And that is the issue. MyUS doesn’t normally accept ordinary mail (letters) from the United States Postal Service, whereas courier-delivered items (i.e., with tracking) are okay.
So, the higher-end cards, which are courier-delivered from Amex to My US, are okay. The others, that are just sent in an envelope through the USPS mail may not make it into the MyUS system. I wonder whether Amex would send out the enveloped cards by courier if requested (i.e., “delivery to be expedited”)?
The MyUS system is not perfect, as a test envelope (containing an old expired credit card) that I sent to my suite from Oz, 12 months ago, actually made it back to me weeks later, even though I was not subscribed to the mail option. So, anything’s possible I guess. Some may get through while others don’t.
