My team working relentlessly on trying to get our emails sorted out. We prematurely switched to another domain hosting provider where we have to pay for emails. I had unlimited email access at my previous provider. We are still working on sorting this out.
I can resonate with your here Sree. When the email is down, we receive a painful education on DNS. Go thing it only takes MX records 4 - 8 hours to propagate instead of the 24-48 hours for CName and A records. Hope your mail is up soon so you receive those inbound leads this month. Feel free to reach out if you have any other DNS or hosting issues.
