Address Verification Failed

Symptom: Address marked as invalid even though it looks correct​

  1. Check for typos in the street number, street name, and city spelling.
  2. Try expanding abbreviations - use "Street" instead of "St" or "Avenue" instead of "Ave."
  3. Confirm the ZIP/postal code matches the city and state.
  4. Add or correct the unit/suite/apartment number if applicable.
  5. Open the recipient (click its row on the list) to see the reason the address was flagged. If you're sure the address is good, click Mark deliverable.

To see every flagged address on a list, switch on Undeliverable only on the list page.

Symptom: All records failing after upload​

  1. View a few failing recipients and confirm address fields were mapped to the correct fields on Match your columns (street, city, state, postal code separate, unless your Address column holds the full address).
  2. Confirm the country field uses the correct 2-letter code (e.g., US, CA).
  3. Export a few failing rows, fix the format manually, and re-upload to a test list to confirm the corrected format passes.
