Short answer

Why are my emails bouncing?

Your AI scans your MailerSend activity logs to find specific error codes and delivery failures. It then maps those errors to the exact messages that failed so you can fix your sender reputation or contact lists.

Where every issue lands.

Delivery triage outcomes

The AI categorizes your MailerSend data into these actionable buckets.

CRITICAL

Hard bounce identification

The AI flags permanent failures like invalid addresses. You get a clean list of contacts to remove from your database.

REPUTATION

Spam trap detection

Your agent identifies patterns in bounces that suggest your IP or domain is being flagged. This helps you avoid blacklists.

TECHNICAL

Configuration errors

The AI finds issues with SPF, DKIM, or routing errors. It points out exactly which technical setting is causing the block.

HUMAN

Manual list cleaning

The AI provides the specific email addresses that need manual verification. You decide which contacts to re-engage or prune.

The workflow

What your AI does when the logs arrive.

Instead of you clicking through dashboards, your agent pulls the data and finds the needle in the haystack.

  1. Fetch activity logs

    The agent pulls the latest delivery events and status updates from your MailerSend account.

    list_email_activities

  2. Isolate failed messages

    It filters through the successful sends to find the specific messages that hit a bounce or a soft fail.

    list_sent_messages

  3. Inspect error details

    The AI looks at the deep metadata for a specific failed delivery to see the exact reason provided by the receiving server.

    get_message_info

  4. Summarize root causes

    The agent groups these individual errors into a single report that explains the trend behind your delivery drops.
