Publishing surface

Drag-and-drop, custom HTML, and rich-text template builders for transactional templates. Bulk endpoint for personalized one-to-one…
Choose Lumail if…
- You want campaigns, graph workflows, capture pages, unlimited stored subscribers, and transactional API/SMTP in one org agents can operate (89 organization-scoped MCP tools plus ChatGPT OAuth plugin, CLI, SDK)
- You send newsletters or lifecycle sequences and do not want a MailerSend + MailerLite split
- You want a 3,000-email free tier with no credit card and overages at $0.60/$0.40 per 1,000 rather than MailerSend's 500-email free cap (card required) and $1.50/$1.30-starting extras
Choose MailerSend if…
- Transactional delivery from application code is the whole product, and you want MailerSend's API, smtp.mailersend.net:587, inbound routing, and template builders
- You already run marketing on MailerLite and want the sibling transactional stack
- You need US/Canada transactional SMS, agency sender identities / many domains, or Professional deliverability extras (DMARC monitors, dedicated IP via support)
Where MailerSend is strong
A real alternative, not a straw man.
MailerSend is MailerLite's transactional sending product: REST API, SMTP relay, templates, inbound routing, optional US/Canada SMS, plus a hosted MCP server and CLI. People pick MailerSend when they need developers and mixed tech/non-tech teams sending transactional email (receipts, password resets, notifications) via API or SMTP, including agencies that need….
- Transactional API + SMTP with templates, webhooks, inbound routing, activity/analytics, and 7 official SDKs
- Hosted MCP (127 named tools) plus CLI, so agents can send and manage domains/templates/suppressions/SMS without wrapping the API
- Volume pricing with a public 50k–2M ladder, Hobby at $7/5k, and agency-oriented Professional limits (domains, sender identities, white-label)
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 MailerSend, stay.
The questions people actually ask
Is Lumail cheaper than MailerSend?
Sometimes. Lumail is $0 for 3,000 emails, then $20 for 40,000. MailerSend'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 MailerSend?
Choose MailerSend when the product you are buying is transactional email from an app (API/SMTP, templates, inbound, SMS). Choose Lumail when newsletters, graph workflows, subscribers, and transactional email should live in one organization agents can operate — MailerSend officially points marketing/newsletters to MailerLite.
Can I migrate from MailerSend 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.
