# Custom SMTP Email Integration with Novu

> Connect Custom SMTP to Novu to send email notifications through notification workflows. Step-by-step credential setup.

You can use a Custom SMTP provider like [Nodemailer](https://nodemailer.com/about/) to send transactional emails through your custom SMTP server to your customers using the Novu Platform with a single API.

## Getting Started

To use the Custom SMTP provider in the email channel, you will need to have your personal SMTP server configured and add `host`, `port`, `user`, and `password` to the Custom SMTP integration on the Novu platform.

You can also provide value **`true`** for the `secure` field if you want the connection to be secure, and if not, leave it empty.

### DKIM (DomainKeys Identified Mail)

DKIM options can be used in order to sign messages sent using Custom SMTP with DKIM keys.

Those options are:

* `DKIM Domain`
* `DKIM Private Key`
* `DKIM Key Selector`

## Creating a Custom SMTP integration with Novu

* Visit the [Integrations](https://dashboard.novu.co/integrations?utm_campaign=docs-customsmtp) page on Novu.
* Click on Add a Provider.
* Select Custom SMTP service.
* Enter your SMTP credentials
  * `host`
  * `port`
  * `username`
  * `password`
  * `secure` (on demand)
  * And `DKIM` options if you want to sign messages with *DKIM*
* Fill in the `From email address` field using the authenticated email from the previous step.
* Click on the `Disabled` button and mark it as `Active`.
* Click on the **Update** button.
* You should now be able to send notifications using Custom SMTP in Novu.
