Yahoo and AOL recipient error
Fix Yahoo user does not exist bounces
Yahoo's recipient-does-not-exist response is permanent: the named Yahoo or AOL account cannot receive the message. Confirm the address and remove invalid recipients from automated lists.
A representative response is:
554 delivery error: This user doesn't have a yahoo.com account
Yahoo says the delivery will never complete successfully for the invalid account. Do not retry unchanged.
Probable causes
- The username or domain was mistyped.
- The recipient closed or lost the account.
- An imported list contains stale data.
- An alias was removed or never existed.
How to resolve it
- Check spelling and remove surrounding punctuation or spaces.
- Confirm the address with the recipient through another channel.
- Suppress the address from automated delivery after the hard bounce.
- Investigate list provenance if invalid-recipient volume rises.
- Send again only to a newly confirmed address.
