Mailjet combines marketing emails with transactional sending, but paid plans start at $15/month and the free tier's 200-email-per-day cap can feel tight. Depending on whether you need marketing blasts or developer-grade transactional sending, there are free tools that cover each side. Here are the best free Mailjet alternatives.

MailerLite free gives you 1,000 subscribers, 12,000 emails per month, automation, landing pages, and a website builder. For the marketing side of Mailjet, MailerLite's free tier is more generous and its editor is friendlier for non-developers.
Brevo free includes unlimited contacts, 300 emails per day shared between marketing and transactional sends, plus a drag-and-drop editor. It is the closest all-in-one free replacement for Mailjet because it covers both campaign and API sending on the same plan.
SendGrid's free plan allows 100 emails per day with full API access, webhooks, and delivery analytics — enough for testing and low-volume transactional mail. For the developer side of Mailjet, SendGrid is the industry-standard free option.
Mailgun's free trial tier historically includes a few thousand emails per month with a full API, logs, and deliverability tools. For developers needing reliable transactional delivery with webhooks and analytics, Mailgun's free tier is a solid Mailjet alternative.
Amazon SES offers a free tier of 3,000 emails per month for 12 months, then charges roughly $0.10 per 1,000 emails — far below Mailjet's pricing. It is the lowest-cost way to send transactional email at scale, with full API and SMTP support.
Mailjet costs $15-95/month ($180-1,140/year). That is $180-1,140/year every year — money that could go toward building an AI-powered income stream instead. Our case studies show that you can build complete revenue-generating systems using only free tools.
