How to write a American Express email address
- Start with the person's first and last name as they write it on LinkedIn.
- Apply
{first}.{m}.{last}@aexp.com: Jane Doe becomesjane.q.doe@aexp.com. - If that bounces, try
{first}.{last}@aexp.com, which 45% of the sample uses. - Use @aexp.com, not the website domain (americanexpress.com).
- 5% of addresses didn't follow a name rule (nicknames, added numbers or older aliases), so a guess can be wrong.
- Verify the address before you send, so a wrong guess doesn't bounce and hurt your sender reputation.
