and then the probably ok?

I don;' want to have to filter a 100k row spreadsheet by a number percentage to create another sheet to download to import in to my mailer.

The reasons are all very interesting and all that (yawn), but ultimately I just want to know who I can mail and who I can't.

This is how all other list hygiene apps work that I have used.

ALSO I do want to verify 1 million emails in one go and then just trickle sin the months to come.
Can we work something out?

Many thanks.
