Bulk email refers to sending a large volume of personalized or identical messages to a list of recipients simultaneously. Unlike spam, legitimate bulk email is sent to individuals who have opted in to receive communications from your business, such as newsletters, promotional offers, or updates.

To send bulk email effectively and avoid being marked as spam, follow these key practices:

• Use a Dedicated Email Service Provider (ESP): Services like Mailchimp or Sendinblue manage deliverability, provide templates, and handle unsubscribe requests automatically.
• Build a Permission-Based List: Only email people who have explicitly agreed to receive your messages. Never purchase email lists.
• Include Clear Opt-Out Options: Every email must have a visible and functional unsubscribe link to comply with laws like the CAN-SPAM Act.
• Segment Your Audience: Send targeted content to specific groups within your list to increase engagement.
• Monitor Your Results: Track open rates, click-through rates, and bounce rates to improve future campaigns.

When sending from your hosting account, ensure your server is properly configured to prevent being blacklisted. Many hosting providers have strict policies on bulk email to protect their IP reputation. Consider using a third-party ESP or a dedicated SMTP service for large campaigns to ensure reliable delivery and maintain your website's performance.
