Zubaer How do I find my selector?
Use the selector in your mail provider’s setup instructions or the s= value in a DKIM-Signature header from a sent message. Use that signature’s d= signing domain for the DNS lookup.

How to use Email Deliverability Checker
Is a published record enough?
A published SPF policy or DKIM key does not prove every message passes. Compare an actual received message and check whether the receiving service reported SPF, DKIM and DMARC passes.
Will this tell me if a message lands in spam?
This report checks visible DNS and displays reported authentication results. It does not send test mail, inspect inbox placement, or check sender reputation.
