Logs

Logs

Every email has a per-email event timeline — sent, delivered, bounced, complained, opened, clicked, delivery_delayed — in the dashboard, via GET /emails/:id, and forwarded to webhooks.

Every email you send through the API gets a per-email event timeline. As the message moves through MailBlastr’s sending infrastructure and reaches the recipient, MailBlastr records each event against the email’s id, giving you a complete delivery and engagement history.

Event types

EventMeaning
sentMailBlastr accepted the email for delivery.
deliveredThe receiving mail server confirmed it accepted the message.
bouncedThe message could not be delivered (e.g. unknown mailbox or a hard rejection).
complainedThe recipient marked the message as spam.
openedThe recipient’s mail client loaded the tracking pixel (requires open tracking).
clickedThe recipient clicked a tracked link (requires click tracking).
delivery_delayedDelivery was temporarily deferred and is being retried.

Where to find the timeline

  • In the dashboard — open an email to see its full event timeline.
  • Via the API — fetch the email with `GET /emails/:id` to read its current status and events.
  • Via webhooks — each event is also forwarded to your configured webhook endpoints in real time. See Webhooks.
Open and click events only appear when the sending domain has the corresponding tracking toggle enabled. See Open and click tracking.

API request logs

Separately from the per-email timeline, MailBlastr records a log of the API requests your keys make. This is useful for monitoring activity and troubleshooting integration issues. Each log entry shows:

  • Endpoint — the API endpoint called (e.g. /domains, /api-keys, /contacts).
  • Status — the HTTP response status code (200, 201, etc.).
  • Method — the HTTP method used (GET, POST, DELETE, etc.).
  • Created — when the request was made (shown as relative time).

Searching and filtering

Use the search bar to find a specific request. You can filter the list by response status to surface issues quickly:

  • All Statuses — view all logs.
  • Successes — only successful requests (2xx).
  • Errors — only failed requests (4xx and 5xx).
  • Specific codes — select one or more exact status codes (e.g. 200, 201, 403, 429); you can combine codes into a custom filter.

You can also narrow by Date range (e.g. last 15 days), User Agent (the client used), and API Key.

Log details

Open any log entry to see the full request body, HTTP method, endpoint, and User-Agent, alongside the complete response body, status code, and timestamp. For supported error types, a Help me fix action opens troubleshooting guidance with the raw response, step-by-step instructions, relevant documentation links, and contextual data such as your current rate limits and verified domains.

Exporting data

Admins can export team data as CSV for Emails, Campaigns, Contacts, Segments, Domains, Logs, and API keys. Apply filters to your data, click Export, and confirm. Exports of 1,000 items or fewer download immediately; larger exports are emailed as a download link.

Exports are limited to admin users. All admins can access a created export for 7 days, after which it is marked Expired. Every team member can see the list of exports, but only admins can download the data.
