What was built
Moving the publisher's newsletter estate off Inxmail into HubSpot: around 220,000 contacts across 22 lists, for two companies, without losing the consent record that makes sending them legal in the first place.
| Area | Description |
|---|---|
| Field mapping | Data prep and mapping from the Inxmail export into the HubSpot contact model |
| Lists to subscriptions | Lists rebuilt as HubSpot subscriptions, each carrying its original consent date rather than the import date |
| Suppression | Hard bounces and the legal blacklist carried across so a suppressed address stays suppressed |
| Tags & sources | Campaign, source and Inxmail labels preserved for segmentation after the move |
| GDPR record | The raw export archived as the evidence trail for the consent that was migrated |
| Preference pages | DSGVO-compliant preference and subscription pages for both companies |
| Cutover | A daily sync during the parallel phase, then delta sync and cutover |
Quality control is a review loop rather than a single import: the client spot-checks subscription mapping and Kopfadresse handling, and the import script is corrected against what they find.
Tech stack
| Technology | Role |
|---|---|
| HubSpot | Destination CRM, subscriptions, marketing email |
| Inxmail | The source system being retired |
Project stats: 18 tasks, ~7h so far, running since June 2026.
