listmonkA superb broadcast tool, but no built-in welcome sequence means it misses the stated job.

People still pay for MailerLite because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface. If none of that applies to you, any pick above saves $144 a year.
Is there a free alternative to MailerLite?
Yes: Brevo Free, EmailOctopus Free, Kit Free and 2 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own MailerLite?
Our verdict is PARCIAL. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For MailerLite, send newsletters, build forms, and run a small welcome sequence. The hard boundary is deliverability, editor polish, landing pages, automations, and integrations, plus deliverability, growth network, and integrations. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/mailerlite.
