How SendPup works

One little DNS change. A much clearer picture.

Point reports to Scout

Add one reporting address to your DMARC record. Your email keeps flowing exactly as it does today.

Meet every sender

Daily aggregate reports become a clean map of Google, SendGrid, Mailchimp, forgotten tools, and suspicious sources.

Protect when ready

Follow plain-language fixes, then move from monitoring to quarantine or reject only when your real senders are ready.

Deliberately low access

SendPup watches the envelope, not the letter.

SendPup receives aggregate authentication counts from mail providers. It does not need an inbox connection, message body, subscriber list, or email-address verification.
