Best Email Marketing Software for Small Business in 2026
A small business wants its email sent without hiring a marketer. That means good templates, a simple editor, help when something goes wrong, and a bill that does not jump every time the list grows. Our first pick is Mailchimp: the safe default: it does what a small business usually needs and connects to the tools they already use. Brevo is the next to consider: pricing by emails sent keeps the cost low for a large list mailed occasionally.

02The Shortlist
Mailchimp
From$13/moValue score4.5/5
Why it’s here: The safe default: it does what a small business usually needs and connects to the tools they already use.
Mailchimp is the email tool most small businesses try first. It covers campaigns, templates, basic automation, landing pages and forms, and connects to almost everything. It is a generalist: good at getting a newsletter out, less convincing once you need advanced automation, and priced by the size of your audience.
- Best for
- SMBs that want a familiar general-purpose email platform
- Pricing
- Essentials plan, billed monthly, 500 contacts at this price. Free plan: 250 contacts and 500 sends a month.
- Key features
- Email campaigns and templates, Audience segmentation, Marketing automation journeys
Where it falls short: The price rises with every contact you add, the free plan is small, and automation is shallower than in specialist tools.
Brevo
From$8.08/moValue score4.7/5
Why it’s here: Pricing by emails sent keeps the cost low for a large list mailed occasionally.
Brevo, formerly Sendinblue, combines email campaigns with SMS, WhatsApp, transactional email and a light CRM. Its pricing is based on how many emails you send, not on how many contacts you store, which favors large lists that are mailed occasionally. The free plan caps daily sends instead of list size.
- Best for
- SMBs that want email, SMS, and transactional messaging in one tool
- Pricing
- Starter plan, billed annually ($9 billed monthly), from 5,000 emails per month. Free plan: 300 emails a day.
- Key features
- Email campaigns and automation, Transactional email, SMS marketing
Where it falls short: Templates and reporting are plainer than Mailchimp’s, and the free plan’s daily cap limits how many people you can reach at once.
MailerLite
From$10.80/moValue score4.6/5
Why it’s here: Covers the essentials for less money, with an editor that needs no training.
MailerLite is a simple, inexpensive email tool with a clean editor. Newsletters, landing pages, forms and straightforward automations are all there, and the free plan is usable. It leaves out the heavier features, which keeps both the interface and the bill small.
- Best for
- Small businesses and creators that want value and simplicity
- Pricing
- Comfort plan, billed annually ($12 billed monthly), 500 subscribers at this price. Free plan: up to 250 subscribers.
- Key features
- Newsletter builder, Automation workflows, Landing pages and websites
Where it falls short: Automation, reporting and integrations are lighter than in the bigger platforms.
Constant Contact
From$10.20/moValue score4.2/5
Why it’s here: Phone support and event tools suit owners who are not marketers.
Constant Contact is a long-standing choice for small businesses and nonprofits. Beyond email it handles event registration, social posting and surveys, and it backs them with phone support and plenty of guidance. Automation is basic, and there is a trial instead of a free plan.
- Best for
- Small businesses that want straightforward email marketing
- Pricing
- Lite plan, billed annually ($12 billed monthly), 500 contacts at this price.
- Key features
- Email templates and campaigns, Audience segmentation, Event marketing tools
Where it falls short: Automation and segmentation are limited, and you pay from the start.
ActiveCampaign
From$15/moValue score4.2/5
Why it’s here: For the small business ready to invest in automation.
ActiveCampaign is an automation tool that also sends email. Its visual builder handles branching logic, lead scoring, site tracking and conditional content, and a sales CRM can be added on. It asks for more learning than its simpler rivals and repays it for businesses whose marketing depends on timing and behavior.
- Best for
- Businesses that prioritize automation and segmentation
- Pricing
- Starter plan, billed annually ($19 billed monthly), 1,000 contacts at this price.
- Key features
- Advanced automations, Segmentation and personalization, Built-in CRM
Where it falls short: There is no free plan, the learning curve is real, and the cost climbs with both contacts and tier.
GetResponse
From$15.58/moValue score4.3/5
Why it’s here: Worth it if you also want landing pages and webinars.
GetResponse packs a lot around its email tool: automation, landing pages, sign-up funnels, webinars and a website builder. It suits marketers who want one subscription for lead generation and follow-up. Breadth is the appeal, and no single part is the best in its class.
- Best for
- Marketers who want email plus funnels and webinars
- Pricing
- Starter plan, billed annually ($19 billed monthly), 1,000 contacts at this price. Free plan: up to 500 contacts.
- Key features
- Email campaigns and autoresponders, Marketing automation, Conversion funnels
Where it falls short: The interface is crowded, and the more advanced automation and webinar features need the higher tiers.
AWeber
From$12.49/moValue score4.1/5
Why it’s here: A plain, dependable option with support you can call.
AWeber has been sending email for small businesses since the late 1990s. It offers templates, autoresponders, landing pages and sign-up forms, with phone support that many newer tools have dropped. It is dependable and plain, and its automation has not kept pace with younger competitors.
- Best for
- Small businesses that want straightforward newsletter sending
- Pricing
- Lite plan, billed annually ($15 billed monthly), 500 subscribers at this price.
- Key features
- Email templates and newsletters, Landing pages, Basic automations
Where it falls short: Automation and segmentation are basic, and the interface shows its age.
