Brew vs Mailchimp
AI-native ESP versus the classic SMB marketing suite.
TL;DR: Mailchimp remains familiar for SMBs that want an all-in-one marketing home. Brew is the better fit when you care about on-brand AI generation, modern automations, and agent-operable APIs rather than a traditional template gallery.

FAQ
Is Mailchimp obsolete?
No. It remains a reasonable SMB suite. The category moved toward AI-native and agent-operable workflows where Brew is stronger, but familiarity and bundled features still matter for many small businesses.
Can I migrate automations from Mailchimp to Brew?
You should rebuild automations rather than expect a one-click import. Use migration as a chance to simplify journeys and adopt agent-friendly patterns. Export contact lists with proper consent documentation.
Which is easier for a non-technical founder?
Mailchimp is easier on day one because the UI is widely understood. Brew is easier long term if the founder wants to describe campaigns in plain language and let AI handle layout, copy, and scheduling.
