Mailjet

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).

Deliverability: not yet tested. Mailjet is in the queue for our seed-list test cycle; the protocol is documented in how we test, and measured results publish to the email deliverability ranking.

What others say about deliverability

Warrior Forum — 'Have you used Mailjet, is it good?'Forumunknown
Mixed practitioner thread (~2017-2018): one marketer calls Mailjet 'total garbage' citing 'tons of reports of people paying and getting banned for no reason' and opaque email blocking, while another participant reports the service delivers fine for them.
EmailDeliverabilityReport — Mailjet reviewExpert study1 July 2026
In this site's own test (10,968 emails, 2026/7 round), Mailjet scored 79.62% inbox placement with 18.97% in spam and 1.40% lost, ranking 6th of 23 providers (92/100), ahead of Mailchimp (77.75%) and SendGrid (75.36%).
Warmy blog — Mailjet deliverability: best practices and issuesArticle1 July 2026
Warmup-vendor article (promotes its own tool) whose main Mailjet-specific finding is that Mailjet's default Return-Path (bnc3.mailjet.com) prevents SPF alignment with the visible From domain, and that abrupt account suspensions recur in user complaints; attributes most spam placement to sender-side factors.
Mailflow Authority — Mailjet reviewReview site1 March 2026
Practitioner reviewer reports inbox placement on Mailjet's lower-tier shared-IP plans is 'inconsistent,' with clients hitting Gmail's Promotions tab more than on Postmark or dedicated-IP SendGrid, and recommends dedicated IPs for critical transactional mail.
