Grouped by receiving MX infrastructureRemote acceptance means the receiving server accepted the message. Provider acceptance means an upstream relay accepted it. Neither establishes inbox placement. Counts describe local observations, not provider complaint rates.
Read a controlled test message
Send a test through your normal sending route to an inbox you control. Open the received message’s original headers and paste them below. The app reads receiver-reported SPF, DKIM and DMARC; it does not send mail or retain the body.
Uploaded headers are operator-supplied evidence. Their origin is not independently verified, and inbox placement stays unknown.
