## Description

Connect your MailerSend account to any AI agent to automate your transactional messaging and domain management. This Connector enables your agent to send single or bulk emails, monitor domain verification, and track email activity directly from natural language interfaces. You can now let your AI agent handle the heavy lifting of your email infrastructure. Instead of jumping between a dashboard to check if a domain is verified or hunting through logs to see if a message actually landed, you can just ask your agent to do it. You can send out a batch of 500 welcome emails, check the status of a specific recipient, or pull the latest activity logs for a sender domain to see how people are interacting with your content. It takes the manual work out of managing your transactional messaging flow. You'll find this is a huge time-saver when you're trying to keep your communication consistent across different platforms. When you connect it through the Vinkius catalog, it becomes a core part of how your agent interacts with your mailer account, making your dev and ops workflows a lot less fragmented. You can quickly check if your DNS records are correct or if a specific domain is ready for use without having to navigate through complex settings pages. It gives you a direct line of sight into your delivery performance, allowing you to stay on top of your outgoing mail without the usual friction of manual data entry or constant tab switching.

```
I've sent the welcome email to **new_user@example.com**.

Your agent has handed this off to MailerSend for delivery.
```

**Prompt:** 
```
Check if our primary domain is verified and show me the DNS status.
```

**Response:** 
```
I've checked the status for your primary domain. Here is what I found:

| Domain | Status | DNS Verified |
| :--- | :--- | :--- |
| mail.example.com | **Verified** | Yes |
| alerts.example.io | **Unverified** | No |

Would you like me to trigger a verification check for the unverified domain?
```

**Prompt:** 
```
Show me the activity logs for the last 50 emails sent to our marketing domain.
```

**Response:** 
```
I've pulled the latest activity for your marketing domain. Here are the most recent interactions:

- **Opened**: 12 interactions in the last hour.
- **Clicked**: 4 interactions in the last hour.
- **Delivered**: 48 messages successfully reached the inbox.

Most activity is coming from the `newsletter_v3` campaign.

## Capabilities

### Send single transactional emails
Dispatch a single message using a template or raw HTML content.

Send up to 500 emails in one request for high-volume messaging.

## Use Cases

### Verifying DNS for Production
A developer needs to verify a domain's DNS settings before a production launch. They ask their agent to check the status and confirm it's ready for high-deliverability mail.

### Troubleshooting Failed Deliveries
An operations manager wants to see why a specific batch of messages failed to deliver. They ask their agent to pull the full metadata using get_sent_message_details.

### Sending Bulk Signup Alerts
A marketing engineer needs to send a bulk update to 400 new users who just signed up. They use send_bulk_transactional_emails to get the job done in one command.

### Auditing Recipient Data
A support person wants to list all recipients in the database to find a specific user's contact info. They ask the agent to query the list and find the right person.
