The Scenario
You are a developer advocate at a SaaS company. The new onboarding email sequence launches in 48 hours and you need 800 subscribers imported into the Mailtrap contact list before the first drip fires.
The list is in a Google Sheet: emails in column A, first names in column B, last names in column C. Simple enough. But you have never done a bulk import into Mailtrap before and the API docs are not exactly light reading.
The bad version of the next two hours:
- You read the Mailtrap API docs to find the bulk contact import endpoint
- You write a script, get the auth wrong, fix it, get the pagination wrong
- You run the import, hit a rate limit, back off, rerun
- You try to check how many contacts were actually created and the dashboard number does not match your sheet count
- You are still debugging at midnight and the sequence fires with a partial list.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that reads the data and handles the Mailtrap API call for you, so you do not have to write a single line of import code.
Open the SheetXAI sidebar and type:
Take all emails in column A, first names in column B, and last names in column C and bulk-import them into Mailtrap contact list ID [list_id]. Write the import job status and the number of contacts successfully created into cell D1 once complete.
SheetXAI reads the sheet, calls the Mailtrap bulk import endpoint with the right payload, waits for the job to finish, and writes the result back to D1. The sequence launches with the full list.
What You Get
A confirmed import result written directly into the sheet:
- Contact count — how many were created successfully
- Status — confirmation the job completed without errors
- Error flag — if any rows were rejected, SheetXAI notes the count and reason
You do not have to cross-check the Mailtrap dashboard against the sheet yourself. The status lands in D1 and you know immediately whether to move on or investigate a rejection.
Need to import into a second list? Give SheetXAI the second list ID and ask it to repeat the import from the same column range.
What If the Data Is Not Quite Ready
Real subscriber lists almost never arrive clean. SheetXAI handles the cleanup and the import in the same prompt.
When email addresses have inconsistent formatting
Some rows have trailing spaces, some have uppercase domains, some have both.
Normalize all emails in column A to lowercase and strip whitespace before importing them into Mailtrap contact list ID [list_id]. Write the count of addresses that were modified into cell E1 and the import status into D1.
When first and last names are in a single column
The export you received has full names in column B instead of split first and last name columns.
Split the full names in column B into first name and last name using the first space as the delimiter. Then import all rows into Mailtrap contact list ID [list_id] with email from column A, first name and last name from the split values. Write import status into D1.
When you only want to import subscribers who opted in this month
The sheet has 18 months of subscribers but you only want this month's cohort.
Filter to rows where the opt-in date in column D falls within the current calendar month. Import only those rows into Mailtrap contact list ID [list_id] with email from column A and names from columns B and C. Write the count of imported contacts into D1.
When the sheet has duplicates and partial data you need to clean first
You merged two export files and now have duplicate emails, blank names, and a handful of clearly invalid addresses.
Deduplicate rows in this sheet by email address in column A, keeping the row with the more recent opt-in date in column D. Remove any rows where column A is blank or does not contain an "@" symbol. For any row where column B is blank, use "Subscriber" as the first name. Then import all remaining rows into Mailtrap contact list ID [list_id] and write the final import count into D1.
The pattern: instead of cleaning the sheet first and then figuring out the API separately, you describe both jobs in one prompt and SheetXAI handles the sequence.
Try It
Get the 7-day free trial of SheetXAI and open any sheet with subscriber data, then ask it to push the list into Mailtrap. The Mailtrap integration is included in every SheetXAI plan. See also how to audit suppressed addresses before your next send or the Mailtrap in Google Sheets overview.
