I can provide information about Machine Learning on Google Cloud. Google Cloud offers a wide range of machine learning services and tools to help businesses build and deploy ML models. Some of the key offerings include:

1. Google AI Platform: This is a fully managed platform for building, deploying, and scaling machine learning models. It provides tools for data preparation, model training, hyperparameter tuning, and model deployment.

2. TensorFlow on Google Cloud: Google Cloud provides support for TensorFlow, an open-source machine learning framework. You can use TensorFlow on Google Cloud to build and train your custom machine learning models.

3. BigQuery ML: Google BigQuery, a serverless, highly scalable data warehouse, also has machine learning capabilities. You can use SQL queries to build and train machine learning models directly within BigQuery.

4. AutoML: Google offers AutoML services for various tasks like image recognition, natural language processing, and more. These services are designed to make it easier for users with limited machine learning expertise to build models.

5. AI Hub: Google AI Hub is a repository of pre-built machine learning components and models. You can use these components to accelerate the development of your machine learning projects.

To ensure that emails regarding Google Cloud courses or services don’t go to spam, it’s important to follow best practices for email communication:

1. Use a reputable email service provider: Ensure that you are sending emails through a trusted email service provider that has a good reputation.

2. Authenticate your domain: Implement SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) authentication to verify that your emails are legitimate.

3. Use a clear and relevant subject line: Make sure your email subject line clearly indicates the content of the email and is not misleading.

4. Provide valuable content: Ensure that the content of your email is relevant and provides value to the recipients.

5. Avoid spammy content: Do not use excessive capitalization, exclamation marks, or spammy words in your emails.

6. Optimize for mobile: Many people read emails on their mobile devices, so make sure your emails are mobile-friendly.

7. Include an unsubscribe option: Allow recipients to easily opt out of future emails if they wish.
