Key Points to Consider When Running a Newsletter Campaign:

1. Dedicated IP Address – Consider IP reputation. There are methods (both automatic and manual) to check key levels of threat, content, and reputation. You don’t want to end up in the “red zone.”
2. DKIM – DomainKeys Identified Mail. It’s a standard used to add a digital marker to each message sent, helping the recipient’s server confirm that the email genuinely comes from your organization.
3. Set Up a Valid MX Record – MX = Mail Exchange. An ISP may block your emails if it does not identify an MX setting for your server.
4. SPF – Another standard used to validate an email as being sent from an authorized mail server associated with your domain.

Bonus: Beyond the Technical Aspects, What You Can Do for Successful Campaigns:

1. Avoid Using “No Reply” Addresses – Besides killing communication from the start, there are settings on recipient mail systems that may send emails from “no reply” addresses directly to spam/junk.
2. Use an Active and Properly Filtered Subscriber List – Investing more time and effort yields better results.
3. Maintain a Consistent and Balanced Email Volume – The role of a bulk emailing service is to send many emails, but too many at once can be detrimental. Avoid sudden and drastic increases in volume (e.g., moving from 200 emails per week to 5000). This could raise red flags with certain ISPs.
4. Monitor Performance Metrics – Track if you experience an increase in hard bounces, unsubscribes, or even positive signals (opens & clicks). These are usually signs that adjustments may be needed.
