Review Time
I downgraded my Mailchimp plan from approximately R$ 4,200 to a R$ 68 plan. Everything was correctly adjusted in my account until the 21st.
On the 22nd (Sunday), I received a vague email saying that “something needed attention.” The very next morning, on the 23rd, Mailchimp charged me the full amount of the previous plan (R$ 4,200), despite the downgrade already being completed.
This charge was clearly incorrect.
I immediately contacted support. Instead of refunding the improperly charged amount, they refused to issue a refund and offered to leave the money as account credit — suggesting I would not need to pay the R$ 68 plan for the next 60 months.
This is unacceptable. I am not a bank, and I do not provide interest-free loans to large corporations. When a company makes a billing mistake, the correct action is to refund the customer — not hold their money hostage as credit.
This experience raises serious concerns about Mailchimp’s billing practices. Customers should carefully monitor their invoices to avoid unexpected and wrongful charges.
Based on this experience, I do not recommend Mailchimp and strongly advise others to be cautious regarding their billing system and support.
–⭐ (Negative Star Review)
If negative stars were possible, this would be one. This experience doesn’t deserve zero — it deserves less than nothing.
For an entire year, Mailchimp quietly pulled $65 a month — $780 total — for a service I never once used. Their own system shows zero activity. Not “low usage.” No usage.
I even called them while I was in the hospital, dealing with real-life medical emergencies, trying to stop the bleeding — financially and emotionally. The charges kept coming anyway. The answer was still no. No pause. No empathy. No accountability.
Being sick is exhausting. Being hospitalized is terrifying. Watching a company continue to take money for nothing while you’re at your lowest feels like being kicked while you’re already down. This wasn’t just bad customer service — it felt inhuman.
This charge never should have existed. It should have been reversed. It should have been made right. Instead, I was treated like a line item on a balance sheet, not a person going through one of the hardest seasons of their life.
I caution people about doing business with a company that doesn’t care about anything but their bottom dollar. This company shows no compassion and appears to care more about money than about its clients.
This is the kind of experience that makes you lose trust in a brand forever.
–⭐ Negative star.
Waste of Money. I called their sales team and asked them specifically if my industry (research compounds), were against any policy compliance. Informed them that Klavio had an issue and wanted make sure Mailchimp did not before I signed up with them. I then spoke with an account manager and he also assured me that my industry was okay. I then signed up, and paid my dev team hundreds of dollars to create automations and templates. After 10 emails were sent out, I get a message from compliance that says I'm being suspended due to my line of business. I tried to plead with them but they just kept emailing me the same copy and paste BS not ackowledging that multiple people on their team misinformed me probably just to get a sale/commission. Do not work with these people.
I returned with the same small, legitimate customer list we previously used on the platform. Their automated system blocked my account, and despite a thorough manual review by a support agent, they still refused to reinstate it. This makes the service completely impractical for regular business use, especially during a rebrand or platform change. I’ve since switched to another provider.

I received excellent assistance in addressing two ongoing challenges. I truly value the tailored support. Tech issues can often be complex, and having someone guide you through the process, rather than navigating endless articles alone, is incredibly beneficial.
Sam helped me solve two recurring problems. I really appreciate the personalized help. Sometimes tech problems can be complicated and having someone walk you through it, as opposed to sifting through article upon article on your own, is super helpful.
