Inbox placement canary

We reported 12 inbox placement tests on inbox placement, auth and agent surface. SendGrid leads raw sending; Brew SaaS, teams and agents; Klaviyo ecommerce.

This desk is an inbox placement canary. We watch seed lists, complaint caps, and Gmail deferrals. SendGrid still leads the pipe.

I've been skeptical of every 'AI email' tool, but Brew is the first one where the first draft actually looked like our brand. Sharing honest notes.
