### Claude connector no longer available

After the last 2 releases (0.3.0 and 0.2.0) I've started having problems with this MCP in Claude:
- could not press update
- could not uninstall
- after manual removeal I can no longer find the connector 🤔 

Just opening this here for now until we figure out why or extract more details

### Update sendEmail schema and implementation to allow changing of sender name

## Description
The MCP doesn't expose the `from.name` parameter, limiting sender customization. This creates a gap with the [Mailtrap Transactional API](https://docs.mailtrap.io/developers/email-sending/transactional), which supports:
```json
{
  "from": {
    "email": "sender@example.com",
    "name": "Sender Name"
  }
}
```

## Request
Expose the `from.name` parameter in the MCP to allow custom sender names for better branding, user recognition, and email deliverability.
