# Supercycle notifications

> The emails Supercycle sends your customers, and how to edit, brand, and deliver them

Supercycle sends its own emails to customers when something happens on their rental, return, or subscription, such as a return being requested or credits being returned to a membership. Each email is a template you can reword under <Icon icon="shopify" iconType="solid" /> **[Languages](https://admin.shopify.com/apps/supercycle/settings/languages)**, and the branding, reply-to address, and delivery are set under <Icon icon="shopify" iconType="solid" /> **[Emails](https://admin.shopify.com/apps/supercycle/settings/emails)**.

<Note>
  Emails are sent from `noreply@notify.supercycle.com`. To send from your own domain, connect a [custom SMTP server](#custom-smtp) or contact support from the app.
</Note>

## Custom SMTP

By default, Supercycle delivers all transactional emails through its own mail provider. To send them from your own domain and mail infrastructure, connect a custom SMTP server. When it's on, customer emails go through your server with the **From** address you set. If the integration is turned off or removed, Supercycle falls back to its default provider, so no emails are lost.

<Tip>
  Use a dedicated transactional email service such as [Postmark](https://postmarkapp.com/) or [Resend](https://resend.com/) rather than a general-purpose mailbox. They offer better deliverability, bounce handling, and analytics for transactional mail.
</Tip>

You need these details from your SMTP provider, for example Postmark, Resend, Amazon SES, SendGrid, Mailgun, or your own mail server:

* **Host.** The SMTP server hostname, for example `smtp.sendgrid.net`.
* **Port.** Typically `587` for STARTTLS or `465` for implicit TLS.
* **Username and password.** Credentials for an account authorized to send mail.
* **From address.** The address in the **From** header. It must be authorized by your provider, with SPF, DKIM, and DMARC records on your domain.
* **Authentication method.** Usually `plain`. `login` and `cram_md5` are also supported.

### Connect an SMTP server

<Steps>
  <Step title="Open emails">
    Go to <Icon icon="shopify" iconType="solid" /> **[Emails](https://admin.shopify.com/apps/supercycle/settings/emails)**.
  </Step>

  <Step title="Turn on Custom SMTP">
    Under **Custom SMTP** at the bottom of the page, turn the section on, then select **Configure SMTP server**.
  </Step>

  <Step title="Enter your SMTP details">
    Enter **Host**, **Port**, **Username**, **Password**, and **From address**. Set an **Authentication** method and, if needed, a **HELO domain**. Leave **Enable STARTTLS** ticked unless your provider requires otherwise.
  </Step>

  <Step title="Save">
    Select **Save**. Your password is encrypted at rest.
  </Step>

  <Step title="Send a test email">
    Select **Send test email**. Supercycle sends a test message to the shop's contact email address with the credentials you provided. If the test fails, the error your SMTP server returned is shown so you can correct the host, port, credentials, or sender address.
  </Step>
</Steps>

To update credentials, select **Edit** on the **Custom SMTP** section. Leave the password blank to keep the existing one. To stop using your server, turn the section off or select **Remove**. Supercycle reverts to its default mail provider for all future emails.
