MailerLite review: is the free plan enough for a small agency?

Getting into MailerLite is straightforward on paper, domain verification, a profile form, then an algorithmic review before you can send. EmailTooltester, which has awarded MailerLite its 'Best Email Marketing Tool for Ease of Use' badge every year from 2023 to 2026, notes the platform requires you to verify your website or explain why you don't have one before your first send. The friction point is the approval stage: Capterra data cited by Omnisend found that 60% of the 88 reviews mentioning account approval were negative, with users reporting delays and unexplained rejections. For an agency onboarding a new client mid-campaign, that queue is a real operational risk. Templates are also locked to paid plans, so free-tier users build from scratch, adding setup time that reviewers on G2 and Capterra consistently flag.

Once approved, the interface earns its reputation. G2 reviewers, 4.6 stars across 1,104 verified reviews, consistently praise the clean UI, drag-and-drop editor, and automation builder as the platform's clearest strengths. An agency-side G2 reviewer noted using MailerLite across multiple brands and agencies for five-plus years, citing the drag-and-drop editor as fast even when managing campaigns for several brands at once. Automation workflows are described across G2, Capterra, and TrustRadius as powerful enough for most B2B and B2C use cases without requiring a tech team. The notable friction points reviewers flag are editor lag on longer emails, no dedicated mobile app, and subscriber-vs-group labeling that isn't always intuitive, minor UX debts that don't break the daily workflow but add up.

For a single small client, MailerLite's feature set is solid: multi-trigger automations, A/B and multivariate testing, segmentation, Shopify and WooCommerce integrations, and an AI writing assistant on Comfort and Power. Where it thins out is in reporting and compliance risk at volume. Analytics cover opens, clicks, bounces, and unsubscribes, but there is no built-in lifetime value tracking, no spam or design pre-send testing, and revenue attribution is basic, gaps that Omnisend, Capterra, and Mailmodo reviewers all flag independently. For a performance marketer who needs to close the loop from Meta or Google spend to email revenue, that means leaning on external analytics. The account suspension policy is the sharper scale risk: MailerLite's published anti-spam policy reserves the right to suspend accounts immediately if bounce rates exceed 5%, spam complaints exceed 0.2%, or open rates fall below 3%, thresholds that any cold or lapsed list can breach, and that reviewers across G2, Capterra, and Trustpilot report hitting without warning.

Support quality is polarised by plan tier. Paid users get live chat that reviewers on Trustpilot and G2 frequently describe as fast and human. Free plan users are directed to MailerLite's community, confirmed by the platform's own help docs, with no live chat access. The polarisation extends to urgent issues: several reviewers on G2 and Capterra report open tickets going unanswered for days, while others on the same platforms call support a genuine retention driver. MailerLite does not offer phone support at any tier, which G2 reviewers consistently flag. The documentation is thorough for standard workflows, but MailerLite describes itself as a self-serve platform and offers no direct migration assistance, a friction point for agencies switching client accounts from other ESPs.

The pricing structure, as listed on MailerLite's pricing page as of July 2026, is Free (250 subscribers, 2,500 emails/month), Comfort (from $12/month), and Power (from $25/month), with a 10% annual discount and 30% off for nonprofits. That entry price is significantly below comparable tiers at Mailchimp or ActiveCampaign, and TrustRadius reviewers consistently cite the ROI as outstanding relative to feature depth. The sting is the free plan: MailerLite cut the subscriber ceiling from 1,000 to 500 in September 2025, then again to 250 on June 16, 2026, a 75% reduction in 12 months. Agencies running even modest client lists will hit that ceiling fast and face a paid upgrade. At $12, $25/month for a small list, the Comfort and Power plans still represent strong value, but the refund policy is unforgiving: MailerLite's terms confirm it reserves the right to terminate accounts for policy violations without refund, a real cost exposure on annual plans.
