| Free tier | 500 emails/month on the free plan, 1 domain, 100 daily API requests unit requests; metered on request-count |
|---|---|
| Price | none stated |
| Per-object cap | not applicable |
| Retention | 1-day activity data retention on the free plan |
| Egress | not applicable: an outbound sender |
| Identity | card a card is required even for the free plan: the pricing FAQ answers 'Why do you need my credit card details for the Free plan?' with 'we just ask that you provide this information to prevent abuse of the platform', which is to say to limit excess use |
| Limits | counts of things, not rates, so no vocabulary kind names them: 1 sending domain. the 100 figure on the page is daily API requests and not daily emails, so one request may address many recipients |
| Binding | request-rate |
| Interface | rest the MailerSend email API and SMTP relay |
| Tooling | curl, any SMTP client |
| Composes with | composes with a domain and with nothing that needs volume. |
| Reliability | the pricing page leads with a 14-day Professional trial, which is a different offer |
| Notes | The census named this provider and opened no page for it; the free tier is 500/month, a fifth of Resend's and a sixtieth of Brevo's. The trial banner is the trap: the page advertises '14 days free to integrate' above a free plan that is permanent and much smaller. |
