In this episode i have drawn some lessons from the ZOHO Fiasco (https://www.theregister.co.uk/2018/09/24/zoho_domain_snafu/)
I have undergone similar embarrasment as Zoho and had to make repairs; therefore i am able to share the first hand experience of having a domain blocked and blacklisted. Start-ups can learn what to do to avoid having their domains blocked or blacklisted.
