Google Sheets Add-on Limits
Google Apps Script enforces a maximum execution time of 6 minutes per script run.

🔹 What this means in practice:
You can search for 300 to 500 email addresses at a time before needing to manually restart the process.
You cannot select more than 500 domains for Bulk Domain Search in the Google Sheets Add-on.
Even under 500 domains, timeouts may occur especially when requesting more than 10 emails per domain.
Need to process larger volumes?
For better performance and no timeouts, we recommend using the Bulk Email Finder or Bulk Domain Search.
