How to Include Contact Information in an SMS

Last updated at:


Certain jurisdictions require contact information in every commercial electronic message, such as emails and SMS. Per their rules, each message must have: 

  • A valid mailing address (which must be valid for at least 60 days after your message is sent)
  • At least one of the following
    • Email address
    • Web address 
    • Phone number to reach an agent or voice messaging system

Simply adding these details to an SMS takes up too many characters; instead, it's better to add a clearly marked link that provides this information. 

In this article, we run through how to create this link automatically and add it to a Klaviyo SMS or MMS message. This functionality is available for both campaign and flow messages. 

How to Create a Contact Information Link

Create a new SMS or MMS message, adding in any text, links, and images you want. 

Once you're done filling out your message, scroll down to Message Add-ons > Brand Information in the left sidebar.


Navigate to the Compliance tab.

The Company info link option should be enabled by default. Make sure this option is turned on. 

You can preview how this will look in the message by clicking into the message preview window on the right. 


About the Contact Information Link

If you use Klaviyo's built-in functionality, recipients who open the contact information link will not count toward the message's click rate. This way, if you have two links in the message — one going to a product page and the other going to the contact information page — only those who click the link to the product page are counted. 

The contact information link only appears to recipients with an area code where contact information is required, so those in other countries will not see it. The only exception is for the few area codes that the US and Canada share, as there's no way to differentiate what country a phone number belongs to. 

The link pulls the contact information from your account's organization page. To edit this information, navigate to Account > Contact Information > Organization
