Email — Service/Transactional

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;
};
