Hadoop 3.2 4

You’re mentioning Hadoop 3.2.4. If you’re sending emails in bulk and want to ensure they don’t go to spam, here are a few tips:

1. Use a Reputable Email Service Provider: Choose a reliable email service provider with a good reputation for delivering emails to recipients’ inboxes.
2. Authenticate Your Emails: Implement authentication methods like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to verify the legitimacy of your emails.
3. Avoid Spam Trigger Words: Craft your email content carefully to avoid using words and phrases commonly associated with spam. These include terms like “free,” “urgent,” “act now,” and excessive use of exclamation points.
4. Personalize Your Emails: Avoid generic or overly promotional content. Personalized emails are less likely to be marked as spam.
5. Provide Unsubscribe Option: Include a straightforward way for recipients to unsubscribe from their emails. This helps improve your email reputation and reduces the chances of your emails being marked as spam.
6. Maintain a Clean Email List: Regularly clean your email list by removing invalid or inactive email addresses. High bounce rates can negatively impact your email deliverability.
7. Segment Your Email List: Divide your email list into relevant segments based on factors like demographics, interests, or behavior. This allows you to send more targeted and relevant content to each group.
8. Avoid Excessive Links and Attachments: Too many links or attachments in your emails can trigger spam filters. Keep your content concise and relevant.
9. Test Before Sending: Use tools to test your emails before sending them in bulk. This helps you identify any potential issues that trigger spam filters.
10. Monitor and Adjust: Monitor email engagement metrics and spam reports. Adjust your email content and strategies based on the feedback you receive.
