## Prerequisites

- A [Github](https://github.com) account
- An [AWS](https://aws.amazon.com) account

If you have any questions join [#self-host](https://discord.gg/gbsvjb9MqV) on discord.

## Step 1: Environment variables

Unsend depends on AWS ses to send emails and SNS to receive email status. Along with that it also depends on Postgres as a database and Redis for queue. Copy the `.env.selfhost.example` file to `.env` and fill in the values.

<Steps>
  <Step title="AWS credentials">
  tl;dr: Login to your AWS console and create a new user with programmatic access. Attach the `AmazonSNSFullAccess` and `AmazonSESFullAccess` policies to the user. Then create a new access key for the user.

Add the following environment variables.

    ```env
    AWS_ACCESS_KEY_ID=<access-key-id>
    AWS_SECRET_ACCESS_KEY=<secret-access-key>
    ```

<Tip>
  Follow this for detailed steps: [Create AWS
  credentials](/get-started/create-aws-credentials)
</Tip>

  </Step>
  <Step title="Github app credentials for login">
  Usend uses github authentication for login.

Use this link to [create an github app](https://docs.github.com/en/apps/creating-github-apps/about-creating-github-apps/about-creating-github-apps)

Callback URL : `https://<your-unsend-instance>/api/auth/callback/github`

Add the following environment variables.

```env
GITHUB_ID="<your-github-client-id>"
GITHUB_SECRET="<your-github-client-secret>"
```

  <Info>If you want email/password login, please help us out with the [code](https://github.com/unsend-dev/unsend) </Info>  
  </Step>
  <Step title="Database & Redis">
  Unsend uses Postgres as a database and Redis as a queue. You need to create a new database and add the following environment variables.

If you're using docker-compose or our railway template, it's all automatically done for you.

```env
DATABASE_URL="postgres://<username>:<password>@<host>:<port>/<database-name>"
REDIS_URL="redis://<username>:<password>@<host>:<port>"
```

  </Step>
  <Step title="Next auth url and secret">
  Url is the app url you're going to use and secret is random string. You can generate a random secret using this command.

```sh
openssl rand -base64 32
```

Add the following environment variables.

```env
  NEXTAUTH_URL="https://<your-unsend-instance>"
  NEXTAUTH_SECRET="<your-unsend-secret>"
```

  </Step>
</Steps>

## Step 2: Setting up the app

You can use any platforms that supports docker. You can also use the railway template. In this example I'll be using railway. If you have any questions drop in the [discord channel](https://discord.gg/gbsvjb9MqV) and i'll try to help you out

### Docker

Follow this guide to setup your docker instance: [Set up docker](/get-started/set-up-docker)

[![Docker image](https://img.shields.io/badge/dockerhub-images-important.svg?logo=Docker)](https://hub.docker.com/r/unsend/unsend)

### Railway

This option is very easy. Click on the below button and click "Deploy now". Add a custom domain etc.

Updating image is easy, click on the 3 dots and redeploy. This will pull the latest image.

[![Deploy on Railway](https://railway.app/button.svg)](https://railway.app/template/QbMnwX?referralCode=oaAwvp)

Your unsend instance is now live now.

## Step 3: Setting up a region

In order to send emails, you need to select an region in aws. Use a region where your users are located / where unsend is hosted. If you're confused just use `us-east-1`.

You can check available regions [here](https://docs.aws.amazon.com/general/latest/gr/ses.html)

Once you logged in to unsend, it will prompt you add ses configuration.

- Add the region
- Add the callback url, which is basically the app url. Note this should be accesible from internet. This is how you get the delivery status of the emails.
- You don't need to update the send rate, it's automatically based on your account.

<Warning>Don't forget to get the SES account out of sandbox mode.</Warning>

## Next steps

You're all set up now.

- Setup a domain.
- Create an API key.
- Start sending emails.
