StatusIQ subscribers not receiving emails

Why do subscribers not receive email notifications from StatusIQ?

Email notifications are often missed because the domain names or domain IPs from which the emails are sent have not been allowlisted. Whereas IP allowlisting requires frequent updates, a smarter solution is to allowlist the domain name. This ensures that the hostname dynamically resolves to current IPs. Allowlisting domain names is highly recommended to avoid the need to manage a wide range of IP addresses. 
Allowlist the following email sending domains:
  1. mail.site24x7.com
  2. mails.site24x7sp.com
  3. zeptomail.net

Also, add the following email addresses to your email address book:
  1. noreply@site24x7.com
  2. no-reply@mails.site24x7sp.com
Each of the domains and email addresses above has different extensions in different data centers (DCs):
