Why am I getting an error message when setting up SMS?

Hey there, 

 

I keep getting an error message when I try and set up SMS messaging in Klaviyo. For some reason I was able to set it all up during the tutorial but I was never able to verify a phone number to actually use. 

I try and redo it all now and I am unable to get past a certain point in signing up. 

 

This is the error I keep receiving . I get it after filling out the company information part of the setup.

 

Any help is appreciated!

 

Thank you

    Hi ​@oracle01,

    This issue can happen sometimes if your Organization name contains too many numbers or invalid characters. Your organization name is used to create a Branded Sender ID (one of the mobile sending numbers), so I’d recommend ensuring that there are no characters like a trademark/copyright symbol in your organization name.

    Additionally, after you’ve ruled this out, could you try setting this up in incognito mode, to see if you’re dealing with a browser issue? Finally, if that doesn’t work, I’d encourage you to reach out to Klaviyo.com/support, and our support team can take a closer look at this for you to see why this is happening.
