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

Iterable is an enterprise customer engagement platform that runs email, SMS, push, in-app, and WhatsApp journeys under a custom contract; Lumail is a self-serve email platform with published prices, built so AI agents and developers can operate it. They meet on email. Iterable is for large brands orchestrating many channels with an implementation team. Lumail is for teams whose channel is email.

The choice is mostly about scope and buying motion. Iterable is bought through a demo and a negotiated order. Lumail is something you sign up for and start using the same day. Iterable facts here come from its official pricing page as of August 2026, which is a contact form rather than a price list; check with sales before you buy.

Lumail vs Iterable at a glance

Lumail's current plans are on the Lumail pricing page.

Choose Lumail if AI agents should operate your email

Iterable builds AI into the product through Nova, which helps with templates, journeys, experiments, and send-time decisions. It also publishes an open-source MCP server in beta that maps its REST API into tools, read-only by default, which you install and run yourself. There is no hosted MCP server or ChatGPT app.

Lumail exposes 89 organization-scoped MCP tools covering campaigns, subscribers, tags, segments, workflows, templates, analytics, and transactional sending. The same operations run in ChatGPT, Claude, Claude Code, and Cursor, and through a CLI, a TypeScript SDK, and a REST API. An agent works on your real audience and real workflow state.

In practice you can ask an assistant to:

• draft next week's campaign from an approved brief and template;
• build or edit a workflow graph and explain a subscriber's path;
• tag and segment subscribers before a targeted send;
• send a receipt or password reset from the same account;
• summarize last month's results without exporting a CSV.

You keep consequential actions behind human approval and finish drafts in the visual editor.

Choose Lumail if email is your channel, you want to start without a sales cycle, or you want agents connected to a hosted, organization-scoped surface.

Choose Iterable if you run lifecycle messaging across every channel

Iterable is built for enterprise consumer brands, and its depth is in orchestration. It sends email, SMS, push, web push, in-app, embedded messages, WhatsApp, and even TV app messages from one platform.

Choose Iterable if:

• you need email together with SMS, push, in-app, and WhatsApp in marketer-owned journeys;
• you want AI decisioning for send time, channel, and frequency, plus predictive audiences;
• you already run a data warehouse and want catalogs, mobile SDKs, and a dedicated implementation team.

Lumail does not try to be an omnichannel platform. It has no SMS, push, or in-app messaging. Its focus is the email system: audiences, campaigns, graph workflows, transactional delivery, and the programmable surface around them.

Compare the pricing models, not the starting prices

Iterable does not list plans or prices. Its pricing page asks for your email volume and books a call. Contracts set limits on users, messages per channel, custom events, and catalog size, and usage above those limits is billed according to the agreement.

The only public Iterable price is an AWS Marketplace listing: $115,000 for 12 months, covering 5 million users, 75 million emails, two dedicated IPs, 750,000 US text messages, and 250 million push notifications.

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

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

A worked example

Take the email volume in that marketplace listing: 75 million emails a year, about 6.25 million a month.

On Lumail, that is Business: $200 for the first 400,000 emails, plus 5.85 million at $0.40 per 1,000, which is $2,340. That makes $2,540 a month, or $30,480 for the year.

On Iterable, the marketplace bundle is $115,000 for the year. It also covers 5 million users, SMS, push, and dedicated IPs, so it is not a like-for-like email price. It does show the scale Iterable is priced for.

If you need those other channels, compare Iterable with other engagement platforms. If you only need email, Lumail's published rates let you price your own volume without a call.

Compare automation and transactional email

Iterable's Journeys, built in its Studio, combine messages, delays, filters, profile updates, and integrations such as webhooks and ad audiences. Campaigns can be one-off blasts or triggered by an API call or a journey. Nova can suggest journeys and experiments, with a person approving the changes.

Lumail's workflow engine is graph-based and included on every plan, including Free. It supports subscriber, tag, event, schedule, and manual triggers; email, wait, action, and webhook steps; condition and weighted branches; and goals and exit rules. The same graph is readable and editable from the app, MCP, CLI, SDK, and API.

Both handle transactional email, in different ways. Iterable sends receipts and shipping confirmations through transactional channels, triggered by its API or by a journey, with no SMTP relay. Lumail sends transactional messages from the same organization as campaigns, through the API or SMTP relay at smtp.lumail.io:587 with STARTTLS.

Migrating from Iterable to Lumail

Most teams moving from Iterable move the email program and keep other channels elsewhere.

1. Export users and suppressions. Use Iterable's export jobs to pull users with email consent and unsubscribes. Import suppressions as well as actives.
2. Authenticate your sending domain. Configure SPF and DKIM in Lumail and verify the domain. Keep Iterable live while DNS propagates.
3. Rebuild one journey as a workflow. Recreate the email steps of a key journey as a graph workflow, then test every branch with test subscribers.
4. Move transactional email. Switch triggered-campaign API calls to the Lumail API or SMTP relay, and confirm delivery before cutting over.
5. Decide what stays. SMS, push, in-app, and WhatsApp programs have no Lumail equivalent. Keep them on Iterable or another specialist.
