gmail-connector 1.0.2

Python module to, send SMS, emails and read emails

Gmail Connector

Python module to send SMS, emails and read emails in any folder.

As of May 30, 2022, Google no longer supports third party applications accessing Google accounts only using username and password (which was originally available through lesssecureapps)
An alternate approach is to generate apppasswords instead.

Installation

pip install gmail-connector

Env Vars

Environment variables can be loaded from any .env file.

GMAIL_USER='[e-mail]',
GMAIL_PASS='<ACCOUNT_PASSWORD>'

Env variable customization

To load a custom .env file, set the filename as the env var env_file before importing gmailconnector

import os
os.environ['env_file'] = 'custom'  # to load a custom .env file

To avoid using env variables, arguments can be loaded during object instantiation.

import gmailconnector as gc
kwargs = dict(gmail_user='EMAIL_ADDRESS',
              gmail_pass='PASSWORD',
              encryption=gc.Encryption.SSL,
              timeout=5)
email_obj = gc.SendEmail(**kwargs)

Usage

Send SMS

import gmailconnector as gc

sms_object = gc.SendSMS()
# sms_object = gc.SendSMS(encryption=gc.Encryption.SSL) to use SSL
auth = sms_object.authenticate  # Authentication happens before sending SMS if not instantiated separately
assert auth.ok, auth.body
response = sms_object.send_sms(phone='1234567890', country_code='+1', message='Test SMS using gmail-connector',
                               sms_gateway=gc.SMSGateway.verizon, delete_sent=True)  # set as False to keep the SMS sent
assert response.ok, response.json()
print(response.body)

More on Send SMS

:warning: Gmail's SMS Gateway has a payload limit. So, it is recommended to break larger messages into multiple SMS.

Additional args:

• subject: Subject of the message. Defaults to Message from email address
• sms_gateway: SMS gateway of the carrier. Defaults to tmomail.net
• delete_sent: Boolean flag to delete the outbound email from SentItems. Defaults to False

Note: If known, using the sms_gateway will ensure proper delivery of the SMS.

Send Email

import gmailconnector as gc

mail_object = gc.SendEmail()
# mail_object = gc.SendEmail(encryption=gc.Encryption.SSL) to use SSL
auth = mail_object.authenticate  # Authentication happens in send_email if not instantiated beforehand
assert auth.ok, auth.body

# Send a basic email
response = mail_object.send_email(recipient='[e-mail]', subject='Howdy!')
assert response.ok, response.json()
print(response.body)

To verify recipient email before sending. Authentication not required, uses SMTP port 25

import gmailconnector as gc

validation_result = gc.validate_email(email_address='[e-mail]')
if validation_result.ok is True:
    print('valid')  # Validated and found the recipient address to be valid
elif validation_result.ok is False:
    print('invalid')  # Validated and found the recipient address to be invalid
else:
    print('validation incomplete')  # Couldn't validate (mostly because port 25 is blocked by ISP)

More on Send Email

import os
import gmailconnector as gc

mail_object = gc.SendEmail()
auth = mail_object.authenticate  # Authentication happens in send_email if not instantiated beforehand
assert auth.ok, auth.body

# Different use cases to add attachments with/without custom filenames to an email
images = [os.path.join(os.getcwd(), 'images', image) for image in os.listdir('images')]
names = ['Apple', 'Flower', 'Balloon']

# Use case 1 - Send an email with attachments but no custom attachment name
response = mail_object.send_email(recipient='[e-mail]', subject='Howdy!',
                                  attachment=images)
assert response.ok, response.body
print(response.json())

# Use case 2 - Use a dictionary of attachments and custom attachment names
response = mail_object.send_email(recipient='[e-mail]', subject='Howdy!',
                                  custom_attachment=dict(zip(images, names)))
assert response.ok, response.body
print(response.json())

# Use case 3 - Use list of attachments and list of custom attachment names
response = mail_object.send_email(recipient='[e-mail]', subject='Howdy!',
                                  attachment=[images], filename=[names])
assert response.ok, response.body
print(response.json())

# Use case 4 - Use a single attachment and a custom attachment name for it
response = mail_object.send_email(recipient='[e-mail]', subject='Howdy!',
                                  attachment=os.path.join('images', 'random_apple_xroamutiypa.jpeg'), filename='Apple')
assert response.ok, response.body
print(response.json())

Additional args:

• body: Body of the email. Defaults to blank.
• html_body: Body of the email formatted as HTML. Supports inline images with a public src.
• attachment: Filename(s) that has to be attached.
• filename: Custom name(s) for the attachment(s). Defaults to the attachment name itself.
• sender: Name that has to be used in the email.
• cc: Email address of the recipient to whom the email has to be CC'd.
• bcc: Email address of the recipient to whom the email has to be BCC'd.

Note: To send email to more than one recipient, wrap recipient/cc/bcc in a list.

recipient=['[e-mail]', '[e-mail]']

Read Email

import datetime

import gmailconnector as gc

reader = gc.ReadEmail(folder=gc.Folder.all)
filter1 = gc.Condition.since(since=datetime.date(year=2010, month=5, day=1))
filter2 = gc.Condition.subject(subject="Security Alert")
filter3 = gc.Condition.text(reader.env.gmail_user)
filter4 = gc.Category.not_deleted
response = reader.instantiate(filters=(filter1, filter2, filter3, filter4))  # Apply multiple filters
assert response.ok, response.body
for each_mail in reader.read_mail(messages=response.body, humanize_datetime=False):  # False to get datetime object
    print(each_mail.date_time.date())
    print("[%s] %s" % (each_mail.sender_email, each_mail.sender))
    print("[%s] - %s" % (each_mail.subject, each_mail.body))
