Where Mailjet is strong
A real alternative, not a straw man.
Mailjet is a volume-priced email service that combines a collaborative campaign editor with transactional sending by API and SMTP, hosted in the EU. People pick Mailjet when they need teams that want marketing and transactional email in one EU-hosted service.
- Volume-based plans with unlimited contacts from Essential
- Marketing and transactional email on one platform, with API, SMTP, and webhooks
- EU data centers with GDPR, ISO 27001, and SOC 2 positioning
Don't trust the table. Run one journey.
Checklists lie by flattening the work. Build one real path: a trigger, a wait, a branch, a goal, an exit. Then open one subscriber and see what actually happened. That tells you more than any feature row.
- 1. Import a small, consented sample. Not the whole list.
- 2. Recreate one campaign and the audience it actually hits.
- 3. Publish one automation with a goal you can measure.
- 4. Fire a test and read every event on one person.
- 5. Compare the weekly work, not the setup afternoon.
Try it on a real send
Keep the whole list. Pay when you send.
3,000 emails free, no card. Rebuild one campaign, one workflow, and one transactional message before you move anyone. If it feels worse than Mailjet, stay.
The questions people actually ask
Is Lumail cheaper than Mailjet?
Sometimes. Lumail is $0 for 3,000 emails, then $20 for 40,000. Mailjet's number only makes sense after you know what they cap: contacts, seats, a daily send limit, or a feature they hide behind a paid plan. Read the honest take above, then price a normal month and a launch month on both pages.
What is the main difference between Lumail and Mailjet?
Choose Mailjet for one EU-hosted service for marketing and transactional email with a collaborative editor. Choose Lumail when agents should operate the whole platform and you want unlimited subscribers plus workflows on every plan.
Can I migrate from Mailjet to Lumail?
Yes. Don't move the whole list on day one. Export a small consented sample, rebuild one campaign and one automation, authenticate your domain, then watch one subscriber go through the run. If that feels right, move the rest.
