The cheapest credible paid plan with automation, a website and landing pages included, and unsubscribed contacts are not billed.
Systeme.io
All-in-one for $17/mo: email, funnels, courses and a website in one subscription, with a free plan up to 2,000 contacts.
Brevo
Pay per email volume, not contacts. Ideal for large lists with infrequent sends.
GetResponse
Strong feature-to-price ratio with unlimited sends, landing pages and AI tools; webinars need the Creator plan.
Flodesk
Design-led templates with unlimited sends. Flat-rate pricing ended for new members in December 2025, so the price now rises with your list.
AWeber
Affordable and simple. Great for solopreneurs who want reliable email without complexity.
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 compared free-plan feature limits and upgrade paths using official pricing and documentation.
The cheapest option is not always the best value — we weighted feature depth, deliverability, and support quality against price.
Also worth a look if automation matters more than a free plan: Moosend costs $9 a month at 500 contacts and $88 at 10,000, with unlimited sends and multi-step automation (prices checked October 8, 2026).
