One focused workspace

Sent does not mean
delivered to the inbox.

SenderGlow separates placement evidence, technical quality, and controlled sender health—so you can see what happened and what to do next instead of trusting one misleading score.

01

Inbox placement

Which folder did the
message actually reach?

Go beyond a single “delivered” status. SenderGlow reports observed Inbox, Spam, and missing results separately across the connected measurement network.

  • Observation in real provider accounts
  • Correlation without reading message content
  • Reporting with time and network scope

02

Technical quality

Investigate the cause,
not only the symptom.

SPF, DKIM, DMARC, MIME structure, and spam signals are evaluated independently. Placement evidence is never confused with a technical quality score.

  • A unique, expiring recipient for every test
  • Authentication and message structure
  • A clear, actionable next step

MAIL QUALITYEvidence-based score

03

Controlled sender health

Start slowly.
Progress deliberately.

For authorized mailboxes, define the starting volume, daily increase, upper limit, sending window, and controlled reply rate.

  • Low volume distributed across the day
  • Inbox checks and configured spam rescue
  • User control that can be paused at any time
