I've just signed up to a new service (company) using my usual practice of giving them a unique email address firstname.lastname@example.org.
I've just received an email stating:
Thank you for registering for an account with [COMPANY].
We would kindly like to inform you that ‘[COMPANY]’ and ‘[COMPANY ALIAS]’ are registered trademarks and therefore should not be used in any e-mail addresses so as to not cause any confusion or misleadingness. For that reason, we kindly ask that you remove the trademark from your email address.
I've got dozens of email addresses like this one, and they're never used for any comms outside of those between me and that company. I like using this system as it quickly identifies any hack/spam/sale of email and allows me to process the emails using a rule. I know others use email@example.com for example for the same purpose.
Can the company compel me to change the email I use. It doesn't hugely matter, I can just give them SomethingElse@mydomain.com. Was interested in people's thoughts.
