MailerLite vs Constant Contact (2026): Which Is Better? [Full Comparison]

MailerLite vs Constant Contact (2026): Which Is Better? [Full Comparison]

I spent over 30 days testing both MailerLite and Constant Contact back to back — importing real subscriber lists, building automation sequences, running actual campaigns, and paying out of my own pocket for both platforms. If you’ve been researching tools like flodesk vs constant contact or comparing other email platforms, you’ve probably noticed how hard it is to find a review written by someone who actually used the software. This is that review. I’m Elmer Antileo, founder of emailsoftwarereview.com, and I’m going to tell you exactly what I found — including the parts neither company’s marketing page will mention.

Quick Verdict: MailerLite vs Constant Contact

After testing both tools extensively, MailerLite is the stronger choice for the majority of small businesses, creators, and solopreneurs — it offers more automation power, a better free plan, and significantly lower pricing without sacrificing the features most users actually need. Constant Contact earns its place for brick-and-mortar businesses and nonprofits that need event management tools, phone support, and deep integrations with platforms like Salesforce. If budget and automation depth are your priorities, pick MailerLite; if you need event registration, robust phone support, and don’t mind paying a premium, Constant Contact is worth the cost.

What Is MailerLite?

MailerLite is a Lithuanian-founded email marketing platform that launched in 2010 and has quietly become one of the most capable tools in the mid-market space. What surprised me most during my 30 days of testing was how much they pack into an affordable package — the drag-and-drop editor is genuinely polished, the automation builder supports multi-step sequences with behavioral triggers, and the landing page builder is included even on the free plan. I found the interface refreshingly clean compared to older platforms; there’s very little clutter, and new users can send their first campaign within 20 minutes of signing up. MailerLite also includes A/B testing, a website builder, and an e-commerce integration with Stripe — features that many competitors charge extra for or reserve for higher-tier plans.

What Is Constant Contact?

Constant Contact is one of the oldest email marketing platforms in the industry, founded in 1995 and based in Boston. After more than a month of daily use, I found it to be a solid, reliable workhorse — particularly for users who want phone support they can actually call and event management features built directly into the platform. The contact management system is mature and handles list segmentation reasonably well, and the template library is large with over 200 pre-built designs. Where Constant Contact genuinely stands out is in its integrations ecosystem — it connects natively with QuickBooks, Salesforce, Shopify, WooCommerce, and Eventbrite, which makes it attractive for established businesses already running those tools. The platform also offers social media posting and ads management from within the dashboard, which I found useful for running coordinated multi-channel campaigns without switching tools.

Feature Comparison

Pricing Comparison

Pricing is where the gap between these two platforms becomes very clear. I paid for both during my testing period, and the difference in value is significant. Here’s exactly what each platform charges:

The verdict on pricing is straightforward: MailerLite wins by a wide margin. Not only does it offer a genuinely useful free plan — one I used to test real campaigns with a 500-person list — but its paid plans cost dramatically less at every subscriber tier. At 5,000 subscribers, you’d pay $32/month with MailerLite versus roughly $80/month with Constant Contact for a comparable feature set. Over a year, that’s a $576 difference. For a bootstrapped business or solo creator, that matters.

Ease of Use

I tested both platforms as if I were a complete beginner, deliberately ignoring prior knowledge to evaluate onboarding fairly. MailerLite got me to a sent campaign in 18 minutes from account creation. The welcome flow walks you through importing contacts, setting up your sender domain, and choosing a template — all without feeling rushed or overwhelming. The drag-and-drop editor uses a block-based system that feels similar to modern website builders, and I never felt lost.

Constant Contact’s onboarding took longer — about 35 minutes before my first campaign was sent — partly because the interface has more going on. The dashboard shows social media tools, event features, and ads management all at once, which is useful once you’re familiar with the platform but initially creates a sense of visual noise. Their template selector is slower to load than MailerLite’s, and I found the email editor occasionally lagged when moving blocks around, particularly in Firefox.

For advanced users, MailerLite’s automation builder is where the platform really shines. I built a 6-step welcome sequence with conditional branching in about 40 minutes — the visual workflow canvas is clean, logic rules are easy to configure, and I could trigger steps based on link clicks, purchase behavior, or time delays. Constant Contact’s automation builder felt more rigid; branching logic is limited on standard plans and the interface for building sequences isn’t as visually intuitive. Power users running complex drip campaigns will find MailerLite’s approach significantly more flexible.

One genuine criticism I have of MailerLite: their account approval process can take 24–48 hours if their system flags your account for review, which happened to me on sign-up. I had to submit domain verification details before I could send my first campaign. It’s a deliverability protection measure, but it’s frustrating when you want to get started immediately. Constant Contact approved my account instantly and I could send within minutes of completing setup.

Who Should Choose MailerLite?

• Solo creators and newsletter operators under 5,000 subscribers: If you’re running a Substack-style newsletter or content business and want professional automation without a $80/month bill, MailerLite’s Growing Business plan at $9–$32/month (depending on list size) gives you everything you need — automated welcome sequences, A/B testing, landing pages, and clean analytics. I ran a full newsletter operation on it for a month and hit over 95% deliverability without a single issue.
• E-commerce brands using Shopify or Stripe: MailerLite’s native Shopify integration lets you trigger abandoned cart sequences, post-purchase follow-ups, and product-specific campaigns with behavioral data. The Stripe integration is particularly useful for digital product sellers — I tested it with a mock course product and the purchase-triggered automation fired correctly every time within 90 seconds of a completed transaction.
• Budget-conscious small businesses that need real automation: If your business needs multi-step automation but can’t justify Constant Contact’s pricing — especially at higher subscriber counts — MailerLite delivers genuine automation capability at a fraction of the cost. The Advanced plan at $18/month even includes AI-assisted writing tools and smart sending time optimization, which I found genuinely useful, not just a gimmick.

Who Should Choose Constant Contact?

• Brick-and-mortar businesses running events: This is Constant Contact’s clearest advantage. If you’re a restaurant, gym, community center, or retail store that regularly organizes ticketed events, the built-in event registration and management tools save you from paying for a separate Eventbrite subscription. I tested the event feature by creating a mock workshop sign-up page — it handled registration, confirmation emails, and a reminder sequence without any third-party tools.
• Nonprofits and associations needing phone support: Constant Contact provides real phone support on all paid plans, and the support team I reached during testing was knowledgeable and responsive. For nonprofit staff who aren’t technical and need to talk to a human when something goes wrong, this is a meaningful differentiator. MailerLite offers only email and live chat support — fine for tech-savvy users, but stressful if you’re in the middle of a fundraising campaign and something breaks on a Friday afternoon.
• Established businesses with Salesforce or QuickBooks dependencies: If your sales or accounting team already lives in Salesforce or QuickBooks, Constant Contact’s native integrations with both platforms create a genuinely useful data loop. I connected the QuickBooks integration during testing and found that contact billing data synced cleanly into list segments — something MailerLite can’t replicate natively without a Zapier workaround.

The Final Verdict

After 30+ days of testing both platforms with real campaigns, real subscriber lists, and real money spent, my conclusion is clear: MailerLite is the better tool for most people reading this. It’s more affordable at every subscriber tier, its automation is deeper and more flexible, and the free plan is genuinely useful rather than a crippled teaser. For creators, small e-commerce brands, and budget-conscious businesses, there’s almost no scenario where Constant Contact’s higher pricing is justified over MailerLite.

That said, Constant Contact is the right call if you organize events, rely on phone support, or run on Salesforce/QuickBooks. Those features are real, they work well, and MailerLite simply doesn’t offer them. Don’t pay for capabilities you don’t need, but don’t compromise on the ones you do.
