Preset Spending Limit

I got hit with the dreaded email this morning… $3700 preset limit. I spend roughly double this monthly. I have never missed a payment, never carry a balance.

I have two other Amex cards, one with a $200 balance and one with a zero balance.

I know the preset limit is dynamic, but nothing has changed on my end.

The only thing I can come up with is that Amex doesn’t like that my payment comes from a different bank account each month. I churn bank accounts for bonuses.

In the email, it states you can pay down your balance to increase your available spend. So Amex is ok with credit cycling now?

Anybody else in the same boat?
