SPF Flattening Tool

Core Coding® SPF Flattening optimizes your SPF record by simplifying and restructuring it. If your SPF record exceeds 10 DNS lookups, additional lookups won't be processed, potentially causing legitimate emails to fail.

Core Coding® SPF Flattening Tool will:

• Analyze all Verified Email Sources and discover IP addresses in your current SPF record.
• Scan every email sender listed to build a comprehensive list of necessary IP ranges.
• Eliminates duplicate entries by merging overlapping IP ranges.
• Generates an SPF record that fully complies and includes all Verified Senders.
