What Happens During the Diagnostic & Quick- Fix Session?

February 12, 2026

The Diagnostic & Quick-Fix session is where the real work happens. It’s not a sales call, it’s not a 15-minute consultation. You get a focused working session with someone who has rebuilt sender reputations across industries, diagnosed systemic email problems, and knows what questions to ask when something doesn’t add up.

Here’s what a typical session looks like.

Authentication and Configuration Review

We start by mapping your authentication infrastructure. SPF, DKIM, DMARC, BIMI – but also how these interact with your ESPs, your sending domains, your DNS structure, and your reputation baseline. We’re looking for misalignments.

  • A technically correct SPF record that doesn’t match your actual sending infrastructure.
  • A DKIM setup that works with one provider but fails with another.
  • DMARC policy that’s either too lenient (missing fraud) or too strict (blocking legitimate mail).

This takes 15-20 minutes, but it often surfaces the first real problem. We’ve seen cases where a company thought their authentication was fine, but a DNS change six months prior broke their DKIM alignment, and no one noticed because the ESP dashboard showed green.

Reputation Analysis Across Mailbox Providers

We pull your sender reputation data from multiple vantage points: mailbox provider feedback loops, IP reputation databases, domain reputation history, complaint signals. We’re not just looking at whether your reputation is “good” or “bad” – we’re looking at where damage is happening, how consistent it is across providers, and what pattern explains the damage.

Sometimes reputation is genuinely healthy and your deliverability problem is technical. Sometimes reputation is silently degrading because of list quality, volume patterns, or behavior signals that aren’t obvious from your ESP dashboard.

Sometimes you have a sharp problem (a complaint spike following a campaign) that masks older systemic issues.

Behavior Pattern Assessment

We look at your sending patterns: volume, cadence, list age, engagement characteristics, language and link patterns. We look at how your sending has changed over time – sudden jumps, seasonal patterns, shifts in your target audience.

Mailbox providers care deeply about consistency, and deviations from established patterns often trigger filters or reputation degradation.

We also assess whether different email streams (cold outreach, transactional, marketing, lifecycle) are competing for the same reputation or properly segmented. This is where many companies discover their biggest problem: they’re sending both high-volume cold outreach and transactional email from the same domain, which means engagement issues in one stream tank the reputation of the other.

Tools and Monitoring Assessment

We review what data you’re currently collecting and what you’re flying blind on. Most companies have an ESP dashboard, maybe an email testing tool, maybe IP reputation monitoring. That’s often insufficient. We identify where you have real signal, where you’re interpreting noise as signal, and where you need new visibility.

For cold email senders, this often includes testing your deliverability in real mailboxes before campaign deployment. For ecommerce and transactional senders, it includes complaint monitoring and engagement rate tracking.

The Key Question

Somewhere in that session, we answer the diagnostic question: Is this a small fix or the tip of a bigger problem?

Sometimes the answer is clear immediately. “Your SPF has an error, we fix it, you’re done.” Sometimes it takes the full working session. “Your reputation is fine, but your sending volume is increasing faster than your domain trust, and that’s triggering temporary filtering that will get worse if you don’t change your ramp.”

Immediate Fixes

When we identify problems that can be fixed in the session, we walk you through them in real time. A DNS record correction. A configuration change in your ESP. A sending behavior adjustment. You implement it together, often during the call, so you see the change happening.

Sometimes these fixes solve your problem completely. Sometimes they’re just the beginning.

The Diagnosis

At the end of the session, you have clarity on what’s actually happening and why. You understand whether your problem is authentication, reputation, behavior, tooling, or some combination. You know whether this is a quick fix or requires more work. You know what the next step costs (nothing, or $2,500-$5,000 if you need scoped remediation, or $5,000-$15,000 quarterly if you need ongoing guidance).

The diagnostic typically costs $500. That $500 credits fully forward to any future engagement, so if you move to a scoped engagement, your net cost is whatever the scoped engagement costs minus $500.

We’d love to learn more about your business, email deliverability and outreach goals, and see if we might be able to help.

Whether you have questions about what we do, how Protocol works, or you’d just like to pick our brains on some of our best practices, we’d be happy to chat.

Senders Case Studies

See All Case Studies

Momofuku

Founded by chef David Chang, Momofuku is a renowned culinary brand with a nation-wide presence, including restaurants and an online store with delicious goods. They ran into an issue with their email sending – high bounce rates and blocked sending. With hundreds of thousands of people on their email lists eager to stay informed, and an impeccable reputation to uphold, Momofuku wanted to nip this problem in the bud quickly.

  • Momofuku reached out to Senders to run a diagnostic test on their sending infrastructure and find the root cause
  • Senders deliverability experts discovered an issue with their DMARC, which was preventing emails from being sent, as their WordPress wasn't aligned with their SPF
  • Senders provided the most effective solution helping Momofuku restore safe sending, and suggested next steps to ensure everything keeps running smoothly on their end
  • The client reported that Senders helped identify the problem and got them back on track 

Andrew Yeung

Where many others see a problem, Andrew sees an opportunity. His work may center around product leadership at Google (and previously Meta), but his true calling is all about bringing brilliant change-makers together.

How it started: Andrew hosted small-scale dinners for a handful of people at the peak of the pandemic in NYC, to enable safe connections during the most isolating times. How it’s going: His events now count as many as 2,000 tech leaders each, and he has set up 100+ such parties for more than 15,000 people in the past couple of years. Andrew understands that if two minds are better than one, putting two thousand together, preferably in the same room, can make a profound difference.

Given the impact of his community-building efforts, people want him to be able to reach out – and email is often the best way to do so. So, we helped out a bit.

  • Andrew came across deliverability issues that prompted him to get in touch with Senders and look into the best possible solutions
  • The Senders team made the necessary domain configuration adjustments, with a focus on the domain’s email authentication settings to enhance security and deliverability
  • The SPF record was updated to include “Brevo” (Sendinblue) to strengthen authentication and reduce the chance of landing emails into spam
  • The DMARC policy update enabled better readability of DMARC reports for human analysts, which is essential for preventing email spoofing and phishing
  • Senders fixed the missing DKIM setup with Google, so that it now shows the email hasn’t been tampered with in transit
  • As a result, the client now has better, more stable email deliverability and security

Myrina.ai

Stands out as a trailblazer in empowering women entrepreneurs through technology and a supportive community.

Myrina.ai offers a cutting-edge range of AI-powered SaaS marketing and sales tools that cater specifically to female entrepreneurs and women-led businesses. Myrina.ai enables users to automate marketing and sales, while helping them scale their authentic selves while saving time and boosting conversions. Their Myrina’s Army community fosters a supportive platform that champions female entrepreneurs and their values, empowering them to conquer barriers and achieve their business goals. The company's dedication to providing not only top-notch technological solutions but also a platform for networking and mentorship underscores their commitment to fostering success among women in the entrepreneurial space.

Naturally, they wanted to make sure their email sending infrastructure was set up correctly to protect their reputation and successfully reach their recipients. Our deliverability team worked with the client’s team on:

  • Aligning the client’s three domains with Amazon to make sure they are compatible and optimized in order to integrate with Amazon’s system
  • Setting up a proper DMARC policy to protect their domains against unauthorized use and phishing scams
  • Enhancing email deliverability as well as security, so that each email sent from these domains can be properly authenticated and more likely to land in the right inbox
  • As a result, the client can protect the reputation of their business and domains, while safely sending out their email campaigns

Physician’s Choice

Sometimes the sheer number of options of any product can be daunting – how on earth do you pick the right one? This is especially true with supplements, as we can find them just about anywhere, but we can rarely understand a third of the ingredients listed. Unlike most, Physician’s Choice provides supplements with pure, potent ingredients that work. No fillers or “proprietary” blends with unidentified ingredients. They do the research, so you don’t have to.

  • The client’s team spotted issues with DMARC failures in Google Postmaster
  • The Senders deliverability team worked with the client to update the DMARC configuration to enable report collection
  • The client is now able to obtain detailed reports to diagnose the exact causes of the failures and prevent them in the future with proper DMARC setup
