Start With Permission And Suppression
Keep unsubscribed contacts and known bounced addresses out of your send, even if a later verification returns a valid result. Verification describes address evidence; it does not replace permission to contact someone. Preserve your suppression list separately so a fresh spreadsheet import does not accidentally restore contacts who opted out.
Review The Reason, Then Choose The Export
Use the detailed report to understand why each address received its status. Review invalid addresses for a correction at the original source. Keep inconclusive and catch-all results in a separate review group. For a targeted campaign, consider whether role addresses such as sales or support fit your intended audience. Download the relevant group and keep original identifiers so changes can be reconciled with your CRM.
Check The Sending Domain Too
A clean contact list is one part of a healthy email program. Check your sending domain’s authentication, review recent bounce and complaint feedback, and use relevant content for subscribers who expect to hear from you. The free domain and header tools help explain those separate signals. Their results describe the evidence checked, rather than predicting inbox placement.
Keep A Record Of Your Decision
Save the report with its check date and original filename. Download it before the workspace retention window ends. When an old list is reused, review changes in consent, engagement, and mailbox status before sending again. A previous successful check is a snapshot, so compare new results with the earlier report when investigating a change.
