Think through before switching your domain hosting provider
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.
