Quotas for Google Services
Apps Script services impose daily quotas and hard limitations on some features. If you exceed a quota or limitation, your script will throw an exception and terminate execution.
Quotas are set at different levels for users of consumer accounts (like gmail.com), Google Apps free edition (discontinued), or G Suite.
Daily quotas are refreshed at the end of a 24-hour window; the exact time of this refresh, however, varies between users.
The table below lists the daily quotas as of December 2016. You can confirm the current on the Quota Limits tab of the Apps Script Dashboard. The quotas shown below are provided solely to assist you in testing scripts. All quotas are subject to elimination, reduction, or change at any time, without notice.
