Symptoms#
- Messages landing in spam despite previously good placement
- Bounces mentioning policy, authentication, or reputation
- Provider dashboards showing a drop in reputation or authentication pass rate
Diagnosis steps#
- Confirm the configuration is live: query DNS from an external resolver and check the sending platform's settings page.
- Send to a seed mailbox and read the full headers, especially Authentication-Results.
- Compare the domains in From, Return-Path, and DKIM d= for alignment.
- Check provider dashboards (Google Postmaster Tools, Microsoft SNDS) for reputation and error rates.
- Review recent changes: new vendors, DNS edits, list imports, volume spikes.
Likely causes#
- Building elaborate folder taxonomies nobody maintains.
- Checking email on every notification.
Fix and re-verify#
- Process in batches two or three times a day instead of continuously.
- For each message decide: delete, archive, reply in two minutes, defer with a snooze, or delegate.
- Use labels for state (waiting-on, to-read) rather than topic.
- Automate the obvious: newsletters to a digest, notifications to a folder.
- Review snoozed items every morning.
