8 Best Newsletter Platforms for Small Business in 2026

EmailOctopus does one job and does it at a low price. There is no SMS channel, no CRM and no website builder to learn, so a small business can import a list, pick a template and send a first newsletter the same day. The free plan covers 2,500 subscribers and 10,000 emails a month, and Pro starts at $9 a month billed annually. A shop that only needs email gets the lowest paid step in this list with the least to learn.

The catch is that the same focus that makes setup fast also caps what the tool can grow into. Free-plan reports only last 30 days, and you get one form and one landing page until you pay.

MailerLite suits a small business that wants one account for email and a simple web presence. Comfort starts at $12 a month for up to 500 subscribers and adds a website builder, landing pages and digital product sales next to the email tools. The editor is clean, the templates look good without much work, and a new account starts with a 14-day premium trial. A shop can run its site and its newsletter from one login.

The catch is that the free plan shrank in June 2026 and is now small. It covers 250 subscribers and 2,500 emails a month, so a growing list hits the paid tier fast.

Buttondown is the smallest and simplest tool here, and that is its appeal for a small business that mostly writes. Basic costs $9 a month for up to 1,000 subscribers, $90 a year, and includes sending from your own domain, a hosted archive, tagging, analytics and RSS-to-email. The Markdown or rich-text editor keeps the focus on words, and paid subscriptions come with 0% platform take if the business ever charges readers.

The catch is the size of the free tier. One hundred subscribers is the smallest free cap in this list, so a growing list pays sooner here than anywhere else. Automations and custom-domain archives are paid add-ons, and there is no website builder, no commerce and no support phone line.

Kit is the pick for a small business that sells knowledge. The free Newsletter plan covers up to 10,000 subscribers with unlimited broadcasts, landing pages and forms, so a business can build a list and test paid demand before spending anything. Paid plans add sequences, visual automations and paid recommendations, and built-in commerce lets you sell digital products and courses from the same account.

The catch is the price jump when you do pay. Creator starts at $39 a month for up to 1,000 subscribers, $33 billed yearly, which is the highest paid start in this list. The free plan also limits automation to one basic automation, so a business that needs sequences will pay sooner than the 10,000-subscriber cap suggests.

beehiiv is the growth pick for a small business. The free plan covers 2,500 subscribers with unlimited sends, a website, a podcast and the recommendation network, which puts your publication in front of other beehiiv readers. Paid plans add the ad network, paid subscriptions at 0% platform take, automations and digital products, so one account covers growth, ads and sales.

The catch is the price step. Lite now costs $59 a month at 1,000 subscribers, $49 billed yearly, after the October 2026 price rise, and monetization features sit behind that paywall. The free plan also lost custom domains in the same change.

Substack is the free pick for a small business that wants readers to find it. Publishing is free no matter how many subscribers you have, with no send limit, and podcast and video hosting are included. Notes, recommendations and the app put your work in front of people who already read on Substack, which is the closest thing in this list to a built-in audience. Paid subscriptions, trials and coupons are a switch away.

The catch is the 10% cut and the fit. Substack keeps 10% of paid subscription revenue forever, with no tier that lowers it, so a business earning $1,000 a month hands over $100.

Flodesk is the design pick for a small business. The templates look good without much work, and the Everything plan at $54 a month adds paid newsletter subscriptions, unlimited checkouts, sales pages, payment plans and abandoned cart emails to the email core. A shop that sells through beautiful pages can run email, checkout and sales from one account, with unlimited sends on every paid plan.

The catch is the free tier and the price of selling. The free plan covers forms, landing pages and link-in-bio pages only and does not send email, so you cannot run a newsletter free here at all. Paid subscriptions need the top plan at $54 a month, while Lite at $25 and Pro at $28 do not include them.

Sendy is the cheapest long-run option for a business that can run its own server. The license costs $69 once per domain, and sending runs through your own Amazon SES account at about $0.10 per 1,000 emails. A weekly newsletter to 10,000 readers costs roughly $4 to $7 a month in SES fees plus hosting, against $59 to $139 a month on hosted tools at that size. There are no per-subscriber fees and no feature tiers.

The catch is the work. Sendy is self-hosted commercial software, not open source, and you install it on PHP hosting, keep it updated, set up its scheduled jobs and watch deliverability yourself. There is no free plan, no phone support and no website builder.
