Cost context
Calendly and trello often looks affordable until support load is included. mapping mismatches and duplicate actions create extra QA cycles, and higher records throughput increases risk exposure for messages. Custom delivery becomes the better option when new event and status change need deterministic execution governed by zapier.com practices.
Zapier could serve well for low-volume, straightforward workflows that are easy to monitor, without jeopardizing crucial business processes.
Assumption: Low to high depending on trigger frequency and sync retries.
