As part of MxToolbox's Delivery Center Plus plan, SPF Flattening offers a simple, easy-to-use system to manage your complex SPF configurations, including getting back under the 10 DNS Lookup Limit. If you have more than 10 lookups included in your SPF record, the later lookups will not be executed, leaving some of your legitimate email senders to bounce.
Plus, the more third-party email sources you add to your domain, such as Marketing Automation, CRMs, Customer Support, and Order Fulfillment, you quickly max out of SPF configuration options. This feature removes the SPF limitations by automatically reconstructing your SPF record.
By completing the SPF Flattening integration, you let us ensure that you stay under the 10 DNS Lookup Limit threshold.
