How to debug email delivery failures with your AI

Connect SparkPost to your AI client to turn raw bounce data into actionable fixes. Once connected, your agent handles the heavy lifting of pattern recognition.

Short answer

Why are my emails failing to reach recipients?

Your AI pulls specific bounce logs and deliverability stats from SparkPost to find the root cause. It looks for patterns in error codes, domain reputation, or sender authentication issues. You get a clear breakdown of what went wrong and how to fix it.

Where every issue lands.

The outcomes of your analysis

The AI sorts the data into these specific categories to help you move faster.

CRITICAL

Hard bounce patterns

The AI identifies clusters of invalid addresses or blocked domains. You'll see exactly which segments are causing the most noise.

REPUTATION

Deliverability health

It checks your sender reputation and engagement metrics. This tells you if your IP or domain is being throttled.

TECHNICAL

Auth and config errors

The agent flags SPF, DKIM, or DMARC failures. This points to setup issues rather than recipient problems.

HUMAN

Manual fixes needed

The AI flags issues it can't fix, like cleaning your list or updating DNS records. These are the tasks you need to handle personally.

The workflow

What your AI does when the data arrives.

The AI moves from raw data collection to specific troubleshooting steps.

  1. Gathering bounce data

    The agent pulls the latest error logs and bounce reasons from your account.

  2. Checking health metrics

    It examines your overall delivery success rates and reputation scores.

    get_deliverability_metrics

  3. Identifying patterns

    The AI compares bounce types against your recent sending volume to find anomalies.

FAQ

How this task behaves

  • 01

    Can the AI fix my DNS records?

    No. The AI can identify that your SPF or DKIM is failing, but you have to log in to your domain provider to fix it.

  • 02

    Can the AI delete bounced email addresses for me?

    No. The AI only reads the data from SparkPost. It cannot modify your recipient lists or delete any records.

  • 03

    Does the AI see my actual email content?

    No. It only accesses the bounce events and deliverability metrics provided by the tools.

  • 04

    Can I use this with Claude or Cursor?

    Yes. Any MCP-compatible client works once you've connected the SparkPost MCP through Vinkius.

  • 05

    How often does the AI pull new data?

    The AI pulls data in real time whenever you ask it a question that requires those specific tools.
