Sending Email At the End of Your Process

Here is a nice script that will allow you to send emails at the end of your python script, or where ever you want to.  Today I just posted a comment on my topic of long running scripts, and I am adding this component onto my workflow, so I know when processes finish or that they have completed.

Enjoy

import arcpy
import smtplib
import os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
def send_mail(send_from, send_to,
              subject, text,
              f="",server="THE SERVER URL"):
    assert type(send_to)==list
    # Provide the name of your email server below
    #
    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject
 
    msg.attach( MIMEText(text) )
    if os.path.isfile(f):
        part = MIMEBase('application', "zip")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
        msg.attach(part)
    smtp = smtplib.SMTP(server)
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.quit()
def trace():
    import traceback
    import inspect
    import sys
    '''
    trace finds the line, the filename and error message and returns it
    to the user
    '''
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # script name + line number
    line = tbinfo.split(", ")[1]
    filename = inspect.getfile( inspect.currentframe() )
    # Get Python syntax error
    #
    synerror = traceback.format_exc().splitlines()[-1]
    return line, filename, synerror  
def main(*argv):
    try:
        #    User Inputs
        #
        server = argv[0]
        subject = argv[1]
        message = argv[2]
        recievers = str(argv[3]).split(';')
        #    Email Function
        #
        send_mail(
              "NOTIFICATION@DONOTREPLY.COM",
              recievers,
              subject,
              message,
              "",
              server)
        arcpy.SetParameterAsText(4,True)
    except:
        arcpy.AddError(arcpy.GetMessages(2))
        arcpy.AddError(str(trace()))
        arcpy.SetParameterAsText(4,False)
if __name__ == "__main__":
    argv = tuple(arcpy.GetParameterAsText(i)
            for i in range(arcpy.GetArgumentCount()))
    main(*argv)
