Tearing my hair out trying to resolve this … any help appreciated.
We have two websites built on Shopify (B2B and B2C), with one being the subdomain of the other (e.g. https://wholesale.company.com). Each Shopify is linked to a Klaviyo account, which has been fine for us so far.
When trying to set up branded sending domains, I’m only able to activate it on our B2B Klaviyo account. I get the following error message: “There is a maximum of one sending subdomain per domain level. For more help, please contact Klaviyo support.” I tried different variations for each Klaviyo account (i.e. mail.company.com and send.company.com) but still receive the error.
Today, I removed the branded sending domain from the B2B account and set up the branded sending domain with the subdomain included (i.e. send.wholesale.company.com). This activated okay, but when I went to add send.company.com to the B2C Klaviyo, I get the same error.
Our next best option is to move one of the accounts over to Mailchimp, but we’d prefer to keep everything with Klaviyo.
