# Email — Service/Transactional
Service/transactional email extension for [Caffeine AI](https://caffeine.ai?utm_source=caffeine-skill&utm_medium=referral).
## Overview
This skill adds support for sending service and transactional emails from the backend canister. Use `sendServiceEmail` for order confirmations, notifications, and similar one-off emails.
# Backend
This component is for sending service/transactional emails.
There is the prefabricated module `mo:caffeineai-email/emailClient.mo` which cannot be modified.
- Use the sendServiceEmail function.
- Each recipient is sent an individual email
- It returns a SendResult which is #ok if the email is sent successfully otherwise #err(error) with the error text.
```mo:caffeineai-email/emailClient.mo
module {
public type SendResult = {
#ok;
#err : Text;
};
public func sendServiceEmail(
fromUsername : Text,
recipients : [Text],
subject : Text,
htmlBody : Text,
) : async SendResult;
};
```
Usage for `sendServiceEmail`:
```motoko filepath=src/backend/main.mo
import Runtime "mo:core/Runtime";
import EmailClient "mo:caffeineai-email/emailClient";
actor {
public func sendOrderConfirmationEmail(recipientEmailAddress : Text, username : Text, orderReference : Text) : async () {
let result = await EmailClient.sendServiceEmail(
"no-reply",
[recipientEmailAddress],
"Order " # orderReference # " confirmed",
"Hello " # username # ",\nYour order " # orderReference # " has been confirmed. Your items will ship tomorrow.",
);
switch (result) {
case (#ok) {};
case (#err(error)) {
Runtime.trap("Failed to send order confirmation email: " # error);
};
};
};
};
