Dear [% Company who doesn't check if their mail merging stuff does what it should do or if it suffers from any bugs that make their impersonal e-mail invites even more impersonal %],
I am sorry but I will be otherwise engaged that day and couldn’t really care less if you are going to adept (or even adopt) the name of your mother company and so on and so on. Limited availaballity or not.
Thanks anyway, but no thanks.
