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 Klaviyo, stay.
The questions people actually ask
Is Lumail cheaper than Klaviyo?
Sometimes. Lumail is $0 for 3,000 emails, then $20 for 40,000. Klaviyo'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 Klaviyo?
Choose Klaviyo if you run an online store and want email, SMS, catalog data, and visual flows in one place. Choose Lumail for unlimited subscribers billed by emails sent, graph workflows, transactional email, and 89 MCP tools.
Can I migrate from Klaviyo 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.
