Spreeflo vs Mailchimp: Which is better? (2026)

Yes — Mailchimp bills on your total audience count, which includes contacts who have unsubscribed and contacts you have archived, and it counts the same person twice if they exist in two audiences. Spreeflo bills only on marketing contacts, and stores unlimited non-marketing contacts free. In practice this is the single largest source of surprise on a Mailchimp invoice: a list that has been collecting addresses for three years is usually paying for a substantial number of people it can no longer legally email.

At 5,000 contacts Mailchimp Essentials runs about $75/mo and Standard about $100/mo, while Spreeflo is $36/mo on Starter and $52/mo on Professional — roughly half to a third, before counting the unsubscribed contacts Mailchimp bills and Spreeflo does not. Mailchimp adds SMS and a larger integration directory at that price, neither of which Spreeflo sells. What Spreeflo adds instead is browser push, per-recipient AI copy and agent access, none of which Mailchimp sells at any price — and the gap widens as your list grows, because Spreeflo’s per-contact rate flattens faster.

Mailchimp publishes an official MCP server for Mandrill, its transactional email product, but not for the marketing platform — so an AI agent can send transactional mail through it and cannot build a campaign, a journey or a segment. Reaching the marketing side means a third-party wrapper such as Composio, Zapier or Pipedream. Spreeflo’s hosted MCP server exposes the authoring surface directly, on every plan including Free, while refusing sends, publishes and deletes server-side.

Four. Mailchimp’s $13 Essentials plan caps a customer journey at four steps and does not include branching logic, which arrives on the $20 Standard plan along with 200-point journeys. Spreeflo’s $16 Starter plan ($13 billed annually) includes the complete journey builder with no step cap, no workflow count limit, and if/else plus multi-way splits from the first paid tier.

No — Mailchimp has no web push channel on any plan, including the $350/mo Premium tier. If you want to re-engage a lapsed visitor who never gave you an email address, Mailchimp cannot reach them. Spreeflo includes browser push notifications on its $24 Professional plan, on the same contact record as email, so a journey can try push when email goes unopened.

Yes — export your audience from Mailchimp as CSV and import it into Spreeflo, which maps email, name and tag columns automatically. Automations do not transfer between platforms and have to be rebuilt in Spreeflo’s journey builder. The 14-day trial gives full access to 2,000 emails and 1,000 contacts, which is enough to rebuild and test a welcome sequence before you cancel anything.
