    reader = csv.reader(input_file) 
    data = list(reader) 
    text = text.format(table=tabulate(data, headers="firstrow", tablefmt="grid")) 
    html = html.format(table=tabulate(data, headers="firstrow", tablefmt="html")) 
    message = MIMEMultipart( "alternative", None, [MIMEText(text), MIMEText(html,'html')]) 
    message['Subject'] = "Your data" 
    message['From'] = me 
    message['To'] = you 
    server = smtplib.SMTP(server) 
    server.ehlo() 
    server.starttls() 
    server.login(me, password) 
    server.sendmail(me, you, message.as_string()) 
    server.quit()

In order to combine the data from both csv files, you need to be reading from both of them. A simple way to do this:

import csv
with open('csv1.csv', 'r') as csv1, open('csv2.csv') as csv2:
    reader1 = csv.reader(csv1, delimiter=',')
    reader2 = csv.reader(csv2, delimiter=',')
    all_text = str()
    for row in reader1:
        all_text += ' '.join(row) + '\n'
    for row in reader2:
        all_text += ' '.join(row) + '\n'
    print all_text

This will successfully combine the data from the csv files into a singular string. You can play around with the formatting of the all_text string. As for sending the email, it seems as though you can successfully do SMTP through python.

There is also a neat python package called mailmerge that templates emails from csv data https://github.com/awdeorio/mailmerge , I'm not sure if you are templating emails from csv file data, or what your motives are, but maybe this will be useful for you :)
