While sending an email message to a large group of people using different email service like Gmail, Yahoo, AOL, etc, there is a daily quote/limit. If you break the limit , your service provider will disable your account temporarily/permanently  without any warnings. Please read the following rules to avoid temporary shut down of email service by provider:

The following rules apply when sending emails from a Google Gmail account:

Rule 01: If you access Gmail via POP or IMAP clients (like Microsoft Outlook), you can send an email message to a maximum of 100 people at a time. Cross the limit and your account will be disabled for a day with the error “550 5.4.5 Daily sending quota exceeded.”

Rule 02: If you access Gmail from the browser, you may not address an email message to more than 500 people at a time. Try adding any more recipients in the To, CC or BCC field and your Gmail account will get probably disabled for 24-72 hours. Error: “Gmail Lockdown in Secton 4″

Rule 03: Always double check email addresses of recipients before hitting the Send button in Gmail. That’s because your account will get disabled if the email message contains a large number of non-existent or broken addresses (<25 ?) that bounce back on failed delivery.

The following restrictions apply when sending emails from a Yahoo Mail account:

Rule 01: If you access Yahoo! Mail from the browser, you may not address an email message to more than 100 people per hour. Don’t try adding any more recipients in the To, CC or BCC field.

Rule 02: If you access Yahoo! Mail via POP or IMAP clients , you can send an email message to a maximum of 10Mb per message for the free Yahoo Mail Service, or 20Mb per message for Yahoo! Mail Plus.

Rule 03: Always double check email addresses of recipients before hitting the Send button. That’s because your account will get disabled if the email message contains a large number of non-existent or broken addresses that bounce back on failed delivery.

AOL Mail: The following restrictions apply when sending emails from a AOL Mail account:

Rule 01: You cannot send more than 100 recipients per message or 500 recipients per connection
