Many often there is a need for mass mailing( sending a mail to multiple recipients at a time). But sometimes it is odd to see lots of mail addresses in a mail, It reduces the importance of the mail to some extent or it may lead some misuses of the other recipients as well. Hence, it becomes necessary to a mass mail sender to take care of the mail address and to hide those from the other recipients except individuals. Bcc(Blind Carbon Copy) service can be used for mass mailing to overcome above mentioned problems. But while sending bcc we shouldn't forget to mention our own email address in To bar or to limit the number of recipients upto 50 in a day. Other wise The message will count as a spam message. You can add the recipients separating by a comma as we do in To bar. Kindly verify the emails before sending the mail otherwise many undelivered messages may cause to mark you as spammer. Some words should be avoided in the message like 'get back', 'following' etc. Hope you will enjoy the information. Thank you!
