Constant Contact Alternatives in 2026

Mailchimp is the most straightforward replacement for most small businesses. Its free plan lets a new sender start without paying, and its paid Essentials plan starts at $13 per month for 500 contacts on monthly billing. Almost every other tool, store platform and form builder connects to Mailchimp, which makes migration and future integrations less painful.

The limits deserve a clear look. The free plan caps contacts and sends, and costs climb as your list grows, so a business with a large but quiet list may pay more than it expects. Automation depth also improves on higher plans. Even with those caveats, Mailchimp remains the safest default switch for a small business that wants a well-known tool with plenty of help available.

Brevo, formerly Sendinblue, is the best value pick for businesses with a large list that does not email every contact every week. Because it prices by how many emails you send, not how many contacts you store, a list of 10,000 quiet subscribers costs far less than on a contact-priced tool. Its paid plan starts at $9 per month, and the free plan allows 300 sends a day.

The free plan will not suit a business that sends a large campaign in one day, since the daily cap will force you to split sends. SMS and WhatsApp add useful reach, though they cost extra. For nonprofits and small businesses with big lists and modest sending, Brevo is often the cheapest honest option.

MailerLite appeals to senders who want a tidy editor and a fair price without a steep learning curve. Its free plan covers small lists, and its paid plans stay competitive for growing businesses. Landing pages, signup forms and basic automation are included, so a small team can run a newsletter and a simple welcome sequence from one place.

It is not the deepest automation tool here. Teams that need complex branching, lead scoring and CRM-style workflows will outgrow it sooner. New accounts can also face approval checks that delay the first send. For straightforward newsletters and small business campaigns, MailerLite is a calm, budget-friendly choice.

ActiveCampaign is the pick when simple newsletters are no longer enough. Its automation builder handles multi-step sequences, branching based on behavior, lead scoring and CRM tasks in a way that simpler tools cannot match. The Starter plan starts at $15 per month for 1,000 contacts on annual billing in recent reports, which is fair for the depth on offer.

The cost is time as well as money. Building good automations takes planning, and a small team that only sends a monthly newsletter will not use most of what it pays for. There is no free plan, only a trial. Choose ActiveCampaign when automation will genuinely earn its keep, such as welcome series, abandoned cart flows and lead nurturing.

Klaviyo is built for online stores, and that focus shows in its flows. Abandoned cart, post-purchase, browse abandonment and win-back sequences connect directly to store data, so messages can reflect what a customer actually bought or viewed. Its free plan covers small stores, and paid pricing scales with profiles and sends, so we have used See website for the current starting figure.

For a business that does not sell online, Klaviyo is overkill and often more expensive than a general email tool. Store owners should also watch profile counts, since all emailable profiles can count toward billing. When revenue comes from a store, though, Klaviyo often pays for itself through flows that general tools cannot match.

Omnisend gives store owners much of Klaviyo's practical value at a lower starting price. Its paid plan starts at $16 per month, and it includes prebuilt automation for welcome, cart recovery and post-purchase messages, plus SMS and push channels. That combination suits small stores that want automation without enterprise pricing.

The free plan is useful for testing, but its contact and send limits mean a growing store will move to paid plans fairly soon. Businesses without a store will find less to love here than in Mailchimp or MailerLite. For a small online shop on a budget, Omnisend is the balanced middle choice.

Kit, formerly ConvertKit, is built for creators, writers and newsletter publishers rather than general business marketing. Its free plan covers up to 10,000 subscribers in recent reports, which is unusually generous, and its sequences, forms and landing pages are designed for growing an audience. Paid plans add automation and commerce features as a creator's income grows.

Design flexibility is the trade-off. Templates are clean but simpler than the polished layouts in Mailchimp or MailerLite, and complex business workflows are not its strength. For a creator, coach or newsletter writer moving from Constant Contact, Kit is a natural fit, especially while the audience is still growing.

HubSpot suits businesses that want email beside a real CRM, not just a mailing list. The free tools cover contacts, forms and basic email, which is enough for a small business starting to organize leads. As the business grows, paid Marketing Hub plans add automation, landing pages and reporting, all tied to the same contact records.

The catch is the price curve. Paid plans, especially at Pro level, cost far more than the tools above, and a small team can feel lost in a platform built for larger companies. Start with the free CRM if you need sales and marketing in one place, and only upgrade when the CRM data is already part of your daily work.
