| Composes with | the largest monthly figure in the free sender set at 6,000, cut down to 200/day. It composes with the same domain as Brevo and Resend, which is where the reputation problem starts. |
|---|
| Reliability | over-quota mail is reported to be queued for three days and then discarded, which makes an overrun silent data loss. That sentence is reported and not documented: the knowledge-base article it came from, documentation.mailjet.com article 360043048393, returns 404 on 2026-10-22, and the pricing page does not state it |
|---|
| Notes | The 30:1 monthly-to-daily ratio is the same shape as Resend's. The queue-and-discard behaviour is the technical fact a reader needs before pointing a campaign at it. |
