Field-tested by my team. Address quality is the strongest column in the file. Bought it as the seed list for a fleet telematics provider outbound push in Canada. One column I'd add next refresh: secondary email.
Thanks for the honest feedback, we hear you on the gaps — the next monthly refresh tightens those exact columns. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
