Yes...I read that (...)
In more simple words, it means that a person in charge of offering the service to manage emails for you will decide that (for whatever reason) you won't receive emails from a complete domain name extension. For example, if the .TOP new gTLD is a concerned extension, it means that you won't receive any emails from any email ending in ".top".
TLDs with the worst reputations
- What if you miss that email coming from your new accountant who's using a ".accountant" domain name in its emails?
- What if you miss this email from that startup using a ".agency" because it wants to be identified as an agency online?
- What if you miss ALL THESE EMAILS because your advisor doesn't like new domain name extensions?
One thousand two hundred and twenty seven new domain name extensions were introduced to the Internet. In many of these "new gTLDs", domain name registration volumes are increasing, which also means that more people are using these in their email. If you have a doubt, have a look at this report. So: do you seriously want to take that risk?
There are external advisors who "deal with domain names" and Corporate Registrars who it is the job to provide serious recommendations on how to deal with domain names and emails. They are not so many to be serious and I count five that I would recommend. On that list, none of them would ever - never - suggest their client to block a complete Top-Level Domain from sending emails.
And by the way
I have a client who uses a ".top" domain name for his website and decision was taken to use a ".top" because it matches with the name of the company. My client is fully satisfied with this: he even shortened his domain name changing to a ".top" and now redirects the ".com to the ".top", as well as emails.
