How We Chose These Platforms
We compared free-plan limits on subscribers, monthly sends, and feature access. We only included platforms where the free plan is genuinely usable for building a list, not a stripped-down teaser.
We also tested upgrade paths, since a free plan should help you grow into paid features without forcing a migration.
