Once segments are made, users can send targeted emails, create automation, and personalize the content specifically for that audience. Up to 1,000 segments can be made to slice lists for very customized communication. Overall, the segmentation provides the essentials although more technically adept users may want additional options.


ActiveCampaign offers robust segmentation capabilities with over 90 categories for dividing subscriber lists including email engagement, forms submitted, order history, custom field values, and more. An intelligent segment builder makes it easy to create very customized segments with specific parameters.

Once created, segments can be targeted with tailored messaging across email, site popups, SMS, and other channels. The level of personalization takes things to an advanced level great for converting leads. Power users will appreciate the depth of options.

For those needing more than email marketing, ActiveCampaign delivers on multiple fronts.

3. Ease of Use


MailerLite uses an intuitive drag-and-drop editor that makes creating emails, landing pages, forms, and automations simple even for those without technical skills. The clean interface allows new users to quickly find desired functions thanks to thoughtful menu layouts and prompts guiding initial configuration.

Within minutes you can set up subscriber lists, design professional templates from pre-made options, schedule your first campaign, and track performance with the digestible analytic dashboards. While those wanting maximum customization may find options limited, MailerLite minimizes complexity.


In contrast, ActiveCampaign provides a much steeper learning curve due to the expansive suite packed with hundreds of features spanning email, automation, messaging, CRM, and beyond. While extremely powerful, novices may initially feel overwhelmed navigating the less-intuitive interface.

Expect a time investment upfront in mastering core functions like list building, template editing, and creating basic sequences. And tackling advanced tools like journey building requires significant ramp-up education. But for those willing to climb hurdles, immense marketing power awaits.

Winner: MailerLite

With its clean dashboard guiding users into essential functions using an easy drag-and-drop approach requiring no technical expertise, MailerLite wins for overall ease of use and faster mastery, especially for email marketing beginners. ActiveCampaign undisputedly delivers vastly greater depth but demands much more upfront learning and time commitment.

4. Email Deliverability


MailerLite focuses heavily on maximizing email deliverability through advanced verification and sender reputation monitoring. All outgoing emails are authenticated using SPF, DKIM, and DMARC to ensure high inbox placement rates across all major ISPs.

The platform offers deliverability tips during campaign creation and lets users preview inbox rendering. Granular browsing, device, and email client analytics allow ongoing optimization. Overall open and click rates typically reach industry standards.


Similarly, ActiveCampaign utilizes email authentication protocols like SPF, DKIM, and DMARC for strong deliverability. A dedicated deliverability team works continuously behind the scenes, monitoring ISP feedback and managing the sender’s reputation.

The platform also provides inbox placement tests for further optimization and offers deliverability consulting services. Open and click rates meet or exceed benchmarks. Additional IP addresses can be purchased for more aggressive email-sending strategies.

Winner: Tie

Both MailerLite and ActiveCampaign focus heavily on maximizing email deliverability through sender reputation monitoring, inbox placement previews/testing, and email authentication protocols. Their core deliverability capabilities result in industry-standard open and click rates. For most use cases, users can feel confident in strong inbox placement and engagement.

5. Customer Support and Community


MailerLite provides email-based customer support with fairly quick response times during business hours. They also offer an online knowledge base with articles, guides, and videos to address common questions around email creation, list management, troubleshooting issues, and more.

For community support, users rely heavily on the active MailerLite Facebook group with over 25,000 members. The forum allows customers to get advice and best practices from peers handling similar email campaigns and challenges.


ActiveCampaign provides 24/7 live chat, email, and phone support so customers can get immediate answers any time day or night. Response times are prompt and the customer service team is very knowledgeable. They also maintain an extensive help desk documentation hub with tutorials, videos, webinars, and more.

In terms of community, the ActiveCampaign Facebook group has close to 50,000 users networking, collaborating sharing ideas, and assisting each other in managing campaigns across email, automation, CRM, and other product features.

Winner: ActiveCampaign

With round-the-clock instant access to support reps plus a robust self-help content hub, ActiveCampaign edges out MailerLite for an overall customer support experience. While both platforms have wonderful community forums, the heightened activity within the ActiveCampaign group highlights its role as the strongest ecosystem.

6. Integrations


MailerLite connects with over 700+ third-party applications via Zapier for building automated workflows between the email platform and tools like WordPress, Google Analytics, Stripe, Facebook, and more. Users can also embed forms or integrate e-commerce data from outlets like Shopify.

However, the integrations focus exclusively on function and do not offer the deep level of data syncing available in other solutions. However, common needs like list growth, campaign analysis, and order notifications can be achieved without advanced coding skills.


ActiveCampaign truly stands out with its 500+ native integrations with leading applications in CRM, e-commerce, payments, webinar software, chat platforms, and popular SMB tools. Real-time data syncing allows users to capture subscriber interactions across channels for complete journey mapping.

Zapier is also available to connect additional apps, further expanding options for comprehensive tracking, segmentation, and engagement both online and off. Those wanting holistic visibility into subscriber lifecycles will find tremendous value.

Winner: ActiveCampaign

While MailerLite covers basic function connections, ActiveCampaign’s unparalleled depth of natively integrated platforms provides complete subscriber insights and harmonized experiences across sales, email, messaging, ads, and more. The breadth and real-time data sync power targeted segmentation and behavior-based automation vital for conversions.

7. Pricing


One of MailerLite’s biggest advantages is its free forever plan that allows up to 1,000 subscribers and 12,000 emails per month. This covers the needs of most solopreneurs and early-stage startups. Features included in the free plan are full access to email creation tools, a drag-and-drop editor, ready-made templates, automation with triggers, basic analytics, pop-up forms, and integrations.

The only major restriction is the lack of grouping options and access to one-on-one customer support. But for fledgling businesses wanting professional email capabilities without hurting cash flow, it’s an incredible offer.

Paid tiers scale up to 25,000 subscribers priced very competitively from $10 – $50 monthly when billed annually. Again, core features around analytics, automation, etc remain consistent making the free and paid plans equally robust.


ActiveCampaign takes a much more traditional approach requiring payment upfront for access to most features. The Lite plan at $29 monthly allows just 500 subscribers with email and forms. But you need the Plus tier ($49) to unlock automation, and Professional ($149+) for grouping/segmentation.

This means small businesses have to immediately invest real budget if they want beyond basic email blasts. However, custom enterprise pricing is available for massive subscriber lists above 100,000 where costs per subscriber drop dramatically making it more affordable at large scale. But again, smaller users pay a premium comparatively.

Winner: MailerLite

Given its rare free forever plan with full professional email marketing capabilities and a few premium features, MailerLite beats ActiveCampaign when it comes to catering to small businesses, startups, and solopreneurs working with very limited budgets. The ability to access premium tools for free makes it a no-brainer for early-stage needs.

8. Reviews and Reputation


MailerLite earns positive reviews from users, experts, and industry analysts thanks to its simple email editor, quality templates, automation features, and generous free plan. Users highlight the intuitive interface making onboarding easy for beginners not needing advanced functionality.

Some negatives cited are occasional deliverability hiccups, lack of advanced analytics, and more limited grouping options. But most agree that MailerLite excels for anyone wanting an affordable starter email marketing platform.


ActiveCampaign garners excellent reviews as a leader in email marketing automation with consistent praise for the wide array of built-in CRM, sales, and marketing tools driving complete customer journeys from first contact across channels to closed deals. Users highlight robust segmentation capabilities and insightful analytics revealing campaign ROI.

Drawbacks mentioned include the steeper learning curve, higher pricing, and an occasionally overwhelmed interface. But for growing businesses wanting extensive functionality beyond basic email, most deem ActiveCampaign as the premier one-stop powerhouse.

Winner: Tie

Both platforms earn outstanding feedback for aligning with the needs of their respective target users. MailerLite caters better to beginners wanting simplicity, while ActiveCampaign wins on advanced functionality for sophisticated marketing automation. Ultimately both achieve their core goals for successful marketing campaigns very well resulting in a tie.
