Choose Mailchimp if unsubscribe reasons are a must-have report. Choose Brevo if you want a cheaper email tool and can live with a more DIY reason-tracking setup.
TLDR: Mailchimp is better for collecting newsletter unsubscribe reasons because the survey is more visible and easier to read in reports. Brevo is solid for managing unsubscribes, but reason collection can feel more manual. For example, if 1,000 people get your newsletter and 25 unsubscribe, Mailchimp can help you spot that 40% left because emails came too often. In Brevo, you may need a custom form or workaround to get the same clean answer.
The short version
People unsubscribe. It stings. Then you stare at the number and wonder, “Was it me? Was it the subject line? Was it the third email about socks this week?”
This is where unsubscribe reasons help. They turn a sad click into useful feedback.
Mailchimp and Brevo both handle unsubscribes. No surprise there. The real question is different:
Which one helps you understand why people leave?
The answer is mostly Mailchimp. It gives you a more direct path to unsubscribe feedback. Brevo can still do it, but it may ask you to set up extra pieces.
Why unsubscribe reasons matter
An unsubscribe is not always bad. Really.
Sometimes it means your list is cleaning itself. A person is no longer interested. Fine. Better than paying to email someone who never opens.
But if many people leave for the same reason, you need to know fast.
- “Too many emails” means your sending schedule is annoying people.
- “Content is not relevant” means your targeting needs work.
- “I never signed up” means you may have a list quality problem.
- “I only joined for a discount” means your welcome flow may need better filtering.
Without reasons, you only see the exit door. With reasons, you see the sign above it.
Mailchimp: better built-in feedback
Mailchimp has a familiar unsubscribe flow. A contact clicks the unsubscribe link. They confirm. Then they can give a reason.
That is the key benefit. The reason survey is part of the normal experience. You do not need to build a strange little feedback machine from scratch.
Mailchimp can show common reasons like:
- Emails are too frequent
- Content is not relevant
- They did not sign up
- They no longer want the emails
- Other reason
The nice part is that these reasons can be tied back to your email performance. You can compare campaigns. You can look for patterns. You can stop guessing.
Honestly, it feels like this is exactly what an email tool should do. Someone leaves. Ask why. Show the answer. Done.
Where Mailchimp gets annoying
Mailchimp is not perfect. Let’s not pretend.
The interface can feel busy. Simple tasks sometimes hide behind too many menus. If you only want a quick answer, it can take longer than it should.
Also, Mailchimp pricing can jump as your list grows. That hurts small teams. You may start with a small newsletter and then suddenly think, “Wait, why is this bill wearing a tuxedo?”
Still, for unsubscribe reason tracking, Mailchimp is usually the easier pick.
Brevo: good email tool, weaker reason tracking
Brevo is a strong email marketing platform. It is often cheaper than Mailchimp. It also has good automation, transactional email, SMS options, and contact management.
But for collecting unsubscribe reasons, Brevo is less smooth.
Brevo handles unsubscribe links and suppression lists well. That part is not the issue. The issue is the “why.” If you want clear reason data, you may need to create a custom process.
For example, you might send unsubscribers to a custom page with a short form. That form can ask:
- Why are you leaving?
- Did we email too often?
- Was the content useful?
- Would you prefer fewer emails?
Then you can store those answers in contact attributes or export them into a spreadsheet. It works. But it is not as neat.
The catch is, you may spend 20 minutes building what Mailchimp gives you in a clearer format. That is not tragic. It is just irritating.
Mailchimp vs Brevo at a glance
| Feature | Mailchimp | Brevo |
|---|---|---|
| Built-in unsubscribe reason survey | Stronger and easier to use | More limited or more manual |
| Reporting on reasons | Clearer for most teams | May need custom tracking |
| Custom unsubscribe page | Available, with form options | Available, but reason tracking may need setup |
| Ease for beginners | Better for feedback data | Good overall, less direct here |
| Cost feel | Can get pricey | Often more budget-friendly |
A simple user case
Picture a small skincare brand called Glow Jar. They send a weekly newsletter to 12,000 subscribers.
In March, 318 people unsubscribe. That is a 2.65% unsubscribe rate. Ouch.
With Mailchimp, Glow Jar checks unsubscribe reasons and sees this:
- 46% say emails are too frequent
- 22% say offers are not relevant
- 15% say they only wanted the first-order coupon
- 17% choose other
That is useful. The team cuts emails from three per week to two. They also splits buyers and non-buyers into different groups.
In April, unsubscribes drop to 171. That is not magic. It is feedback doing its job.
With Brevo, Glow Jar could get the same insight. But they may need to build a reason form and connect the answers to their contacts. That is fine for a technical team. It is less fun for a founder eating lunch over a keyboard.
Which one is better for non-technical users?
Mailchimp wins.
If your team wants to open a report and understand why people left, Mailchimp is easier. It is built more clearly around campaign feedback.
Brevo is better if you like flexibility and lower costs. But flexibility can become extra work. You may need to plan the unsubscribe path yourself.
That means asking questions like:
- Where does the unsubscribe link send people?
- Is there a feedback form?
- Where are answers stored?
- Can you connect reasons to a campaign?
- Can your team read the results without crying into a spreadsheet?
Best practice: keep the survey tiny
Do not ask unsubscribers to write an essay. They are leaving. Respect the exit.
Use one question. Maybe two.
A strong unsubscribe survey can be this simple:
- Too many emails
- Content is not useful
- I only signed up for a discount
- I did not sign up
- Other
Add an optional text box if you want. But do not force it.
Also, give people an option to reduce email frequency. Some subscribers do not want to break up. They just want space.
A link like “Send me monthly updates instead” can save contacts. It is a soft landing. Much better than a hard goodbye.
When Brevo makes sense
Pick Brevo if price matters more than built-in unsubscribe reason reports.
It is also a smart choice if you already use Brevo for automation, transactional emails, or SMS. One tool can be easier than running three separate systems.
Brevo also works well if you have someone who can build custom forms and track data cleanly. In that case, the unsubscribe reason gap is not a huge problem.
But if your team is small, busy, and allergic to extra setup, Mailchimp will feel simpler.
Final verdict
Mailchimp is the better choice for collecting newsletter unsubscribe reasons. It is more direct. The feedback is easier to find. The reports are more useful for quick decisions.
Brevo is better for cost-conscious teams that do not mind building a custom feedback flow. It can still collect unsubscribe reasons, but it may take more setup and care.
If unsubscribe feedback is central to your email strategy, pick Mailchimp. If budget and broader email tools matter more, pick Brevo and plan your tracking in advance.
Either way, do not ignore the people leaving. They may be walking out, but they are also handing you the note that explains why.
