Hello,

All email notifications are being rejected and not delivered to my email address.

My email administrator indicates that your three IP addresses are blacklisted by several organizations due to their poor reputation, as you can see below:

https://hetrixtools.com/blacklist-check/ [removed by moderator]

I think this would explain all the problems receiving emails from the community.

Hi ​@Vanessa56434 - Thanks for reaching out.

It looks like most of these blacklists are from UCEPROTECT which is regarded as a disreputable blocklist provider. UCEPROTECT is not considered a valid blocklist due to their shady tactics and frequent false positives. Many companies, have globally blocked their servers for this reason. 
 
Our email vendor, Sendgrid, recommends notifying your mailbox provider that this blocklist is impairing your ability to receive legitimate emails.
