Choose a customer journey, not only an email editor
Brevo and Mailchimp both cover campaigns, segmentation and automation, but the selection should not start with a template gallery. Start with data and the customer journey: where the contact enters, which system owns the profile, how consent is recorded, which events trigger communication and how results return to the CRM or online store. An attractive newsletter does not fix duplicate contacts, vague segments or absent follow-up.
For an SME, the costliest mistake is a prematurely complex stack. If you send two newsletters a month, do not build forty automation branches. If email is central to onboarding, retention and transactional messages, evaluate reliability, data model and ownership—not only the initial price. Design for the next eighteen months, but implement only journeys the team can maintain now.
Brevo and Mailchimp at a glance
| Criterion | Brevo | Mailchimp |
|---|---|---|
| Centre of gravity | Customer engagement across marketing, transactional and additional channels | Marketing platform for campaigns, audiences, segmentation, journeys and an extensive ecosystem |
| Strong starting point | Teams wanting marketing and transactional email in a closely connected environment | Teams wanting a familiar campaign workflow and mature marketing ecosystem |
| Contact data | Contacts, attributes, lists and automation events | Audiences, contacts, fields, tags, groups and segments |
| Automation | Workflows based on contact behaviour and events | Customer Journeys based on triggers, rules, tags and activity |
| Integrations | APIs, plugins and connections to CRM and commerce tools | Broad catalogue of commerce, CRM, forms and design integrations |
| Primary risk | Mixing marketing, sales and transactional data without ownership | Creating duplicate audiences and an opaque tag strategy |
A platform cannot repair a poor contact model. Define one profile, one consent history and clear segmentation rules first.
When Brevo is the more logical starting point
Brevo positions itself as a customer engagement platform spanning email, SMS, WhatsApp, transactional messaging, automation, CRM and other channels. That can suit a small team wanting marketing campaigns and operational messages—such as confirmations, reminders or password emails—in a connected environment. Keep marketing consent separate from the purpose of transactional messages and use appropriate templates, sending domains and controls for each stream.
A practical case is a service company with a lead form, sales follow-up and client onboarding. A new lead enters with source and consent, receives a welcome sequence and creates a CRM-owner task. After signing, the contact moves to a customer segment and receives operational instructions. Brevo is a reasonable candidate when this multichannel and transactional context matters more than advanced commerce analytics or a workflow deeply embedded in another marketing ecosystem.
When Mailchimp is the more logical starting point
Mailchimp is a strong starting point for teams wanting an established campaign process, templates, audience segmentation, Customer Journeys and a wide range of ready integrations. Tags can represent internal classification such as customer type or campaign source, while segments dynamically filter contacts from data and behaviour. The team must understand the distinction: a tag is a label; a segment is the output of rules.
A practical case is an e-commerce or content business using Shopify, WooCommerce, landing pages and behavioural campaigns. Mailchimp can support welcome, post-purchase and re-engagement journeys from available customer events. It is a logical choice when marketing is the centre, the team values the broader ecosystem and the planned integrations are officially supported. Confirm that each required capability is included in the current plan.
Compare total operating cost, not the entry plan
Pricing changes, and platforms may combine contacts, sending volume, users, features and additional channels differently. Build a twelve-month model using marketable contacts, actual monthly sends, automation volume, transactional email, SMS, seats and expected growth. Add one-off work for migration, templates, domain authentication, integrations and training.
Clean the database before calculating. Paying for inactive, duplicate or incorrectly classified contacts compares poor data hygiene rather than products. Define suppression, bounce, unsubscribe and retention rules. Never move people among lists by export and import without a stable contact ID and consent history.
Four automations an SME will actually use
Open rate is an increasingly uncertain signal because of privacy mechanisms and automated opens. Prefer clicks, form completion, purchases, bookings and replies when available and lawfully processed. Define an entry rule, exit rule, frequency cap, owner and test contact for every automation. Check whether a person can enter twice and what happens when their email address changes.
1. Welcome and qualification
Deliver the promised resource after valid signup, capture a preference and create a sales task only when a clear intent signal appears.
2. Lead nurture
Use three to five messages with one purpose each. Branch on a click or completed form rather than assumptions about the person.
3. Onboarding
After purchase or signature, send instructions, check that the key step happened and escalate missing completion to an owner.
4. Re-engagement
Define inactivity from a business event, not open rate alone. Offer a choice, reduce frequency and suppress inactive contacts under a stated rule.
A 90-minute scorecard and 30-day pilot
Use the same test-contact set to build a welcome journey in both platforms. Configure domain authentication from the official instructions, test unsubscribe and suppression behaviour, connect one real acquisition source and one conversion event. Ask the future system owner to make a change without help from a salesperson or consultant.
After thirty days, compare build time, successful delivery, segment quality, conversion data, errors and maintenance. Select one primary platform and document the reasoning. The answer must fit the customer journey, team skills and business architecture. The next step is not another campaign; it is stable data and two or three automations the team measures and improves every month.
