Depending on the merchant, monthly MasterCard statements may be sent out by email or paper statements, explains MasterCard. Most companies mail a statement that indicates the total amount to be charged to a credit card, though some merchants may allow an individual to choose to receive an online statement.
Monthly statements, either via Internet or regular mail, are recommended as a simple and easy option for a thorough record of charges to a MasterCard account. Paper statements often incur a monthly fee. If neither email nor paper statements are desired, merchants may also provide an option to opt out of statements altogether, according to MasterCard.
