Scrapy – Sending an E-mail

  • Last Updated : 16 Mar, 2021

Prerequisites: Scrapy

Scrapy provides its own facility for sending e-mails which is extremely easy to use, and it’s implemented using Twisted non-blocking IO, to avoid interfering with the non-blocking IO of the crawler. This article discusses how mail can be sent using scrapy. 

For this MailSender class needs to imported from scrapy and then a dedicated function with correct parameters needs to be called to successfully send a mail.

Functions used

  • MailSender() is used to setup the mailer.

Syntax:

classscrapy.mail.MailSender(smtphost=None, mailfrom=None, smtpuser=None, smtppass=None, smtpport=None)

Parameters

  • smtphost (str or bytes) – the SMTP host to use for sending the emails.
  • mailfrom (str) – the address used to send emails (in the From: header).
  • smtpuser – the SMTP user.  If omitted, the MAIL_USER setting will be used. If not given, no SMTP authentication is going to be performed..
  • smtppass (str or bytes) – the SMTP pass for authentication.
  • smtpport (int) – the SMTP port to connect to
  • smtptls (bool) – enforce using SMTP STARTTLS
  • smtpssl (bool) – enforce employing a secure SSL connection
  • classmethodfrom_settings() Instantiates a Scrapy settings object, which can respect these Scrapy settings.

Syntax:

classmethodfrom_settings(settings)

Parameters

  • settings (scrapy.settings.Settings object) – the e-mail recipients
  • send() sends email to the given recipients.

Syntax:

send(to, subject, body, cc=None, attachs=(), mimetype=’text/plain’, charset=None)

Parameters

  • to (str or list) –the e-mail recipients as a string or as an inventory of string
  • subject (str) – the subject of the e-mail
  • cc (str or list) – the e-mails to CC as a string or as an inventory of strings
  • body (str) – the e-mail body
  • attachs (collections.abc.Iterable) – an iterable of tuples (attach_name, mimetype, file_object) where attach_name is a string with the name that will appear on the e-mail’s attachment, mimetype is the mimetype of the attachment and file_object  may be a readable file object with the contents of the attachment
  • charset (str) – the character encoding to use for the e-mail contents

Approach

  • Import module
  • Setup mailer
  • Add subject and body of the mail
  • Supply with sender and receiver e-mail addresses
  • Send mail

Example:

Python3




# import module
from scrapy.mail import MailSender
  
# setup mailer
mailer = MailSender(mailfrom="Something@gmail.com",
                    smtphost="smtp.gmail.com", smtpport=465, smtppass="MySecretPassword")
  
# send mail
mailer.send(to=["abc@gmail.com"], subject="Scrapy Mail",
            body="Hi ! GeeksForGeeks", cc=["another@example.com"])
