What Happens to Your Email List After You Upload It to a Verifier?
On SimpleVerifier, an uploaded list's job and results file are deleted 7 days after you submit it; confirmed mailbox results are cached by address for 14 days; and on paid plans the risky addresses from a finished list are kept for 14 days so you can re-check them. The privacy policy says lists are not used for marketing and are not sold or shared. Those are the numbers; here is how to read them, and what to ask any verifier.
The four places an uploaded list goes
| Where | What is kept | How long (SimpleVerifier) |
|---|---|---|
| Job record and results file | File name, address count, results, the downloadable file | Deleted 7 days after the list is submitted |
| Result cache | Confirmed mailbox results, by address, without your account | 14 days, then deleted |
| Risky rows for a re-check (paid plans) | Only the addresses marked Send with care or Check again later, with earlier status and reason, plus the job record without the results file | 14 days after the list finishes |
| Account record | Your sign-in email and usage records | Until you ask for deletion; see the privacy policy |
Safe and invalid addresses and your other columns are not kept for the re-check. The privacy policy is the source for these periods; read it for the current text.
What this means in practice
- Download the results within 7 days. After that the file is gone and you re-run the list.
- The cache is not your file. It holds a mailbox answer for an address, not your list or any of your columns.
- Your lists are not marketing data. The policy states they are not used for marketing and not sold or shared.
What to ask any verifier
- How long do you keep the uploaded file and the results?
- Do you cache results by address, and for how long?
- Which subprocessors receive the addresses, and where are they?
- Can I delete a job, and how fast?
- Is there a data processing agreement?
SimpleVerifier answers these on its privacy policy, security, subprocessors and DPA pages. If you work with client lists, email verification and GDPR goes through the questions an agency should ask.
Reduce what you upload
Upload only what the check needs: the email column. Remove duplicates first with the duplicate email remover, and leave out columns the check does not use.

Common questions
How long does SimpleVerifier keep my uploaded list?
Verification jobs and results files are deleted 7 days after the list is submitted. On paid plans, the risky addresses from a finished list and its job record, without the results file, are kept for 14 days for re-checks. These periods come from the privacy policy.
Do you use my list for marketing?
No. The privacy policy says lists are not used for marketing and are not sold or shared.
What is the 14-day cache?
Confirmed mailbox results are remembered by address, without your account, for 14 days, so repeat checks of the same address return instantly. They are deleted afterwards.
Where is the verification server?
The subprocessors page lists Contabo as the host of the verification server, in the United States. The page also lists every other subprocessor and what each receives.
Is there a data processing agreement?
Yes. A DPA template is on the DPA page. If you handle personal data of people in the EU or UK for others, such as an agency, read it and the privacy policy before you upload client lists.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
