Is there any rule to create Subdomain name?
I have read setup domain documentation. It recommends with subdomain name “send”(send.klaviyo.com), so what if I use another name?
In past, I used mail.klaviyo.com and it’s worked. Now, I have reset up and after all, status of sending domain show “In progress” and all request can’t reach to.
Can someone explain clearly about setup subdomain and difference of “send” and “mail”?
