Understanding Email Blocklists and Our Commitment to Ensuring Incoming Email Deliverability

Introduction

As a valued customer, we understand how frustrating it can be when important emails are blocked or marked as spam. This article aims to shed light on why this happens, particularly with emails from major providers like Gmail, Outlook, and Hotmail, and to inform you about the measures we have taken to ensure you receive your emails without interruption.

Why Are Emails Being Blocked?

Email blocklists, also known as Real-time Blackhole Lists (RBLs), are used by email servers to identify and block emails from known sources of spam. This helps provide a secure and comfortable experience for users. These blocklists are maintained by independent services such as SpamCop and Spamhaus, which monitor and report spam activity. Those reports are, in turn, used by email servers to know where malicious activity originates.

The Conflict

In recent times, a conflict has emerged between major email providers (like Gmail, Outlook, and Hotmail) and independent blocklist services. Here's why:

1. High Volume of Traffic: Major providers handle a massive volume of email traffic daily. Inevitably, some of this traffic includes spam, phishing attempts, and other undesirable content.
2. Reputation-Based Blocking: Independent blocklist services operate based on domain and origin reputation. When they detect a significant amount of spam originating from a particular provider, they add the provider's IP addresses to their blocklists.
3. Increased Accountability: Traditionally, major providers were often given passes due to their dominance in the email market. However, independent services have recently adopted a stricter stance, holding these providers accountable for the spam originating from their networks.

Our Response and Commitment

We are committed to ensuring that our customers can receive emails from all legitimate sources, including major providers like Gmail, Outlook, and Hotmail. Here are the steps we have taken to address this issue:

1. Whitelisting Known IP Ranges: We have identified and whitelisted the known IP ranges used by major providers. This means that emails from these providers will bypass the blocklist checks, ensuring they reach your inbox.
2. Regular Updates: We regularly update our whitelisted IP ranges to accommodate any changes made by the providers. This helps maintain seamless email deliverability.
3. Continuous Monitoring: Our team continuously monitors email traffic and blocklist reports to identify and address any new issues promptly.

Despite these efforts, occasions do sometimes arise when incoming emails do not make it through. An example of when this may happen is if Gmail adds a new block of sending IP addresses that are not yet accounted for on our end.

What You Can Do

If you experience issues with receiving emails from specific senders, please follow these steps:

1. Report the Issue: Contact our support team with details about the sender and the email in question. This helps us investigate and resolve the issue quickly.
2. Whitelist Specific Senders: If you frequently receive emails from a particular sender, consider adding them to your personal whitelist in your email client or control panel like cPanel or Plesk.
3. Stay Informed: Keep an eye on our knowledgebase/forums for updates and best practices related to email deliverability.
