Best SPF Flattening Recommendation

If your SPF record includes too many DNS lookups, it can break — and that harms deliverability. Flattening your SPF record means converting all include: statements into direct IP addresses to stay under the 10-lookup limit.

Best tool?

We recommend SPF-Record.com or EasyDMARC’s SPF Flattening tool — both let you flatten your SPF with a single click.

Pro tip:

• Re-check your SPF record every time you update your email service providers.
• After flattening, test your DNS setup using tools like MXToolbox or Mail-Tester.
