Neither designs a finished, on-brand email. Kit’s AI writes subject lines and Mailchimp’s writes copy and subject lines; in both, you design each email in the editor.
Teams that move to Brew tell us AI drafts from tools like these rarely look like their brand, so someone still redesigns them.
Both price on the size of your list, so subscribers you rarely email still cost money.
Kit lists its prices at 1,000 subscribers: Creator is $39/month, or $33 billed yearly, and Pro $79/month, or $66 billed yearly. Mailchimp lists Essentials from $13/month and Standard from $20/month at 500 contacts, and Premium from $350/month at 10,000 contacts, so the two pricing pages start at different list sizes.
The free plans are far apart. Kit’s covers up to 10,000 subscribers but has no automations; Mailchimp’s covers 250 contacts and 500 sends a month. Kit counts only confirmed subscribers; Mailchimp counts unsubscribed contacts too, once for every audience they are in.
Brew bills on emails sent and AI credits, with unlimited contacts: Growth is $99/month for 50,000 sends and 10,000 AI credits.
Brew is fully agentic: your agent designs on-brand emails, sends them and runs your automations. Unlimited contacts on every plan. OAuth and organization-scoped MCP connections ask you to confirm live sends and launches. Brand-scoped API keys can execute permitted calls without the MCP confirmation step.
Connect Claude, ChatGPT, Cursor or Grok over MCP and your agent gets every Brew tool. It designs emails from your brand, builds audiences, runs automations and schedules sends. OAuth and organization-scoped MCP connections ask you to confirm live sends and launches. Brand-scoped API keys can execute permitted calls without the MCP confirmation step.
Paste your website and Brew writes your brand into two files your agent reads for every email. Describe the email and it appears on the canvas, ready to edit by hand or in chat.

Kit, for most creators: it sells digital products, paid newsletters and memberships, its free plan covers up to 10,000 subscribers, and Creator and Pro include unlimited automations. Mailchimp suits a business that wants a website builder and product recommendations next to its email.
It depends on your list. Kit’s free plan covers up to 10,000 subscribers without automations; Mailchimp’s covers 250 contacts. On paid plans, Mailchimp Essentials starts at $13/month for 500 contacts, and Kit Creator is $39/month for 1,000 subscribers, or $33 billed yearly. Kit bills only confirmed subscribers; Mailchimp counts unsubscribed contacts, once for every audience they are in.
They do different things. Mailchimp’s AI writes copy, subject lines and preview text and fills in flow templates on Standard and up, and its Claude and ChatGPT connectors draft campaigns; its MCP server searches the docs. Kit’s AI writes subject lines, and Kit MCP lets Claude, ChatGPT and other clients manage subscribers and draft broadcasts and sequence emails on Creator and Pro. A Kit broadcast sends only after you click Confirm in Kit. Neither designs a finished, on-brand email; Brew does.
Brew, if you want an agent to run your email. Your agent designs finished, on-brand emails from your brand, sends them and runs your automations, with unlimited contacts and seats on every plan. Brew is email only, so landing pages, SMS and product sales stay in another tool.
Yes. Connect Mailchimp in Brew and save any email as a Mailchimp template, ready for your campaigns and flows. For Kit, export the finished email as HTML and save it as a custom template, which Kit accepts in HTML and CSS.
