# The best customer engagement and lifecycle messaging platforms

> Platforms that hold behavioural customer data and send messages across several channels off the back of it, branching on what somebody did rather than on a list they sit in. The heavier end of messaging, where the product is the segmentation as much as the sending.

## Frequently asked questions

### How is this different from email marketing?

Mostly where the data comes from. An email tool segments the list you upload. An engagement platform segments what people did in your product, which is why these carry event ingestion and usually a heavier integration.

### Why is nothing ranked here?

We have not tested anything in this category yet, so the list is alphabetical and says so. It stays that way until a bench exists and products have been through it.
