Pick one source of truth for your trigger

When several tools could all technically start the same workflow, pick exactly one and route everything else through it first. Otherwise you end up guessing which version of a record is the real one whenever something looks off.

This comes up constantly with contact information — a name might live in an inbox, a spreadsheet, and a form tool all at once, each slightly out of sync. I've built on outdated information this way myself, without realizing it until something looked off. Choosing one place as the real record, and having everything else feed into it rather than trigger separately, keeps your workflow trustworthy even as your tools multiply.

This single decision, made early, prevents most of the confusing "why did this run twice" conversations later.

Try this today: pick the one tool that should be the real source for your busiest workflow, and make sure nothing else can trigger it independently.
