Your first $5 of validations are on us, valid for 30 days. No card required.

Why ScoreMachine
A mail server accepts your message. Whether anybody opens the message is a different question, and you find out after the send.
01
Protect your sender reputation before the send
A hard bounce tells the mailbox provider your list is stale. deliverability.status returns false before anything is sent, and last_seen dates the rest.
02
Find out when the mailbox was last active
A mail server keeps accepting mail for a mailbox nobody has opened. last_seen returns when the mailbox last showed activity, from digital footprint signals.
03
See the host behind the domain and match ESPs
A vanity domain says nothing about what runs the mailbox. mx_record returns the host that actually receives the mail.
04
Check for free emails
A sequence written for a named buyer lands in a shared company inbox. sub_status classifies the mailbox behind a valid address.
05
Clean both halves of a contact record on one account
A contact row carries an address and a number, bought from two vendors. score.email.validation and score.phone.scoring run on one token, in one request envelope.
06
See what has been recorded against an address
A row arrives with no history. An old import and a live signup look the same. score.email.tags returns which of 21 interest categories an address has turned up in, and when.
One request returns the verdict, the technical evidence and the last-seen date.
Methods
Check incoming addresses 2,000 to 10,000 at a time with sequential methods, or run a whole file through the batch methods.
Sequential methods
Batch methods
Web UI
Upload a CSV or XLSX in the workspace, up to 5 MB and 200,000 rows. Map columns, pick methods, see the price, and export the scored file.
API
JSON-RPC 2.0. Send 2,000 to 10,000 addresses per request to the sequential methods, or run a whole file as a batch job, up to 10 concurrent jobs.
Developers →White-glove onboarding
Our team sets up the first runs with you: file mapping, method choice and the export format your systems import.
ScoreMachine vs standard email validation
Standard email validation checks the syntax, resolves the domain and its MX records, then opens an SMTP conversation with the receiving mail server. The verdict is whatever that server’s response code says.
Standard validation answers whether a mail server will take the message. ScoreMachine returns that answer and the date the mailbox was last active.

The token arrives in the Token response header, not in the body. The body carries the user record. Tokens last 24 hours; call auth.login again when one expires.
A successful call here confirms the token is live and the account is funded. Balances are floating-point USD. For batch jobs, audiences.score.price quotes the run before it starts.
emails takes 2,000 to 10,000 addresses per request. deliverability.status is the verdict; last_seen is the last-seen date.
Errors come back in the standard JSON-RPC envelope with code, message and optional data. Retry transient failures with backoff. Full method reference, error list and troubleshooting at doc.scoremachine.ai.

Email validation confirms the address format, the domain, and whether the mail server accepts mail. ScoreMachine returns the mail host behind the domain and the mailbox classification. last_seen returns when the mailbox was last active.
Last-seen resolves for more than half of addresses globally, Gmail included.
A syntax checker confirms an address could exist. ScoreMachine resolves the domain and returns mx_record, the host that receives the mail. sub_status classifies the mailbox. last_seen returns when the mailbox was last active.
Sending to addresses that no longer accept mail is the largest controllable cause of hard bounces. Validating before a send removes those addresses from the file. What you send after that is your own.
Yes. CSV or XLSX upload takes up to 5 MB and 200,000 rows. The API takes 2,000 to 10,000 addresses per request. The Web UI tab of the tour above runs a file end to end, from upload to export.
Every field the page shows describes the address or the mailbox. Format, domain, MX record, mailbox classification and the last-seen date. Tags come back named and dated, exactly as recorded.
We delete query data within 24 hours. Operational logs and backups are kept for 30 days, then deleted.
Yes. Phone and email run on one account, one token and one request envelope. See Phone Validation.
