Make sure you give some time for the changes reflect and then run the code. Otherwise, you may encounter the following error:. When we send a text message on email the content is treated as a simple text. But we can include HTML tags also inside the text below is an example:. You can see in the below screenshot we may receive a mail like this. Another screenshot will be the output window. Then we need to read the file to be attached in binary mode after which file has to be encoded.

We can use base64 encoding before sending mail. First, we need to create a text file that we will be sending in the mail as an attachment. We need to read the text file then use base64 for encoding, the encoded file will be sent now. Another way is by using the following imports in the python code. Which are native libraries in python? Below is the code for sending mail using python native libraries Libraries to be imported import smtplib from email.

The first good news about Python is that it has a built-in module for sending emails via SMTP in its standard library. No extra installations or tricks are required. You can import the module using the following statement:. To make sure that the module has been imported properly and get the full description of its classes and arguments, type in an interactive Python session:.

At our next step, we will talk a bit about servers: choosing the right option and configuring it. Here is a brief list of reasons:. If you prefer working in the local environment, the local SMTP debugging server might be an option.

For this purpose, Python offers an smtpd module. It has a DebuggingServer feature, which will discard messages you are sending out and will print them to stdout.

It is compatible with all operations systems. It will help you verify whether your code is working and point out the possible problems if there are any. Fake SMTP server imitates the work of a real 3rd party web server. In further examples in this post, we will use Mailtrap. Mailtrap is very easy to set up: you will need just copy the credentials generated by the app and paste them into your code.

Mailtrap makes things even easier. Go to the Integrations section in the SMTP settings tab and get the ready-to-use template of the simple message, with your Mailtrap credentials in it. It is the most basic option of instructing your Python script on who sends what to who is the sendmail instance method:. The code looks pretty straightforward, right? To catch errors, we use the try and except blocks. Once you get the Sent result in Shell, you should see your message in your Mailtrap inbox:. In most cases, you need to add some formatting, links, or images to your email notifications.

We can simply put all of these with the HTML content. For this purpose, Python has an email package. In Python, it is handled by the email. It means that such a message has two rendering options accordingly. The next step in mastering sending emails with Python is attaching files.

I recommend that you use the standard packages email and smtplib together to send email. Please look at the following example reproduced from the Python documentation.

For sending email to multiple destinations, you can also follow the example in the Python documentation :. As you can see, the header To in the MIMEText object must be a string consisting of email addresses separated by commas. On the other hand, the second argument to the sendmail function must be a list of strings each string is an email address.

So, if you have three email addresses: person1 example. From your questions I gather that you have not gone through the Python tutorial - it is a MUST if you want to get anywhere in Python - the documentation is mostly excellent for the standard library. When I need to mail in python, I use the mailgun API wich get's a lot of the headaches with sending mails sorted out. You can also track events and lots more, see the quickstart guide. I'd like to help you with sending emails by advising the yagmail package I'm the maintainer, sorry for the advertising, but I feel it can really help!

Note that I provide defaults for all arguments, for example if you want to send to yourself, you can omit TOif you don't want a subject, you can omit it also. Furthermore, the goal is also to make it really easy to attach html code or images and other files.

Also, if you set it up once, you'll never have to enter the password again and have it safely stored. In your case you can do something like:. I'd invite you to have a look at the github or install it directly with pip install yagmail.

While indenting your code in the function which is okyou did also indent the lines of the raw message string. But leading white space implies folding concatenation of the header lines, as described in sections 2. Each header field is logically a single line of characters comprising the field name, the colon, and the field body. In the function form of your sendmail call, all lines are starting with white space and so are "unfolded" concatenated and you are trying to send.

Other than our mind suggests, smtplib will not understand the To: and Subject: headers any longer, because these names are only recognized at the beginning of a line.

Instead smtplib will assume a very long sender email address:. The solution is simple: Just preserve the message string as it was before. This can be done by a function as Zeeshan suggested or right away in the source code:. Note that I was also preserving the empty line between headers and body to accommodate section 3. Make sure you have granted permission for both Sender and Receiver to send email and receive email from Unknown sources External Sources in Email Account.

As far your code is concerned, there doesn't seem to be anything fundamentally wrong with it except that, it is unclear how you're actually calling that function. If you lookup the getreply function in smtplib excerpt belowyou will get an idea.You can specify IP address of the host or a domain name like tutorialspoint. This is optional argument. Usually this port would be An SMTP object has an instance method called sendmailwhich is typically used to do the work of mailing a message.

Here, you have placed a basic e-mail in message, using a triple quote, taking care to format the headers correctly. An e-mail requires a FromToand Subject header, separated from the body of the e-mail with a blank line.

To send the mail you use smtpObj to connect to the SMTP server on the local machine and then use the sendmail method along with the message, the from address, and the destination address as parameters even though the from and to addresses are within the e-mail itself, these aren't always used to route mail.

Unless you are using a webmail service such as Hotmail or Yahoo! When you send a text message using Python, then all the content are treated as simple text. While sending an e-mail message, you can specify a Mime version, content type and character set to send an HTML e-mail. Then, text and attachment sections can be specified within boundaries. A boundary is started with two hyphens followed by a unique number, which cannot appear in the message part of the e-mail.

A final boundary denoting the e-mail's final section must also end with two hyphens.

I thought it would be helpful to write up a tutorial on how to send emails with Gmail as the provider using Python.

Sending Emails in Python — Tutorial with Code Examples

This may not come as a surprise, but of course Python already has a library that lets you connect to an SMTP server, like the one Gmail uses.

This library is called, predictably, smtplib and comes included with Python. SMTP is a delivery protocol only, so you can't actually retrieve email with it, you can only send email, which is what we'll be focusing on in this article.

I should note that many email services, like Gmaildon't usually use SMTP on their internal mail servers. SMTP is usually just provided as an outward-facing interface to their service via the smtp.

This connection is unencrypted and defaults to port However, the protocol for mail submission actually useswhich is what we'll use. These connections are really simple to create with smtplib. The unencrypted version can be created with:. And that's it. There really isn't much more to it than passing the server address, port, and calling.

Using this server object you can now send email over an insecure connection. Note: You might not be ready to send emails quite yet. Gmail imposes some restrictions on SMTP connections like this. See the section "Authenticating with Gmail" below for more info.

Needless to say, you should always use a secured connection.What do you need to send an email with Python? Some basic programming and web knowledge along with the elementary Python skills.
