SMS consent new brand

Hi, 

I have just launched my brand and created a database pop up collecting emails and sms. Unfortunately sms is not coming through as verified. Any tips on what could be happening here?

 

Thanks

    Hi ​@mrsippy - here are some possible causes and troubleshooting suggestions:

    1. SMS Consent Not Properly Configured

    • Ensure compliance with TCPA or other regional SMS marketing regulations. Users typically need to explicitly opt in to receive SMS messages (e.g., via checkbox).

    • Double-check whether the popup includes clear language about SMS consent and if it’s being correctly passed to your SMS provider.

    2. Integration with SMS Platform

    • Make sure the form is integrated with Klaviyo, or another SMS provider.

    • Some providers require you to register a brand and campaign

    • If the brand registration or verification is pending, SMS may not be functional yet.

    3. Phone Number Formatting

    • The phone number may not be formatted properly (e.g., missing country code, extra characters).

    • Validate phone numbers at the point of entry using the correct format (e.g., +1 for US).

    4. Platform-Specific Issues

    If this is happening on a specific platform:

    • For Shopify: check if you’re using a third-party popup app (like Privy, Justuno, etc.) and ensure it syncs SMS data to Klaviyo.

    • For Klaviyo: ensure the SMS channel is enabled and that the list is SMS-subscribed.

    5. Confirmation Flow Not Triggered

    • Many platforms require users to confirm SMS consent through a double opt-in message.

    • If the confirmation message isn’t sending or being confirmed, the user will not be marked as “verified.”

    Hi ​@mrsippy,

    Let us know if Zac’s answer helped solve the issue! If you still need assistance, we can take a deeper look to determine why consent is being captured, and what the fix will most likely be.
