Best Email Marketing Companies in 2026: 9 Companies Compared

Mailchimp remains the default recommendation for a reason: almost every store, form, and booking tool connects to it, and the builder is easy for a first-time user. Paid plans start at $13 per month for Essentials with 500 contacts, and $20 per month for Standard, which adds more automation flows and audiences. That breadth makes Mailchimp a safe choice when you are not sure what you will need next.

The cost curve is the catch. Because Mailchimp bills by contact count, a list that grows from 500 to 5,000 contacts moves Essentials to $75 per month and Standard to $100 per month. The free plan, at 250 contacts and 500 sends per month, is now a trial in practice rather than a long-term plan. Archive inactive contacts regularly, since unsubscribed contacts can still count toward your limit.

Klaviyo is built for stores, not general newsletters. It pulls purchase history, browsing behavior, and product data into segments, so you can send a different message to a first-time buyer, a repeat buyer, and a cart abandoner without manual lists. The free plan covers small lists, and paid email plans scale with contacts, with SMS billed separately.

For a store, that data focus often pays for itself through recovered carts and repeat orders. For a simple newsletter, Klaviyo is more tool than you need, and its price will feel high compared with MailerLite or Kit. Choose Klaviyo when revenue per email matters more than the monthly subscription.

ActiveCampaign suits teams that want email to do more than send a weekly newsletter. Its automation builder handles branching, tagging, lead scoring, and CRM tasks in one workflow, which helps service businesses follow up with leads over weeks rather than days. That depth is why agencies and growing service firms often choose it over simpler tools.

The downside is complexity. A beginner can send a campaign quickly, but building a good automation takes planning and testing. Pricing also depends on contact count and plan, so use the pricing calculator on the vendor site for your list size. If you only send a monthly newsletter, a simpler tool will be faster and cheaper.

Brevo, formerly Sendinblue, is attractive because it prices partly by email volume rather than only by contact count. That model helps a business with a large list that emails rarely, since you are not paying a high tier just to store contacts. The free plan allows a daily sending limit, and paid plans add more sends, automation, and landing pages.

The design experience is less polished than Mailchimp or Kit, and some advanced automation features require higher plans. For a budget-conscious business that also wants SMS, Brevo is a practical choice. For a design-led brand that lives in templates, look at Mailchimp or MailerLite first.

Kit, formerly ConvertKit, is made for writers, podcasters, and course creators. It keeps the focus on subscribers, sequences, and landing pages, without the store and CRM layers that complicate other platforms. The free plan covers up to 1,000 subscribers with basic sending, and paid plans add automation, reporting, and monetization tools.

The plain design is deliberate, since plain emails often perform well for newsletters, but brands that want rich visual templates may find Kit limiting. Kit also lacks the deep purchase automation of Klaviyo. For a creator building an audience and selling a course or paid newsletter, Kit hits the right balance.

MailerLite is our pick for a small business that wants low cost without a confusing interface. The builder is clean, automation covers welcome series and basic journeys, and the free plan supports up to 1,000 subscribers with a monthly send limit. Paid plans stay competitive as the list grows, which makes budgeting easier than on contact-heavy platforms.

New accounts go through an approval check, which can delay a first send, and the integration library is smaller than Mailchimp. Those are fair trade-offs for the price. If you send regular campaigns, want simple automation, and do not need a full CRM, MailerLite is hard to beat on value.

Constant Contact has long served local businesses, nonprofits, and event organizers, and its support is a real selling point. If you want a person to help you set up a campaign, Constant Contact is more hands-on than most rivals. Templates cover restaurants, salons, shops, and community groups, and event tools help with invitations and registrations.

The price reflects that support, and automation is simpler than ActiveCampaign or Klaviyo. For a business that emails a local list a few times a month and values help over advanced features, that trade is reasonable. For a store that needs purchase-driven flows, Klaviyo will do more.

HubSpot makes sense when email is part of a wider sales system. The free plan includes a CRM with unlimited contacts, up to 2,000 emails per month, forms, and live chat, which is generous for a business starting out. As you upgrade, email connects to deals, tickets, and workflows, so a lead that opens an email can move through your sales pipeline without manual work.

Paid Marketing Hub plans start higher than standalone email tools and rise with contacts and seats, so HubSpot is not the cheapest email-only choice. Choose HubSpot when you need CRM, sales, and service tools together. Choose a standalone email tool when you only need campaigns and automation.

GetResponse suits a business that sells through funnels and live sessions. Beyond email, you get landing pages, signup funnels, and webinars, which helps a course creator or coach run a launch without stitching together several tools. Automation templates cover welcome series, cart recovery, and webinar follow-up.

That breadth makes the dashboard busier than MailerLite, and webinar attendee limits vary by plan, so check the tier that fits your audience size. For a simple newsletter, GetResponse is more than you need. For a business built around launches and live teaching, the bundled tools can save money overall.
