Is there a limit to the number of emails I can send?

Yes, you can send up to 2,000 messages per day. Outgoing messages must also conform to the limits of 10,000 total recipients per day (including the To, CC, and BCC fields) and 100 recipients per message. A large number of recipients can best be managed by creating a Google Group (mailing list) that contains those recipients and sending to its single address. For more information on limits, see:
