Sending Email and Text Messages in python

 

Sending Emails in Python

Emails are a fundamental way of communication, and Python provides a straightforward way to send them programmatically. Using Python, you can automate sending emails, which is particularly useful for sending notifications, reports, or updates.

Key Concepts:

  • SMTP (Simple Mail Transfer Protocol): Python’s built-in smtplib library allows you to connect to an email server and send emails using the SMTP protocol.

  • Email Formatting: With the email.mime module, you can create well-formatted email messages, including adding attachments, setting the subject, and more.

Sending Text Messages in Python

Text messages (SMS) are another crucial way to communicate, especially for sending short, urgent messages. Python can be used to send SMS messages using APIs provided by services like Twilio.

Key Concepts:

  • Twilio API: Twilio is a popular service that provides APIs to send SMS messages. You’ll need to sign up for an account, get your API credentials, and a Twilio phone number.

  • REST API: The Twilio API is a REST API, meaning you can interact with it using HTTP requests, which Python can easily handle with the twilio library.

Why Use Python for Emails and Text Messages?

  • Automation: Automate the sending of emails and SMS based on triggers like time, events, or user actions.

  • Integration: Integrate messaging capabilities into your applications, like sending alerts, OTPs, or marketing messages.

  • Efficiency: Handle large volumes of messages with ease, ideal for newsletters, notifications, and customer support.

Connecting to an SMTP Server


If you’ve ever set up Thunderbird, Outlook, or another program to con-nect to your email account, you may be familiar with configuring the SMTPserver and port. These settings will be different for each email provider, but a web search for <your provider> smtp settings should turn up the server andport to use.

The domain name for the SMTP server will usually be the name of your email provider’s domain name, with smtp. in front of it. For example,Gmail’s SMTP server is at smtp.gmail.com. Table 16-1 lists some common email providers and their SMTP servers. (The port is an integer value and will almost always be 587, which is used by the command encryption stan-dard, TLS.)


Table 16-1: Email Providers and Their SMTP Servers

Provider SMTP server domain name

Gmail                                 smtp.gmail.com

Outlook.com/Hotmail.com smtp-mail.outlook.com

Yahoo Mail                         smtp.mail.yahoo.com

AT&T                                  smpt.mail.att.net (port 465)

Comcast                             smtp.comcast.net

Verizon                               smtp.verizon.net (port 465)


Once you have the domain name and port information for your email provider, create an SMTP object by calling smptlib.SMTP(), passing the domain name as a string argument, and passing the port as an integer argument.The SMTP object represents a connection to an SMTP mail server and has

methods for sending emails. For example, the following call creates an SMTP object for connecting to Gmail:


Sending the SMTP “Hello” Message

Once you have the SMTP object, call its oddly named ehlo() method to “say hello” to the SMTP email server. This greeting is the first step in SMTP and is important for establishing a connection to the server. You don’t need to know the specifics of these protocols. Just be sure to call the ehlo() method

first thing after getting the SMTP object or else the later method calls will result in errors. The following is an example of an ehlo() call and its return value:


Be careful about putting passwords in your source code. If anyone ever copies your program, they’ll have access to your email account! It’s a good idea to call input() and have the user type in the password. It may be inconvenient to have to enter a password each time you run your program, but this approach will prevent you from leaving your password in an unencrypted file on your computer where a hacker or

laptop thief could easily get it.
