Compare Mailchimp alternatives for AI email creation and lifecycle marketing, including Brew, Klaviyo, Kit, MailerLite, and ActiveCampaign.
Brew publishes this comparison. We reviewed the linked product documentation on September 28, 2026; this is a documentation comparison, not a claim of hands-on testing of every platform. Check current plan limits on the vendor's pricing page.
You are building an onboarding flow in Mailchimp, and you cannot add the fifth email because your Essentials plan caps each flow at four steps. The upgrade page is open in one tab, and a list of other email platforms is open in the next.
Mailchimp is still the default first email tool for many businesses. Teams usually start looking elsewhere for one of two reasons. They want AI to do more of the email creation, or their lifecycle program has outgrown the automation on their plan.
This guide compares eight alternatives on those two needs, with current plan details from each vendor's own pages. It also covers the option of keeping Mailchimp and changing only how emails are made.
We checked Mailchimp's pricing page on September 28, 2026. The Free plan covers up to 250 contacts and 500 sends a month, with a daily cap of 250. Essentials includes basic automation of up to four steps per flow. Standard adds advanced automations, custom templates and Intuit Assist, Mailchimp's generative AI features. Premium adds predictive segmentation and multivariate testing. Prices depend on your contact count and region, so check the page for your own numbers.
If Standard's automations and AI cover your needs, upgrading may be simpler than migrating.

Brew is built for teams that want AI to produce the emails. It reads your website and brand files into an editable brand document, generates complete emails from a prompt, and lets you compare and edit variants on a canvas. Automations come from a description, or from a remix of published example sequences in the flows gallery. Agents can do the same work through Brew's MCP server.
For a feature-by-feature view, see Brew vs Mailchimp.
Brew sends from your own domain. It can also export templates to Mailchimp, Klaviyo, HubSpot and other ESPs if you want to keep sending there. Integrations cover Stripe, Shopify, Clerk, Supabase and more for triggered email.
Brew's Free plan includes 500 AI credits and 1,000 sends a month with a Brew watermark. Growth is $99 a month (10,000 credits, 50,000 sends), and Pro is $249 a month (25,000 credits, 200,000 sends). Every plan includes every feature and unlimited seats.
Brew is newer than the other tools here, sends email only, and has no subscriber preference center.
Klaviyo is the usual move for ecommerce stores. Its free plan covers 250 active profiles and 500 email sends a month. Its AI agent, Composer, audits your account and drafts campaigns, flows and segments from your store data and brand settings. It sends nothing without approval. For a store on Shopify, the data depth is the reason to choose it.

Kit, formerly ConvertKit, is built for creators. The free Newsletter plan covers up to 10,000 subscribers with unlimited broadcasts, landing pages and forms. Visual automations and sequences start on the Creator plan, listed at $33 a month equivalent with annual billing for 1,000 subscribers and also includes Kit's MCP. Pro is listed at $66 a month equivalent with annual billing at the same tier. Annual billing saves about 17%.

MailerLite is a simpler, lower-cost option. The Free plan covers 250 subscribers and 2,500 emails a month with three automations. Comfort adds an AI writing assistant, 50 active automations and multivariate testing. Power adds unlimited automations and emails.
Brevo combines email, SMS, WhatsApp, transactional sending and a CRM. Its Free plan allows 300 emails a day, stores up to 100,000 contacts, and lets 2,000 contacts enter active automations. It fits businesses that want several channels from one budget vendor.

ActiveCampaign is the pick for complex automation, especially long B2B nurture. Every plan includes marketing automation. Starter allows five actions per automation, and Plus and above allow unlimited actions and add stronger segmentation. Its AI features are called Active Intelligence. Pricing depends on contact count, and every plan has a 14-day trial.

Customer.io fits product-led SaaS companies that trigger messages from product events across email, SMS, push and in-app. It takes more setup than Mailchimp, and it can segment on event history. New customers that have raised under $10M can apply to its startup program for up to 12 months free.

Loops is a SaaS-focused platform with marketing and transactional email in one account. The free plan covers 1,000 newest contacts and 4,000 sends a month. Loops prices paid plans by subscribed contacts, with unlimited sends. It fits software companies that want simpler event-triggered workflows than Customer.io.

If your list, forms and reports work well in Mailchimp, you can keep sending there. Brew connects to Mailchimp through OAuth and exports finished emails as templates. The Mailchimp campaign, audience and reporting stay where they are. This fits teams that are happy with their ESP and need help producing the emails.
Keep every list permission-based. Only email people who opted in, and keep a working unsubscribe under CAN-SPAM.
