Email Verifier

Check whether an email address is deliverable. Clean a list before a campaign: know which addresses are deliverable, risky or invalid.

Credits: 1 verification credit (unknown and disposable results are free). Lookups that find nothing cost nothing. See Pricing and limits.

Inputs and options

Input: email (Email address)

Try one value

Code
CALL TOMBA.core.email_verifier('jane.doe@acme.com');

The call returns the result as a VARIANT (example values, shortened):

Code
{
    "status": "found",
    "credits": 1,
    "results": [
        {
            "EMAIL": "jane.doe@acme.com",
            "STATUS": "valid",
            "RESULT": "deliverable",
            "SCORE": 99,
            "ACCEPT_ALL": false
        }
    ]
}

status is found, not_found, invalid or error; results holds the output columns and data the complete Tomba record.

Run it over a table

Create a small table to try it (or use one of yours, after granting the app access):

Code
CREATE OR REPLACE TABLE my_db.public.contacts (EMAIL STRING);
INSERT INTO my_db.public.contacts VALUES
    ('jane.doe@acme.com'),
    ('info@globex.com');
GRANT USAGE ON DATABASE my_db TO APPLICATION TOMBA;
GRANT USAGE ON SCHEMA my_db.public TO APPLICATION TOMBA;
GRANT SELECT ON TABLE my_db.public.contacts TO APPLICATION TOMBA;

Run the tool, then read the results:

Code
CALL TOMBA.core.verify_emails('MY_DB.PUBLIC.CONTACTS', 'EMAIL', 'CONTACTS_EMAIL_VERIFIER', 100);

SELECT INPUT_EMAIL, STATUS, RESULT, SCORE, ACCEPT_ALL, DISPOSABLE, WEBMAIL
  FROM TOMBA.results.CONTACTS_EMAIL_VERIFIER
 WHERE lookup_status = 'found';

Signature: verify_emails(input_table STRING, email_column STRING, output_table STRING, max_rows INT DEFAULT 100000)

Output columns

Each row has your INPUT_<name> columns, the tool's columns, and the common columns (LOOKUP_STATUS, CREDITS, DATA, …). Every column, with its type and values: Output columns.

Tips

• STATUS and RESULT hold the verifier's status and result in lowercase. What each value means: Email verifier response.
• Send only valid addresses, and treat accept_all as risky: the server accepts every address, so it can't be confirmed.
