What is rate limit?

Most hosting email account providers allow users to send email by using the webmail browser interface or by using a SMTP connection with the email account SMTP server. No matter the way you send the emails (from web interface or email client software), you must be aware of the “rate limit” (the limit for sending emails per day) established by your email account provider, especially when you act bulk email marketing. It is always a good idea to contact your email account provider and ask about the email send rate, before proceeding with a mass email campaign.

Sample rate limit values

The following restrictions apply for Gmail, Hotmail and Yahoo.

Gmail email send limit – no more than 500 recipients per message for the Gmail web interface, or max 100 recipients if you are using an email client software.

Hotmail email send limit – no more than 100 recipients per day.

Yahoo Mail email send limit – no more than 100 emails or recipients per hour

The rate limit for popular hosting providers such as rackspace allows 2000 emails per day. If you need to send more than 2000 emails per day, you need to use some third party solution for your bulk email marketing.
