Create an HTML receipt

Mich can produce a receipt three ways. Which you want depends on what you have installed and how you send things.

HTML needs nothing installed

Create HTML Letter renders the full receipt as HTML. You can preview it in a browser, print it from there, or paste it into whatever email client you already use. No PDF engine, no email account.

Enable it from Settings - Templates & Folders, under HTML receipts.

PDF letters

Create PDF Letter converts the Word record to PDF using an application already on the machine: Microsoft Word or LibreOffice, whichever you select in Settings. If neither is installed, this action cannot work; HTML has no such dependency.

Opening what you produced

Open Record Folder (A) and Open Letter Folder (B) jump to the generated files on disk.

Generated file paths are stored relative to their output folder, so you can move the whole folder later, point Mich at the new location, and every link still works.

Emailing

With email configured, Email PDF Letter and Email HTML Receipt send directly, and Check Delivery asks your provider what happened to the message — delivered, bounced, blocked, reported as spam, or failed to send. Delivery outcomes are written to the audit log.

What Check Delivery can tell you depends on your provider and plan:

• Resend reports full delivery status on the free plan, keeping 30 days of history. The API key must have Full access — a key with Sending access sends mail normally but cannot read status, so sends succeed while this check comes back empty.
• Mailgun reports full status too, but its free plan keeps only one day of history, so anything emailed more than about 24 hours ago has nothing left to report.
• SendGrid reports problems only — bounces, blocks and spam reports. A message that arrived normally has nothing to report, so finding nothing usually means nothing went wrong.
