The Scenario
You are an email developer. It is Thursday afternoon. Eight new transactional email drafts are sitting in a Google Sheet, one raw email source per row in column A. They are ready for spam scoring before you deploy them to production on Friday.
Your deliverability team has a rule: anything that scores above 5.0 on the SpamAssassin scale does not go to production without a rewrite. You need scores, rule counts, and the name of the highest-risk rule for each draft, so the team can triage quickly.
The slow version:
- Open a spam check tool, paste draft 1 in, wait, copy the score, paste it into the sheet
- Repeat eight times
- Manually note the highest-risk rule for each
- Build a column that flags the high-risk ones
- Realize draft 4 was pasted incorrectly, redo it
- Forty minutes of copy-paste that adds zero creative value.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that submits each draft to Postmark's spam check API and writes the scoring results back into the sheet, with a flag column for high-risk drafts.
Open the SheetXAI sidebar and type:
For each raw email source in column A of the 'Spam Tests' sheet, call the Postmark spam check API and write the spam score into column B, the rule count into column C, and the highest-risk rule name into column D. In column E, write 'HIGH RISK' for any row where the score exceeds 5.0, otherwise leave blank.
SheetXAI submits each raw email source to Postmark's spam check endpoint and writes the four output columns. The HIGH RISK flag in column E tells the team exactly which drafts need attention before tomorrow.
What You Get
A spam scoring table with per-draft results:
- Column B — spam score (lower is better)
- Column C — total rule count triggered
- Column D — the highest-risk rule name from SpamAssassin
- Column E — 'HIGH RISK' for scores above 5.0
The deliverability team can sort column E and see all flagged drafts immediately. No dashboard navigation, no copy-paste, no manual flag column.
Want to add a "Needs rewrite" status column based on the team's triage? Tell SheetXAI to write "Needs rewrite" in column F for any row where column E is "HIGH RISK" and column C shows more than 3 rules triggered.
What If the Data Is Not Quite Ready
Email draft sheets are messier than they look.
When some rows are empty because drafts are still being written
Three of the eight slots in column A are blank — those templates are not ready yet.
For each non-blank row in column A of the 'Spam Tests' sheet, call the Postmark spam check API and write score, rule count, and top rule name into columns B, C, and D. Skip blank rows.
When the raw email sources have Windows-style line endings that cause parsing issues
Copy-pasted email source from Outlook sometimes includes \r\n line endings that confuse the spam check API.
Normalize line endings in column A of the 'Spam Tests' sheet to Unix-style before submitting each row to the Postmark spam check API. Write score into column B, rule count into column C, and top rule name into column D.
When the team wants the rules sorted by risk score, not by name
The deliverability lead wants to see the worst rule first, not alphabetically.
For each row in column A of the 'Spam Tests' sheet, call the Postmark spam check API. Write the total score into column B and list the top 3 rules sorted by their individual scores descending into columns C, D, and E. Flag rows with total score above 5.0 as 'HIGH RISK' in column F.
When you need scoring, flagging, triage notes, and a summary in one shot
The deliverability lead wants a single view to bring to the production review meeting.
For each raw email source in column A of the 'Spam Tests' sheet, call the Postmark spam check API. Write spam score into column B, rule count into column C, top rule name into column D. Flag 'HIGH RISK' in column E for scores above 5.0. In column F, write a one-sentence triage note for each HIGH RISK row explaining the most likely cause based on the top rule name. Add a summary row at the bottom showing average score, total HIGH RISK count, and the single most common rule across all drafts.
The pattern: instead of scoring drafts and then writing triage notes separately, you ask for the full deliverability review in one prompt.
