I have a spreadsheet containing roughly 3,000 contacts. After running it through an automatic verification tool, several addresses came back as either invalid or catch-all. I don’t want to drop these records; I need each questionable address replaced with a valid, working email for the same contact. You will need to research and locate fresh, accurate emails because I do not have alternates on hand. The final file should return with every row intact—names, companies, phone numbers, and any untouched valid emails exactly as they are now—while the problem addresses are updated in place. Please verify each new email so we avoid another bounce cycle. Deliverables • My original spreadsheet returned with an additional “Updated Email” (or similar) column showing the new, validated addresses for every record flagged as invalid or catch-all. • An optional status note for any contact whose correct email could not be found after reasonable effort. • A brief verification summary confirming the method you used to ensure deliverability. Accuracy and data integrity are the priorities; speed is helpful but secondary.

My focus would be on ensuring every problematic address is replaced with a verified, deliverable email while keeping all other contact details intact.
