The Problem With Getting Workbook Data In and Out of Bouncer
You have an Excel workbook full of email addresses — an imported contact list, a CSV of form submissions, a purchased lead file — and you need every address checked before the campaign goes live. Bouncer tells you whether a given address will bounce, whether it's a disposable, whether the domain is a catch-all. But the gap between your workbook and Bouncer's API is where the afternoon disappears. The standard flow is to save the workbook as a CSV, upload it to Bouncer, wait, download the result file, and then manually match statuses back to your original rows.
Below are the four common ways teams handle this. Only the last one scales.
Method 1: CSV Export and Manual Rejoin
The default in Excel workflows. You save the workbook as a CSV, upload to Bouncer's batch interface, wait for the job to finish, download the output, and then open both files to match results back to your original data.
For a 200-row list, this is a half-hour job. For a 5,000-row list where the output columns don't quite align with your original headers, you're into a merge-by-email-address situation that takes longer than the verification itself. Every campaign cycle, you start the same sequence from scratch — save, upload, wait, download, rejoin, clean.
Method 2: Power Automate
Power Automate has Bouncer connector options. You can wire up a trigger on a new Excel row, call Bouncer's single-email endpoint, and write the status back to the workbook.
Quick pause — are you comfortable with Power Automate flows? Connection references? Trigger conditions on Excel Online? Bouncer's API schema and how to pull a field from its response body? If any of that sounds like territory you don't usually operate in, jump ahead to Method 3 or 4.
For those who stayed: the flow works. You authenticate, configure the trigger, map the email field, extract the status from the JSON response, write it to the right column.
The hard ceiling is that it fires on one row at a time.
Running a 2,000-address list through Power Automate means 2,000 individual API calls — and if your Microsoft 365 plan doesn't include high-volume flow runs, you'll hit rate limits before you hit row 300.
You probably just need to know which addresses on that list are deliverable. You probably have no idea what a connection reference is or how to handle Bouncer's response schema in Power Automate. So this goes to IT or whoever in the company manages automations, and now the campaign send date is slipping while you wait on a ticket.
Method 3: The Previous Generation — Connector Add-Ons
Until recently, the best option for repeatable workbook ↔ Bouncer workflows was a category of add-ins that let you configure column mappings and run saved templates against your data. You'd point the tool at your email column, define the output fields, save the configuration, and run it.
That was a meaningful improvement over the CSV cycle. Configs were reusable, output was predictable, and you didn't have to manually rejoin two files every run.
But you were still the one defining every field mapping, every output column, every condition for which rows to include. The tool moved the data, but the decisions were still on you. When a column got renamed or a new field appeared in Bouncer's response, the saved config broke until someone fixed it.
This is the previous generation. It worked, but it asked a lot of the operator.
The Easy Way: Using SheetXAI in Excel
There is a different way entirely. SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands your data, and through its built-in Bouncer integration it can submit your email list, retrieve results, and write them back — without CSV exports, config files, or manual rejoins. You just ask.
Example 1: Batch verify a contact list and mark bad rows
Verify the emails in column A with Bouncer's batch API and write the result status (valid, invalid, catch-all, unknown) into column B — highlight any row where the result is invalid or disposable in red.
SheetXAI submits the list, polls the batch job, and writes each status back to the corresponding row. Invalid and disposable rows get a red fill so they're easy to find at a glance.
Example 2: Filter the list down to clean contacts only
Run Bouncer verification on this workbook's email list, remove any row where the result is invalid or disposable, and paste the filtered rows into a new worksheet called Safe List.
The pattern: instead of verifying first and filtering second in two separate steps, you ask for both at once. SheetXAI handles the conditional logic and the sheet write in a single operation.
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with an email list, then ask it to verify against Bouncer. The Bouncer integration is included in every SheetXAI plan.
