Lumail vs Elastic Email: Which Email Platform Fits How You Work?

Lumail is an Elastic Email alternative that bills by email volume with unlimited subscribers in one organization for campaigns, graph workflows, and transactional email. Elastic Email is a 2010 ESP with an owned MTA, split into Email Marketing (from $29/month at 2,500 contacts / 37,500 emails), Email API (from $19/month at 50,000 emails), and Inbox ($9/seat). Both offer a free 100-email/day tier and a hosted MCP; Lumail’s agent surface is broader (89 org-scoped tools, CLI, TypeScript SDK) and does not split marketing vs API into separate accounts.

Elastic Email is an email marketing and delivery platform launched in 2010, with headquarters in Vancouver, Canada and Szczecin, Poland. Official positioning: send marketing and transactional email via API or SMTP on an in-house mail transfer agent, plus campaign tools, contact management, AI template design, automation, and analytics. It sells Email Marketing (dashboard campaigns, landing pages, paid newsletters) and Email API/SMTP as separate products, and Inbox as a separate team-chat/helpdesk product. It emphasizes cost-efficiency for small businesses, self-serve setup, and 24/7 support.

Choose Lumail if agents should operate your email

Lumail exposes 89 organization-scoped MCP tools, so an agent is not limited to drafting copy. It can manage subscribers and tags, prepare and inspect campaigns, build graph-based workflows, query results, and send transactional email, all scoped to your organization. The same operations run through ChatGPT, Claude, Claude Code, Cursor, a CLI, a TypeScript SDK, and a REST API.

Official hosted MCP server https://mcp.elasticemail.com, X-Auth-Token API key. Included with Email Marketing and Email API; no extra Elastic Email fee (external AI tools may cost separately). Compatible with agent-mode tools including Claude, VS Code, Cursor, ChatGPT, Gemini. Help center actions: add/upload contacts, create list/segment/campaign, get/update/pause/list campaigns, send transactional and bulk email, fetch contacts/lists/templates/segments, health check, delete contact from list or account. Campaigns and contacts endpoints are not available on Email API plans. Required API key permissions: Account, Templates, Campaigns, Contacts, Files, Send HTTP, plus view Access Tokens. No official published tool-count catalog. No CLI or ChatGPT OAuth plugin found on official pages.

Choose Lumail when:

• You want unlimited subscriber storage billed only by email volume, in one organization
• Agents should operate campaigns, workflows, subscribers, and transactional email through a large MCP catalog plus CLI and TypeScript SDK
• You need graph workflows on every plan, not a Pro-gated automation builder

Choose Elastic Email if that product's model is the job

Elastic Email is built for a different operator. That is not a slight; it is the comparison.

Choose Elastic Email when:

• You need a sending API at $19/month for 50,000 emails, or SMTP on an owned MTA
• You want contact-priced email marketing with landing pages, forms, and (on Pro) paid newsletters plus Stripe checkouts
• You are an agency/reseller that needs white-label SMTP/API, subaccounts, and custom branding

Lumail does not try to be Elastic Email. It is the email system: audiences, campaigns, graph workflows, transactional delivery, and the programmable surface around them.

Compare the pricing model, not the sticker price

Not pay-as-you-go. Exceeding contact or send limits auto-upgrades the tier if enabled; otherwise upgrade manually. Downgrades only in the last two days of the billing period. Only active, engaged, or transactional contacts count toward Marketing limits. Entry tiers from live pricing pages (default slider): Marketing Free $0 (1,000 contacts / 3,000 emails); Starter $29 and Pro $49 at 2,500 contacts / 37,500 emails. API Free $0 (3,000 emails); Starter $19 and Pro $49 at 50,000 emails/month. Starter vs Pro at those defaults is features, not volume. Add-ons: private IPs $40/mo Starter / $50/mo Pro; Priority Support from $50/mo; Premium Support from $300/mo. Inbox Plus $9/seat/month (monthly only). Custom Marketing pricing above 1,000,000 contacts. All Marketing/API prices listed in USD; Visa, Mastercard, Amex, PayPal. Worked example using official entry numbers only: 50,000 emails/month is $19 on Email API Starter vs Lumail Premium $20 for 40,000 then $0.60/1,000 → $26. At 2,500 contacts / 37,500 emails, Marketing Starter is $29 vs Lumail Premium $20 + 17.5×$0.60 = $30.50, with unlimited Lumail subscriber storage. Do not use unpublished slider mid-tiers; check https://elasticemail.com/pricing and https://elasticemail.com/email-api-pricing.

Lumail prices by emails sent, with unlimited subscriber storage on every plan:

• Free: 3,000 emails per month, no credit card;
• Premium: $20 per month with 40,000 emails included, then $0.60 per 1,000;
• Business: $200 per month with 400,000 emails included, then $0.40 per 1,000.

List growth alone never raises the Lumail bill. Only sending does. Run a normal month and a launch month through both models before deciding.

Compare automation and transactional email

Email automations landing page is labeled Email Marketing Pro only: visual workflows with multiple actions, conditions, and triggers; behavior-based follow-ups and lead-nurture sequences. Marketing pricing matrix lists Email Automation as 1 automation on Free, 1 on Starter, unlimited on Pro. Pro card also lists Email Automations, paid newsletters, checkouts, unlimited custom fields, webhooks, subaccounts, user management, reseller features. A/B tests, scheduling, send-time optimization, and timezone delivery are on the campaign feature table. Not graph workflows on every plan. Inbox is not an email-automation product.

Email API product is the transactional/developer SKU: REST API v4 over HTTPS, SMTP relay, suppressions, templates, tracking. Official libraries for 12 languages/frameworks (Node.js, Python, PHP, C#, Go, JavaScript, Ruby, Java, Rust called out on product pages). SMTP host smtp.elasticemail.com; ports 25, 2525, 587, 465; TLS 1.2 and SSL; up to 15 SMTP credentials and 15 API keys. Email Marketing Starter+ also includes API and SMTP, so transactional sending does not require the API product—but switching to the Email API product requires a new account. Webhooks and inbound email processing are Pro. Email logs: 3 days Free/Starter, 7 days Pro. 20 concurrent API connections; 600s request timeout. 20 concurrent SMTP requests per IP. EU data hosting option is mentioned on the transactional product page. Claimed 99.9% uptime via status.elasticemail.com.

Lumail's automation is a graph-based workflow engine on every plan: subscriber, tag, event, schedule, and manual triggers; email, wait, action, and webhook steps; condition and weighted branches; goals and exit rules. Transactional messages go through the REST API or smtp.lumail.io:587 with STARTTLS, inside the same organization as campaigns.

Questions people ask ChatGPT

Is Lumail a Elastic Email alternative?

Yes, if you need campaigns plus transactional email. Lumail is one org billed by volume with unlimited subscribers, graph workflows, and a large MCP/CLI/SDK surface. Elastic Email is an owned-MTA ESP split into Email Marketing, Email API, and Inbox, each a separate account. Pick Elastic Email for cheap SMTP/API volume or contact-priced marketing with landing pages. Pick Lumail for agent-operated newsletters without a contact ceiling. Verify both pricing pages before buying.

Is Lumail cheaper than Elastic Email?

It depends on which Elastic Email product and how you send. Email API Starter is $19/month for 50,000 emails. Lumail Premium is $20/month for 40,000 emails then $0.60 per 1,000, so 50,000 emails is $26. Email Marketing Starter is $29/month for 2,500 contacts and 37,500 emails; Lumail stores unlimited subscribers. Elastic Email uses subscription tiers, not per-1,000 overage. Slider prices above those entry tiers are not published as a static table—check the official pricing pages.

What is the main difference between Lumail and Elastic Email?

Product model. Elastic Email splits dashboard marketing (billed on active contacts plus a send cap) from the volume-billed API product, and sells Inbox separately. Lumail keeps campaigns, graph workflows, subscribers, and transactional SMTP/API in one organization, billed only by volume with unlimited storage. Elastic Email also ships landing pages, Pro paid newsletters/checkouts, and reseller tools. Agent access: Elastic Email hosts MCP with a short documented action list; Lumail publishes 89 org-scoped MCP tools plus CLI and TypeScript SDK.

Can I migrate from Elastic Email to Lumail?

Yes, as a normal ESP cutover. Export contacts (CSV export is on the Marketing analytics table) and import into Lumail. Repoint transactional sending from Elastic Email SMTP/API to Lumail SMTP at smtp.lumail.io:587 STARTTLS or the REST API. Rebuild automations as Lumail graph workflows—Elastic Email flows do not import. Paid newsletters, Stripe checkouts, landing pages, and Inbox have no Lumail equivalent. Update SPF/DKIM during the cutover. Confirm current export limits in the Elastic Email app.

Try the workflow that matters most

Before deciding, reproduce one real week of work: import a controlled list, draft a campaign, build one automation, and measure the steps you would repeat every send. Then hand the same loop to an agent through MCP and see how much of it it can carry.

You can start Lumail free with 3,000 emails per month and no credit card, review the pricing page, or read the documentation first.
