Brevo is usually better for simple, clear unsubscribe messages, while Mailchimp is better if you want polished templates, brand control, and built-in audience tools. If your main goal is to write a clean unsubscribe email that keeps complaints low, Brevo gets you there with less fuss. If you want more control over wording, design, segmentation, and a preference center, Mailchimp gives you more room to work.
TLDR: Pick Brevo if you want a fast, plain, low-friction unsubscribe message. Pick Mailchimp if you care about brand tone, design, and audience management after someone opts out. For example, a SaaS team with 25,000 contacts could reduce spam complaints from 0.16% to 0.07% by replacing a vague “manage your email” link with a clear “unsubscribe from product updates” message and a short preference option. Both tools can do this, but Mailchimp gives more editing depth, while Brevo is easier to set up quickly.

What an unsubscribe message actually needs to do
An unsubscribe message has one job: help people leave without confusion. That may sound negative, but it protects your sender reputation. A person who cannot find the unsubscribe link may hit “Report spam” instead. That hurts deliverability for everyone who still wants your emails.
A strong unsubscribe email or unsubscribe section should include:
- A clear unsubscribe link that is easy to spot.
- Plain wording, not tricks or guilt.
- Preference options, such as weekly updates instead of daily emails.
- A short confirmation after the action is complete.
- Brand tone that still feels respectful.
That last point matters more than many teams admit. The unsubscribe moment is still a brand touchpoint. A clunky message can make your company feel careless. A clean one leaves the door open for someone to return later.
Mailchimp: stronger control for branded unsubscribe experiences
Mailchimp is built for marketers who want control over every public-facing detail. That includes the footer unsubscribe link, update profile links, audience preferences, and automated confirmations.
Mailchimp lets you edit signup forms, profile update pages, unsubscribe confirmation pages, and final goodbye emails. This is useful if your brand voice is specific. You can write something warm, simple, or playful without sounding like a legal notice.
For example, instead of a cold line like:
“You have been removed from this mailing list.”
You might write:
“You’re unsubscribed from our weekly product tips. No hard feelings. If you still want release notes or billing alerts, you can update your preferences below.”
That is better. It confirms the action. It lowers anxiety. It gives the user a choice without blocking the exit.
Where Mailchimp shines
- Preference centers: Users can choose which email types they still want.
- Audience segmentation: You can separate product updates, events, offers, and newsletters.
- Template polish: Messages can match your normal email design.
- Reporting: You can track unsubscribes by campaign and spot problem content.
The reporting is especially helpful. If one campaign gets a 0.9% unsubscribe rate while your usual rate is 0.2%, something was off. Maybe the offer was irrelevant. Maybe the subject line overpromised. Maybe you sent too often. Mailchimp makes those patterns easier to see.
The annoying part? Mailchimp’s form and audience settings can feel scattered. Expect to click through several screens just to edit copy that feels like it should be in one obvious place. It is not terrible, but it can take a few extra minutes when you only want to change one sentence.
Brevo: faster setup and simpler unsubscribe copy
Brevo, formerly Sendinblue, is often easier for practical teams that want to send campaigns without wrestling with too many design settings. Its unsubscribe tools are clear, direct, and good enough for many small businesses, ecommerce brands, agencies, and B2B senders.
Brevo includes unsubscribe links in campaigns and supports list-based opt-outs. You can create unsubscribe pages and manage contact preferences. The writing experience is less ornate than Mailchimp, but that can be a benefit. Fewer options often mean fewer ways to overcomplicate the message.
A solid Brevo unsubscribe confirmation might say:
“You have been unsubscribed from our monthly newsletter. You may still receive account or transaction emails related to active services.”
That is short and useful. It also prevents a common misunderstanding. People may unsubscribe from marketing but still receive receipts, password resets, shipping alerts, or account notices.
Where Brevo works well
- Quick setup: Good for teams that need unsubscribe links working fast.
- Simple list management: Useful when you have fewer email categories.
- Transactional clarity: Brevo is strong when marketing and transactional email live close together.
- Lower complexity: Less time spent styling small details.
Honestly, it feels like Brevo respects the fact that many users do not want a giant project just to write “you’re unsubscribed.” That said, if you want every page to feel deeply branded, Brevo can feel a bit plain compared with Mailchimp.
Writing style: what to say in the unsubscribe message
The tool matters, but the copy matters more. Bad unsubscribe wording creates friction. Worse, it can look manipulative.
Avoid lines like:
- “Are you sure you want to leave us forever?”
- “You will miss out on exclusive opportunities.”
- “Please tell us why before we let you go.”
These sound needy. They also slow the user down. That is risky from a compliance and trust angle.
Use wording like:
- “Unsubscribe from weekly offers.”
- “You are now unsubscribed from product news.”
- “Want fewer emails instead? Choose monthly updates.”
This type of copy is clear. It speaks like a normal person. It gives options without hiding the exit.
Mailchimp vs Brevo: side-by-side comparison
| Feature | Mailchimp | Brevo |
|---|---|---|
| Best for | Branded unsubscribe flows and detailed audience control | Simple unsubscribe setup and practical list management |
| Ease of writing copy | Flexible, but settings can feel split across areas | Direct and quick, with fewer distractions |
| Preference center | Stronger for detailed choices | Good for basic preferences |
| Design control | Better for polished brand styling | Simpler and more functional |
| Reporting | Strong campaign unsubscribe insights | Useful core reporting |
Which one should you choose?
Choose Mailchimp if you send many campaign types and need users to pick what they receive. It is also the better pick when design matters. A media company, course creator, nonprofit, or lifestyle brand may prefer Mailchimp because the unsubscribe flow can still feel on-brand.
Choose Brevo if your unsubscribe needs are simple. It is a strong pick for service businesses, SaaS startups, ecommerce stores, and teams that want to separate marketing email from transactional messages without getting buried in settings.
Here is a practical rule: if you have three or more email categories, Mailchimp may be worth the extra setup. If you send one newsletter and a few promotions each month, Brevo will likely feel cleaner.
Best unsubscribe email example
Use this structure in either tool:
Subject: You’re unsubscribed
Message:
You have been unsubscribed from our weekly marketing emails. You may still receive account, billing, or service messages if they apply to you.
If you unsubscribed by mistake, you can update your email preferences here.
Thanks for reading while you were with us.
This message works because it is short, honest, and calm. It does not beg. It does not hide the action. It also explains why some emails may still arrive.
Final verdict
Mailchimp is the better choice for polished unsubscribe experiences. It gives you more control over tone, preferences, design, and reporting. Brevo is the better choice for speed and simplicity. It helps you write a clear unsubscribe message without turning the task into a mini campaign build.
If you are unsure, start with this question: Do users need choices, or do they just need a clean exit? If they need choices, use Mailchimp. If they need a clean exit, Brevo is more than enough.
