There is more than one version of americanexpress.com, but for my personal cards this sequence works:
- americanexpress.com
- login
- Update Contact Information
- Account Alerts
- Manage Account Alerts
There are several categories of Alerts. Be sure to scroll down to click [Save] before leaving the page.
Yea I was looking under "manage account alerts" on the website, yet I only have checkbox options for email or text, not push.
