10 Best Email Marketing Software for Small Business of 2026

MailerLite fits the way most small businesses use email: a newsletter, a promotion now and then, and a welcome series for new signups. The free plan already handles all three, with campaigns, automations, signup forms, a landing page and a small website for up to 250 subscribers and 2,500 emails a month. That is enough for a new shop or studio to build the habit at no cost. Comfort starts at $12 a month and adds unlimited templates, dynamic emails, automatic resends to people who did not open, multivariate testing, an unsubscribe page builder, a preference center and an AI writing assistant. It also allows 50 automations, 10 forms and 3 user seats, which covers most small teams. Power, from $25 a month, removes those caps. The limits to watch are the 250 subscriber ceiling on Free and the seat count on Comfort if several people edit campaigns.

Brevo turns the usual pricing model around. Instead of charging for every contact you store, it charges for the emails you send, which suits a small business that has collected a large list from in-store signups or past orders but only emails it a few times a month. The free plan sends up to 300 emails a day, and Starter costs $9 a month for 5,000 emails and removes the Brevo logo. Standard, at $18 a month, adds click heatmaps, geography and device reports and a landing page. The editor is drag and drop with industry templates and an AI content generator, and segmentation can filter on website activity and campaign engagement. The tradeoffs are real: the daily cap on Free spreads a large send across several days, Starter allows one user, and the multichannel Professional plan jumps to $499 a month.

Mailchimp is the name many small business owners already know, and its plan ladder is easy to follow: a basic Free plan for lists under 250 contacts, then Essentials, Standard and Premium, each priced by contact count. Essentials and Standard both come with a 14-day trial. Standard is the plan Mailchimp recommends for growing businesses, with enhanced automation flows, custom-coded templates, popup forms and generative AI features. Premium adds multivariate testing, predictive segmentation, phone and priority support and personalized onboarding. The platform does a lot, so a business rarely has to switch tools as its marketing gets more ambitious. The catch for a budget-minded business is cost: plans are tied to contacts and Mailchimp notes that overages apply when limits are exceeded, so a growing list raises the bill faster than on volume-priced tools. Our pricing page check returned euros, so the US price is pending.

Constant Contact is built for owners who would rather call someone than read a help article. Every plan, including Lite, comes with live 1:1 onboarding and live phone and chat support, which is unusual at this price. Lite starts at $10.20 a month billed annually and covers the drag and drop editor, an AI copy generator, templates, signup forms and automatic posting to Facebook, Instagram and LinkedIn. Event hosting, product sales and payments are on every plan too. The limits show up in automation and targeting: Lite has one automation template and one custom segment. Standard, from $29.75, adds scheduling, subject line testing, three automation templates, resends to non-openers and ten segments. Premium, from $68, opens custom automations and unlimited segments. Prices depend on contacts and sends, and sends beyond the allowance cost $2 per 1,000.

Mailjet suits a small business that wants a simple, predictable bill and may also need to send receipts or account emails from its website. The free plan allows 6,000 emails a month to 1,000 contacts, with a 200 per day cap, and already includes APIs, SMTP relay, webhooks, the advanced editor and a form builder. Starter costs $9 a month for 8,000 emails and 2,000 contacts with no daily limit. Essential, at $19 a month for 15,000 emails, adds unlimited contacts, segmentation, AI-assisted content and removes the Mailjet logo. Premium, at $29 a month, is where automations, landing pages and advanced statistics appear. That split is the main drawback for marketers, since a welcome series needs the top self-serve plan. For a business that mostly sends newsletters and order emails, though, the entry prices are among the lowest here, and paying annually takes off 10%.

Zoho Campaigns has the most generous free plan on this list for contact count: 2,000 contacts, 6,000 emails a month and five users, with templates, the drag and drop editor, HTML import and generative AI. A small business with a few thousand customers can run a monthly newsletter for free for a long time. Standard, priced by contact tier from 500 contacts, removes the email cap and adds 10 users, basic segmentation, more than 120 templates, A/B testing, attachments and simple drag and drop workflows. Professional adds the tools a growing shop eventually wants, such as contact scoring, dynamic content, send time optimization, pop-up forms, RSS campaigns and abandoned cart workflows. It works best for businesses already using Zoho CRM or Zoho Books, and the pricing page offers a 25% discount for yearly billing. Our check of the page did not return a fixed US dollar figure, so the price is pending.

GetResponse prices by list size and does not count sends, starting at $19 a month for unlimited messages to 1,000 subscribers, with 18% off a 12-month plan. That suits a business that emails often, such as a shop running weekly promotions. Starter includes AI content generators, a welcome email series, one custom automation workflow, a landing page builder, signup forms and popups, and SMS marketing. Marketer adds unlimited workflows, advanced segmentation, abandoned cart recovery, sales funnels, promo codes and web push notifications. Creator layers on webinars, a website builder and a course creator. New accounts get 14 days of premium features, after which the account falls back to a free version with limits. The tool is broad, which also means more menus to learn than in MailerLite or Constant Contact, and the most useful ecommerce features sit on Marketer rather than Starter.

Kit is designed for people who sell their own expertise, so it fits consultants, coaches, writers and makers better than a typical retail shop. Its free plan is unusually large at up to 10,000 subscribers and includes unlimited landing pages and forms, unlimited broadcasts, tagging and segmentation, and the ability to sell digital products and subscriptions. That means a solo business can grow a sizable newsletter before paying anything. Creator starts at $33 a month billed yearly for 1,000 subscribers and adds unlimited visual automations and email sequences, polls, SMS marketing, RSS campaigns, removal of Kit branding and 24/7 email and chat support. Pro, from $66, adds engagement scoring, deliverability reporting, a referral system and unlimited users. The weak point for a budget is the jump from free to $33, which is the highest entry price on this list, so it works best for businesses that earn directly from their audience.

AWeber keeps things simple with two main plans. Lite, at $12.49 a month billed annually, covers one email list, three landing pages, three email automations, three users and one custom segment, with a monthly send allowance of ten times your subscriber maximum. Plus, at $19.99 a month billed annually, removes most of those caps with unlimited lists, landing pages, automations, segments and users, and adds priority 24/7 support, advanced reporting, sales tracking and removal of AWeber branding. Both start with a 14-day trial. For owners who do not want to build anything themselves, AWeber sells a Done For You service that sets up emails, landing pages and workflows in seven days. The Lite plan is fine for one newsletter list, but a business with separate lists for customers and leads will need Plus. Compared with MailerLite and Brevo, AWeber offers no permanent free plan.

Moosend puts its main marketing tools in one Pro plan rather than spreading them across tiers: unlimited email campaigns, marketing automation with prebuilt recipes, landing pages and subscription forms are all included. Pro is priced by contact count from 500 contacts up, and paying twice a year saves 15% while paying yearly saves 20%. Moosend+ lets you add transactional email, dedicated IPs, hosted files or audience discovery, and Enterprise bundles those with SSO and an account manager. For seasonal senders there is also a credits plan that charges per email rather than per month. The 30-day trial needs no credit card, but forms and landing pages cannot be published during it, so it is a test drive rather than a free plan. Our check of the pricing page did not return a fixed US dollar figure, so the starting price is pending.
