# Set Up SMS in Klaviyo

Auction Plus can send events to Klaviyo, but SMS sending is configured in Klaviyo itself.

Before you start:

* Connect the [Klaviyo Integration](/integrations/klaviyo.md).
* Complete Klaviyo's SMS setup before building flows.
* Enable [bidder registration](/customers-and-bidders/bidder-registration-and-approval.md) to collect customer phone numbers.

## Set up SMS in Klaviyo

Follow Klaviyo's official guide to enable SMS for your account:

[Getting started with SMS for new senders](https://help.klaviyo.com/hc/en-us/articles/4404274419355)

Klaviyo walks you through:

* enabling SMS for your account
* choosing your sending number
* completing any required compliance steps

***

## Next steps

After SMS is enabled in Klaviyo, you can start building Auction Plus text notifications.

Recommended next steps:

* Build an automated outbid flow with [Set Up Outbid SMS Notifications in Klaviyo](/integrations/set-up-outbid-sms-notifications-in-klaviyo.md).
* Review available event fields in [Klaviyo Event Reference](/integrations/klaviyo-events.md).
