I use this tool every single day
I use this tool every single day - sometimes more than once a day. It's my GO TO for finding out DNS, Nameservers, MX servers, TXT whatever - it does it all. Their free stuff works great but for a little more money. you can have them help you fix DMARC and SPF/DKIM etc - they're very very good at DNS (better than me? YES) and fixing issues with delivery!
