Your emails go to spam. mailX shows you why, and how to fix it in seconds with clear answers and exact steps. Built for humans and AI agents. API and MCP ready.
@dawid_baranowski Appreciate it 🙌 That’s exactly one of the gaps we wanted to solve. A lot of these checks still require jumping between multiple tools and manual debugging steps.
Would really love to hear your feedback once you try it especially from someone already doing this stuff manually :)
@dawid_baranowski Love this. The raccoon copy is great. Your founders' entire fundraise depends on those emails landing in a VC inbox instead of the promotions tab, and a silent spam send is worse than a no because there's nothing for the founder to act on. Would love your feedback once you spin it up.
@othman_katim Exactly my thoughts. Causo sends emails from users' real emails, so adding a deliverability layer on top of this will be a big win. Look forward to integrating :)
Manual warmups and MX checks are exactly the kind of thing that shouldn’t stay manual for long. Curious to know how you have been doing it, care to share?
Love the 'no guesswork' approach. We check our SPF/DKIM/DMARC manually every month but the inbox placement algorithms change so fast it’s hard to keep up. Does mailX give real-time feedback on spam trigger words in the actual copy too?
@vikramp7470 Thank you !! And yes, that’s part of the broader problem we’re trying to solve. Authentication is foundational, but deliverability is also influenced by sending behavior and content quality.
On copy scoring: yes, Mailwarm has a spam checker that scores the email content before you send and flags the specific trigger words and patterns hurting placement. It's per-email scoring, you paste in the draft and get a verdict with the flagged issues. https://www.mailwarm.com/spam-checker
@vikramp7470 Today mailX is mainly focused on the technical layer: SPF, DKIM, DMARC, DNS, blacklists, infrastructure.
For copy/spam words, we already have a separatefree spam content checker in the Mailwarm ecosystem. But you’re right, full diagnosis should include both: setup + content + reputation. That’s where we’re heading.

This feels relevant for founders doing outbound. A lot of early teams depend on email but don’t really understand deliverability. Is it useful even for low sending volume?
@artstavenka1 Definitely! In some ways, low-volume founders are even more sensitive to deliverability issues because every email matters.
If you’re sending founder outreach, partnerships, recruiting emails, or early sales conversations, losing even a handful of emails to spam can have a real impact.
@artstavenka1 Yes, definitely. Low volume is actually the best moment to catch issues before they become expensive. If your setup, authentication, or reputation is weak, scaling only makes the problem bigger.
Before mailX, I spent 8 years in customer-facing roles sending endless follow-up emails. I even worked at a CRM SaaS where I blindly copy-pasted DNS records for users without a clue how they worked. Whenever an email vanished, my only troubleshooting advice was: "Uh, can you check your spam folder?"
Joining this team pulled back the curtain. I learned that hitting "send" triggers a massive technical engine, and when deliverability drops, the culprit is usually hidden deep inside it, like misconfigured DNS (SPF, DKIM, DMARC) or SMTP issues. For most teams, diagnosing this feels like reading ancient Greek.
That’s exactly why we built TheMailX. We wanted to strip away the guesswork for folks who just want their emails to land in the inbox without needing a computer science degree.
With TheMailX, you can:
Analyze your domain instantly: Pinpoint exactly where the delivery leak is happening in your email engine.
Generate what's missing: Get the exact records you need to fix the issue on the spot, no tedious Googling required.
Our goal is to make email deliverability easy to understand and even easier to fix. The team and I are live today, ready to answer your questions and hear how you’re handling deliverability. Let’s chat! 🚀
Love this perspective @manal_essalek1 . This is exactly why we built mailX: email deliverability should not feel like a black box reserved for technical people. Most teams just want to know what is broken and what to fix.
Proud to see the team turning years of customer pain into something simple, clear, and useful 🚀
When emails land in spam, the visible problem is simple: people don’t receive them. But the real work starts after that. You need to understand why it happened. Is it the domain setup? The sending behavior? The content? The reputation? Something else?
I’ve seen teams waste a lot of time trying random fixes because they don’t know what to prioritize first.
That’s the gap we wanted to close with mailX: help teams understand what is hurting their deliverability and what they should fix. Email can still be one of the strongest growth channels, but only if it actually reaches the inbox ;)
Many people think email marketing is hard, and I don’t blame them, because when you constantly send campaigns and replies drop or your open rates change, you would also have these same thoughts.
That’s why I really like the approach behind mailX: make the problem understandable first, then give clear steps to fix that problem.
Whether you’re a founder, sales team, marketer, or even building an AI agent that sends emails, the goal is the same, stop guessing and know what to improve to better deliverability.
I am excited to be part of this launch and to hear how people are currently handling deliverability.
Report
the "people see the data but dont know how to fix it" thing is painfully accurate tbh. been running cold email across a few warmed domains and half the battle is just figuring out where the problem even lives (client, workspace, auth, reputation).
btw does the mcp let an agent monitor deliverability continuously across multiple sending domains, or is it point-in-time per domain for now?
@saad_el_gueddari That’s exactly the problem we kept seeing 😅 Once you manage multiple warmed domains, half the battle is just figuring out where the issue actually comes from.
And yes the MCP can monitor deliverability continuously across multiple sending domains. The goal for us is to help agents (and humans) spot issues early instead of debugging after performance drops.
@saad_el_gueddari You nailed the diagnostic problem. Auth, reputation, workspace, and content all fail differently, and you can't fix what you can't locate.
On the MCP: today, it's point-in-time per domain. You can run at the frequency you would like to. Continuous monitoring and enrichment by external data from your email platform is on our radar. So many things are coming!
@saad_el_gueddari Exactly, finding where the problem lives is usually half the work.
Today, MCP is point-in-time per domain, but an agent can loop through multiple sending domains and run checks. Continuous monitoring is the next layer. That’s where we’re going with mailX + MailAdept.
@munis_abbas Oh that sucks! see that’s exactly the kind of deliverability issue we kept seeing over and over.
Everything looks fine, campaigns are sending normally aaand then a chunk of emails quietly starts landing in spam. Glad the timing of mailX resonates :)))
@munis_abbas Here is the best steps to follow: Install our MCP in your Claude account, then ask it what you need to fix. If you need anything more, book a call with @othman_katim
@munis_abbas Exactly the kind of situation we want to make less painful. 15% in spam can quietly kill a newsletter without any obvious warning. Run the domain through mailX and you’ll at least know what to check first.
I've spent the last 15 years in digital marketing, and a big chunk of that running email at scale, at one point sending over 1.5 million emails a day across more than 30 affiliate brands. When you operate at that volume, you learn one lesson fast: deliverability isn't a technical detail. It's the whole game.
Teams usually pour their energy into better copy, sharper targeting, more campaigns, more volume. All of that matters. But none of it counts if the email lands in spam, and the hardest part is that a deliverability problem rarely announces itself. It doesn't throw an error. It just shows up as silence: fewer replies, softer numbers, and no obvious reason why.
That's the problem we built MailX to solve, alongside my co-founders @bengeekly and @thamibenjelloun . We wanted to pull inbox placement out of the black box, help teams see what's actually happening earlier, fix what genuinely moves the needle, and stop guessing. Because sender reputation isn't an afterthought. It's infrastructure.
Excited to launch today and get into it with the PH community 🚀

Oh this is cool - been doing warmups and mx checks manually. Great to see a product that's agent usable. Will give it a spin!
