Bulk Mail Tool (C # Edition)

Introduction

It is often necessary to be involved in organizing community activities that involve communicating with different people, and the same email is an indispensable way.

The general bulk of the mail is not very friendly, if it is one-on, the person receiving the mail will be more attention, but also his name in the inside.

So take some time to write a tool, using C # to make a mail-sending tool is very simple.
