I joined OVO mid-Dec. I receive an email each month with the Subject Your latest OVO statement on the anniversary date of me joining; ie 16th Jan, 16th Feb.
The embedded link prompts me to logon to My OVO to view the Statement itself. Ie it's not attached to the email. I must use my password to retrive it.
You can choose to have your bill every month or every 3 months.
