Choosing between Constant Contact and ConvertKit (now called Kit) is one of the more lopsided comparisons in email marketing — not because one is better, but because they’re barely aiming at the same person. One is built around a local business with a storefront and an events calendar; the other is built around a writer or course creator whose whole business is the email list. Pick the one whose intended owner isn’t you, and you’ll spend months fighting the tool’s instincts.

Put simply: Constant Contact is the support-and-events small-business veteran — dependable, built for small businesses and nonprofits, with friendly phone support and built-in event invitations. Kit (ConvertKit) is the creator audience engine — visual automation, subscriber tagging, plain-text emails that read like a personal note, and built-in tools to sell and grow an audience. Get the match right and the choice nearly makes itself.

Honest disclosure: some links below are affiliate links. If you sign up through one I may earn a commission at no extra cost to you. Neither Constant Contact nor ConvertKit is one of them, so I have no stake in which of the two you pick — everything here is my genuine assessment, including where each falls short and where a different option might serve you better.

Pricing, free-plan terms and features change often on both platforms. Treat the specifics below as the shape of the trade-off, and confirm the current numbers on each provider’s pricing page before you decide.

The core difference in one sentence

Constant Contact is the dependable, support-first email veteran — built around small businesses, nonprofits and local organisations, with genuinely good human support (phone included) and built-in event invitations few rivals offer. Kit (ConvertKit) is the creator-focused audience engine — built around newsletter writers and course creators, with visual tag-based automation, deliberately plain emails, built-in selling of digital products, and a recommendation network designed to grow your list.

The fastest way to feel the difference: finish this sentence — “My email list exists so that I can ___.” If the blank is promote my local business and run my next event, you’re probably a Constant Contact person. If it’s grow an audience and sell what I create to it, you’re probably a Kit person.

Constant Contact: the support-and-events veteran

Constant Contact is one of the oldest names in email marketing — a long-running, dependable platform built for small businesses, nonprofits and local organisations. Its calling card isn’t a flashy feature; it’s reliability, support and a couple of things rivals quietly skip.

Pros:

• Human support, including phone. This is Constant Contact’s standout. Responsive support — phone, chat and email — is genuinely rare in this market and a big deal if you’re a beginner or a busy small-business owner who wants to talk to someone.
• Built-in event management. Event invitations and registration are one of its more distinctive features; most email tools don’t include them natively, so if you run live events this alone can justify it.
• Dependable, small-business-shaped email. Broadcasts, signup forms, basic automation, a long deliverability track record, and tooling (plus nonprofit discounts) aimed squarely at local organisations.

Cons:

• The interface and automation feel dated next to a creator-modern tool, and the automation is light — you’ll hit its ceiling sooner if you want real tag-based, branching sequences.
• Contact-based pricing climbs as your list grows, and many people find it expensive for what is, at heart, fairly basic email.
• Only a free trial, not a permanent free plan, so there’s no genuinely free tier to grow on.
• Email-first, so no creator commerce built around the list and no real sales funnels or course hosting — you’ll bolt extra tools on to sell.

Kit (ConvertKit): the creator audience engine

Kit — the tool most people still know as ConvertKit — is built from a different premise: that the email list isn’t a marketing channel bolted onto a business, it is the business. Everything is shaped around a creator growing and monetising an audience.

Pros:

• Creator-grade automation and segmentation. Visual automation sequences, subscriber tagging and segmentation are Kit’s heart — you can branch on what someone clicked, bought or signed up for, which makes nurturing an audience genuinely powerful compared with Constant Contact’s lighter automation.
• Sell straight to your list. Kit lets you sell digital products and paid newsletters right next to your subscribers, so a creator can earn from the list without stitching on a separate store.
• A list-growth engine. Its recommendation network can actively put your newsletter in front of new subscribers — something neither Constant Contact nor most rivals offer. Plain, text-style emails (Kit’s philosophy is that simple emails feel personal and convert better) and a free tier to start round it out.

Cons:

• Deliberately plain templates. If you want glossy, image-heavy designs, Kit’s text-first aesthetic can feel bare — by design, but not to everyone’s taste.
• Premium-priced as you grow, and it bills by subscriber count and climbs; the free plan limits the automation and commerce features that are the actual reason to choose Kit.
• No phone support and no event management — it’s self-serve, and it isn’t built for the local-business-and-events world Constant Contact serves.
• Still email-first — built-in product sales help, but there are no multi-step funnels with order bumps and upsells and no full course platform with memberships.

Head to head on what actually matters

Pricing model

Both bill by contact count, and both climb. Neither uses the send-based pricing that makes a big-but-rarely-emailed list cheap (that’s Brevo’s trick). The starting point differs: Kit has a free tier, while Constant Contact offers only a free trial — so Kit is cheaper to start. As your list grows, both get more expensive, and Kit is often called premium once you want its automation and commerce unlocked, while Constant Contact’s nonprofit discounts can lower its bill if you qualify. Edge: Kit to start free — but verify both against your contact count, because the numbers shift often.

Support

No contest. Constant Contact offers responsive human support to its customers, phone included; Kit’s support is self-serve, with no phone reassurance. If “I want to be able to call someone” is on your list, this single difference may decide it. Edge: Constant Contact, clearly.

Events

Constant Contact has built-in event invitations and registration — a genuinely distinctive feature. Kit has nothing comparable natively. If live events are part of your business, this is close to a deal-maker. Edge: Constant Contact.

Automation and segmentation

Kit is the stronger tool here, and it isn’t especially close. Its visual automation, tagging and segmentation are built for nurturing an audience — branching sequences that react to behaviour — where Constant Contact’s automation is simpler and aimed at basic welcome series and triggers. Neither is CRM-grade (for lead scoring and pipelines, ActiveCampaign is the specialist), but for shaping a list, Kit wins. Edge: Kit, clearly.

Templates and design

A genuine clash of philosophies. Constant Contact offers more conventional, image-friendly templates; Kit deliberately keeps emails plain and text-like, on the belief that they feel personal and convert better. If you want polished, designed campaigns, lean Constant Contact; if you want emails that read like a note from a friend, Kit’s plainness is a feature. Edge: depends on taste — Constant Contact for design, Kit for the personal-letter feel.

Selling to your list

Kit lets you sell digital products and paid newsletters right beside your subscribers, which is a real advantage for a creator monetising an audience. Constant Contact has basic commerce blocks and its event registration, but selling is more bolted-on. Neither, though, is a full funnel-and-course platform. Edge: Kit for creator commerce — but read the next section.

Growing the audience

Kit has a recommendation network that can actively bring new subscribers to your newsletter — a genuine list-growth mechanism. Constant Contact relies on your own forms and traffic. If growing the list itself matters, this is a meaningful edge. Edge: Kit.

Funnels, courses, checkout

The shared blind spot. Neither gives you real multi-step sales funnels, course hosting with memberships, or full checkout with order bumps and upsells. Kit’s product sales help a creator; Constant Contact has basic commerce blocks; but if selling a system is central, you’ll stitch extra tools around either. Edge: neither — and that’s the opening for an all-in-one.

Where Systeme.io fits

If you read that last point and thought “but I do want to sell a proper offer — a course, a funnel, checkout — not just broadcast,” that’s the real signal. Constant Contact and Kit are both email tools — one support-and-events-first, one creator-and-audience-first — that have added a few selling bits around the edges. Systeme.io comes at it from the other direction: it’s a full business platform where email and automation are just one piece, sitting alongside multi-step sales funnels, a website/landing-page builder, online courses, checkout with order bumps and upsells, and a built-in affiliate program — all in one login, on a genuinely free plan (not a trial).

Here’s the honest trade-off. Systeme.io won’t match Constant Contact’s phone support, event management or small-business pedigree, and it won’t match Kit’s creator-grade tagging, its plain-email craft or its recommendation network for growing a list. Its email tooling is “good enough for most” rather than best-in-class. But if your goal is to build and sell the whole business — capture emails, nurture them, and take the payment for a funnel or course — it does far more for $0 than either dedicated email tool, and you’re not paying a climbing contact-based bill while your list is still small. The thing both Constant Contact and Kit lack — proper funnels and a course platform — Systeme.io includes for free.

So which should you choose?

• Choose Constant Contact if you’re a small business or nonprofit that values support and events — you want a real human (and a phone number) when you’re stuck, and you run event invitations or registrations as part of your business. It’s the dependable, support-first choice.
• Choose Kit (ConvertKit) if your email list is the business — you’re a creator, newsletter writer or course seller who wants visual automation, plain emails that feel personal, the ability to sell digital products straight to your list, and a network that helps grow it. It’s the creator’s audience engine.
• Choose Systeme.io if the real goal is to sell a system, not just send — you want email plus funnels, a course and checkout in one free account, and you’d rather consolidate than stitch tools together. It’s the build-and-sell-it-all choice, started free.

A pattern worth knowing before you commit: these two barely compete, because they’re built for different owners — a local business with events versus a creator with an audience. But notice the thing they share: both bill by contact count, both climb, and neither lets you build a full funnel or course. So before you decide, list the three things you’ll actually do most weeks. If it’s broadcasts, an automation and a signup form, both do that well — and so does a free all-in-one that throws in the selling tools for nothing. Our guide to the best email marketing tool for beginners digs into that choice, and email automation for beginners covers what you actually need automated.

The honest bottom line

Constant Contact and ConvertKit are both genuinely good at the job they’re shaped for — you just have to be honest about which job is yours. Constant Contact wins on support and events and small-business fit; Kit wins on automation, creator commerce and growing an audience. If your business doesn’t clearly sit in one of those camps, notice the thing they have in common: both bill by contact count, both climb, and neither lets you build a full funnel or course. So if you’re building something you intend to monetise as a system — funnels, a course, checkout — the most useful move isn’t choosing between two email tools at all; it’s starting with an all-in-one you can run for free and adding a dedicated email tool later, only if you ever truly outgrow it. Pick the lightest tool that does what you need this month; the platform matters far less than having an audience and an offer worth emailing.
