Questions
Mailchimp vs Resend, answered
Mailchimp or Resend — which is better?
Neither, in the abstract. Mailchimp suits you if templates and a builder anyone in marketing can use immediately matters most; Resend if templates authored in React and versioned in your repo does. The honest trade-offs are: Mailchimp — Cost scales on total contacts, including people who never open anything. Resend — Engineering owns email here — there is no rich marketer-facing builder.
Is Mailchimp cheaper than Resend?
At least one of them is priced on usage rather than headcount, so there is no honest like-for-like figure. Model both against your own volume — contacts, events or tickets — before comparing, because the headline numbers measure different things.
Can we migrate from Mailchimp to Resend?
Usually yes, and the difficulty depends on history, integrations and headcount far more than on the two products. Data export quality is the thing to check first: ask both vendors what you can take with you before you commit to either. Our questionnaire produces a scoped estimate for the move.
What else should we consider besides Mailchimp and Resend?
In email marketing the other credible options are Brevo, Kit (ConvertKit), Klaviyo. Narrowing to two before you have written down your requirements is the most common way to end up with the wrong one.
