Sending emails with AWS Python SDK

Houston we have a problem. Not Houston. I’m the one with the problem. I need to send emails to my list of users but I know that some of these users were spam users. I need a way to send emails and also remove invalid emails from my system.

In the past I have used AWS .NET SDK to send emails and also track bounces and complaints. But I want to challenge myself so I want to play with the Python SDK. In this post, I want to share how to send emails using the AWS Python SDK.

Install the python SDK by following these instructions. Make sure to setup a profile that has permissions to send emails. In this example, I’m using a profile name “python-scripts” that has permissions to send ses emails. Make sure you set this name based on your setup.

After installing boto3, we are ready to create a class responsible to send emails. Take a look at EmailController.py below:

Now let’s create a class that uses EmailController.py. Take a look at EmailRunner.py.

I like to keep things simple. I have a csv file with all the email addresses. Each line in the csv file has an email address. Next, my class reads each line and sends an email. If there are any errors while sending the emails, I’ll use another csv file to keep track of these errors.

If we were able to send emails successfully, we will receive a valid response with status of 200.

That’s all for today. In a future post, I’m going to show you how to setup sns notifications for bounces and complaints. Have a nice day!

This is part 3 in a series dedicated to AWS CodeDeploy API using .NET SDK. In part 1, I created the CodeDeploy application using ASP.NET Core MVC, C#, and DynamoDB. In part 2, I created the deployment group which has settings for alarms, load balance, auto scaling groups, deployment styles, and other settings.

In this post, I want to concentrate on creating the deployment. In the deployment request, you can specify revision information (Github or S3 settings), deployment group, auto rollback configuration, and other settings.

Talk is cheap. Show me the code!

If you want to follow along, you can visit my github repo at https://github.com/agileraymond/DotNetDeployments. Now that you have a reference to the repo, let’s modify our controller so we can display our view.

This controller action displays our AddDeployment view.

There is a limitation with this view since it only displays S3 settings. In a future post, I will revisit this view and add the Github repo as well. I wanted to get something working in a short amount of time. When the user clicks on Add Deployment button, it will call a Post controller action to trigger a new deployment.

If the user entered all required information, a new deployment will be created in the AWS CodeDeploy console.

Have a nice day!
