delivered_recently

Your own delivery report confirmed this mailbox

Not a probe result: your account reported the address as delivered within the last 90 days, and a real delivery is better evidence than any handshake.

1 credit as a deliverable answer; the handshake itself is skipped.

What it means

When you send delivery outcomes through the feedback endpoint or an ESP webhook, a delivered report for an address turns later lookups of it into confirmed mailboxes. The probe is skipped, mailbox_exists is true, smtp_checked_at is the delivery time, and the sources list delivery-feedback instead of the SMTP handshake.

Only your own account's reports count. Other customers' outcomes are never used for your verdicts.

What to do

Nothing. Keep reporting outcomes and the share of lookups that needs a paid probe keeps falling.
