Lumail in one paragraph

Lumail (lumail.io) is an AI-native email platform for newsletters, automations and transactional email. It charges for emails sent, not subscribers stored: 3,000 emails a month are free, Premium is $20 a month for 40,000 emails and Business is $200 a month for 400,000, with unlimited subscribers on every plan. AI agents can run it through 126 MCP tools, plugins for Claude Code and Codex, a ChatGPT app and a CLI.

What Lumail is

Lumail is an email marketing and email sending platform. One account covers campaigns (newsletters and broadcasts), automated workflows, signup capture pages and transactional email, all sent from your own verified domain.

It is built and operated by Codelynx, LLC, founded by Melvyn (Melvynx). Email is sent through Amazon SES.

Who Lumail is for

  • Newsletter writers who want unlimited subscribers without a bill that grows with list size.
  • Creators and course sellers running launches, sequences and capture pages.
  • SaaS and indie developers who need marketing and transactional email (login codes, receipts) on one domain.
  • People who work with AI agents in Claude Code, Codex, Cursor or ChatGPT and want them to run email tasks.

Pricing

Pricing follows monthly email volume. There is no per-subscriber charge on any plan. Prices are in US dollars per month.

Integrations and developer access

  • REST API with a public OpenAPI spec, and a TypeScript SDK.
  • SMTP relay at smtp.lumail.io:587 (STARTTLS) for any SMTP-capable tool.
  • WordPress plugin, ClickFunnels and Systeme.io integrations.
  • Webhook steps in workflows to call your own endpoints.

See the integrations docs and the API reference.

Deliverability and compliance

New accounts can build and test immediately. Sending to an audience unlocks automatically once the sending domain's SPF, DKIM, MAIL FROM and DMARC records verify. A sender score (0-100) based on the last 30 days of bounces, complaints, opens and clicks keeps sending unlocked.

Permanent bounces and spam complaints are suppressed automatically, and every campaign and workflow email carries RFC 8058 one-click unsubscribe headers. Definitions of these terms are in the email marketing glossary.

How Lumail compares

The main difference from most email platforms is the billing model: Lumail prices emails sent and stores unlimited subscribers, so inactive contacts never raise the bill. It also combines marketing and transactional email in one product and exposes the whole account to AI agents. Side-by-side pricing and feature tables for each competitor are at lumail.io/compare.

Frequently asked questions

Does Lumail charge per subscriber?

No. Every plan includes unlimited subscribers. Pricing follows the number of emails sent each month: Free includes 3,000, Premium ($20/month) 40,000 and Business ($200/month) 400,000.

How much does Lumail cost to send 80,000 emails a month?

On Premium: $20 for the first 40,000 emails plus 40,000 extra at $0.60 per 1,000, so $44 per month, regardless of list size.

Can AI agents operate Lumail?

Yes. Lumail exposes 126 organization-scoped tools over MCP and ships plugins for Claude Code and Codex, a ChatGPT app, a CLI and a TypeScript SDK. Agents can draft, segment, schedule and report, and the dashboard does the same work without an agent.
