SPF Flattening: Resolve SPF PermErrors

What is SPF Permerror? 

When the recipient mailbox provider cannot verify an SPF record, an SPF permerror result is returned to the sender if the sending domain has DMARC monitoring enabled. When your SPF record generates too many DNS lookups and exceeds the 10 DNS lookup limit, it is rendered invalid, and in such cases, this permerror result is returned to the sending domain. PowerSPF helps you mitigate SPF permerror by instantly flattening your SPF record.

How to fix SPF Permerror?

To Fix SPF Permerror (SPF permanent error) for your emails, you need to deploy an SPF flattening solution. 

What is Automated SPF Flattening?

With an automatic SPF flattening tool, you will experience the following benefits: 

• Record shortened to a single include 
• Staying under the 10 DNS lookup limit at all times 
• Fixed SPF Permerror 
• Record length limit consistently maintained 
• Staying on top of any IP address updates 
• Use an automated SPF record flattening tool

Why Manual SPF Record 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 emails 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. If you exceed the 10 DNS lookup limits you will get SPF permerror or SPF temperror.
