The Scenario
You are a membership site owner. You have 600 subscribers in your Kit account. You also have a Google Sheet from your billing system — column A is subscriber email, column B is their membership tier: Free, Pro, or Enterprise.
Your billing system just updated. Tiers shifted. Forty people upgraded, twenty downgraded, fifteen are new. You need every one of those 600 Kit subscribers to carry the right tag before you trigger the monthly members-only email.
The bad version of this Tuesday:
- You export your Kit subscriber list as CSV
- You open it in Sheets alongside the billing export
- You do a VLOOKUP to match tiers to emails
- You realize Kit's CSV import does not apply tags to existing subscribers — it only creates new ones
- You look up the Kit API docs
- You write a script, or find someone who can
- Three hours later the tags are 80% right and you are out of time
- The email goes out to the wrong segments.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your sheet and calls Kit's API to tag each subscriber directly, no scripting, no export-and-reimport.
Open the SheetXAI sidebar and type:
For each row in the Members sheet, find the Kit subscriber by the email in column A and apply the tag from column B. If the tag does not exist in Kit, create it first. Log "tagged," "subscriber not found," or "error" in column C for each row.
SheetXAI goes through all 600 rows, looks up each subscriber in Kit, applies the tier tag, creates the tag if it is missing, and logs the result. Six hundred rows done before you finish your coffee.
What You Get
Every subscriber tagged with their current membership tier, with a status log you can filter:
- Free, Pro, Enterprise tags applied per subscriber from column B
- Tag auto-creation — any tier label that does not yet exist in Kit gets created before it is applied
- Status in column C — "tagged," "subscriber not found," or "error" so you know which rows need follow-up
The "subscriber not found" rows matter. If someone in your billing system is not in Kit yet, you know immediately instead of finding out when your segment send comes back short.
If a subscriber should only have one tier tag at a time, tell SheetXAI to remove the previous tier tag before applying the new one. It handles the lookup and the cleanup in the same pass.
What If the Data Is Not Quite Ready
Billing exports are rarely aligned perfectly with what Kit needs. SheetXAI handles the discrepancies inline.
When tier labels in the sheet do not match Kit tag names
Your billing system exports "free_plan," "pro_plan," and "enterprise_plan." Your Kit tags are "Free," "Pro," and "Enterprise."
Map the tier values in column B before tagging: treat "free_plan" as "Free," "pro_plan" as "Pro," and "enterprise_plan" as "Enterprise." Then tag each Kit subscriber in column A with the mapped tier value.
When some rows have the same email twice
Your billing export has duplicates — the same subscriber appears once as an upgrade and once with their old tier.
Deduplicate this sheet by email in column A, keeping the row with the higher tier (Enterprise > Pro > Free). Then tag each Kit subscriber with the resulting tier from column B.
When you need to remove old tier tags before applying new ones
Subscribers have accumulated multiple tier tags over time. You want each one to carry only their current tier.
For each subscriber in column A, remove any existing tier tags (Free, Pro, Enterprise) from their Kit record first, then apply the current tag from column B. Log the result in column C.
When you also need to add them to a tier-specific sequence
Same tagging operation, but Pro and Enterprise subscribers should also be added to the Pro Onboarding sequence.
For each row, tag the Kit subscriber in column A with their tier from column B. For any subscriber whose tier is Pro or Enterprise, also subscribe them to the Kit sequence named Pro Onboarding. Log "tagged," "tagged + sequence," or "error" in column C.
The pattern: the tagging and the conditional logic happen in the same prompt. You do not need a separate step for each operation.
Try It
Get the 7-day free trial of SheetXAI and open any sheet where a column tells you what tag a subscriber should have, then ask SheetXAI to apply them. The Kit integration is included in every SheetXAI plan. For the related cleanup operation, see how to bulk remove Kit tags from a sheet or the Kit in Google Sheets overview.
