How to Prove to a Client That Their Email List Was Cleaned

Proof is a dated report generated from the run, with the client's name on the list and yours on the page. A line in a status email saying "we cleaned it" is a claim. A report with the date, the rows checked and the valid, risky and invalid split is evidence, and it takes a minute to send.

Why clients do not believe verification happened

Verification leaves nothing visible. The client sees fewer people emailed than they sent you, and then replies and meetings. When the number emailed is lower than the number supplied, some clients assume rows were lost. A report answers that before they ask.

What counts as proof

1. A date. Lists decay, so "cleaned" without a date means little.
2. Rows in and rows checked. The two numbers show nothing was dropped silently.
3. The split. Valid, risky and invalid counts.
4. The risky breakdown. What kinds of risky addresses were found, so the number reads as a description, not a failure. See valid, risky and invalid explained.
5. What happens next. Which group is sent, which is held back, when it is checked again.

Using the branded client report

On the Agency plan, the report is built for this. You save your agency's name and logo once, then each list's client report carries them. It comes out three ways:

• Print or save as PDF, to attach to an email or a monthly deck.
• CSV summary, for clients who want it in a spreadsheet.
• Share link, which expires in 7 or 30 days, so you can send a URL instead of an attachment.

Pair it with client workspaces so each report comes from that client's own lists. The full feature list is on the Agency page.

A short cover note to send with it

Keep it plain:

"Attached is the verification report for the March list. We checked every row on the date shown. Valid addresses go in the first campaign; risky ones are held and split by type; invalid ones are not sent. We will verify again before the next campaign."

Do not add accuracy claims or promise inbox placement. The report shows what was checked, which is the honest scope of the work.

What a report cannot show

• It does not guarantee zero bounces. Mailboxes change after the report date.
• It cannot confirm catch-all addresses, because no verifier can. They show as risky.
• It does not measure replies or placement.

Saying so in the cover note builds more trust than leaving it out. For the wider template, see how agencies report list verification to clients.

Next step

If clients ask what they are paying for, a report each month answers it. See the Agency plan or the pricing page.
