# Send Email

Send an Email message

### Description <a href="#prop-title" id="prop-title"></a>

Send an email using the parameters.

### Properties

#### Connection String

Add a query string with the connection options for your mail provider.

* host - the host of the mail server e.g. smtp.gmail.com for Gmail
* port - the port number. The default is 25. Others include 465, 2255
* user - the connection username
* password - the connection password

```
// example connection string
host=smtp.mailtrap.io&port=34&user=username&password=pass
```

#### Additional Connection Settings

* tsl\_rejectUnauthorized - Used to reject a TLS connection if unauthorized. Default is false
* ignoretls - if this is *true* and *secure* is false then TLS is not used even if the server supports STARTTLS extension *(from node mailer docs)*
* requiretls - if this is *true* and *secure* is false then Nodemailer tries to use STARTTLS even if the server does not advertise support for it. If the connection can not be encrypted then message is not sent *(from node mailer docs)*
* secure - if *true* the connection will use TLS when connecting to server. If *false* (the default) then TLS is used if server supports the STARTTLS extension. In most cases set this value to *true* if you are connecting to port 465. For port 587 or 25 keep it *false (from node mailer docs)*
