Best Email Marketing Software for Small Businesses: Practical Picks Compared

The best email marketing software for small business sends good emails, grows your list, and stays cheap as you grow. Mailchimp, Brevo, Constant Contact, MailerLite, and Kit all serve small teams, but their pricing models are very different. This guide compares them on free plans, starting prices, and small-business fit.

Email marketing still works because you own the list. Social reach changes with each algorithm update. An email list stays yours. The right tool helps you send newsletters, welcome emails, and promotions without a big budget.

What small businesses need from the best email marketing software for small business

Small teams need five things. First, a free plan or cheap entry price. Second, easy templates and a drag-and-drop editor. Third, signup forms and landing pages. Fourth, basic automation like welcome emails. Fifth, pricing that scales with your list size.

Watch how each tool charges. Some charge by contacts. Others charge by emails sent. A tool that is cheap at 500 contacts can be costly at 5,000. Check the price at your size in one year, not just today.

Also check the free plan limits. A free plan with 250 contacts suits a new list. A free plan with 10,000 contacts suits a growing newsletter. The limit shapes your choice.

Prices come from each vendor's pricing page. Confirm the live price before you buy.

Mailchimp: the best-known starting point

Mailchimp's free plan costs $0 per month. It covers up to 250 contacts. It includes email support for the first 30 days. Paid plans start at $13 per month for Essentials and $20 per month for Standard.

Mailchimp is easy to learn. Its templates look good. Its store integrations are strong. That makes it a natural pick for small online shops.

The free plan is small, though. A list past 250 contacts needs a paid plan. Costs rise with list size. Check the price at 1,000 and 5,000 contacts before you commit.

Brevo: the best value for frequent senders

Brevo's free plan allows 300 emails per day. That adds up to about 9,000 emails per month. No credit card is needed. Paid plans start at $9 per month for 5,000 emails. Standard starts at $18 per month.

Brevo charges by emails sent, not by contacts stored. That is a big difference. A large list with low send volume stays cheap. Brevo also includes SMS, WhatsApp, and a built-in CRM.

Brevo fits small businesses that send often. Newsletters, order updates, and promotions all count toward the daily limit. At 300 emails a day, a small list runs free for a long time.

Constant Contact: the best for events and local business

Constant Contact has no free plan. It offers a 30-day free trial. Lite starts at $12 per month for 500 contacts. Standard starts at $35 per month. Premium starts at $80 per month.

Constant Contact is built for local businesses. It includes event management, social posting, and signup forms. Its editor is simple. Its support is strong.

The price rises with your contact count. At 500 contacts, Lite is $12 per month. At 5,000 contacts, Lite rises to $80 per month. That scaling matters. Compare it with Brevo's send-based pricing before you choose.

MailerLite: the best simple tool for creators

MailerLite's free plan costs $0 per month. It covers up to 250 active subscribers and 2,500 monthly emails. It includes up to 3 automations, 3 forms, 1 landing page, and 1 website.

Paid plans start at $12 per month for Comfort at 500 subscribers. Power starts at $25 per month. The free plan was updated in June 2026. Subscriber and sending limits fell from earlier levels, so older reviews may quote higher limits.

MailerLite fits creators and small teams that want a clean editor. It includes all three email editors on the free plan. It also includes digital product sales. For a simple newsletter, it is hard to beat.

Kit: the best free plan for growing newsletters

Kit, formerly ConvertKit, offers a free plan for up to 10,000 subscribers. It includes unlimited forms, unlimited landing pages, and unlimited email broadcasts. Paid plans are priced by subscriber count, not by emails sent.

That free plan is the most generous on this list by subscriber count. A creator can grow to 10,000 subscribers before paying. The free plan includes one email sequence and one basic automation.

Kit fits creators who write newsletters. It is less suited to stores that need deep ecommerce tools. If your goal is audience growth, Kit's free plan is the best deal here.

How to choose the best email marketing software for your small business

Follow these steps.

1. Count your contacts today and in one year.
2. Count how many emails you send each month.
3. Test the free plan or trial with a real campaign.
4. Check the price at your one-year list size.
5. Pick the editor your team finds easiest.

Match the pricing model to your habits. A big list with few sends fits Brevo. A small list with many sends fits a contact-based plan. A growing newsletter fits Kit's free plan.

Also test deliverability basics. Use a clear sender name. Keep your list clean. Send regularly. No tool fixes a stale list.

Bottom line

For most small businesses, Brevo is the best value. Its free plan sends 300 emails a day. Its paid plans start at $9 per month. For creators growing a newsletter, Kit wins on its free plan up to 10,000 subscribers. For beginners, Mailchimp is the easiest start. For simple newsletters, MailerLite is the cleanest tool. For events and local business, Constant Contact is the best fit. Pick the pricing model that matches your list, then test it with real emails.
