The Scenario
You just purchased a list of 2,000 business email addresses from a data vendor. They came with a guarantee, of course — they always do. You're three days out from importing them into HubSpot, and your deliverability rep has been very clear: one bad batch and the domain takes a reputation hit that takes months to recover from.
The bad version:
- Upload the workbook to Bouncer manually and wait for the toxicity report, then download a second results file on top of the first verification file you already have open
- Try to filter the Excel output for "Toxic" and "Role-Based" categories without overwriting the rows you already marked from a previous pass
- Paste the clean subset into a new worksheet, lose the original row order in the process, and spend 30 minutes reconstructing the full dataset so it can be imported into HubSpot without creating duplicates
The import is in three days. Every hour you spend shuffling CSVs is an hour you're not doing the actual campaign work. And your HubSpot admin is already annoyed about the last import that brought in 200 duplicates.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads your contact data, runs it through Bouncer's toxicity analysis, and writes results back to the workbook — no CSV loop, no manual file merge, no pivot table gymnastics.
Check all emails in column A against Bouncer's toxicity analysis and mark each row Toxic, Role-Based, Disposable, or Clean in column B.
What You Get
- Column B gets a label per row: Toxic, Role-Based, Disposable, or Clean
- The original row order stays intact — no sorting or re-matching needed
- The result is in-workbook, so you can filter column B directly in Excel without opening a second file
- Clean rows are ready to highlight, copy, or export as-is for HubSpot import
What If the Data Is Not Quite Ready
The emails are spread across multiple columns (first, last, company, email in column D)
Run a Bouncer toxicity scan on the emails in column D, write the result label to column E, and sort the worksheet so all non-Clean rows appear at the top.
You want to keep the clean contacts in a separate worksheet
Check all emails in column A against Bouncer's toxicity API, mark results in column B, then copy only the rows where column B is Clean into a new worksheet called Safe Import.
The workbook includes obvious formatting issues alongside the toxicity concerns
First remove any row in column A where the email has no @ symbol or ends in a number-only TLD, then run Bouncer toxicity on the remaining emails, write statuses to column B, and give me a count breakdown by category.
Full pre-import cleanup in one prompt
For this contact list: strip rows with malformed emails, deduplicate by column A keeping the latest row, run Bouncer toxicity analysis on all remaining addresses, write the result to column B, remove any row marked Toxic or Disposable, and tell me the final row count and how many contacts were removed in each category.
One prompt does what would otherwise be four separate operations across two files.
Try It
