The Scenario
You're an email deliverability consultant and you have a Google Sheet with 200 client sender domains in column A. Three clients are seeing inbox placement drop, and you suspect domain reputation issues. Before you walk into a call and tell them their sender domain is on a blacklist, you need data.
The standard move is to run each domain through a reputation checker manually. But 200 domains means 200 manual lookups, and you have a client call in two hours.
The bad version:
- Open a DNS blocklist check tool, paste domain one at a time, record the blacklist count and affected lists in a side document
- Paste results back into the sheet row by row, matching by domain string
- Realize at row 80 that the tool resets your results view after a session timeout and you've lost your place
You charge by the hour, and this is not billable work. It's pre-work that was supposed to take 20 minutes.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. Through its built-in Neutrino integration, it runs a host reputation check on every domain in column A and writes the blacklist hit count and affected list names into the columns you specify.
For each domain in column A, run a Neutrino host reputation check and write the blacklist count and any flagged lists into columns B and C.
What You Get
- Column B: the number of DNS blocklists the domain appears on
- Column C: the names of the specific lists where the domain is flagged
- All 200 domains processed in one pass — ready to sort by column B and identify the highest-risk senders before the call
What If the Data Is Not Quite Ready
You want to flag any domain with more than 2 blacklist hits as a priority case
Check all 200 domains in column A against Neutrino host reputation. Write the blacklist count in column B and the flagged lists in column C. Mark any domain with more than 2 hits as FLAGGED in column D and highlight those rows in red.
Some domains in column A include a subdomain prefix that should be stripped before checking
For each domain in column A, strip any subdomain prefix (anything before the first registered domain) and write the cleaned domain in column B. Then run Neutrino host reputation on the cleaned domain and write the blacklist count in column C and flagged lists in column D.
You want to cross-check against each client's name in column B and produce a per-client summary
Run Neutrino host reputation on all domains in column A. Write the blacklist count in column C and flagged lists in column D. Then produce a summary table below the data showing, for each unique client name in column B, the count of clean domains and the count of flagged domains.
Full deliverability audit in one shot
Strip subdomain prefixes from all values in column A, run Neutrino host reputation on each cleaned domain, write the blacklist count in column B and flagged lists in column C, flag any domain with more than 2 hits as FLAGGED in column D, highlight FLAGGED rows red, and produce a sorted summary at the bottom ranking clients by their highest blacklist count.
