This skill enables backend services to send reliable service and transactional emails (e.g., order confirmations, notifications) without mixing with marketing or verification workflows.
Configure the backend to import the email client, then call sendServiceEmail with a from username, a recipient list, a subject, and an HTML body to deliver a transactional email.

To send transactional emails from a Motoko backend canister, import the mo:caffeineai-email/emailClient.mo module and call sendServiceEmail with a from username, recipient list, subject, and HTML body to deliver messages.
Sending order confirmations and payment receipts from a backend canister is best handled by a dedicated service email client that triggers one-off transactional messages for backend events, returning a SendResult with #ok or #err(error).
No, you cannot modify the email client module when sending service emails because the Skill relies on the prefabricated mo:caffeineai-email/emailClient.mo module, which is designed to be used as-is.
A backend canister handles email delivery failures by returning a SendResult with #err(error) from the sendServiceEmail call, allowing the backend service to catch and process the failure state directly.
No, this service email approach does not work for marketing or verification workflows; it is specifically designed to send reliable service and transactional emails like order confirmations and system notifications without mixing workflows.
