If your customer list lives in a spreadsheet, you can upload it to ReviewWheel and invite up to 2,000 past customers per location to leave a review. This is your one-time reactivation campaign — the requests go out gradually, at a natural pace, and they don't count against your monthly send limit.
Save your file as a CSV first
The upload accepts .csv files only — Excel files (.xlsx or .xls) aren't accepted. If your list is in Excel or Google Sheets, that's fine — just save a copy as a CSV first: choose File → Save As in Excel, or File → Download in Google Sheets, and pick CSV. Then upload that file.
What columns to include
Give your file a header row. The only thing that is truly required is one way to reach each customer: a Phone column or an Email column. Either one is enough, and email-only lists import and send just fine. First Name, Last Name, Job Address, and Last Job Date are optional but helpful — a job address can add a pin to your neighborhood map, and dates like 2026-05-14 or 5/14/2026 both read correctly.
Upload and confirm
Open Contacts and choose Add Contacts (a brand-new account lands on this screen automatically). Under Upload a CSV, drag your file in or click to browse. ReviewWheel auto-matches your columns to its fields — check the matches, re-map anything by hand, and look over the preview. Then check the consent box confirming these are your past or current customers who agreed to hear from you, and import.
What the summary tells you
The summary reads like "Imported N contacts, X already existed, Y had no valid phone or email." Duplicates are skipped automatically, rows with no reachable phone or email are skipped, and a row with one good channel and one junk channel still comes in — the bad channel is simply dropped.
Approve, then launch
Every imported contact waits for your approval — nothing sends until you launch. Before you do, you can prune the list: each row's menu has Remove to take someone off, or Do Not Disturb… to silence the channels they have. When you are ready, use Launch Reactivation on the Contacts page — and if your Google listing is connected, pick a pace, Prove It Fast or Steady Build. You can change the pace later.
Prefer even less work? Connecting your field-service software pulls in past customers and keeps sending review requests for future jobs automatically. See "Adding contacts: the three ways."
