Azure’s Language Understanding (LUIS) is a cloud-based conversational AI service that applies custom machine-learning intelligence to a user’s informal, natural language text to predict overall meaning and extract relevant, detailed information.

To ensure that an email about Azure LUIS, or any course related to it, does not go to spam when sent in bulk, here are some best practices to consider:

Use a Reputable Email Service Provider (ESP): Choose an ESP with a good reputation and follow best practices to ensure your email is delivered to the inbox.
Consent is Key: Ensure the recipients have opted in to receive your emails. Unsolicited emails are more likely to be marked as spam.
Clean Your Email List Regularly: Remove inactive users who haven’t engaged with your emails over a certain period. This improves your engagement rate, a positive signal to email providers.
Personalization: Use the recipient’s name and include content that is relevant to them. This can increase the email’s engagement rate, a positive signal to email filters.
Avoid Spam Trigger Words: Certain words and phrases can trigger spam filters. Be cautious with the language in your email’s subject line and content.
Clear Opt-Out Option: Always provide a straightforward way for recipients to unsubscribe from your mailing list.
Test Before Sending: Use services to check your email’s spam score before sending it out. This can help you identify and fix issues that could cause your email to be marked as spam.
Monitor Engagement: Keep track of how recipients interact with your emails. This data can help you to improve your emails and avoid spam filters continuously.
Follow Email Sending Limits: If you’re using your email server, be aware of the limits to how many emails you can send to avoid being blocked.
Include a Plain Text Version: Some recipients may use email clients that don’t display HTML content correctly. Including a plain text version ensures that everyone can read your email.
Proper Formatting and Design: Ensure your email is professionally designed, balances images and text, and is responsive across all devices.
Authenticate Your Email: Use SPF, DKIM, and DMARC records to authenticate your email, which can help to ensure your email is delivered to the inbox and not the spam folder.
