Emails

Email activity

Email Activity is the operational view for messages sent through Lettermint. Use it to search recent messages, inspect delivery events, view message content, and understand delivery issues.

Search and filter

Use the message list to find messages by sender, recipient, subject, status, project, route, tag, or date range. This is the fastest way to answer "what happened to this email?"

Message details

Open a message to review:

• Current status
• Sender and recipients
• Project, route, and tag
• Delivery event timeline
• Webhook-related events
• Bounce, complaint, suppression, and failure metadata
• Available source, HTML, and plain-text content

Deliverability insights

When available for your plan and message, Lettermint surfaces delivery and spam insights. Use these to spot missing plaintext, large bodies, suspicious links, missing unsubscribe handling, or sender/domain issues.

Team API access

The Team API exposes read-only message endpoints for automation:

• GET /v1/messages
• GET /v1/messages/{messageId}
• GET /v1/messages/{messageId}/events
• GET /v1/messages/{messageId}/source
• GET /v1/messages/{messageId}/html
• GET /v1/messages/{messageId}/text

These endpoints require read:messages.
