If you’re planning to send bulk emails and want to ensure they don’t end up in spam, you might want to consider these general tips:

1. Use Reputable Email Service Providers: Choose a reliable email service provider (ESP) with a good reputation for delivering emails to the inbox. Some popular ESPs include SendGrid, Mailchimp, and Amazon SES.
2. Authenticate Your Domain: Implement your domain’s SPF, DKIM, and DMARC records. These authentication methods help verify the authenticity of your emails and can improve deliverability.
3. Maintain a Clean Email List: Regularly clean your email list to remove invalid, bounced, or unsubscribed email addresses. Sending emails to valid and engaged recipients improves your sender’s reputation.
4. Avoid Spammy Content: Craft your email content carefully. Avoid using excessive capital letters, exclamation marks, and spam-triggering words.
5. Personalized Content: Personalized emails with relevant content are less likely to be marked as spam by recipients.
6. Use Opt-In Lists: Only email individuals who have opted in to receive your communication. Purchased or scraped email lists can lead to high spam rates.
7. Monitor Deliverability: Keep an eye on your email deliverability metrics, such as open rates, click-through rates, and bounce rates. This can help you identify and address potential issues.
8. Segmentation: Segment your email list based on user preferences, behaviors, and demographics. This allows you to send targeted content, which is more likely to be well-received.
9. Avoid Attachments and Links to Untrusted Sources: Attachments and links to suspicious websites can trigger spam filters. Ensure that your links lead to legitimate and secure destinations.
10. Test Emails: Send test emails to different email providers to check how they are displayed and if they end up in the inbox.

Remember that even with these precautions, there’s no guarantee that all emails will always avoid spam folders. Various factors can influence email deliverability, including recipient behavior and changing spam filter algorithms.
