The software sends e-mail to a list directly without smtp server setting.
Multi-Email Sender is a software which sends e-mail to a list of e-mail adresses in HTML or plain format.
What differs from a standard e-mail tool is that it does not need any specific configuration:
1) It does not need any host name for sending e-mail (SMTP server). It acts as an SMTP relaying software.
2) It does not need DNS name setting : It retrieves the DNS number automatically.
The software is a must for organizations which sends periodic e-mails to a mailing list. It has a control mechanism which validates e-mail addresses in the list, seperates the failed and the successful ones into the text files and generates a log file for errors occured.

In case of interruption such as internet disconnection or closure of the software, It saves the last actions and resumes its processes.

There is also an option to send emails by means of SMTP server for who want to use it.
