It is very useful for managing email accounts of multiple customers/users. Also, it helps in creating customized emails to send bulk mails to all users using templates. The customer support service offered by this software is really great. I have used several other mail management softwares like Zimbra etc., but nothing compared with Intrigua! Nothing as such. However its price point makes me think that their services are not worth while considering the features they offer. Manage emails of multiple users easily and quickly.
