I can’t help being surprised to read the mail you quote and note the English being, let’s say… Limited. (No pun intended. Honestly.)
StartCom is apparently registered as an ‘Ltd’ company and I would have thought they would be able to compose a generic mail, mass distributed to a high number of their existing and potential future clients written in an English containing far less grammatical errors.
Have you been able to confirm the message was actually sent by StartCom Ltd. ?
Personally, I would check before acting upon the message for the benefit of my own sites.
(For the records. My own English is far from perfect. English is just my third language. But I still think that if I worked for StartCom Ltd. and if I had the task to compose an official generic message to the client base, I would take the time to re-read my message more than once before hitting the ‘Send’ button. The message quoted above looks like a ‘first draft’.)
