If you see the message “Email address is on the blacklist and cannot receive emails” on a customer profile, it means this customer is indeed not receiving any emails from your Optios account.
There are several reasons why your customer's email address might end up on the blacklist.
The email address is incorrect.
Always double-check (with the customer) if the address is correct. Is there a typo in the address? Are all the characters correct?The customer is using their own domain name.
The last part of an email address is the domain name. This could be that of a business or personal domain, e.g., belinda@topkappers.be or stijn@nmbs.be.
These custom domain names often block emails coming from servers.
We recommend asking the customer to use a different email address with a general domain name, e.g., anna@telenet.be or stijn@gmail.com.Your customer (or their mailbox) has blocked Optios emails.
An extra strict filter on the mailbox has blocked email traffic from Optios. Or, in the past, the customer themselves has (accidentally) blocked Optios.
Has the customer confirmed that the email address is correct? It’s not their own domain name? Then please send us a message with their name and email address.
Customers on the blacklist can only be removed by Optios if the blocking was due to a spam complaint!
