Short answer

How can I use my AI to check email and SMS codes?

Your agent uses Mailosaur to locate specific messages in your virtual inboxes and read their contents. This lets you confirm that your system is sending the right data to the right places. You'll see exactly how the agent finds and inspects these messages below.

Verification outcomes

Where your data lands.

The AI processes incoming messages and organizes the results based on what you need to confirm.

SUCCESS

Verified message content

The AI finds the exact email or SMS you're looking for and extracts the text. You get the specific data points needed to confirm a successful transaction.

FAILURE

Missing message alerts

If the expected message never arrives in the virtual inbox, the AI reports the absence. This helps you catch broken delivery flows immediately.

HUMAN

Manual review needed

If the AI finds a message but the content doesn't match your expected patterns, it flags it for you. You decide if the message is valid or a bug.

LOGS

Inbox audit trail

The AI can summarize the history of messages in a specific inbox. You get a clear view of all recent transactional activity.

The workflow

What your AI does when the message arrives.

The AI acts as a bridge between your Mailosaur inboxes and your chat interface.

  1. Locate the message

    The agent scans your Mailosaur inboxes to find the specific email or SMS sent to a virtual address.

  2. Read the content

  3. Extract data

    The agent parses the message body to find specific values like OTP codes, links, or user IDs.
