Email History and Reports
Two pages drive all email observability in Blocx:
- Email → History — message-level search.
- Email → Reports — aggregated trends.
For single-message deep dives, use Email → Debug.
Email history
Open Email → History to search every outbound email. Filters:
- Time range — last hour, day, 7 days, 30 days, custom.
- Status — accepted, delivered, deferred, bounced, complained, suppressed.
- From address / To address — exact or wildcard.
- Subject — substring search.
- Domain — your sending domain.
- Tags / metadata — anything you attached at send time.
Click any row to open the timeline: accepted → processed → delivered → opened → clicked → bounced → complained → unsubscribed. Each event is timestamped to the millisecond and includes the receiver-side SMTP response when applicable.
Email debug
Email → Debug is the right page when you have a specific message ID and want every detail:
- Full SMTP transcript with the receiver
- Headers as sent (post-DKIM signing)
- Sending IP used
- DKIM signature and verification result
- The exact reason for any failure
Bounces explained
Each bounce includes the SMTP response code and the recipient server's text. Categories:
| Type | Meaning | What to do |
|---|---|---|
| Hard bounce | Invalid recipient (550 No such user) |
Stop sending. Address added to suppression. |
| Soft bounce | Temporary failure (mailbox full, greylisting, rate limits) | Blocx retries with backoff. After 72 hours of soft bounces we treat as hard. |
| Block | Recipient server rejected for policy (reputation, content, missing auth) | Investigate at Email → Debug; fix and re-send |
| Complaint | Recipient marked as spam | Address added to suppression. Cease all sends. |
Reports
Email → Reports aggregates everything:
- Volume — sends, deliveries, bounces, complaints over time
- Per-domain breakdowns — useful with multiple sending domains
- Per-tag breakdowns — group by your own labels
- Top bouncing recipients — for hygiene
- Engagement — opens and clicks (if tracking enabled)
- Reputation trends — daily delivery, complaint, and bounce rates against industry benchmarks

Tracking opens and clicks
When tracking is enabled, opens are captured via a 1×1 pixel embedded in HTML mail, and clicks are captured via a tracking redirect on each link. Subscribe to the email.opened and email.clicked webhook events at Developer → Webhooks to receive these events in real time. Transactional traffic typically benefits from disabling click tracking — receivers and security tools treat redirect domains with suspicion.
Exporting
Use Export → CSV on either page for a date-ranged export, useful for audits, BI loads, and reconciliation. Larger exports run in the background and are emailed when ready.
