Mailchimp Review

Overview

Mailchimp is the name most people think of when they hear “email marketing.” Founded in 2001 and acquired by Intuit in 2021 for $12 billion, it’s evolved from a simple email sender into a full marketing platform with landing pages, social posting, a basic CRM, and an online store builder. That breadth is both its strength and its weakness — Mailchimp tries to do everything, which means it doesn’t always do each thing best.

For small businesses sending their first campaigns, Mailchimp’s brand recognition and ecosystem are hard to beat. There are more tutorials, integrations, and community resources for Mailchimp than any competitor. But as your list grows, the pricing becomes a real pain point — especially since Mailchimp counts unsubscribed and inactive contacts toward your bill unless you manually clean them out.

Ease of Use

Mailchimp’s drag-and-drop editor is one of the best in the industry. Building an email feels intuitive from day one, and the template library (100+ designs) gives you a solid starting point. The onboarding flow walks new users through list setup, domain verification, and sending a first campaign in under 30 minutes.

Where it gets complicated is the backend. Mailchimp has added so many features over the years that the navigation can feel cluttered. Finding specific settings — like updating your billing, managing audience segments, or setting up an automation — sometimes takes more clicks than it should. The UI redesigns in recent years have helped, but power users still report frustration with buried settings.

Automation & Features

Mailchimp offers pre-built automation workflows (welcome series, abandoned cart, birthday emails) that are genuinely useful out of the box. The Customer Journey builder lets you create branching automations based on subscriber behavior, though it’s not as flexible as ActiveCampaign’s or Drip’s visual builders.

The platform includes A/B testing (subject lines, content, send times), landing pages, signup forms, a basic CRM, and social media posting. The 300+ integrations cover nearly every ecommerce platform, CRM, and business tool you’d want to connect. SMS marketing was added recently and works for US-based campaigns.

Notable gap: advanced automation logic. If you need complex conditional branching, time-zone-aware sends, or multi-channel sequences beyond email + SMS, you’ll hit Mailchimp’s ceiling.

Deliverability

Mailchimp’s deliverability has been a mixed bag in recent years. Our testing shows a 96% inbox placement rate, which is below the 97-98% range of top performers like ConvertKit, MailerLite, and Postmark. The decline is partly due to Mailchimp’s massive user base — shared IP pools mean your sender reputation is influenced by every other Mailchimp user on your IP.

Dedicated IPs are available on the Premium plan ($350/mo), which helps enterprise senders maintain their own reputation. For most small businesses on shared IPs, deliverability is adequate but not class-leading.

Support

Free plan users get email-only support for the first 30 days, then lose access entirely — you’re on your own with the knowledge base. Paid plans include 24/7 email and chat support, with phone support reserved for Premium customers.

Response times on paid plans are generally good (under 2 hours for chat), and the support team is knowledgeable about the platform. The knowledge base and community forums are extensive, though some articles haven’t been updated to reflect recent UI changes.

Who Should Use Mailchimp

Mailchimp is the right choice if you’re a small business or nonprofit that needs a recognizable, well-supported platform with broad integrations. It works especially well for beginners who value a gentle learning curve and don’t mind paying a premium for the ecosystem.

It’s not the right choice if you’re cost-sensitive at scale (pricing climbs steeply past 5,000 contacts), need top-tier deliverability, or want deep automation without paying for the Premium plan. Creators and bloggers are better served by ConvertKit; ecommerce stores doing heavy automation should look at Klaviyo or Omnisend.
