# Filtering and Troubleshooting

Learn how to troubleshoot email delivery issues and locate specific messages in your activity logs.

***

## Filtering Logs

In the **Activity Logs** view, combine multiple filters to isolate messages:

* **Recipient**: Search by full email or domain (e.g. `*@gmail.com`).
* **Status**: Filter by `Delivered`, `Bounced`, `Complained`, or `Failed`.
* **Date Range**: Today, Last 7 Days, Last 30 Days, or a Custom Date Range.
* **Tag**: Filter by metadata tags passed during the API send request.

***

## Troubleshooting Common Issues

### Issue: "Email marked as delivered, but user cannot find it"

1. **Check Spam / Junk folder**: Even with verified DKIM and SPF, aggressive recipient filters or new domain age may route emails to Junk.
2. **Gmail Tabs**: Check the "Promotions" or "Updates" tab in Gmail.
3. **Corporate Firewalls**: Security software like Mimecast or Proofpoint may quarantine inbound emails pending admin approval.

### Issue: "Domain Mismatch (403)"

Ensure the `from` address in your API request matches a domain with status **Verified** in your Mailofly dashboard.
