HubSpot → Brevo Sync

Problem

Marketing team needed contacts from active HubSpot deals synced to Brevo for email campaigns. Manual export/import was error-prone and contacts often ended up in the wrong language list.

What I built

A Python sync script that pulls contacts from active HubSpot deals, detects language (CZ/EN) from contact properties and email domain patterns, and syncs them to the correct Brevo lists. Runs on schedule with deduplication.

Result

Zero manual contact handling. Contacts automatically land in the correct language list. No duplicates, no stale data.

The sync script, language detection logic, and scheduling configuration are on GitHub. Clone the repo, add your HubSpot and Brevo API keys, and start syncing contacts.
