# Marketing

Breww integrates with two leading marketing platforms so you can run powerful, targeted email campaigns without manually keeping your contact lists in sync.

* **[Mailchimp](https://breww.com/docs/syncing-to-mailchimp/)** -- Email marketing and automation.
* **[Klaviyo](https://breww.com/docs/syncing-to-klaviyo/)** -- Email and SMS marketing with advanced segmentation and flows.

## What Breww syncs

For every customer (and, optionally, every customer contact) Breww pushes a rich set of fields to your marketing platform. This means you can segment, personalise and automate campaigns using live Breww data without ever needing to export a spreadsheet.

Fields synced include:

* **Identity** -- email address, first name, last name, business name.
* **Relationships** -- customer type, parent company, price book, delivery areas, tags.
* **Location** -- full delivery address plus latitude and longitude, so you can segment by geography or distance.
* **Ordering behaviour** -- last order date, average order value, number of invoiced orders.
* **Order predictions** -- next expected order date, contact-after date, churn probability and overdue probability. These come from Breww's built-in [order predictions and churn risk](https://breww.com/docs/order-predictions-and-churn-risk/) model and let you build truly data-driven campaigns (see the platform-specific guides for segmentation ideas).

## How lists work

In Breww, you decide exactly who gets synced to each list (Mailchimp calls these "audiences"; Klaviyo calls them "lists"):

* **All customers**, or a specific [customer list](https://breww.com/docs/customer-and-lead-lists/) built with a BrewwQL filter.
* **Customers only**, **contacts only**, or **both**.
* Which **tags** you want to sync.

Breww syncs each list automatically every day, and you can trigger an immediate sync from the list management page at any time.

> Breww will never send emails from your Mailchimp or Klaviyo account. The integration only keeps your audience data in sync -- you still design and send campaigns from inside the marketing platform.

The integration is available on all Breww price plans at no extra charge. Head to the platform-specific guide to get started:
