Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
MailerLite
- Free plan caps at 250 subscribers, 2,500 monthly emails and 2 user seats
- Comfort plan is limited to 3 user seats; unlimited seats require the Power plan
- Pricing scales with subscriber count and email volume rather than a flat seat rate, and resets to the plan's subscriber ceiling each billing anniversary
- Annual billing earns only a 10% discount versus monthly, smaller than many competitors' annual discounts
OneSignal
- Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
- Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier
