I'm trying to send an email to 50 contacts in a group but I get this message come up.

'Your message wasn't sent because there's a daily message limit. But don't worry, we saved it in your Drafts folder. To increase the limit, verify your account.'

When i click Verify, I'm taken to a page requesting a mobile number. when i put my number in and click next i get 'Sorry, we can't do this at the moment. Please try again later.'

I've had this message for nearly a week now?
