Guy H. Zerobounce does not validate catch-all emails, so it will mark "invalid" every catch-all email even if the email is good (it's just that they can't validate it, not that it's invalid).
Switching your validation provider in the waterfall settings to Findymail should help you validate more emails as it supports catch-all validation
Hey Guy, thanks for reaching out. These were invalidated by Zerobounce, and we don’t revalidate the same emails. If it's invalid, it's not passed in the last column.
Either way, do you mind sending the link (url) to the table so we can take a look?
Guy H. You probably had one of these turned on?
Essentially, if you turn it on, if an email provider finds an email, but zerobounce deems that it's invalid, it will not return the email
Email waterfalls populate results in the final validated email column, not intermediate provider columns.
The validation columns are hidden by default to keep your table tidy, but they exist behind the scenes. You can unhide these validation columns through the Columns Panel to see the detailed validation steps and understand why emails appear in specific columns.
If emails appear in unexpected columns, check if they failed validation - the waterfall continues running when emails are found but fail validation checks.
