The Scenario
You are a sales rep. Your manager just handed you a list of 80 target accounts for Q3 in a Google Sheet. Column A is email, the rest of the row has the usual firmographic data.
There is a Mixmax contact group called "Q3 Enterprise" that the whole team uses to coordinate outreach. Every contact on your list needs to be in that group before the outreach wave begins on Thursday.
The bad version of this Tuesday afternoon:
- You open Mixmax and navigate to the contact group
- You look for a way to add contacts in bulk
- The UI only lets you add one at a time from a search field
- You start searching for each email and clicking "Add"
- By contact 20 you are moving slowly enough that someone else on the team has started the wave early without your contacts in the group
- Thursday arrives with 40 of your 80 contacts missing from the group.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that reads the data and calls Mixmax directly, so you do not have to use a search field 80 times.
Open the SheetXAI sidebar and type:
Add every email address in column A of this sheet to the Mixmax contact group named "Q3 Enterprise." Write "Added" or the error into column B for each row.
SheetXAI reads column A, calls Mixmax's contact group API for each email, and writes the result into column B. All 80 contacts, one prompt.
What You Get
80 contacts added to the "Q3 Enterprise" group, with a status column showing what happened per row:
- "Added" — the contact was found in Mixmax and added to the group
- Error message — for any email not found as a Mixmax contact, so you know which rows need to be created first
The error column is the thing the UI cannot give you. When you add contacts one at a time, you have no record of which ones failed. The status column in the sheet is your audit trail.
Want to create any missing contacts first and then add them to the group in the same prompt? Tell SheetXAI to do both. It adjusts.
What If the Data Is Not Quite Ready
Target account lists from sales planning meetings are rarely field-perfect. SheetXAI handles the edge cases in the same prompt.
When some emails in column A are not yet Mixmax contacts
The list has 80 emails but only 60 of them exist in Mixmax as contacts. You want to create the missing ones before adding them to the group.
For each email in column A, first check if a Mixmax contact exists. If not, create the contact using column A as email and column B as company. Then add the contact to the Mixmax contact group named "Q3 Enterprise." Write the result into column C.
When the sheet has duplicate emails
The target account list was assembled from two sources and has some repeating emails.
Deduplicate column A by email address, keeping the first occurrence. Then add each unique email to the Mixmax contact group named "Q3 Enterprise." Write the result into column B.
When you are adding contacts to multiple groups
The 80 contacts belong to both "Q3 Enterprise" and "Tier 1 Accounts," a second group your manager wants populated.
Add every email address in column A to both the Mixmax contact group "Q3 Enterprise" and the group "Tier 1 Accounts." Write the combined result into column B.
When you want to create, group-add, and report in one shot
Your contacts do not exist in Mixmax yet, you need to create them, add them to the group, and write a summary of what happened, all before Thursday.
For each row in this sheet, create a Mixmax contact using column A as email, column B as first name, column C as last name, and column D as company. Then add each contact to the Mixmax contact group "Q3 Enterprise." Write "Created + Added," "Created only," or the error into column E. At the bottom of the sheet, write a count of how many contacts were successfully added to the group.
The pattern: describe the full operation in one prompt and SheetXAI handles the row-level conditional logic.
