Choosing between AWeber and Constant Contact is unusual, because most email-tool comparisons pit a modern newcomer against a dated veteran — and here you’ve got two veterans. Both have been around for the better part of two decades or more, both are dependable, both prize human support, and both will answer the phone when you’re stuck. They’re more alike than almost any other pair in this market. So the choice isn’t reliability versus polish; it’s a handful of specific differences that quietly decide it.

Put simply: AWeber is the autoresponder pioneer — lean, dependable, with a genuinely free plan and a lower bill. Constant Contact is the small-business and events veteran — built around local businesses and nonprofits, with built-in event invitations few rivals offer, but no permanent free plan and a higher price. Neither is wrong; they’re tuned for slightly different owners.

Neither AWeber nor Constant Contact 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, nonprofit discounts 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 own site before you decide.

The core difference in one sentence

AWeber is the dependable, support-first autoresponder pioneer — a plainer, slightly dated interface, simple and reliable autoresponders, a long deliverability track record, a genuinely free tier and a generally lower bill, with phone support for everyone. Constant Contact is the support-first small-business and events veteran — built around small businesses, nonprofits and local organisations, with the same phone-a-human reassurance plus built-in event invitations and registration, but only a free trial and a price that tends to run higher.

The fastest way to feel the difference: finish this sentence — “Beyond sending email, the thing I most need is ___.” If the blank is to start free and keep the bill low, you’re probably an AWeber person. If it’s to run events and registrations from the same tool, you’re probably a Constant Contact person. If it’s neither — if you just need broadcasts and an autoresponder — both do that equally well, and the free plan likely tips it to AWeber.

AWeber: the dependable autoresponder pioneer

AWeber has been around since the late 1990s and more or less popularised the email autoresponder. Its calling card today isn’t a flashy feature — it’s reliability, support and a genuinely free way in.

Pros:

• A real free tier. Unlike Constant Contact, AWeber has a permanent free plan, not just a trial — so you can start, learn and grow a small list without a bill or a ticking clock. For a lean beginner this is the single biggest practical difference between the two.
• Human support, including phone. Responsive support — email, chat and actual phone calls — is available to customers, which is genuinely valuable if you want to talk to someone. (This is one thing both veterans share.)
• Simple, reliable autoresponders. Setting up a welcome sequence or a tag-based campaign is straightforward, and AWeber’s long deliverability track record means those emails tend to land. Pricing tends to run lower than Constant Contact’s for comparable list sizes.

Cons:

• The interface feels dated next to newer tools — functional rather than glossy, and it shows its age in places. (Constant Contact’s does too, so this isn’t a deciding factor between these two.)
• Automation is fairly basic. AWeber’s Campaigns feature handles autoresponders and tag-based sequences fine, but if you want deep conditional branching and behaviour-based flows, you’ll hit its ceiling. (For real depth, ActiveCampaign is the tool.)
• Contact-based pricing climbs as your list grows, like almost every tool here.
• No event management and email-first, so no native webinars, no real sales funnels and no course hosting — you’ll bolt extra tools on to sell.

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:

• Built-in event management. Event invitations and registration are one of its more distinctive features; most email tools — AWeber included — don’t include them natively. If you run live events, this alone can justify it.
• Human support, including phone. Like AWeber, Constant Contact offers responsive phone, chat and email support — the same reassurance for a beginner or a busy small-business owner who’d rather talk to a person.
• Small-business and nonprofit tooling. It’s built around local businesses, nonprofits and organisations, with baked-in tooling for that audience and nonprofit discounts, plus a long, dependable deliverability track record.

Cons:

• Only a free trial, not a permanent free plan, so there’s no genuinely free tier to grow on — the clearest contrast with AWeber.
• Contact-based pricing climbs as your list grows, and many people find it expensive for what is, at heart, fairly basic email — it tends to run higher than AWeber.
• The interface and automation feel dated next to a modern tool, and the automation is light, so you’ll hit its ceiling sooner if you want real branching logic — the same limitation AWeber has.
• Email-first beyond the events piece, so no real sales funnels or course hosting — you’ll bolt extra tools on to sell.

Head to head on what actually matters

Free plan and pricing

This is the clearest split. AWeber has a permanent free plan; Constant Contact has only a free trial — so at the smallest sizes AWeber can be genuinely free where Constant Contact can’t. Both then bill by contact count and both climb, but AWeber tends to run lower for comparable list sizes, and Constant Contact is the one people more often call expensive for basic email. The counterweight: Constant Contact offers nonprofit discounts, which can change the maths if you qualify. Price both against your actual contact count on their own pages. Edge: AWeber, clearly — especially to start.

Support

Near-even, and that’s rare. Both offer responsive human support including phone, which is the thing that sets this pair apart from most modern rivals. If “I want to be able to call someone” is on your list, you’re covered either way — so this won’t decide it. Edge: even.

Events

No contest. Constant Contact has built-in event invitations and registration — a genuinely distinctive feature. AWeber has nothing comparable natively. If live events or registrations are part of your business, this is close to a deal-maker. Edge: Constant Contact, clearly.

Automation

Close, and neither is a power tool. AWeber’s Campaigns and Constant Contact’s automation both handle autoresponders, welcome series and tag-based or trigger-based sequences at a basic level, and both keep it deliberately simple. You’ll outgrow either if you want conditional branching, lead scoring or a CRM — and then ActiveCampaign is the answer, not the other one of these two. Edge: even — lean AWeber only slightly for tag-based campaigns.

Autoresponders and email heritage

AWeber has the stronger claim here — it popularised the autoresponder and stayed email-first for its whole life, which shows in how naturally sequences and tagging fit together. Constant Contact’s email is dependable but its heart is small-business marketing and events rather than the autoresponder craft. Both have solid, decades-long deliverability reputations. Edge: lean AWeber on email heritage; call deliverability even.

Small-business and nonprofit fit

Constant Contact is purpose-built for local businesses, nonprofits and organisations, with tooling and discounts aimed squarely at them. If you’re a nonprofit or a bricks-and-mortar local business — especially one running events — it fits like a glove. AWeber serves the same crowd capably but without the same tailored tooling. Edge: Constant Contact for that specific audience.

Funnels and selling

This is where they’re the same, not different. Neither is a full course-and-membership platform with proper checkout upsells and multi-step sales funnels. Both have landing pages and basic email-first selling around the edges (Constant Contact adds events), but if your goal is to sell a system, both leave you bolting on extra tools — which is exactly the gap the next section is about. Edge: neither — read “Where Systeme.io fits.”

Where Systeme.io fits

If you read the funnels and selling section and thought “but I do want to sell a proper offer — a course, a funnel, checkout — not just broadcast,” that’s the real signal. AWeber and Constant Contact are both email tools with a few selling bits around the edges; neither is built to take the payment for a system. Systeme.io comes at it from a different 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 the decades-long, email-first deliverability pedigree of either veteran, it has no phone support like both of theirs, and it has no event management like Constant Contact’s. Its email tooling is “good enough for most” rather than best-in-class, and its templates are more functional than glossy. 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 of these tools, and you’re not paying a climbing contact-based bill while your list is still small. The thing both AWeber and Constant Contact lack entirely — funnels and courses — Systeme.io includes for free.

So which should you choose?

• Choose AWeber if you want to start free and keep the bill low — a permanent free plan, dependable autoresponders and the same phone-a-human support, at a generally lower price. It’s the leaner, cheaper of the two veterans, and the safer default if you don’t specifically need events.
• Choose Constant Contact if you run events or you’re a small business or nonprofit that values its tailored tooling — built-in event invitations and registration, nonprofit discounts and the same human support, worth its higher bill if those features earn their keep. It’s the small-business-and-events choice.
• 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 pay for an email tool and stitch the selling on later. It’s the build-and-sell-it-all choice, started free.

A pattern worth knowing before you commit: people picking between AWeber and Constant Contact are usually choosing between cost and events — the cheaper free-plan veteran versus the one that runs your registrations. Both are genuinely good at the email job, and both give you a phone number, which is rare. But notice the thing they share — both bill by contact count, both climb, and neither lets you actually sell beyond basic email (and events). So before you decide, list the three things you’ll actually do most weeks. If it’s broadcasts, an autoresponder and a signup form, both do that well — and so does a free all-in-one that throws in the funnels and course 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

AWeber and Constant Contact are both genuinely good, genuinely dependable email veterans — you won’t make a bad choice picking either, and both give you the phone support that newer tools drop. AWeber wins on the free plan and the lower bill; Constant Contact wins on events and small-business and nonprofit fit. If those factors don’t decide it for you, notice the thing they have in common: both bill by contact count, both climb, and neither is a sell-the-whole-business platform — there are no real funnels or courses in either. 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.
