Learn how to enable SMS in Klaviyo.

Before you begin

You must turn on SMS before you can do any of the following:

  • Collect SMS subscribers
  • Import SMS contacts
  • Send SMS or MMS messages

You must also set up your sending number. This can be a:

  • Toll-free number or short code for the US and Canada
  • Branded sender ID or long code for Australia
  • Branded sender ID, long code, or short code for UK
  • Short code for New Zealand

Klaviyo will provide you with a toll-free number and branded sender ID; you simply have to complete the SMS wizard to get these numbers. If you want to use another number, finish this setup process first so you can start collecting consent and then request the other number. For a comparison of the numbers, please see:
