Warming Up Emails and Dedicated IP

Hi Heet Bhimani,

Please go through the below steps and aws documentation links i hope it will helps to resolve your issue.

1. Warming Up Emails on a Warmed-Up IP

If your dedicated IP is already warmed up, you generally do not need to warm up individual email addresses. The main goal of IP warm-up is to establish a good reputation with ISPs by gradually increasing email volume. Once your IP has a solid reputation, it can be used for various email addresses, provided you follow best practices for content and engagement.

Monitor New Addresses: Even with a warmed-up IP, closely monitor the performance of emails from new addresses to ensure they do not negatively impact your IP's reputation. Poor engagement or high complaint rates from a new address can still cause issues.

2. Best Practices for Using Dedicated IPs

A. Number of IPs Required

For sending around 50,000 emails per day, a single dedicated IP should generally suffice if it is well-maintained and warmed up. However, consider the following:

Scalability: If you anticipate higher email volumes in the future, plan for additional IPs to distribute the load and maintain deliverability. Segmentation: Use multiple IPs to segment different types of email traffic (e.g., transactional vs. marketing emails) to manage and isolate reputation.

B. Best Practices for Managing Dedicated IPs

Gradual Ramp-Up:

Even with a warmed-up IP, gradually increase email volume. Monitor ISP feedback and engagement metrics such as open rates and bounce rates.

Consistent Sending Patterns:

• Maintain a steady and consistent sending volume to avoid triggering ISP filters.
• Spread out your email sends evenly rather than sending them all at once.

Content and List Management:

• Send high-quality, relevant content to minimize complaints and unsubscribes.
• Use confirmed opt-in (double opt-in) methods to ensure list quality and engagement.
• Regularly clean your email list by removing inactive or invalid addresses.

Authentication:

• Implement DKIM, SPF, and DMARC to authenticate your emails, which improves deliverability.
• Monitor your domain’s reputation using tools like AWS SES's reputation dashboard.

Engagement Monitoring:

• Continuously monitor key engagement metrics such as open rates, click-through rates, and bounce rates.
• Respond promptly to negative feedback to protect your IP's reputation.

Handling Complaints and Bounces:

• Use feedback loops (FBL) to receive notifications of spam complaints and address them quickly.
• Properly handle bounces by categorizing them (soft vs. hard bounces) and removing hard bounces from your list.
