I’m trying to set up a new Klaviyo account but I'm getting an error message, see below. What does “Invalid Sending Domain”mean? I have a start up fashion brand, launching Shopify site shortly selling waterproof Hem Protectors for denim jeans. Any suggestions or guidance would be appreciated.

Hi ​@SonjayAnn,

May I ask what page you’re on when you see this error? From what you’re describing, it appears as if you’re working on setting up your Branded Sending domain. Is that correct? If so, what are you entering for your root domain, and then what are you selecting your sending domain as?

Or are you seeing this issue somewhere else entirely? Happy to jump in and advise once I have a bit more info!
