ASP SendMail send static HTML

Background: Now almost every enterprise has to use the mailbox, and in the case of large customers, for our different levels of customers to send the holiday care, as well as our good news, new product notice to them is the problem we urgently need to solve. Effect

Ideas:

1, static Web template, first consider what needs to send, the need to make small and beautiful HTML static page to be sent when used;

2, about the issue of sending, click on the "Send mail" pop-up message box, fill in the theme, HTML server address, the recipient (multiple);

3, the realization of mass.

Code C #:

<summary>
Send failed email Address collection parameters
</summary>
private string Errormail;

Mass Mail Click event

protected void Btnsendmail_click (object sender, EventArgs e)
{
if (string. IsNullOrEmpty (Txtopic.value))
{
Messageshow ("Mail subject required");
Return
}
if (string. IsNullOrEmpty (Txurl.value))
{
Messageshow ("URL content required");
Return
}
if (string. IsNullOrEmpty (Txto.value))
{
Messageshow ("required by the addressee");
Return
}

string email = configurationmanager.appsettings["Managersendmailusername"].  ToString (); Login User Mailbox
String emailpwd = configurationmanager.appsettings["Managersendmailuserpwd"]. ToString (); Login User Mailbox Password


string s = Gethtmlcode (Txurl.value, "gb2312");
BOOL Restr = Sendmail (email, txto.value, Txtopic.value, True, S, "smtp.exmail.qq.com", email, emailpwd);
if (RESTR)
{
Clientscript.registerstartupscript (this. GetType (), "", "<script>alert (' all sent successfully! ');</script> ");
}
Else
{
Clientscript.registerstartupscript (this. GetType (), "",
"<script>alert (' sent, but the following address failed to send:" + Errormail + "may be the address does not exist!) ');</script> ");
}
}

Summary: This function is still very useful, we can expand, the timing of what to send, to achieve a variety of brilliant features. Finally say, I wish everyone the year of the goat, I hope things become!
