Mailjet features: what you get on each plan
Mailjet covers 26 of the 28 features we test, and the gating is unusually top-heavy. The free plan gives away the editor, the API, the SMTP relay, webhooks and the form builder. Everything a marketing team eventually wants — automation, A/B testing, landing pages, extra seats — waits until Premium at $27 a month.
Two products share one account here. The developer half is complete from the free plan: transactional API, SMTP relay, the Event API with six webhook types, and a templating language with conditions, loops and formatting functions. The marketing half is staged, and the staging is lopsided: Starter and Essential buy reach, not campaign tooling.
The free plan is capped at 200 emails per day against a 6,000 monthly allowance, so it is a test bench rather than a small production sender.

Where the gate falls
Three of the four rows marked Premium are the features a team migrating from a cheaper tool goes looking for first. Automation needs the 15k Premium plan or higher, A/B testing is Premium-only in the editor’s own wording, and landing pages never appear below it. Essential buys reach — unlimited contacts and segmentation — but nothing to act on that reach with.
