# Debugging Emails

[Saleor Platform](https://github.com/saleor/saleor-platform) uses [Mailpit](https://github.com/axllent/mailpit) to catch all the emails sent by the Saleor.

Pros of using Mailpit during development:

-   Live preview of rendered emails.
-   No need to send emails to external services.
-   Test emails will be caught in the local environment, so there is no possibility of sending test data to actual customers.
-   It eliminates the possibility of sending emails to non-existing addresses, hurting email reputation.

## Configuration

-   When using the Saleor Platform, Mailpit should already be running on `localhost:8025`. When running Mailpit locally, follow the installation guide from [Mailpit repository](https://github.com/axllent/mailpit#installation).
-   Set the following required fields at the plugin configuration page for [AdminEmails](/developer/app-store/legacy-plugins/admin-emails.md) and [UserEmails](/developer/app-store/legacy-plugins/user-emails.md) (sender name and email are examples, you can adjust it to your needs):
    -   SMTP host: `0.0.0.0`
    -   SMTP port: `1025`
    -   Sender name: `Saleor`
    -   Sender email: `hello@example.com`
