Explanation of hourly or daily email sending limits for individual Yahoo! Mail accounts. Also provides alternative suggestion utilizing Yahoo! Groups.

To help prevent spam and potential abuse, Yahoo! has established sending limits for outbound messages for all Yahoo! accounts.

Understanding message limits:

• Because of our antispam policies, we cannot disclose the specific limits on the number of emails you can send, or the number of contacts you can email at once.
• For this reason, if you are notified that you have reached the hourly or daily sending limit, please allow the appropriate amount of time to pass before trying to send again.
• We hope you understand our need to protect the integrity of our products for all Yahoo! customers when emailing actions trigger our spam filters, or when there are too many recipients in one email.

Alternative suggestion for sending higher volumes of email:

• Try Yahoo! Groups: Try using Yahoo! Groups for sending higher volumes of messages with mailing list distribution options. Yahoo! Groups is better designed for sending large numbers of outbound messages on a regular basis.
• Try Constant Contact: Partners with Yahoo! Small Business, try using Constant Contact for sending higher volume messages.
