Mailjet: User reviews, pricing & features
Mailjet covers email marketing alongside a transactional API and SMTP sending. The company is owned by Sinch, with the brand unchanged — mailjet.com served its own homepage directly when we verified it in August 2026. Most of the search demand we measured for Mailjet comes from Europe, and our protocol runs it through both the marketing and transactional test lines.
A free plan includes 6,000 emails per month with a 200-per-day cap. Paid plans start at $9/month (Starter, 8,000 emails — below our 10,000-email normalization target); the cheapest covering tier is Essential at $17/month on the 15,000-email step. The tier covering automation, API access, and branding removal is Premium at $27/month — the automation gate was re-checked 20 August 2026. Pricing checked 19 August 2026. The curve steepens sharply with volume: Premium costs $27/month at the 15,000-email step (our 1,000-contact equivalent) but $470/month at the 500,000-email step (the 50,000-contact equivalent), with Essential capped at 50,000 emails (multi-volume capture, 21 August 2026).

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on Mailjet's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
