This Flowbot procedure consists of two steps in total!
Setting Triggers in Google Sheets
First, prepare a Google Sheet to be integrated with Gmail and pre-enter the items.

This time, I created a Sales List as shown in the image.
Once the Google Sheet is created, proceed to the next step.
↓
Click on "My Projects" on the left side of the screen and select "Send an email with Gmail when a row is updated in Google Sheets (Copy)"!
Click on Edit at the top right.
↓
Click on the Google Sheets icon "When a row is updated".
Since the necessary items are pre-entered using the template, just make sure the account information is correct.
Click Next.
↓

First, enter the ID of the spreadsheet.
Click inside the box to display a list as shown in the image, and select the Google Sheet you want to integrate with Gmail.
The Sheet ID below is the tab name, so click inside the box and specify the tab.

Other required items depend on the prepared Google Sheet, so enter them according to the contents of the Google Sheet.
This time, I chose "Date" for the column to detect updates.
By updating the date, emails will be sent via Gmail!
For columns with unique values, choose something that doesn't overlap with others, like phone numbers.
↓
Once you've entered everything, click the Test button at the bottom of the screen. If "Test Successful" is displayed in blue, you're good to go!
Don't forget to click the Save button. Next, we'll move on to Gmail settings!
Gmail Settings
Click on the Gmail icon "Send Email".
Again, since the necessary items are pre-entered using the template, just make sure the account information is correct.
Scroll down the screen as it is
↓

Set the contents of the email. First, decide the recipient.
You can also set CC and the sender's name, so enter them if necessary.
↓
The next setting is the last one! Decide the content to be notified by Gmail.
Click inside the box, and when you click on the Google Sheets icon "When a row is updated", the contents of the Google Sheet you test-sent earlier will be displayed.
Click on the content you want to notify and add it!

I tried it like the image this time!
Adding colons ":" and such can make it easier to read. Please try to imitate it!
Press Test, and if "Test Successful" is displayed in blue, save it. If an email has arrived from Gmail to the specified email, it's OK!
This concludes the integration of Google Sheets and Gmail. Well done!
Yoom has many other Flowbot templates available, so please take a look.
