Ensuring Optimal Email Deliverability: How Postmastery Console Enhances Moosend’s Daily Operations

Since 2017, Moosend has partnered with Postmastery, a crucial part of our daily operations. The tool provides exceptional support and has been instrumental in past migration processes.

Using Postmastery Console, we can swiftly identify and resolve issues, enhancing email performance for all our clients.

This collaboration ensures we maintain high deliverability standards and a strong sending reputation to benefit our clients’ email campaigns and overall success.

What is Postmastery Console?

Postmastery Console is a specialized tool designed to optimize email deliverability and monitor email performance.

It offers a comprehensive suite of reporting and analytical features that enable email service providers (ESPs) to understand and improve their clients’ email campaigns.

What We Can See Through Postmastery’s Reporting Tool

Here’s what we can monitor:

Deliverability Dashboard:

• Overview metrics: Provides a high-level view of key metrics such as delivery rates, bounce rates, complaint rate, etc.

Detailed Reporting

• ISP-specific reports: Breaks down performance metrics by Internet Service Providers (ISPs) like Gmail, Yahoo, and Outlook, helping to pinpoint deliverability issues with specific providers. One of the things that also helps a lot is that they separate also Outlook and Office 365 email addresses as well.
• Bounce Analysis: Offers detailed reports on bounce types (soft, hard) and reasons, enabling better understanding and management of bounces.

Spam Complaint Monitoring

• Feedback loops: Integrates with feedback loops to monitor spam complaints across different ISPs.
• Complaint reports: Provides detailed reports on spam complaints to help identify problematic sending patterns or content.

IP and Domain Reputation

• Reputation tracking: Monitors the reputation of sending IPs and domains, using data from various reputation services.
• Blacklist monitoring: Checks against major blacklists and provides alerts if your IP or domain gets listed.

Authentication and Compliance

• SPF/DKIM/DMARC reporting: Monitors the status and alignment of SPF, DKIM, and DMARC for sent emails to ensure compliance and improve deliverability.
• Authentication failures: Reports on authentication failures to help troubleshoot and resolve issues.

Content Analysis:

• Spam Filter Tests: Analyzes email content to identify elements that may trigger spam filters.
• Content Scoring: Provides scores and recommendations to optimize email content for better deliverability.

Custom Reports and Alerts:

• Customizable Dashboards: Allows users to customize dashboards and reports to focus on the most relevant metrics, using a very friendly filtering system.
• Real-Time Alerts: Configures real-time alerts for critical issues like delivery failures, blacklistings, and spikes in spam complaints.

How Postmastery Helps Moosend

While my intention is not to promote Postmastery, I would like to share two key ways its reporting capabilities significantly benefit Moosend’s deliverability team in their daily operations.

1. Identifying authentication issues

A crucial aspect of email deliverability is ensuring proper email authentication.

Since Moosend headers are clear and all messages are delivered under the client’s domain name, Postmastery’s reporting helps us quickly identify when any major deliverability DNS mechanisms—DKIM, SPF, or DMARC—fail. For example, Postmastery can flag messages like:

and

By isolating a few bounced messages in Postmastery Console, we can identify all affected senders. Then, we promptly inform them of the necessary actions to rectify these issues, helping them boost both delivery and deliverability rates.

2. Isolating MPBs and Investigating Specific Senders

How many of you have encountered the following bounce reason in the past week, month, or even year?

I bet some of you see this every day.

However, with Postmastery’s Console tool, we can isolate the specific IP pool or IPs affected and review the history of those IPs and the senders associated with them.

The Console provides detailed insights including:

• Sender details: Names and email addresses of the senders.
• Sending volume: Volume of emails sent per day, month, or week to detect any unusual spikes.
• Complaint metrics: Number of complaints received.

These clues, when combined effectively, provide a clear picture of the IP’s performance and identify which senders are impacting it.

In such cases, we investigate the client’s campaigns and other relevant metrics such as unsubscribe rates, bounce rates, and how other major mailbox providers (MPBs) react to the campaigns of the specific user. If the findings are unfavorable, we place the account on hold until the client complies with our anti-spam policy.

Meanwhile, we work directly with Yahoo to resolve the issue without delays. This proactive approach ensures that we maintain high deliverability standards and protect our overall sending reputation.

By leveraging Postmastery’s detailed reporting capabilities, we can pinpoint issues quickly, take appropriate actions to mitigate them, and work collaboratively with ISPs to maintain optimal deliverability.
