Receive an email if spend is getting too high

Get an automatic email when your Google Ads spend is close to last month.

This script helps you keep control of your Google Ads costs when you manage one or more accounts. It compares what you have spent so far this month with what you spent in the previous month, and sends an email alert when your current spend comes close to last month's total.

Setup

1. Set a budget threshold that defines how "close" is close enough. A simple rule of thumb is about twice your average daily budget.
2. Add the email addresses that should receive the alert.
3. Schedule the script in Google Ads to run automatically at your preferred frequency.

When your current month's spend is within that threshold of last month, the script sends an email to your chosen recipients.

What the email includes

• The name of the Google Ads account
• How much you have spent so far this month
• How much you spent in the previous month
• A short explanation that the current month is almost higher than last month

Why this matters

This gives you an early warning that spend is ramping up, so you can check if the increase is intentional (for example due to seasonality or a campaign push), quickly pause or adjust campaigns if needed and avoid unpleasant surprises on your invoice.
