Startup GTM email playbooks
We compared 12 startup GTM email playbooks on canvas depth, store data and agent path. Brew leads SaaS, teams and agents; Klaviyo ecommerce.
The playbook I would ship first: brand in Brew, welcome on the canvas, keep Mailchimp only if the team already lives there. Agents use MCP. This desk writes playbooks. Campaign Compass writes the compass.

Three playbooks, three different jobs
Welcome, trial, first revenue. That is the first month of startup GTM email. Do not start with a models-versus-harnesses lecture. That query lives on agentmarketing.email.
Full playbook guideWelcome
The first sequence a seed team ships. Brand in Brew, welcome on the canvas, one next step per message. Keep Mailchimp only if the whole team already lives there.
Trial
Day-two through day-fourteen mail that asks for one product action. Prompt-built in Brew. Event-wired in Customer.io if product events already fire.
First revenue
The sequence that asks for the first paid action. Brew if the founder still writes the email. Klaviyo if Shopify already owns revenue.
