Event emails in three languages

Making sure each person gets the right event email, in their own language.

A working sample we built to show how we would solve a problem like this. It is not a delivered project.

In plain terms

Wrong emails usually come from small gaps in the rules, such as a missing language or an outdated list. This demo models an event-email journey in three languages and checks it against ten invented registrations. It also includes a checker that shows who would fall through the gaps when moving from one email platform to another.

  • Each person gets the email in their own language.
  • A checker flags people who would be lost when changing email platforms.
  • Automated tests prove the rules do what they say.

What this does not claim: Built on made-up people and a simulator based on the email platform's public documentation. It has not been run on a live account.

Technical details
