Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Mailjet
- Free plan caps at 6,000 emails per month with a hard 200 emails per day limit
- Starter plan is capped at 2,000 contacts; unlimited contacts require the Essential tier
- Email credits do not roll over and unused emails expire at the end of each billing cycle
- Essential and Premium plans both cap at 15,000 emails per month for $17 and $27 respectively, so the price increase buys other features, not more volume
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
