How We Chose These Platforms
We compared final monthly costs at 1,000, 10,000, 50,000, and 100,000 subscriber tiers. We prioritized platforms that keep unlimited sends, automation, and landing pages on lower-tier plans, and we tested free-plan feature limits and upgrade paths.
The cheapest option is not always the best value — we weighted feature depth, deliverability, and support quality against price.
