If you have chosen a monthly contract your payment will be attempted on the same day as when you originally joined Mettrr. So, if you signed up on September 3rd you will be charged on the 3rd of each month.
The only exception to this is if you are a monthly customer and also have a mailbox. Since you probably registered your mailbox with us on a different day to when you first joined Mettrr, it might not be the same payment date as your website charge.
So if you joined us on September 3rd but bought a mailbox on September 6th you will be charged twice each month, once on the 3rd for your website and again on the 6th for your mailbox.
If you pay Mettrr annually we charge you once a year for your website. The same applies for any other products with a recurring charge, like a mailbox.
