Best offer on record: Free plan (permanent free tier, Email). 4 verified findings, checked 2026-10-22.
Offers
Free plan (permanent free tier, Email) high confidence
$0/month forever: 6,000 emails/month with a hard cap of 200 emails/day, 1,000 contacts (primary + subaccount combined, exclusion list included). Includes Send API, SMTP Relay, Webhooks (event API), MJML, drag-and-drop Advanced Email Editor, email templates, GDPR subscription forms, basic statistics, form builder, email tracking consent, up to 1 subaccount. Ongoing overages beyond the monthly allowance are billed in 1,000-email blocks; unused credits expire each billing cycle.
Eligibility
Anyone, no age/funding limits; no credit card required at sign-up (official FAQ: 'No, there is no credit card required for the free plan at sign up'). No .edu email requirement. Free ticket support only in the first month.
How to claim
Sign up at mailjet.com (signup page -> pick Free plan). No CC. Then add/validate a sender address or domain and set up SPF/DKIM to send.
Expiry
Indefinite — no sunset date on the Free plan. Inactivity policy: re-engagement emails at 2/6/9/12 months of inactivity, 30-day deletion notice at 12 months, permanent deletion at ~400 days of inactivity (all data gone).
Gotchas
200/day cap: excess emails queue up to 3 days then are PERMANENTLY dropped — unusable for time-sensitive sends >200/day. Campaigns can target max 200 recipients at once. Exceeding 1,000 contacts (anywhere in the account, incl. exclusion list) triggers an automatic send hold on both primary and subaccount until trimmed or upgraded. Since Oct 6, 2025 the contact cap dropped to 1,000 and template download (HTML/MJML) is no longer available on Free. No A/B testing, automations, segmentation, landing pages, dedicated IP. Mailjet logo stays in footer.
30-day Free Premium trial (auto on new signups) medium confidence
Every new account gets Premium features free for the first 30 days: Brand Kit, AI Templates (1 free test), advanced image editor, saved & linked/prebuilt sections, dynamic content, collaboration tools, labels, version history, landing pages (create only, not publish), segmentation, A/B testing, advanced analytics, email automation, bot-activity detection, preference center. NOT in trial: AI Assistant, email validation, custom landing-page domains, inbox email previews, template downloads, account sharing.
Eligibility
All new Mailjet signups (students, startups, anyone). No credit card required — after the 30 days you are automatically moved to the Free plan, not billed.
How to claim
Just sign up at mailjet.com; trial is automatic. Upgrade in-account before day 30 to keep Premium features.
Expiry
30 days from account creation, then auto-downgrade to Free plan (features lock). Existing plan limits still apply during trial: Free-plan accounts keep the 200 emails/day cap during the trial.
Gotchas
Trial-vs-free: during the trial your sending limits are still those of your plan (200/day on Free), so the trial unlocks features, not volume. Several Premium-only features are unavailable even in trial. The trial is marketing-positioned as 'free premium trial' but the account default is the Free plan — no charge on expiry.
Startup program (Premium free-window) — UNVERIFIED third-party claim low confidence
Third-party deal aggregator claimstartupgrants.com describes an application-based Mailjet startup program giving qualifying early-stage companies 'an extended stretch of its paid Premium tier at no cost' (headline ~$300 value), with case-by-case approval. No corresponding page exists on mailjet.com or in the Mailjet Help Center (searches for 'startup program' surface only generic startup-marketing landing pages). A similar unverifiable 15%-off-startup/nonprofit code circulates on coupon sites.
Eligibility
As claimed by the aggregator: early-stage/startup companies, approval case-by-case via submitted company details. No official eligibility criteria published by Mailjet.
How to claim
If it exists, per the aggregator you apply through their deal page (subscription-gated promo code + steps). No official Mailjet application flow found.
Expiry
Unknown; aggregator lists it as a 2026 deal; no official dates.
Gotchas
Not confirmed by any official Mailjet source found today; treat as rumor unless verified directly with Mailjet sales. The reliable startup path is the permanent Free plan + 30-day Premium trial.
Education/student license — NOT offered high confidence
No student or .edu-based free license/credits exist for Mailjet. Searches of mailjet.com and the Help Center found no education program; the only education-adjacent deal is an unverified ~10% 'student discount' on a coupon site (marketingtools.discount) that claims Mailjet 'isn't known' for reliable codes. There IS an official non-profit discount (Help Center article 'Do you have special pricing for non-profits?', ~20% off with documentation per a third-party review), but that is a paid-plan discount, not a free offer for students.
Eligibility
N/A — no student eligibility criteria published by Mailjet. Non-profit status required for the non-profit discount (not student/education).
How to claim
N/A for students — use the Free plan / 30-day Premium trial. Non-profits: contact Mailjet support with documentation for the discount.
Expiry
N/A
Gotchas
Don't budget around the rumored 10% student code; it is not corroborated by official sources.
