If you have set email reminders in your account and you aren't receiving emails from Remember The Milk, it's likely that your email provider is treating the reminders as spam.

Try checking your junk or spam folder; if the reminder email is there, mark it as "not spam" so that you will receive reminders in the future.

You might also like to add [email protected] to your contacts or whitelist, so that emails from this address are not rejected or marked as spam.
