Sync Mailchimp Unsubscribes to HubSpot

Tools that fit

Watch out for

• ⚠ HubSpot API rate limits can block updates, so implement exponential backoff logic before retrying failed requests.
• ⚠ Email duplicates may cause conflicting opt-out statuses in HubSpot, so verify existing contacts before creating new ones.
• ⚠ Webhook signature verification is critical for security, so validate the HMAC header to ensure requests originate from Mailchimp.
• ⚠ Slack channel permissions might restrict bot posting, so pre-configure the app scopes and test access in a dedicated channel.
