When you’re starting out, Mailchimp feels like the logical choice. It’s the household name of email marketing, it’s easy to set up, and that friendly chimp makes everything feel approachable.
But as your business grows and your marketing matures, many brands hit a ceiling. The platform that seemed cheap starts eating into your margins, not just through the subscription, but through missed revenue and manual workarounds.
At Greenfish Marketing, we care about efficiency and return. Here are five reasons Mailchimp might be costing you more than you realise.
1. You’re Paying for People Who Will Never Buy From You
Mailchimp bills on your total contact count, and that count includes more than your active subscribers.
Subscribed, unsubscribed and non-subscribed contacts all count. Non-subscribed contacts are people who bought from you but never opted in to marketing, so you can’t email them a campaign, yet you’re still paying to store them.
If you have 5,000 active subscribers plus 1,000 people who’ve unsubscribed over the years, you’re billed for 6,000.
It gets worse if you run more than one audience. Your contact total is counted across all of your audiences, so the same customer sitting in two audiences (say, Australia and New Zealand) is counted twice.
You can archive contacts to take them off your bill, but Mailchimp won’t do it for you. Unless someone on your team is doing it every month, you’re paying a tax on people who have already told you they don’t want your emails.
2. The “Growth Tax” on the Features That Actually Drive Revenue
Mailchimp has some genuinely good tools, but the ones that move revenue sit behind the higher plans.
On Essentials, automation flows are capped at four steps. Branching logic (the “if this, then that” decisions that make a welcome series or abandoned cart flow work properly) is only available on Standard and Premium. So is advanced segmentation: on Free and Essentials, a segment can only use up to five conditions.
The problem is that Standard is priced on contacts too. It starts at A29.11amonthfor500contacts,butat75,000to100,000contactsit’sA1,164.57 a month. That’s nearly A$14,000 a year, and the bill grows with your database whether or not those contacts are buying.
3. Send Limits and Automatic Overages
Every paid Mailchimp plan comes with a monthly send cap tied to your contact tier: 10 times your contact limit on Essentials, 12 times on Standard and 15 times on Premium.
That sounds generous until you start sending properly. A growing ecommerce brand running two or three campaigns a week, plus welcome, abandoned cart and post-purchase flows, can burn through that allowance in a big month like Black Friday.
When you go over, Mailchimp doesn’t stop you. It bills you automatically for the overage. The same applies if your contact count creeps over your tier mid-cycle. You won’t notice until the invoice arrives.
4. eCommerce Integration: Wide but Not Deep
Mailchimp offers one-click integrations with Shopify and WooCommerce, which covers the basics. But for serious ecommerce brands, the data often feels bolted on rather than built in.
Platforms designed for ecommerce let you trigger and segment on granular behaviour, like the specific category a customer browsed or their predicted lifetime value. Mailchimp now offers predictive tools like customer lifetime value and purchase likelihood, but only on Standard and Premium. You’re paying for a higher tier to get the data your marketing should be built on.
5. Time Is Money: The Complexity of Automation Flows
Mailchimp has grown from a simple email sender into an all-in-one marketing platform covering email, SMS, social, landing pages and more. Having everything in one place sounds good, but it’s made the interface busier.
Building a multi-step automation in Mailchimp’s Marketing Automation Flows (formerly the Customer Journey Builder) often takes more clicks and troubleshooting than it does on platforms built around automation. For a busy founder or marketing manager, every hour spent wrestling with a welcome flow is an hour not spent growing the business.
The Verdict: Is It Time to Move?
Mailchimp is a solid tool for side hustles, small service businesses and brands that just need to send a monthly newsletter. But if you’re a growing ecommerce brand, or your revenue depends on well-built automation, you may be outgrowing the Chimp.
Before you pay your next invoice, ask yourself: Is my email platform helping me grow, or am I working hard just to keep it running?
