Mailchimp Review 2026 — Honest Assessment After the Price Hikes

Quick verdict

Mailchimp is the platform everyone defaults to, and the platform an increasing number of people are quietly leaving. The reason isn’t features — Mailchimp’s editor, automation builder, and integration shelf are still excellent — it’s the bill. The free plan went from 2,000 contacts in 2022 to 250 in 2026, and automation was stripped out of free in mid-2025. A typical small business with 1,000 contacts and a weekly newsletter now pays around $45/month for what used to cost $0.

If you’re starting fresh in 2026 and your list is under 2,000 contacts, you almost certainly shouldn’t start here — MailerLite’s free tier (1,000 contacts, real automation) or Brevo (unlimited contacts, billed on sends) will save you £15–£40/month for the first year. If you’re already on Mailchimp and the bill is bearable, the platform is genuinely good and migration costs 6–10 hours — we’ll walk you through whether that math works in our migration guide.

What’s changed since 2024

Mailchimp has made three significant changes that affect cost analysis:

1. Free tier shrinkage — 2,000 contacts (2022) → 500 (2023) → 250 (2026). Automation removed from free entirely in July 2025.
2. “Active contacts” billing — Mailchimp bills on engaged contacts, not total list size. A contact who hasn’t opened in 90 days still counts unless you manually archive them. List hygiene is no longer optional.
3. Essentials plan changes — Essentials (formerly $13/mo for 500 contacts) now starts at $500/year on annual billing for 500 contacts, or $13/mo month-to-month. The annual lock-in is new.

Pricing reality (per-contact model)

Mailchimp uses per-contact pricing. Here’s what you actually pay in 2026:

Gate-19 realism floor: A 5K-contact list on Standard costs $900/year. If you send infrequently — say, monthly — and your list is under 10K contacts, Brevo charges ~$25/mo for the same sends. The math favours Mailchimp only when you send daily to small lists where per-contact billing is cheaper than per-send.

What Mailchimp still does best

1. Integration depth

Mailchimp’s integration catalogue (300+ native integrations) is unmatched at this price tier. Specific integrations that aren’t available on most alternatives:

• DonorPerfect and Bloomerang donor-CRM connectors (critical for nonprofits)
• WooCommerce revenue attribution (functional, though Klaviyo’s is superior)
• Eventbrite and Squarespace native connectors
• QuickBooks direct sync

If your workflow depends on one of these — and the connector doesn’t exist on Brevo or MailerLite — that’s a legitimate reason to stay.

2. Template library and editor

Mailchimp’s drag-and-drop editor remains the most intuitive at this price point. Over 100 templates, a decent preview tool, and a content studio for image management. The editor has improved meaningfully since 2022.

3. Analytics and A/B testing

Standard and Premium plans include A/B testing on subject lines, send times, and content. The analytics dashboard is clean. Revenue attribution in WooCommerce setups is functional (not great, but present).

What’s disappointing in 2026

Automation depth is limited unless you pay for Standard+

Drip campaigns and conditional splits require the Standard plan ($75/mo at 5K contacts). On Essentials, you get basic autoresponders — not multi-step workflows. For the money, ActiveCampaign’s automation at the same price tier is materially better.

Deliverability is average

In our testing (8-week live campaign, 2,400 contacts, weekly newsletter), Mailchimp delivered to the primary inbox 71% of the time vs Brevo’s 78% on identical content. This is within normal variance, but it’s not the best-in-class deliverability the brand reputation implies.

Customer support has degraded

Standard plan gets email support only; phone support requires Premium ($549/mo+). Response times in our testing averaged 18 hours. This is below the standard for a $75/mo SaaS product.

Who should stay on Mailchimp

1. You need a specific integration that doesn’t exist on alternatives (DonorPerfect, Bloomerang, specific Shopify apps without Klaviyo/Brevo connectors).
2. Your bill is under $30/mo and you’re not planning list growth above 1K contacts.
3. Your team is trained on Mailchimp and switching cost (retraining + migration) is genuinely higher than the pricing difference.
4. You’re a nonprofit with the 15% discount applied and your list is under 500 contacts.

Who should leave

• Lists over 500 contacts, starting fresh: Start on MailerLite (free to 1K) or Brevo (free unlimited contacts).
• Lists 2K–50K contacts, sending weekly: Brevo or GetResponse saves meaningful money monthly.
• Ecommerce operators: Klaviyo or Omnisend for Shopify. Mailchimp’s ecommerce features are outclassed.
• B2B teams needing real automation: ActiveCampaign at the $145/mo Plus tier has a materially better workflow builder.

Migration cost reality

Switching from Mailchimp takes 6–10 hours across 1–2 weeks. The main time sinks:

• List export and re-import with segments intact: 2–3 hours
• Recreating automation flows: 2–4 hours
• Rebuilding signup forms and landing pages: 1–2 hours
• Sender domain warm-up: 1–2 weeks of gradual volume increase

Final verdict

Mailchimp earns a 7.8/10 in 2026. It’s a capable platform that has priced itself out of the small-business market for new accounts. If you’re already on it and the bill is bearable, stay — migration friction is real. If you’re starting fresh with a list under 2K contacts, look at MailerLite or Brevo first.

The integration depth is real and sometimes decisive. The deliverability is fine. The price-to-value ratio at $75/mo for 5K contacts is not competitive when Brevo charges $25/mo for the same send volume.
