Mailchimp is the email platform everyone starts with. It is the default choice. The safe option.
But the Trustpilot rating tells a different story: 2.9/5. 67% of reviews are 1-star.
I have used Mailchimp on and off for 8 years. Here is what has changed, and why you should probably look elsewhere.
Quick Verdict
Mailchimp is fine for absolute beginners with under 500 contacts. Everyone else will outgrow it quickly and face painful overage charges. The 67% 1-star Trustpilot rating is not an accident.
What Mailchimp Actually Is
Mailchimp started in 2001 as a simple email platform for small businesses.
Intuit acquired it in 2021 for $12 billion.
Since the acquisition, long-time users have watched in frustration as:
- Prices increased
- Features were removed from free plans
- Support quality declined
- Billing became more aggressive
The platform still works. It is still the most recognizable brand in email marketing.
But the magic is gone.
The Trustpilot Disaster (2.9/5 Rating)
Rating breakdown:
- 67% of reviews are 1-star
- 19% of reviews are 5-star
- 1,297 total reviews
The recurring complaints:
Billing & Overcharging (#1 complaint)
- "Showed $14/mo in dashboard then charged me $566"
- "I deleted contacts but still got charged for them"
- "Mailchimp is deliberately unclear about unpause conditions"
- "Charged my card for $110 5 months after I paused"
Account Suspensions (#2 complaint)
- "Out of the blue, blocked our account for compliance violation"
- "Suspended with no explanation, export disabled"
- "They will ruin your business with senseless suspensions"
Support (#3 complaint)
- "Customer service is nonexistent"
- "No phone number, impossible to reach"
- "Support is terrible, asked questions like why do you think it is not working"
The Pricing Model (Contact-Based Pain)
Mailchimp charges for contacts, not email sends.
Free plan:
- 500 contacts
- 1,000 emails/month
- NO automations
- NO A/B testing
- Mailchimp branding on emails
Essentials plan:
- Starts at $13/month (500 contacts)
- 10X contacts email send limit
- Only 4 automation flow steps
- 5,000 contacts = ~$75/month
Standard plan:
- Starts at $20/month (500 contacts)
- 12X contacts email send limit
- Up to 200 automation flow steps
- 5,000 contacts = ~$100/month
The problem: Deleted contacts still count toward your monthly limit until your billing anniversary.
This is the #1 source of surprise charges.
The Free Plan Reality
Mailchimp free is severely limited:
- 500 contacts only (worst among major platforms)
- NO marketing automation flows
- NO A/B testing
- Limited templates
- Mailchimp branding required
- Support for first 30 days only
For comparison:
- MailerLite free: 500 contacts, HAS automations, landing pages
- ConvertKit free: 10,000 subscribers, HAS automations
- beehiiv free: 2,500 subscribers, HAS automations
- Brevo free: 300 emails/day, HAS automations
Mailchimp free is basically a trial disguised as a free plan.
What Mailchimp Does Well
1. Brand Recognition
Everyone knows Mailchimp. Clients recognize the name. Bosses approve the expense.
This matters for agencies and businesses serving risk-averse clients.
2. Beginner-Friendly Interface
The drag-and-drop editor is intuitive. The template library is massive.
For absolute beginners, Mailchimp is the easiest starting point.
3. 300+ Integrations
Shopify, WooCommerce, Canva, Zapier, Square, Wix, Squarespace, Stripe, Salesforce, LinkedIn, Facebook, WordPress...
If you need an exotic integration, Mailchimp probably has it.
4. All-in-One Platform
Email + landing pages + pop-ups + postcards + social ads.
One platform does many things.
What Mailchimp Does Poorly
1. Value for Money
At 5,000 contacts:
- Mailchimp Standard: ~$100/month
- MailerLite: ~$35/month
- Brevo: ~$39/month
Mailchimp costs 2-3x more for similar features.
2. Contact-Based Pricing
You pay for every contact in your database, whether they engage or not.
Delete 1,000 subscribers? Still counts toward your limit until billing anniversary.
This is the #1 source of surprise charges.
3. Feature Gating
Essential features like automation and A/B testing are gated behind paid tiers.
Free plan is basically unusable for any serious email marketing.
4. Deliverability Issues
Some users report emails flagged as phishing due to Mailchimp redirect links.
One review: "My company emails started being flagged as phishing due to redirect links created by Mailchimp."
The Long-Time User Exodus
15-year customers are leaving in droves.
One Trustpilot review: "We have been with Mailchimp for over 15 years. Back when we were a small startup they were helpful, human, and felt like a partner you could trust. Over the years we grew with them... [now leaving]"
Another: "Mailchimp used to be fantastic. It is gone totally downhill in recent years."
The post-Intuit acquisition quality decline is real.
Who Should Use Mailchimp?
Perfect for:
- Absolute beginners (under 500 contacts)
- Businesses needing 300+ integrations
- Agencies serving risk-averse clients
- Users who prioritize brand name over value
- Anyone wanting the easiest starting point
Real user story: "I just wanted to send a weekly newsletter to 200 people. Mailchimp free worked fine for that."
Who Should Avoid Mailchimp?
Run from:
- Anyone over 500 contacts (overage charges will hurt)
- Budget-conscious users (competitors are 50-70% cheaper)
- Users needing reliable automation (Essentials only has 4 steps)
- Anyone who has had billing issues before
- Businesses needing predictable pricing
The G2 vs Trustpilot Mystery
G2 rating: 4.3/5 (11,899 reviews) Trustpilot rating: 2.9/5 (1,297 reviews)
This is a massive gap.
Possible explanations:
- G2 reviews are more curated/incentivized
- Trustpilot captures raw user frustration
- G2 reviewers are using different features
- G2 reviewers are on different pricing tiers
The truth is probably in the middle. The product works (G2 4.3/5). The billing and support experience is frustrating (Trustpilot 2.9/5).
Mailchimp vs Alternatives
| Platform | Trustpilot | Free Tier | Paid Starts At | Best For |
|---|---|---|---|---|
| Mailchimp | 2.9/5 | 500 contacts | $13/month | Beginners |
| MailerLite | 4.4/5 | 500 contacts | $9/month | Budget users |
| Brevo | 4.2/5 | 300 emails/day | $9/month | Volume senders |
| ConvertKit | 2.0/5 | 10,000 subs | $39/month | Creators |
| GetResponse | 4.0/5 | Trial + limited | $41/month | All-in-one |
Notice: Every competitor has a better Trustpilot rating than Mailchimp.
Final Verdict
Mailchimp is not a bad platform. It is just overpriced for what you get.
The free plan is unusable for serious email marketing. The paid plans cost 2-3x more than competitors. The billing practices are aggressive. The support is difficult to reach.
If you are an absolute beginner with under 500 contacts, start with Mailchimp free.
But have an exit plan.
Once you cross 500 contacts, switch to:
- MailerLite (better value)
- Brevo (unlimited contacts option)
- ConvertKit (if you are a creator)
- ActiveCampaign (if you need automation power)
The 67% 1-star Trustpilot rating is a warning sign.
The long-time user exodus is real.
The post-Intuit quality decline is documented.
Mailchimp will work for you. But it will probably cost more than it should.
Start exploring alternatives before you outgrow the free plan.
Your accountant will thank you.
