Mail merge ruby script

The other day, I needed to send the gmail invite to all the folks in the development team and it amounted to more than 30 people. Since each one would have to be sent a different invite, distribution list won't work. Here is a quick Ruby script I cranked up to send the invites. Go ruby.

require 'net/smtp'



receiver_list = ['x@y.com','a@b.com']

invites_list = ['invite_url_1','invite_url_2']

smtp = Net::SMTP.start('mta1.mycompany.com', 25)

sender = 'me@gmail.com'



receiver_list.each_index {|email_index|

   receiver = receiver_list[email_index]

   invite_link = invites_list[email_index]

   puts "Sending e-mail to " + receiver 

   msgstr = "From: Venkat <#{sender}>\n"

   msgstr += "To: #{receiver} <#{receiver}>\n"

   msgstr += "Subject: Gmail invitation\n"

   msgstr += "I would like you to enjoy a small gift, a new Gmail account.\n"

   msgstr += "#{invite_link}\n\n"    

   msgstr += "Cheers,\n"    

   msgstr += "Venkat.\n"

   puts smtp.send_mail(msgstr, sender, receiver)

}
