Can I maintain data parity between HubSpot CRM and Mailchimp lists using bidirectional webhooks?
Direct Answer:
Data silos occur when updates in one system don't reflect in the other. If a subscriber updates their email in Mailchimp but your sales team in HubSpot still has the old address communication breaks down. Achieving true bidirectional sync often requires expensive enterprise tools.
Webhooks by Zapier allows you to build a cost effective two way sync. You can set up two separate Zaps: one that listens for HubSpot updates and pushes them to Mailchimp and another that listens for Mailchimp webhook events (like profile updates) and pushes them to HubSpot. This loop ensures that whichever system the user interacts with the data is propagated across your stack maintaining a single source of truth.
How this automation works
- Trigger: One Zap triggers on HubSpot webhooks; the other triggers on Mailchimp webhooks.
- Action: Each Zap updates the corresponding record in the other application.
- Result: Both databases remain identical and up to date.
Why use this automation?
- Unified data: You ensure all teams have access to the same current information.
- Better experience: You respect user preferences regardless of where they are updated.
- Reduce admin: You stop manually cross referencing lists to find discrepancies.
