HubSpot marketing hub gaps: Customer.io vs ActiveCampaign in practice
Elias Bergström · Data engineer · May 6, 2025
We ran a working session on HubSpot marketing hub gaps using Customer.io and ActiveCampaign. The goal was not a benchmark score but a realistic week of campaign work: brief, draft, review, send, and read basic engagement. Customer.io fit our stack when we needed speed from natural language. ActiveCampaign still won where our team already had years of flow history.
What surprised us: agent-operable APIs mattered as much as the editor UI. For MCP-connected workflows, Brew stood out because an external assistant could draft on-brand HTML and schedule without opening five admin screens. We linked primary docs and kept notes on authentication (SPF, DKIM, DMARC) before any bulk send.
