The inbox is earned by engagement.
SPF, DKIM and DMARC get your mail to the door. What happens next is decided by how people respond to it. I’m Chuck Mullaney, an email expert, and I help senders earn the inbox with sharper segmentation, email worth reading, and proprietary tools no one else has.

Authentication is the price of entry. It is not the strategy.
Every serious sender authenticates now. Gmail and Yahoo have required it of bulk senders since February 2024, along with spam complaints under 0.3% and one‑click unsubscribe. Getting it right is necessary. It no longer sets anyone apart.
What governs placement in 2026 is engagement: whether the people you mail actually open, read, reply and keep you out of the spam folder. Mailbox providers watch that behavior closely, and it comes down to two things you control.
Experience tells me where to look. Proprietary tools, built in house and not available anywhere else, show me what is actually happening inside your account.
- Segmentation
- Sending each message to the people most likely to want it, and safely bringing back the ones who have gone quiet.
- Writing
- Mail that reads like it came from a person worth hearing from, not a broadcast.

Illustrative summary, not measured data.
The inbox changed. Most playbooks did not.
Gmail and Yahoo bulk‑sender rules
Authentication, complaint thresholds and unsubscribe handling are enforced, not suggested. Miss them and you are throttled or blocked.
Apple Mail Privacy Protection
Pre-loaded images inflate opens across a large share of most lists. Segments built on opens rest on a number that no longer means what it used to.
One‑click unsubscribe, RFC 8058
Required for bulk mail. Done well, it protects your reputation. Done badly or skipped, it quietly wears it down.
AI agents in the inbox
Assistants increasingly sort, summarize and filter mail before a person sees it. Genuine engagement and a clean reputation count for more now, not less.
“Chuck has his finger on the pulse with all things email, from the technical side to the strategic, from legacy tech to cutting-edge AI. You can be 100% certain he’s going to deliver an A+.”
Where I help.
Every engagement starts with a free conversation with an email expert. These are the areas it most often leads to.
- List management
- Engagement-based segmentation and list hygiene, plus a proprietary, safe way to automatically re-engage subscribers who have not opened in months.
- Copy & design
- Email that reads like a person, not a broadcast, and drives action without tripping spam filters.
- Strategy development
- A custom email strategy aligned to your goals, your audience, and the revenue you are leaving on the table.
- Automation setup
- Sequences that nurture leads and drive sales on their own, built to keep engagement and reputation high.
- Inbox deliverability
- Authentication, reputation monitoring and infrastructure. The baseline, set up properly and kept that way.
- Training & support
- Hands-on training and ongoing support, so your team can hold the line long after our engagement ends.
“Chuck’s expertise is off the charts. His unique copywriting strategy and philosophy is something you don’t hear about anywhere else, and it flat out works. We’re coming back with a vengeance.”
How it works.
Speak with an email expert Free
A private conversation about how your mail is performing and where engagement and revenue are leaking. You leave knowing what to fix first, whether or not we work together.
The audit
Proprietary analysis pulls far deeper engagement data from your account than a standard review. Together we pinpoint exactly where engagement is being lost, and you get a written strategic plan to win it back, in priority order.
Implementation Optional
Fix the infrastructure, rebuild segmentation and sending, and recover reputation where it has slipped. The result is higher inbox placement and engagement, and more revenue from the list you own.
“We went from 2-3% open rates to breaking down doors, as high as 25%, within as little as two weeks with Chuck manning our campaigns. He delivered results, not with his mouth like so many marketers, he delivered.”
“We were making millions per month with our email and thought we knew it all, until Chuck arrived. His years of experience poured fuel on the fire and had our team performing at levels that would have otherwise taken years to develop. If you have the chance, grab him.”
Questions people ask before booking.
If yours is not here, bring it to the call.
What does the audit cover?
How you send, top to bottom: authentication, domain and IP reputation, list health, engagement segmentation, and the content patterns that trip spam filters. You come away knowing where revenue is leaking and what to fix first, in priority order.
How long does it take?
Most audits are delivered within a few business days. If you are in an active deliverability emergency, suddenly landing in spam ahead of a launch, that gets triaged immediately.
What do I need to provide?
Access to your sending platform or its reporting, your sending domains, and recent campaign data. You get a short checklist, and there is no engineering lift on your side to get started.
What does it cost to speak with an email expert?
Nothing. The first conversation with an email expert is free. If you decide to go further, the work is scoped to exactly what your account needs, so you only pay to fix the things that move revenue.
Which email platforms do you work with?
All the major ones: Klaviyo, ActiveCampaign, HubSpot, Mailchimp, Marketo, Iterable, SendGrid, Salesforce Marketing Cloud, and custom SMTP setups. Deliverability principles are platform-agnostic, so the fixes travel with you.
Can you fix a deliverability problem I have right now?
It is the core of the practice. Reputation recovery, getting out of Gmail and Yahoo spam, authentication and infrastructure, and meeting the bulk-sender requirements are the work I do every week.
Do you help with list management and segmentation?
Yes. Engagement-based segmentation and ongoing list hygiene are usually the fastest single lever on both deliverability and revenue. For subscribers who have not opened in months, I use proprietary technology that re-engages them automatically without putting your sender reputation at risk.
