ActiveCampaign vs MailerLite

This comparison comes down to how much automation complexity you actually need. ActiveCampaign has the deepest automation builder in email marketing — 135+ triggers, 750+ recipes, built-in CRM, lead scoring, and site tracking. MailerLite has solid automation for basic workflows but nothing close to ActiveCampaign's depth. The trade-off is cost: MailerLite costs $10/month at entry level with a free plan. ActiveCampaign starts at $19/month with no free plan, and documented price hikes of 20-100% have hit existing customers. At 2,500 subscribers, MailerLite is around $25/month; ActiveCampaign is around $49/month. If you use less than 10 automation workflows, MailerLite saves you money without meaningful sacrifice. If automation is your competitive advantage, ActiveCampaign earns its premium.

Our pick: MailerLite (7.5/10 vs 7.4/10)

MailerLite wins 4 out of 6 categories. ActiveCampaign is better for: mid-sized businesses (1k-25k contacts) that actively use complex automation daily.

Pros & Cons

ActiveCampaign

First-rate automation builder with 135+ triggers and 750+ pre-built recipes — no other platform matches this depth (G2: 4.5/5 from 14,000+ reviews)

900+ integrations including 40+ new ones added in 2025 alone (Wix, Webflow, SOCi) — plays nicely with almost anything

Deep segmentation with new AI Segments Agent that lets you describe audiences in natural language

Aggressive price hikes documented at 20-100% for existing customers. Real examples: $588/yr to $1,800/yr; $1,400/mo to $2,800/mo; $2,000/yr to $7,800/yr

As of November 2025, now charges for ALL contacts including unsubscribed, bounced, and unconfirmed — same controversial practice as Mailchimp

Trustpilot rating of 2.8/5 from 1,358 reviews — billing complaints, cancellation horror stories, and users charged after cancelling

MailerLite

89.8% deliverability rate across 5 independent test rounds (EmailToolTester) — highest we found among all platforms tested

76% cheaper than Mailchimp at 2,500 subscribers ($25/mo vs ~$69/mo for equivalent features)

Won 'Best Email Marketing Tool for Ease of Use' every year from 2023-2026 across G2 and Capterra

Account approval/termination is a real problem — 60% of Capterra reviews mentioning it were negative. Users report accounts terminated without warning and no refund

Free plan was cut from 1,000 to 500 subscribers in September 2025, with no templates on free (must design from scratch)

Limited analytics — no heatmaps, no custom reports, no revenue attribution, no bot-click filtering. If data matters to you, this will frustrate you
