Scripting Gmail

I needed to send emails around informing GreyBox users that a new GreyBox version is out. I could use Gmails interface, spend a lot of time, drink some coffee and take some drugs... But!
This is a little guide on how to search Gmail, parse the results and use the results to send some emails. Python baby!I love Python and it's freaking cool I can use my favorite language to script my favorite email application. Python Gmail library libgmail will be used. Get libgmail and install it by doing: python setup.py install Query the Gmail email databaseThe mission is to extract all the emails I got regarding the key word greybox. Here is the code that does that: import libgmail
import re
from sets import Set
re_email = re.compile('.*"_upro_(.*?)".*')
re_author = re.compile('.*>(.*)<.*')
def getEmails(query):
ga = libgmail.GmailAccount("amix3k@gmail.com", "mypw")
ga.login()
messages = ga.getMessagesByQuery(query, True)
emails = Set()
for m in messages:
auths = m._authors
r_author = re_author.match(auths).groups()[0]
r_email = re_email.match(auths).groups()[0]
emails.add((r_author, r_email))
return emails
for a, email in getEmails('greybox'):
print "%s, %s" % (email, a)
Running this script will print out following: johndoe1@email.com, John Doe 1 johndoe2@email.com, John Doe 2 johndoe3@email.com, John Doe 3 We will put the emails in a file called emails: python get_emails.py > emails Now one can filter emails manually and remove some emails of people that already know that GreyBox 3 is out. Send an email to peopleSending email is rather trivial, here is the needed code that will send an email to everyone in the file emails: import libgmail
ga = libgmail.GmailAccount("amix3k@gmail.com", "mypw")
ga.login()
def sendEmail(to_email):
subject = "GreyBox 3 released"
msg = """GreyBox 3 is released :)
The new version features...

gmsg = libgmail.GmailComposedMessage(to_email, subject, msg)
ga.sendMessage(gmsg)
for l in open("emails"):
email, author = l.split(", ")
sendEmail(email)
Save this in a file called send_emails.py and run it: python send_emails.py The endThis is the end - the end my friend :) Hope you enjoyed this.
