American Express Mail Offers and RSVP Codes

American Express targeted card invitations often include an RSVP code on the letter or email.

Respond only on an americanexpress.com page from your offer. An RSVP code is not final approval.

Separate option – personal loan rates

Upstart is for personal loans, not an Amex card application. Compare personal loan rates without affecting your credit score¹.

Compare Rates

On the Upstart platform, you could receive offers from lenders.

Affiliate link. LendMail may earn a commission if you apply and are approved. Not all applicants approved. Upstart Network, Inc. (NMLS #936133) is not a lender. All loans on its marketplace are made by regulated financial institutions.

¹ When you check your rate, we check your credit report. This initial (soft) inquiry will not affect your credit score. If you accept your rate and proceed with your application, we do another (hard) credit inquiry that will impact your credit score. If you take out a loan, repayment information may be reported to the credit bureaus.

This brand page covers a credit card (or bank card) mail path. Upstart is a personal-loan marketplace — not the same as applying for that brand’s card.

Response URL (what we verified)

Verified: americanexpress.com hosts a mail-offer RSVP path at /us/credit-cards/dtw-landing/rsvp-code-mail-offer (HTTP 200 on the Amex domain). Amex also offers a soft-pull check-for-offers flow at /us/credit-cards/check-for-offers/. Some targeted Amex landings are product-specific; use the link or URL on your piece when it differs.

Code / field label (what we verified)

Amex’s mail-offer vocabulary centers on an “RSVP code.” Targeted Amex offer pages have asked applicants to enter the RSVP code from the offer (and, on some landings, additional identity digits). Field requirements can vary by offer page — follow the form on your letter’s URL.

RSVP code vs. Amex Offers

An RSVP code on a mail or email invitation is for applying to a Card offer.

“Amex Offers” inside a logged-in account are merchant discounts on an existing Card — a different product. Don’t confuse the two.

Before you apply

Confirm the browser bar shows americanexpress.com.
Copy the RSVP code exactly (watch 0 vs O).
Read annual fee, APR, and welcome-offer rules on the offer page.
Remember: submitting an application usually means a hard pull.

Before you apply

Pre-approved ≠ approved. Final approval happens after the issuer reviews a full application.
Hard pull: submitting a card or loan application usually triggers a hard credit inquiry.
Compare APR, fees, rewards, and total cost on the issuer’s own page before you accept.
LendMail never asks for your offer code, password, or Social Security number.

FAQ

What is an Amex RSVP code?

It’s the code Amex prints on many targeted Card invitations so you can open that specific offer online. It does not guarantee approval.

Where do I enter an Amex RSVP code?

On the official americanexpress.com page linked from your mailer or email. Amex also maintains a mail-offer RSVP landing under /us/credit-cards/dtw-landing/rsvp-code-mail-offer.

Is LendMail affiliated with American Express?

No. LendMail is an independent guide and does not collect Amex RSVP codes.
