The Verdict

Mailchimp and Resend solve different problems — Mailchimp is for marketing campaigns, Resend is for transactional email sent from your app's codebase. Teams comparing them are usually trying to stop overpaying Mailchimp for system emails (password resets, receipts, alerts) that don't need a marketing platform at all. If that's your case, move transactional sends to Resend and keep Mailchimp (or drop it) only for actual newsletters.

How to switch from Mailchimp to Resend

1In Mailchimp, go to Audience > All Contacts > Export Audience to download your contact list as a CSV, and use the Campaigns export or API to save a record of past campaign content.
2Sign up for Resend at resend.com and verify your sending domain (add the DKIM/SPF DNS records Resend provides).
3Identify which emails in your app are transactional (password resets, receipts, alerts, confirmations) — these are the ones to move to Resend, not your newsletters.
4Install the Resend SDK for your stack (Node, Python, etc.) and replace Mailchimp API calls for those transactional emails with Resend's `emails.send()` calls.
5If you use templates, rebuild them as React Email components or plain HTML in your codebase, since Resend doesn't import Mailchimp templates directly.
6Test delivery in staging, monitor bounce/delivery webhooks in Resend's dashboard, then cut over production traffic and keep Mailchimp only for marketing campaigns if still needed.

Mailchimp vs Resend: common questions

How do I export my data from Mailchimp before switching?+

Go to Audience > All Contacts > Export Audience to download a CSV of your contact list. For campaign history, use Mailchimp's Campaign Export or the API to pull past sends. Note that Mailchimp exports contacts and campaign metadata, not template code, so transactional email templates will need to be rebuilt for Resend.

What do I lose if I move transactional emails from Mailchimp to Resend?+

You lose Mailchimp's drag-and-drop template editor and its audience-based segmentation, since Resend doesn't have either. You keep (and typically improve) deliverability and speed for system emails like password resets, since Resend is built specifically for that use case.

Is Resend's free tier enough for a small team?+

Resend's free tier covers 3,000 emails/month (100/day), which is enough for early-stage apps sending signup confirmations, password resets, and notifications. If you're also sending marketing newsletters, you'll still need Mailchimp or another marketing tool alongside Resend.

Does Resend integrate with the tools I'm already using?+

Resend has official SDKs for Node.js, Python, Ruby, PHP, Go, and Java, plus a REST API, so it integrates directly into your backend code. It doesn't have native integrations with CRMs or marketing tools the way Mailchimp does — you build the integration yourself via API calls.

Will switching actually save money over time?+

Yes, if the emails in question are transactional. Mailchimp charges based on total contacts regardless of email type, so a growing contact list with mostly system emails gets expensive fast. Resend charges by email volume sent, which is usually far cheaper for transactional-only use cases.
