Google's Gmail was the first free online email service to offer storage capacity of more than 1GB and maximum message sizes of up to 25MB -- making it popular with people who send and receive large amounts of email. To reduce the risk of spammers using Gmail to send junk messages, Google imposes a limit of 500 recipients per day for outgoing email messages. However, there are workarounds you can use to send your messages to more recipients.
Create a second Gmail account to send to additional recipients. To create a new Gmail account, sign out of Gmail, then click "Sign In." On the Gmail front page, click "Create an Account" and follow the directions. When you have reached the maximum number of daily recipients in one Gmail account, sign out of that account and sign into the second account. Google does not limit the number of Gmail accounts you can create.
Purchase Google Apps for Business. Each Google Apps for Business email account can send email to 2,000 recipients per day. To learn more about Google Apps for Business or to sign up, go to google.com/apps/business.
Check to see whether your school offers Google Apps for Education. Each Google Apps for Education email account can send email to 2,000 recipients per day.
Create a Google Group to send frequent messages to a large group of people. To set up a Google Group, go to groups.google.com and click "Create." While there is no membership limit in a Google Group, Google limits posts on a daily basis to prevent spam.
Use an email marketing service such as Aweber or MailChimp to send bulk messages. These services enable you to maintain a mailing list and offer assistance to prevent your messages from being flagged as spam, which is especially important if you send frequent messages to a large number of recipients.
Sending repeated email messages to a large number of recipients can result in recipients flagging your messages as spam. Always make sure your recipients have granted permission to be included on any mailing list.
If you use a POP or IMAP client, such as Microsoft Outlook or Apple Mail, you may send a message to only 100 people at a time.
