You can usually send up to 500 emails at once with a regular (free) Gmail account, as long as the total number of recipients in that one message does not exceed 500 addresses.

Below is a clear breakdown so you don’t get blocked or throttled.

Quick Scoop

  • Personal @gmail.com:
    • Up to 500 recipients per single email.
* Daily cap is also about 500 emails/recipients in 24 hours, so one blast to 500 people can use your full quota.
  • Google Workspace (paid work/school accounts):
    • Can send to more recipients per message, commonly up to around 2,000 recipients total in one email, with a lower cap for external addresses.
* Higher daily limits: roughly 2,000 messages per day, and up to around 10,000 total recipients per day depending on configuration.
  • If you go over:
    • Google can temporarily block sending for about 24 hours if you exceed limits or look spammy.

Important nuances

  • “At once” means total recipients in the To, Cc, and Bcc fields added together for that one send.
  • Hitting the full 500 in a single send from a personal account is allowed but can increase the chance of spam filtering or temporary throttling, especially if done often.
  • For large campaigns (thousands of emails), most people use tools or add‑ons that drip‑send over time and stay within Gmail’s limits.

Tiny example

If you have a normal @gmail.com address and a list of 800 people:

  1. You can send 1 email to 500 recipients (using Bcc is usually better for privacy).
  1. You cannot immediately send another 300 to new recipients the same day without risking hitting the 500‑per‑day cap.
  1. With a Google Workspace account configured with higher limits, you might be able to send to all 800 in one or two messages, depending on your admin’s settings.

Bottom line:

  • Regular Gmail: safely think “up to 500 recipients in a single email, and about 500 total per 24 hours.”
  • Workspace Gmail: limits are higher (up to around 2,000 recipients in one email), but still capped and admin‑controlled.
