This article explains step by step how to use Track Delivery in cPanel to view a message’s route, delivery status, reasons for failure, and how to interpret the results.

7. Best Practices for Deliverability
1) Access Track Delivery
- Log in to cPanel.
- Open the Email → Track Delivery section.
- (Optional) Make sure the feature is enabled by your hosting provider. If you don’t see results, contact support.
Note: Track Delivery displays up to ~250 recent messages from the mail server database. If the server uses a third-party filter/relay, some results may be limited.
2) Search and Filter
- In the Recipient Email (optional) field, enter the recipient’s address you want to check (e.g., [email protected]).
- Click Run Report.
- Use the quick filters:
- Show All – displays all events.
- Show Blocked & Failed – displays only blocked/failed messages.
Tip: Clear the address from the field and run the report again to return to all messages. Note that the trace diagram may remain for the last searched address.
3) Delivery Report: columns and their meaning
| Column | Description | How to use it |
|---|---|---|
| Event | Status icon (successful, failed, deferred, in progress). | The first sign if delivery succeeded or not. |
| From Address | Sender’s address. | Check if the message was sent from the correct address. |
| Sender | The cPanel user who sent it. | Useful for accounts with multiple domains/mailboxes. |
| Sent Time | Date/time of sending (browser’s timezone). | Correlate with complaints or your own tests. |
| Spam Score | Score generated by spam filters. | If high, optimize content/DNS/SPF/DKIM. |
| Recipient | Recipient’s address. | Confirm it is spelled correctly. |
| Result | Summary of delivery result (including reason for failure). | Starting point for troubleshooting. |
| Delivery Host / IP | Server/IP where delivery was attempted. | Check if it’s correct & responsive. |
| Authentication | Authentication method (if applicable). | Confirm the message was authorized. |
| Router / Transport | Internal MTA stages (Exim). | Advanced diagnostics for admins. |
You can customize the displayed columns (hide/show fields) from the table settings to view only the relevant information.
4) Email Address Trace (message route)
The Email Address Trace diagram visually shows the email’s path: source server, filters, destination server. Use it to quickly identify where the block occurs (e.g., local antispam filter or recipient’s server).
5) Event Icons (statuses)
- Success – message delivered successfully.
- Deferred – delivery was postponed (recipient server responded temporarily).
- In-Progress – delivery still in progress.
- Failure / Rejected – delivery failed (e.g., nonexistent mailbox, server policy, block).
- Filtered – filtered by antispam/other rule.
6) Troubleshooting: common errors & fixes
| Symptom / Message | Probable Cause | Recommended Solution |
|---|---|---|
550 No such user | Recipient does not exist or misspelled. | Check the address; ask the recipient to confirm. |
550 Access denied / Policy rejection | Strict policies on recipient’s server. | Enable and align SPF/DKIM/DMARC; request whitelist from recipient. |
421/451 Temporary failure (Deferred) | Temporary issues on recipient’s server / rate limiting. | Retry automatically; if persists >24h, contact the recipient. |
| High spam score | Content, format, attachments, IP/domain reputation. | Optimize content, check RBL lists, configure SPF/DKIM/DMARC. |
| Delivered but lands in Spam | Missing/misconfigured signatures, aggressive promo content. | Sign with DKIM, correct SPF/DMARC policies, clean up template. |
7) Best Practices for Deliverability
- Properly configure SPF, DKIM, and DMARC for your domain.
- Use a clear Subject and avoid aggressive marketing tactics.
- Include an unsubscribe link in campaigns.
- Avoid large attachments and executable files.
- Monitor IP/domain reputation and remove invalid addresses from lists.
