authorize, the more mechanisms you need. Starting to see the problem here?

  • Once your SPF record exceeds the 10 DNS Lookup limitation, you receive a ‘permerror’ result. This means the email receiver considers your SPF record invalid and automatically blocks it.

You could be having email delivery issues without even knowing it.
As the domain owner, you need to fix this issue immediately. Our Dynamic SPF is the quickest resolution.

Why SPF Flattening Is Not A Solution

SPF flattening isn’t a one-time deal. If your email service provider changes their infrastructure, you’re going to have to change your SPF records accordingly. Every single time.

The more third-party vendors you have sending email from your domain, the more email providers you all use. If any one of them changes, you have to change your SPF record all over again.
