Choose Lumail if…
- You want unlimited subscriber storage billed by emails sent, not by list size
- You want 89 org-scoped MCP tools plus a ChatGPT OAuth plugin, CLI, and TypeScript SDK rather than a ~40-tool MCP plus REST only
- You send a large list infrequently: Sender’s paid price follows subscriber count even when you stay under the email cap
Choose Sender if…
- You need SMS, popups, and landing pages in the same dashboard as email
- You want a $0 plan with 2,500 contacts, 15,000 emails, automations, and transactional sending
- You run Shopify/WooCommerce/PrestaShop and want native cart/purchase workflows and ecommerce reports
Where Sender is strong
A real alternative, not a straw man.
Sender is a subscriber-tier email, SMS, and landing-page platform with a 2,500-contact Free Forever plan, visual automations on every plan, and transactional REST API plus SMTP in the same account. People pick Sender when they need small businesses and ecommerce stores that want inexpensive email plus SMS, landing pages, and automations, and can live with subscriber-tier billing..
- Free Forever plan: 2,500 subscribers and 15,000 emails/month with automation, transactional email, forms, and landing pages
- Low paid floor: Standard $10/month monthly or $7/month billed annually at 1,000 subscribers (12,000 emails)
- Transactional REST API and SMTP in the same product as campaigns, on every plan
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 Sender, stay.
The questions people actually ask
Is Lumail cheaper than Sender?
Sometimes. Lumail is $0 for 3,000 emails, then $20 for 40,000. Sender'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 Sender?
Choose Sender when you want a cheap all-in-one SMB suite (email, SMS, forms, landing pages, ecommerce automations) and a generous free tier capped at 2,500 subscribers. Choose Lumail when you want unlimited subscriber storage billed by emails sent, graph workflows on every plan, transactional API/SMTP in the same org, and 89 organization-scoped MCP tools plus a ChatGPT OAuth plugin, CLI, and TypeScript SDK.
Can I migrate from Sender 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.
