Who this tool is for

Business owners, developers, and site admins whose domain sends transactional or marketing email and who need to understand why messages are landing in spam or failing to deliver.

What this tool checks

SPF record presence, syntax, and whether it covers all sending sources correctly
DKIM configuration and whether the signing key aligns with the sending domain
DMARC policy — whether it exists, what action it specifies, and whether reporting is configured
MX record quality and whether the mail routing setup introduces unnecessary delivery risk

What you will get

A plain-language deliverability health summary with a pass, warning, or fail status for each check
A prioritised fix list starting with the changes that will have the most impact on deliverability
An explanation of why each flagged issue matters and what spam filters and receiving servers look for
A clear path toward stable, consistent mail delivery across all sending scenarios
