Once you're in, you can configure personalized alerts to notify you via email of such things as when:
- A payment has been posted to this account.
- More than ($____ USD) is charged to my card for a single transaction
- My available credit is less than ($ ____USD)
- My available credit is less than ____% of the credit limit.
- My balance reaches ($ ____USD)
- My payment is due in ____days.
- No payment was received for this account.
Also, request a credit limit increase which will give you a better debt-to-credit cushion (which will also help your credit score)
but only if you do not spend more on the card. Stop using the card like Steve suggested and if you must have revolving debt, try to keep your balance/s at no more than 30% to 50% of your credit limit.
