# Set Up SMS in Klaviyo

Enable SMS in Klaviyo so you can send Auction Plus notifications by text.

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.

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).
