Free and private. We only read public DNS records.

How SendPup works

One little DNS change. A much clearer picture.

01

Point reports to Scout

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

02

Meet every sender

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

03

Protect when ready

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

Sender discovery

Your mail trail, translated.

DMARC reports are dense XML files. SendPup turns them into a short list of recognizable services and the one thing each needs.

  • Aligned SPF and DKIM status
  • Message volume by source
  • Unknown-sender alerts
  • Weekly plain-English digest

Deliberately low access

SendPup watches the envelope—not the letter.

We receive aggregate authentication counts from mail providers. No inbox connection, message body, subscriber list, or email-address verification is required.

One uncomplicated plan

Start free. Bring Scout home when the reports matter.
