mailX by mailwarm - Email deliverability toolkit for humans and AI agents

@andrzej_zarod good question. If you only send a small number of important emails like investor outreach, sales conversations, partnerships, support replies, etc missing the inbox hits harder. Higher volume makes the patterns more visible, but the underlying problems affect everyone.

@andrzej_zarod Low-volume are definitely benefiting setting DNS properly should be done by everyone. It's the highest results for the lowest effort/cost (Free)

@andrzej_zarod Yes, useful even at low volume. Actually, it’s better to catch deliverability issues before scaling.

At high volume, the pain is bigger. At low volume, mailX helps you avoid damaging the domain early. It the first step before starting email warmup.

@andrzej_zarod Absolutely! While high-volume senders get their Google Postmaster and Yahoo Sender Hub dashboards to populate faster, correcting your DNS protocols at a lower volume is highly strategic. It accelerates your long-term reputation growth. Establishing a healthy sender score from day one is far easier than trying to repair a damaged reputation at high volume, even if the tracking data takes a bit longer to catch up initially.

@andrzej_zarod Honestly, its for both but in different ways.

At higher volume, deliverability problems become expensive very quickly. But for low-volume founders, even a few important emails landing in spam can hurt sales, partnerships, or fundraising, so having the basics configured properly still matters a lot.

@campritchard mailX is not something we built because “AI agents” are trending. It comes from years of seeing the same email deliverability pain inside real teams. The goal was to turn that experience into something simple, fast, and usable by both humans and agents.

@campritchard Thank you to trust our team. We learned and keep learning many things about deliverability. Our experience with Mailwarm thought us a lot about how to build mailX

@mansuiki Thank you! 🙏 That’s exactly the frustration we kept hearing from users.

Most of the time, the issue isn’t impossible to fix it’s hard to pin point what's actually wrong in the first place.

We wanted to make that process much clearer and less intimidating :))

@mansuiki AI become so good at debugging, that it seemed obvious Agent should be the ones that fix all email protocols.

@mansuiki You’re absolutely right, email is one of those things that looks simple on the surface but gets painful fast when deliverability breaks and you’re left guessing what went wrong. That’s exactly the gap we’re trying to close: making the “invisible” issues visible and actionable instead of relying on trial and error.

@mansuiki Thanks! That's the exact gap. Most tools barely surface that something's wrong without telling you which layer broke or what specific record to fix, which is where most teams stall out for weeks. MailX hands you the fix.

@mansuiki Thank you 🙏

The hardest part is often not fixing the issue, it’s finding where the issue actually lives. That’s what we want to make faster with mailX: clear diagnosis, then clear next steps.

@dan_tiptap Our MCP will Flag problems and give back recommendation to you agent for fixing. If your agent have access to his DNS he probably can fix it. But I would recommend to double check as DNS is a sensitive topic.

@dan_tiptap Today it flags and explains issues through MCP. Auto-fix is the next step, but with human approval. We don’t want agents changing DNS blindly.

Goal: agent detects, prepares the fix, human validates.

@dan_tiptap Thank you! Right now it’s more focused on diagnosis, monitoring, and structured remediation guidance rather than blindly auto-fixing things.

The goal is for agents to understand what’s wrong, why it matters, and what actions to take next while still keeping humans in control for sensitive configuration changes.

@eduardnpetrache MailX doesn't discriminate :) Cold email tends to make deliverability pain more visible, but the same underlying issues affect marketing newsletters, transactional emails, onboarding emails, etc.

At the end of the day, inbox providers care about trust, authentication, reputation, and behavior regardless of the email category and that's where MailX comes in ;)

@eduardnpetrache MailX is both cold email, newsletter and transactional emails

@eduardnpetrache All three. Cold email, newsletters, and transactional emails all rely on the same core layer: setup, authentication, reputation, and infrastructure.

@pranavprakash Thanks a bunch. Hey it's never too late to give a go :))

@pranavprakash You can still benefit, your DMARC is set to none, and it would be beneficial to fix it: https://themailx.com/report/a1d343a2-b6d6-447c-8346-2105937dadf1

@pranavprakash Thank you so much 🙏

That’s exactly why we built it. Email Deliverability is one of those problems you often discover too late. Really appreciate the support!

@pranavprakash Thank you !!

@pranavprakash Really appreciate this, thank you 🙏

A lot of the product came from seeing how painful and confusing deliverability setup still is for founders and small teams, so comments like this mean a lot.

@nitiksh_gaba It's probably easier to understand because you will be chatting with your agent, so if you don't understand anything, you can just ask it and the AI will answer

@nitiksh_gaba Yes, that’s the point. Founders don’t need more raw technical data. They need to know what’s broken, why it matters, and what to fix first. mailX turns the technical layer into clear answers and concrete next steps.

@nitiksh_gaba That’s exactly the goal. Most founders don’t want to spend hours digging through DNS records or trying to understand why emails land in spam.

We try to surface the important issues clearly, explain what’s wrong in plain English, and make the audit process much faster.

@dmitry_zakharov_ai Thanks

@imad_elkhafi It works for all three: cold outreach, marketing, and transactional emails.

For new domains, mailX helps you check the foundation first: DNS, authentication, blacklist risk, setup. But no tool makes a fresh domain instantly trusted. You still need gradual sending, clean lists, and consistent positive behavior.

@imad_elkhafi It works for all three: cold outreach, transactional, and marketing. The infrastructure checks are the same regardless. For new domains it will give you step by step what to handle, then you should still warmup your domain. You can use Mailwarm for that
