Email marketing and newsletters

Should you build your own Mailchimp?

Buy it. Sending email is easy. Getting it into the inbox isn’t.

BUY

Short answer

You can build signup forms and send through an email API. But then deliverability, bounce and complaint handling, unsubscribe compliance (CAN-SPAM, GDPR) and list hygiene are all on you. At 500 contacts, Mailchimp is about $13 a month. If price is the problem, switch to a cheaper email tool instead of building one.

Mailchimp pricing in 2026

PlanBilled yearlyBilled monthly
Essentials, up to 500 contacts Typical$13/mo–
Standard, up to 500 contacts$20/mo–
Standard, up to 2,500 contacts$60/mo–
Standard, up to 5,000 contacts$100/mo–

Free plan: Up to 250 contacts and 500 emails a month

Paying too much? The Free plan covers a list under 250 contacts. Essentials at $13 is enough if you send newsletters without long automations, since Standard adds longer automation flows and AI features.

Billed monthly, read in USD on Mailchimp’s pricing page at each contact tier. Mailchimp offers annual billing only through sales, for Standard and Premium at 10,000+ contacts. Premium starts at $350 a month. Checked October 26, 2026.

Buying is about $1,627 cheaper over 3 years.

3-year totals. Building includes your time, upkeep, running costs and one month of an AI app builder ($25). Change any number to match your situation.

What you’d build

  • Signup forms that write to your own contacts table
  • Sending through an email API (e.g. Amazon SES or Resend)
  • Unsubscribe links, a suppression list, and bounce and complaint webhooks
  • Templates and a basic send scheduler

Our estimate for an email-sending API at modest volume.

What you’d give up

  • Sending infrastructure with an established reputation
  • A drag-and-drop editor and template library
  • Automations, segments and A/B tests
  • Open and click reports

Risks the price doesn’t show

DeliverabilityHigh

A new sending setup lands in spam easily.

ComplianceHigh

Unsubscribes and consent records are legal requirements.

BouncesMedium

Ignoring bounces and complaints gets your domain blocked.

When the verdict flips

Switch to HYBRID if you only send transactional email (receipts, password resets). That belongs in your app through an email API anyway.
