What We'll Cover in 15 Minutes

Diagnose Your Deliverability

We'll look at your domain reputation, authentication setup, and sending infrastructure to pinpoint why your emails aren't reaching inboxes.

Map Out the Fix

You'll leave with a clear understanding of what needs to happen — whether that's working directly with Microsoft, cleaning up your data, or reconfiguring your infrastructure.

Identify Data Hygiene Risks

Bad data is the #1 reason deliverability tanks. We'll discuss whether your lists have hidden landmines — outdated contacts, departed employees, or addresses flagged by security systems.

This call is 100% free — no obligation, no pitch. If we can help further, we'll let you know what that looks like. But the call itself is about giving you answers.

I've built my career around improving email deliverability. I founded Unlock The Inbox, Zerobounce, Postbox US, and Campaign Cleaner — each focused on enhancing different aspects of email performance.

 

I specialize in B2B data hygiene and Office 365 deliverability. Poor deliverability is often caused by bad data, which is the #1 reason response rates plummet. It doesn't just affect inbox placement — it can damage your sender reputation and get you blacklisted.

 

When I talk about data hygiene, I'm not just referring to running your list through a basic email validation tool. Those tools are often the reason you got in trouble in the first place — labeling addresses as "valid" when they aren't. In the email validation world, "valid" just means the email didn't bounce. It doesn't mean the person is real, reachable, or still with the company. I help you identify and remove emails tied to people who've moved on, retired, or passed away — and where possible, find the real email address instead.

 

I've seen email addresses continue "engaging" with campaigns — opening and clicking — even years after the owner passed away. Why? Because advanced email security systems like Proofpoint, Mimecast, and others simulate clicks and opens while scanning for threats. These systems also monitor how many inactive or non-existent addresses you're sending to, which can quietly damage your reputation.

 

Many outreach lists built through tools like Apollo, Seamless, or RocketReach include outdated contacts and multiple emails per lead. These platforms are essential for outbound work — but identifying the hidden landmines in that data? That's where I come in.

 

I'm proud to be one of the few individuals listed on the DMARC Standard, having contributed to one of email's core security frameworks. Over the years, I've worked with Fortune 500 companies and small businesses alike to refine their email strategies and drive better results.

 

With a strong background as a developer and coder, I specialize in automating processes and building tools to solve unique challenges. This technical expertise allows me to deliver customized solutions that simplify complex tasks, save time, and boost efficiency.

 

I understand that every company's email needs are different — whether you're sending product announcements, weekly promotions, sponsored content, affiliate campaigns, website traffic drivers, or cold outreach. Let's work together to ensure your email campaigns perform at their best.
