Google limits the maximum duration of a script to 6 minutes. That means you can only find between 300 and 500 email addresses at one time, then re-launch it manually.

For the same reason, it isn't possible to select a list of more than 500 domains or company names for the bulk Domain Search on the Google Sheets Add-on. If you select a big list and choose to find many emails per domain, the script could potentially time-out before all the domains have been searched.

For big volumes, we recommend using our Bulk Email Finder and Bulk Domain Search on Hunter's website.

Here's also a dedicated video tutorial for the Bulk Email Finder functionality, and another here for the Bulk Domain Search functionality.
