The Scenario
You are a CRM admin. The re-engagement campaign goes out next Monday. Sitting in an Excel workbook:15,000 customer email addresses that have not been emailed in 18 months. Before any of them go into SendGrid's send queue, every one needs to be checked against the bounce list, block list, invalid address list, and spam report list.
Send to a bounce and your deliverability score takes a hit. Send to a spam report and you risk account suspension.
The slow version:
- Export each suppression list from SendGrid as a separate CSV
- Import all four CSVs into Excel as separate tabs
- Write VLOOKUP formulas across four tabs to cross-reference column A
- Merge the results into a status column
- Go back into SendGrid and manually delete the actionable suppressions
- Two full days of formula work. The campaign is late.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that calls the SendGrid suppression APIs, classifies every email in your workbook, and cleans up the records in SendGrid, all in one operation.
Open the SheetXAI sidebar and type:
For each email in column A of this workbook, check SendGrid and write in column B whether it's a 'bounce', 'block', 'invalid', 'spam_report', or 'clean'. Once all rows are classified, delete every 'bounce' and 'invalid' entry from SendGrid's suppression list so I can re-attempt delivery on those addresses.
SheetXAI works through all 15,000 rows, writes a classification into column B, and removes the actionable suppression records from SendGrid.
What You Get
A classified workbook with five possible statuses in column B:
- "clean" — safe to send
- "bounce" — previously bounced; removed from SendGrid after the run
- "block" — blocked by the receiving server; flagged for review
- "invalid" — malformed or non-existent address; removed from SendGrid
- "spam_report" — recipient marked you as spam; do not contact
The bounce and invalid records are removed from SendGrid's suppression list after the run, so future sends to those addresses will be attempted rather than silently skipped.
What If the Data Is Not Quite Ready
When email addresses have trailing spaces or inconsistent capitalization
Trim whitespace from every email in column A and convert them all to lowercase. Then check each cleaned email against SendGrid's bounce, block, invalid, and spam_report lists and write the result in column B.
When you only want to remove suppressions for contacts who re-confirmed consent
Column C has a "reconfirmed_consent" flag.
For each email in column A, check SendGrid's suppression lists and write the result in column B. Then, for every row where column C says 'reconfirmed_consent' and column B says 'bounce' or 'invalid', remove that email from SendGrid's global suppression list and write 'removed' or 'not_found' in column D.
When you want to route spam reports to a different team
Check all emails in column A against SendGrid suppression lists. Write the category in column B. For any row where column B is 'spam_report', write 'FLAG — route to CS' in column C. Leave column C blank for all other categories.
When the workbook has two email columns that both need scrubbing
For each row, check both the email in column A and the email in column D against SendGrid's suppression lists. Write the status for column A's email in column B and the status for column D's email in column E. If both emails are suppressed, write 'BOTH SUPPRESSED' in column F.
The pattern: the suppression check and the cleanup are one operation. You do not import four CSVs or write VLOOKUP formulas.
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with a contact list, then ask it to check every email against SendGrid's suppression lists. The SendGrid integration is included in every SheetXAI plan. For related workflows, see how to bulk-add emails to SendGrid suppression groups from Excel or the SendGrid in Excel overview.
