Brevo Alternative for Shopify: Unbundle Before You Switch

Keaz cover: unbundling a Brevo alternative into the four jobs the subscription was doing

In short

Brevo bundles email, SMS, chat and automation. Before you shortlist an alternative, work out which of those jobs is actually failing — and replace only that.

A Brevo subscription is sold as one product, but it does four separable jobs: it sends email campaigns, it runs automated sequences, it sends SMS, and it puts a chat widget on your storefront. That is why searching for a Brevo alternative usually produces the wrong answer. Name the four jobs, score each one, and in most stores you will find that one of them is failing and three are fine — which is a far cheaper problem to solve than a migration.

In short

  • Split the subscription into four jobs. Email campaigns, automated sequences, SMS, on-site chat. Score each from 0 to 2 on how much revenue it carries and how badly it works. Twenty minutes, your own data, no demo.
  • Usually one job is the problem. If three of the four score fine, replacing the suite means rebuilding three things that already work — and re-earning the consent behind them.
  • Consent does not travel with you. Meta requires an opt-in that names your business before you message anyone on WhatsApp, and no import creates one (Meta, retrieved 2026-09-22).

What four jobs is a Brevo subscription actually doing?

One line on the invoice, four jobs behind it. Naming them is most of the exercise, because a replacement search treats the suite as a single thing and the four jobs almost never fail together.

  1. Email campaigns. Newsletters and one-off sends to a list you own. This is the job most people mean when they say email tool, and it is the one most often working fine.
  2. Automated sequences. Messages that go out because something happened — an order, an abandoned checkout, a date passing — rather than because a person pressed send. This is where revenue per contact is usually decided.
  3. SMS. A second outbound channel with its own consent record, its own per-message cost and its own delivery rules. Many stores pay for this job and barely use it.
  4. On-site chat. A widget that catches questions before they turn into abandoned carts, plus the inbox behind it that someone has to answer.

Score each job twice, from 0 to 2: how much revenue does it carry, and how badly is it working? The job scoring 2 on revenue and 0 on working is the one you are actually shopping for. If you would rather start from hard figures than from a judgement, the four numbers in our walk-through of how to evaluate an email-tool replacement come straight out of the Shopify admin and take about an hour.

Which of the four is actually failing?

Scores in hand, most stores land in one of three situations. Each has a different remedy, and only one of them is a replacement.

  • The bill grew faster than the programme. Suite pricing scales with contacts and sends, not with what you use. If two of the four jobs score 0 on revenue, the cheapest fix is to stop paying for those two — not to move the two that earn.
  • A job is missing rather than broken. Automated sequences score 0 on revenue because nothing is running, not because the wrong thing is running them. Build the sequences where you already are; no migration writes them for you.
  • The problem is reach, not tooling. A share of your customers has a valid address and has not opened anything in a year. Every email tool inherits that share unchanged, because the people you are missing are not reading email at all. That is a case for a second channel, and we set the two side by side in WhatsApp versus email for e-commerce.

Only a fourth case is a genuine replacement search: the tool does not fit how your team works day to day, and no amount of measurement changes that. It is real, and it is rarer than the search volume suggests.

What does a suite migration actually cost?

The subscription is the line item. The cost is four things that do not come across with the contacts, and none of them appears in a pricing comparison.

  • Consent records. Not a yes/no flag but the level, the date and the source, per contact and per channel. Whatever you move to has to store it at a granularity you can filter a send on — the way opt-in levels work in Keaz, where a flow can require a minimum level before anyone enters it.
  • Automation logic. Every sequence has to be rebuilt, re-tested and watched for a month. Budget the watching, not just the building.
  • Attribution history. Your old numbers are the baseline you would judge the new tool against. Switch mid-year and you lose the comparison at exactly the moment you need it.
  • Sending reputation. A new setup starts without history and has to earn it back. Plan a warm-up rather than a cut-over.

Consent is the one that surprises people, because it does not transfer between channels either. Meta requires an opt-in before a business messages someone on WhatsApp; the permission may be general rather than WhatsApp-specific, but it has to name the business and comply with local law (Meta, retrieved 2026-09-22). An email or SMS list is not a WhatsApp list, and no import turns it into one. The cheapest bridge is to ask the subscribers you already have to start the conversation themselves, which works from whichever email tool you are already sending from.

How do you test a replacement without migrating first?

Run the candidate next to what you have, on the one job that scored badly, and let attributed revenue decide. Four steps.

  1. Pick one job, not the suite. Testing everything at once means you cannot tell which change moved the number.
  2. Give every message its own attribution. Per message, not per channel. A channel total cannot separate the one send that pays for the programme from the four that dilute it, so it cannot settle a comparison either.
  3. Run both for a quarter. A month flatters whichever one is new. A quarter covers a full re-order cycle for most stores.
  4. Decide on two columns of numbers. Not on the demo, and not on the feature list you wrote before you had the numbers.

If the job that scored badly is reach, the parallel test is a second channel rather than a second email tool, and the criteria we hold ourselves to are laid out in the features overview. Apply the same scepticism to any forecast a vendor shows you, including ours — the assumptions behind it are documented end to end so you can check them rather than take the number.

Common mistakes

  • Replacing four jobs to fix one. The most common and the most expensive. Three working things get rebuilt so that one broken thing can be swapped.
  • Shortlisting before scoring. Demos are persuasive and your scores are not. Take the scores into the demo, not the other way round.
  • Comparing on feature counts. Everything in this category can send a message. The differences are in what triggers it, who you may lawfully reach, and what you can prove afterwards.
  • Treating consent for one channel as consent for another. It is not, and the record you keep today is the one you will be asked for later. Collect each opt-in explicitly and store the level per contact.
  • Migrating in the fourth quarter. Moving a programme during your busiest trading weeks turns small breakages into lost revenue. Move in a quiet month or wait.
  • Sending to everyone on day one of a new channel. Limits start low and rise with quality. A large first send is the fastest route to a quality problem that costs weeks to unwind.

A Brevo alternative is the right search only when the scoring says the tool is the problem. More often it says something narrower: that one of the four jobs is carrying no revenue, or that nothing automated is running, or that a large part of the customer base cannot be reached by email at all. Those are answered by dropping a job, building a sequence, or adding a channel — none of which requires moving a list.

If reach is the job that scored worst, start by sizing it. Find out how much of your customer base you could reach on WhatsApp today and what that is worth per month. Calculate your forecast — a few minutes, on your own Shopify data, no code.

This article is a summary rather than legal advice. Consent requirements differ by market and by how you collect them, so have your own counsel review your opt-in flow before you rely on it.

Frequently asked questions

Is Keaz a Brevo alternative?
No, and it is more useful to say so plainly. Keaz is a WhatsApp marketing tool for Shopify stores; it does not send email campaigns and it will not replace an email programme. If your scoring says the failing job is reach — customers you hold addresses for who no longer open anything — Keaz addresses that job alongside whatever you send email with. If the failing job is email itself, you need an email shortlist, and this is not one.
Can I move my existing contacts to WhatsApp when I switch?
Not by importing them. Consent for email or SMS is not consent for WhatsApp, and Meta requires an opt-in that names your business before you message anyone (Meta, retrieved 2026-09-22). The working route is to ask your existing subscribers to start the conversation themselves, usually with a link or QR code in one email, and to let a flow collect the confirmation.
Should I replace the SMS job with WhatsApp?
Measure before deciding. The question is what share of your customer base you can lawfully reach on each channel, and that varies by market rather than by tool. If SMS scores 0 on revenue in your four-job scoring, the first move is to stop paying for it, not to swap it for something else.
How long should a parallel trial run before I decide?
A quarter. A month flatters whichever tool is new, because someone is watching it closely and nobody is watching the old one. A quarter also covers a full re-order cycle for most stores, so the comparison includes repeat purchases rather than only first orders.
What if only the price is the problem?
Then the question is which jobs you are paying for and not using. Suite pricing scales with contacts and sends regardless of how many of the four jobs you run, so dropping an unused job often costs less than a migration and carries none of the rebuild risk.
