AOL also imposes a rate limit on an AOL member when a member exceeds the acceptable number of email messages sent in a given time period. Rate Limits have been put in place by AOL Mail to curtail abuse from spammers and ensure an enjoyable online experience. The maximum number of people you can send an email to is constantly changing so that spammers cannot find out what it is. If you need to send an email to a large group of people, please break your mailing list into the smallest groups possible.
