 Top SPF Flattening Tools in 2025: Enhance Your Email Security and Deliverability

In a digital world like today, safeguarding an organization's email communications is crucial. Sender Policy Framework or SPF is the key email authentication method to allow outgoing email from only trusted mail servers on your behalf. Hence, dealing with SPF records could be demanding, primarily because you run multiple providers of email services there. The 10 DNS lookup limit in SPF causes problems because they do not let emails into the mailbox or may cause emails to end up as spam. SPF Flattening tools then permit you to reduce the number of DNS records looked up, making your records clean and compliant. 

What Is SPF Flattening? 

SPF records represent entries in the DNS that show which mail servers are allowed to send emails belonging to a domain. When an email is received, the recipient server checks the SPF record to validate the sender. There is, however, a limit on the number of DNS lookups allowed in SPF, i.e., 10; if you exceed this, the SPF will not look up and therefore fail verification, thus leading to potential complications in email delivery. 

If you have many email service providers, one can easily exceed the 10 DNS lookups due to very many "include" in the SPF record. SPF flattening takes care of that by changing the "include" statements into the typical direct addresses translating to outright IP addresses, thus minimizing lookups while ensuring the correct SPF action.

How to find a good SPF flattener:

• When selecting an SPF flattening tool, remember these considerations.

• Price: Make sure the tool should fit into the budget of a person having exactly what is essential.

• DNS Uptime and availability: Reliable delivery of email is ensured by a good tracked uptime commitment of the tool with a web service for DNS.

• Speed: Tool should quickly update SPF records in light of any update in mail infrastructure.

• Error handling: The tool must recognize and correct all SPFErrors automatically.

• Scalability: You ought to be able to grow along with a tool for your job as well.

• Automatic Updates: SPFO automatically updates upon use.
