What is RefreshList?
RefreshList is email list cleaning and verification software that helps businesses inspect email databases before outreach. Users can assess list structure, identify duplicates and malformed records before verification, classify eligible email addresses, preserve original columns, and download useful result groups.

RefreshList is new. Our experience cleaning email data is not.
That experience shaped what we built: visible uncertainty, preserved data, clear charging, and results you can understand.
This is our team’s experience, not an independently measured accuracy benchmark or a claim that RefreshList launched in 2018.

RIGHT ANSWER IS
“WE DON’T KNOW.”
Some receiving systems do not provide enough evidence for a conclusive result. RefreshList keeps result language precise and evidence-based.
UNKNOWN stays UNKNOWN. Results are reported with clear server-response explanations in the result guide.

SIX SIGNALS.
NO FALSE CERTAINTY.
Uncertainty should be visible — not hidden behind a confidence-looking number.
ERROR
The server says delivery failed, but gave no information about email existence or availability.
SMTP ERROR
The SMTP server returned an invalid response or an internal error.
SMTP PROTOCOL
The SMTP server allowed a connection but closed the session before verification finished.
UNKNOWN EMAIL
The server says delivery failed and the email does not exist.
ATTEMPT REJECTED
Delivery failed with a rejection-style response.
RELAY ERROR
Delivery failed because of a mail-relaying problem.
ANTISPAM SYSTEM
An antispam system blocked verification progress.
EMAIL DISABLED
The email account is suspended, disabled, or limited and cannot receive messages.
DOMAIN ERROR
The domain mail server or DNS is missing or incorrect, so email is not deliverable.
OK FOR ALL
The server is ready to accept a message for any address on this domain.
DEAD SERVER
The mail server did not respond and appears unavailable.
SYNTAX ERROR
The email address has a syntax error.
UNKNOWN
Delivery failed without a reason that identifies the cause.
EMAIL EXISTS
The email appears to exist, but deliverability information is unavailable.
Catch-all and disposable indicators are shown only where supported by provider evidence or an applicable dataset; a missing flag is not a negative finding.

QUESTIONS.
How are results described?+
Each result includes a plain-language server response so your team can understand what happened.
Are duplicates charged?+
No. Repeated addresses are identified before verification. Duplicate and skipped rows do not consume verification credits.
Does a valid result guarantee delivery?+
No. Mailboxes change, and content, sender reputation, consent, and receiving-system policies still matter.
Does the public demo verify my emails?+
RefreshScan checks CSV structure locally in your browser. Actual mailbox verification runs only through the configured service in your signed-in workspace.
What is the upload limit?+
The current release supports files up to 100 MB and 1,000,000 emails per file.
