Email — Service/Transactional

Service/transactional email extension for Caffeine AI.

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.

module {
  public type SendResult = {
    #ok;
    #err : Text;
  };

  public func sendServiceEmail(
    fromUsername : Text,
    recipients : [Text],
    subject : Text,
    htmlBody : Text,
  ) : async SendResult;
};

Usage for sendServiceEmail:

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);
      };
    };
  };
};
