The Scenario
You're a marketing ops manager. The latest lead gen batch has 500 new contacts in Excel with email addresses in column B. Before they go into Mailchimp, you need to flag disposable or high-risk emails. Three campaigns ago, a batch of throwaway addresses made it through and tanked deliverability for two months.
The campaign send is tomorrow morning.
The bad version:
- Paste emails one by one into a free verifier website that rate-limits at 10 per minute without a paid account.
- Export to a third-party list cleaner, wait 24 hours, import results, reconcile the column mapping.
- Skip hygiene entirely and deal with the bounce rate afterward.
Tomorrow's send is tied to a product launch. A deliverability dip right now would be badly timed.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your Excel workbook and calls Interzoid's email trust scoring API for every row.
For every email in column B (500 rows), call Interzoid to get the trust score and write the numeric score into column C and 'VALID', 'RISKY', or 'INVALID' into column D based on score thresholds.
What You Get
- Column C: numeric trust score (0-99) per email.
- Column D: categorical verdict — VALID, RISKY, or INVALID.
- The Mailchimp import uses only VALID rows, with RISKY rows held for review.
What If the Data Is Not Quite Ready
Some emails in column B have trailing spaces or mixed casing
Trim and lowercase all email addresses in column B before calling Interzoid for trust scores — write cleaned emails to column C, scores to column D, and verdicts to column E.
You want to remove INVALID rows immediately
Delete all rows where column D is 'INVALID' and highlight rows where column D is 'RISKY' in yellow.
Column B has malformed entries (missing @ sign) mixed in
For each row in column B, first check for basic email format. Flag malformed entries as 'MALFORMED' in column D without calling Interzoid. For the rest, call Interzoid for the trust score and write score to column C and verdict to column D.
Full hygiene pass in one shot
For every email in column B: trim whitespace and lowercase, check basic format, call Interzoid for valid-format emails, write scores to column C and verdicts to column D. Delete all rows marked INVALID or MALFORMED and highlight RISKY rows yellow.
One prompt handles formatting, validation, scoring, deletions, and highlighting.
