Graham Cluely:

All very sensible. And a good example of why, in the past, I have recommended MailChimp to organisations and individuals wishing to send out legitimate email newsletters.
 
 Only problem is… after years of protecting internet users from unwanted newsletter subscriptions, MailChimp has had a change of heart.
 
 Last week it quietly (I only found out by logging into my account, I never – ironically – received an email advisory from them) revealed that it would be switching its customers’ mailing lists to “single opt-in” rather than “double opt-in”.
