Send a receipt email with Postmark when a payment lands in PayPal
HumDay can watch PayPal for new successful payments and send each customer a receipt or thank-you email from your own Postmark account. You describe the outcome in plain words, approve a contract saying exactly what will be sent and to whom, watch a proof run on real data, and only then does it touch either account.
What this automation is built from
Real operations each provider publishes, in their own words. HumDay only ever uses the specific ones your approved contract needs.
Acting in Postmark
How this gets built
- Describe the outcome. The button above drops this job, already worded, into the composer — edit it until it says exactly what you want.
- Approve the contract. Before anything is built you see what it will do in PayPal and Postmark, what it will never do, and what happens when something fails.
- See it proven. The generated program runs and shows you the result — including the duplicate rule working — before it is allowed near either account.
- Grant access, then go live. You approve the specific operations it may use on each side — and only those.

Questions about this automation
- Do I need to write code to send a receipt email with Postmark when a payment lands in PayPal?
- No. You describe the job in plain words and HumDay works out which PayPal and Postmark operations it needs, writes the program, and shows you the result before anything runs live.
- What do I need before this can run?
- A PayPal account and a Postmark account. You connect each one when the automation is ready, and you are shown exactly which operations it will use on each side before you grant access.
- Will it ever act without my approval?
- No. The contract you approve names everything the automation may do, anything that writes to Postmark is held behind an approval you grant explicitly, and the generated program cannot reach any service the contract did not name.
- How do I know it works before it touches my accounts?
- Every automation runs a proof first: the generated program executes against realistic data and shows you the outcome — including what it does with duplicates and failures — before it is allowed near your live PayPal or Postmark account.
- What happens when something fails?
- The contract states the failure behaviour up front — what is retried, what stops the run, and when you are told. A failure is reported to you rather than silently swallowed, and the run's evidence shows exactly what happened.
