Email to HTML Script

/ Published in: Python

A script to parse emails and return HTML suited for email blast programs

Highlighted TextExpand

user = ("username")

# connecting to the gmail imap server
m = imaplib.IMAP4_SSL("imap server")
m.login(user,pwd)
m.select("INBOX") # here you a can choose a mail box like INBOX instead
# use m.list() to get all the mailboxes

resp, items = m.search(None, "ALL") # you could filter using the IMAP rules here (check http://www.example-code.com/csharp/imap-search-critera.asp)
items = items[0].split() # getting the mails id

for emailid in items:
    resp, data = m.fetch(emailid, "(RFC822)") # fetching the mail, "`(RFC822)`" means "get the whole stuff", but you can ask for headers only, etc

#  This script will access a set email account, parse the text and attachments of each email, create HTML markup
#  and zip the files together. This script assumes a set template for the HTML. I will most likely have to change
#  this in order to incorporate multiple templates. The HTML markup for each template will be sent in the email
#  and be parsed in the ame fashion as the `token` and `tag` variables above.
#
#  What still needs to be done:
#  1) Archive email after being zipped so that duplicates are not created
#  2) Email .zip file to requestor (person who ordered)
