The Scenario
You're an email marketing manager. Your 15,000-row subscriber list has grown across three acquisition channels over the past year. Before the product announcement campaign goes out, you need a hygiene pass: which addresses are valid, which are risky, which domain types are you sending to.
Last quarter's campaign hit 4.2% bounces. The threshold for a suppression review is 3%.
The bad version:
- Run the list through a bulk verifier with a 5,000-row upload limit — three separate uploads, three result files to reconcile back into your Excel workbook.
- Pay for a premium hygiene service, wait two business days, receive a file you still have to map back to your column structure.
- Send without hygiene and document that the timeline didn't allow for it.
The campaign is end of week. The bounce rate conversation with leadership would be worse than the delay.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your Excel workbook and calls Interzoid's email info API for every subscriber — validation status, domain type, and geographic region written back directly.
For every email in column A, call Interzoid's email info tool and write the validation status, domain type, and detected country to columns B, C, and D.
What You Get
- Column B: validation status — VALID, RISKY, INVALID.
- Column C: domain type — business, free, educational, disposable.
- Column D: detected country associated with the email domain.
- A workbook ready for suppression filtering before the send.
What If the Data Is Not Quite Ready
Column A has duplicate emails from the three acquisition channels
Deduplicate column A (keep first occurrence), then call Interzoid's email info tool for each unique email and write validation status, domain type, and country to columns B, C, and D.
You want trust score and deliverability verdict as additional fields
Use Interzoid to enrich all emails in column B with trust score, deliverability verdict, and detected region — write results to columns C, D, and E, then filter to remove rows flagged INVALID.
You don't want to delete rows — just add a filter view
Filter out rows where column B is blank before enriching. For remaining rows, call Interzoid email info and write status, domain type, and country to columns C, D, and E. Add a filter view showing non-INVALID records rather than deleting rows.
Full hygiene + enrichment in one pass
Deduplicate column A, skip blanks, call Interzoid email info for each unique non-blank email. Write status to column B, domain type to column C, country to column D, trust score to column E. Create a summary worksheet showing counts by status and domain type.
The campaign goes out with a clean list and a summary to share with your director.
