Iterable

Category: Email/Newsletter

Behavioural messaging with real EU hosting on request.

Iterable is a cross-channel marketing platform for email, push, in-app, SMS and web, built around a visual journey builder working on your own event and user data. It handles segmentation, experimentation, catalogue-driven personalisation and send-time optimisation, and is typically chosen by companies whose messaging needs to respond to product behaviour rather than list membership. In 2026 it launched Nova, an agent layer that builds, personalises, tests and optimises campaigns, alongside anonymous audience activation and a governance toolkit. There is a first-party MCP server, but note carefully what it is: open-source and self-hosted rather than a hosted endpoint, explicitly labelled beta, with personally identifiable data, writes and sends all disabled unless you deliberately enable them, and beta terms reserving the right to discontinue it without notice.

Our verdict

A strong platform in a crowded space, and the journey builder handles genuinely complex branching without becoming unreadable, which is harder than it sounds. The safety design on its MCP server is commendable: personally identifiable data, write access and sending are all off by default and must be explicitly enabled, which is exactly right for a tool that can message your whole customer base. That said, it is self-hosted, beta, and carries terms allowing discontinuation without notice, so do not build production workflows on it. The most important practical point for UK readers is hosting. A European data centre in Ireland exists with full feature parity and no US transfer, but it is determined by your contract rather than your location, and migration is not offered afterwards. Specify it at signature or you will be on US infrastructure permanently. It also has no native customer data platform, so unification happens upstream, and pricing is entirely quote-based with no trial.

Best for: Consumer subscription and marketplace businesses with real event data who need European hosting and will negotiate it at contract.
