Why am I getting Billing failed notifications?

Notification: “You have unpaid invoices. Please update your payment details to initiate a retry.”

The above warning states that your service may be interrupted unless you settle any outstanding balance on your account. This warning may occur if the card added in your account gets declined when we attempt to process the payment at the beginning of a billing cycle. The outstanding balance can be an overage or the regular month-end billing.

Add the correct credit card and make it as Primary, by logging into your Netcore Email API account. Once you add the new card, the outstanding payment processes automatically.

All invoices carry a grace period of 2 days from the date of invoice generation. In case the invoice remains in the unpaid state for 2 days, then the account enters into a frozen state where you are unable to send any new emails.
