Brew
First ESP with a built-in AI email marketing agency
Visit website →About
Brew is the first email service provider with an AI marketing agency built into the platform. Strategy, copywriting, design, segmentation, and analytics are all rebuilt around AI agents that run the workflow end to end instead of plugging into a legacy ESP as an add-on.
You describe the campaign in plain English. Brew generates the strategy, drafts copy in your brand voice, designs templates that follow your visual identity, segments the list, and schedules the send. It then watches deliverability and engagement and proposes the next campaign.
The product targets small marketing teams that want senior agency output without senior agency headcount, and it ships with native integrations to the most common CRM and analytics stacks.

Why we picked it
Brew made the cut for rebuilding the whole email stack around agents rather than bolting AI onto a legacy ESP — strategy, copy, and segmentation coming from the same agentic workflow is worth naming against tools where an AI feature sits awkwardly next to old manual tooling.
