Stop Landing in Spam.
Start Dominating the Inbox.

ThunderSteed’s Email Deliverability Audit provides root cause diagnosis + a prioritized action plan. Our proven process gets emails flowing into the primary inbox and keeps them there.

Your emails are getting delivered...
but are they being seen?

There's a stark difference between delivery and deliverability. Delivered is just the acceptance of your email by mail box providers. Deliverability is whether your email makes it into the primary inbox or the spam/junk folder. Every filtered email due to deliverability issues is wasted budget. Some of the symptoms that indicate you have a deliverability issue follows:

Diminishing Rates

Open and click-through rates dropping month after month with no clear technical reason.

Promo / Junk / Spam

Messages landing outside the primary inbox on Gmail, Outlook & Yahoo.

Reputation Hits

Your domain appearing on Blacklists or sudden drops in sender reputation.

“Fine” But Broken

Everything appears to be correct, yet primary inbox placement remains poor.

Deliverability & Inbox Placement Solved

Frequently Asked Questions

What do I need to get started with an Email Deliverability Audit?

The more data points you share, the more in-depth the analysis will be. Working with a rich data set results in the development of a more effective action plan. The data points we are most interested in follows:

  • Infrastructure Info: Current DNS records, ESP/sending servers, sending domain(s).
  • Performance Data: 3-6 months of emails sent, open rates, CTR, bounce, unsubscribes and spam complaints
  • Sending frequency: Current volume, projected list growth and volume spikes attributed to seasonal or special events.
  • Content & Operational: Recent examples or raw HTML/headers of standard marketing emails, newsletters, or automated transactional flows.
  • Subscriber acquisition process: how you collect your data, onboarding, segmentation and list hygiene.

How is this different from free tools or a basic checklist?

Free tools are generally good at finding issues, they mostly target symptoms in isolation. Our audit does a deep dive to get the complete picture and diagnose root causes across authentication, reputation, list health, content, and infrastructure. Our audit provides you with a prioritized action plan tailored to your business, audience and volume.

Do I need to be on Pegasus Mail?

No. We audit any ESP or custom setup. While clients may choose to move to Pegasus if an infrastructure issue is discovered, you don't need to be currently on Pegasus Mail to receive the benefits from an audit.

What if I’m already using your free Email Deliverability Checklist?

Free tools and checklists (including our own 10-step guide) are good at pointing out individual issues and fixing them in isolation. But they can't look at how the issues interact. And they also can't assess their combined effect on deliverability, engagement, and revenue.

A professional email audit, like the one ThunderSteed offers, examines the full picture. We check every part of the deliverability stack, authentication, sender reputation, list quality, content performance, and infrastructure. You receive a custom action plan for your business, audience, and volume. This way, you address the root causes instead of the symptoms.

Can this lead into ongoing help?

Absolutely! Many clients move from audit to implementation and ongoing support on a retainer basis. Or if you are experiencing issues with your current ESP or infrastructure, migrating to Pegasus Mail is also an option.

How should I prepare for Discovery?

We book a discovery session with you to learn more about your specific deliverability challenges. Our questions center around your current email marketing process and results. We'll get into metrics, what sending provider(s) you've worked with and any infrastructure issues you are currently facing.

We'll also want to see a few of your recent emails to get a feel for the design and content. Subject lines, sending frequency and how you're collecting subscriber data is also useful.

And of course, bring any questions you have about deliverability in general or our specific process.

How does the Design phase target my deliverability issues?

After our discovery call, we get to work analyzing the data you shared to perform a root cause analysis. Once we have determined the true issues, we design a remediation plan. We'll check all of the technical aspects to work out any bugs from authentication alignment to reputation scans before going over your challenges with a fine-tooth comb.

What does your process look like during Development?

With the root cause clearly identified during the design phase, we craft a custom action plan to remedy deliverability issues. Every finding is broken down into easy-to-understand snippets, detailing the steps required to eradicate the root cause of the issues.

The plan is then prioritized to focus on high-value items first. The result is an action plan that delivers quick wins, boosts marketing efforts, and generates a positive ROI.

How do we implement the Deployment?

With map in hand, it's time to discuss the findings and put the plan to work. We'll walk you through the key takeaways in your report. We’ll also go over the exact steps in the remediation plan. As you apply the recommendations, we track performance and offer additional optimizations if needed. Our deployment process ensures that your email deliverability issues are resolved quickly.
