# Custom Email

> Replace the default emails CoreBase sends to your end users.

By default, CoreBase sends a simple welcome email when someone signs up through
[User Accounts](/authentication). Custom email templates let you replace it with your own.

<Note>
  If a template exists for your project, it's used automatically in place of the default
  welcome email — you don't need to wire anything up beyond creating it.
</Note>

## Create a Template

```typescript theme={null}
const { data, error } = await corebase.customEmail.create({
  name: 'welcome',
  subject: 'Welcome to {{projectName}}, {{name}}!',
  body: '<p>Hi {{name}}, thanks for signing up.</p>',
});
```

## List, Get, Update, Delete

```typescript theme={null}
const { data: templates } = await corebase.customEmail.list();
const { data } = await corebase.customEmail.get(template.id);

await corebase.customEmail.update(template.id, { subject: 'Welcome aboard, {{name}}!' });
await corebase.customEmail.delete(template.id);
```

## Send Manually

Outside the automatic signup flow, you can send a template directly:

```typescript theme={null}
await corebase.customEmail.send(template.id, {
  to: 'user@example.com',
  name: 'Ada',
  projectName: 'My App',
});
```
