The question comes up constantly: Mailchimp or something else? The answer almost always depends on two things you need to get clear on first. What kind of emails are you sending, and how big is your list right now?

Those two questions narrow down the options faster than any feature comparison. Most small businesses are sending one of two types of email: a newsletter or promotional message to a list of people who signed up, or a transactional email like an order confirmation or a booking reminder that goes out automatically when something happens. The right platform for one is not always the right one for the other.

The Two Types of Email, and Why They Matter

Marketing email is the newsletter, the promotional campaign, the announcement. You write it, you design it, you schedule it. The platform's job is to make it look good, get it delivered, and tell you how many people opened it.

Transactional email is the automated kind: order confirmed, appointment reminder, password reset, shipping update. The platform's job is reliability. These emails have to land every time, fast, because a customer is waiting on them.

Most small businesses starting out only need a marketing email platform. Transactional email becomes relevant when you have a store, a booking system, or any automated process that sends customers a message after an action they took.

How the Main Options Stack Up

Brevo 300 sends/day, unlimited contacts Growing lists, both marketing and transactional, clean interface Daily send cap on free plan, not just monthly

What We Use and Why

At Balay ni Bruno & Co., we use Brevo for our own email campaigns and for the businesses we manage email for. The reason is simple: the free plan gives you 300 emails per day with no contact limit. For a growing list that is not yet at thousands of contacts, that is enough to run a consistent newsletter without paying anything yet.

When a business we work with is on Shopify and doing serious e-commerce volume, Klaviyo becomes the right answer because of how deeply it connects with the store's data. But for a service business, a local shop, or a studio just building its list, Brevo does the job at the price that makes sense at that stage.

One thing to do before you pick: estimate how many emails you will send in a month and how many people are on your list. If you are under 1,000 contacts sending one newsletter per week, every platform on this list has a free tier that covers you. Start free, grow into paid.

The Deliverability Question

Platform features matter less than deliverability, which means whether your email actually lands in the inbox versus the spam folder. All the platforms above have solid deliverability for legitimate businesses. The thing that hurts deliverability is not the platform you pick. It is sending to old lists with lots of bad addresses, buying contacts, or sending too much too fast.

When we set up email for a business, the first thing we do is clean the list: remove hard bounces, remove addresses that have never opened anything, and warm up the sending volume slowly. That habit matters more than which platform you are on.

What email platform should a small business use?

It depends on what you are sending. For a newsletter to a list of subscribers, Brevo, Mailchimp, or Klaviyo all work with a free tier to start. For transactional emails, a platform with reliable delivery focus matters more than design features. We use Brevo for our own business because of its generous free plan and clean interface.

Is Mailchimp still good for small businesses?

Mailchimp is easy to start with, but the price climbs quickly as your list grows and some features were removed from the free plan. For a small business starting its email list, it still works. For a growing list where cost matters, Brevo gives more sends per month at lower cost.

How many emails can I send for free?

Brevo: 300 per day, unlimited contacts. Mailchimp: 500 contacts, 1,000 per month. Klaviyo: 250 contacts, 500 per month. MailerLite: 1,000 contacts, 12,000 per month. For a small list getting started, all four are enough to begin without paying.

  • For most service businesses and small shops, Brevo or MailerLite covers the free-tier start
  • For Shopify stores, Klaviyo's deep integration is worth it at volume
