Bravo @bengeekly@thamibenjelloun@amraniyasser!!! Is mailX for a more beginner audience while Mailwarm is more for advanced/expert audience or are they complementary?
@thamibenjelloun@amraniyasser@basmainparis MailX and Mailwarm are complementary. MailX is Free, with no sign up and help you set the technical part, we made it AI agent ready so it's easy for anyone to setup. Mailwarm is to warm up your inbox after, so your emails actually land in inbox and not spam. So you can see MailX as the first step (setup right your SPF, DKIM, DMARC...) and Mailwarm as the second step (build the reputation of your inbox so it's trusted). Both tools work for everyone, beginner or expert, just different jobs 🙏
@basmainparis Thank you! They’re definitely more complementary than overlapping.
Mailwarm focuses on email warmup and sender reputation, while mailX is more about diagnosing, understanding, and fixing deliverability issues across the whole setup.
There’s also a usability difference: mailX is designed to make deliverability much more accessible to non-experts and AI agents, while still being useful for more advanced senders too.
@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 All three. Cold email, newsletters, and transactional emails all rely on the same core layer: setup, authentication, reputation, and infrastructure.

Email outreach is our core growth channel at Elvixs. One broken SPF record and your whole campaign is dead in spam silently. The diagnosis-first approach is exactly what was missing. Congrats on the launch 🚀
@rajanmishraaa That’s one of the scariest parts of deliverability things can break very quietly.
A single SPF or DMARC issue can tank an entire campaign while everything still seems normal from the sending side. That's a huge part of why we built mailX in the first place. And thank you I appreciate that :))
@rajanmishraaa Thanks! 'Dead in spam silently' is exactly the failure mode that kills campaigns for months while teams keep blaming the copy and rewriting subject lines. Glad the diagnosis-first framing lands.
@rajanmishraaa Oh woow, feel free to use Mailx and give us your feedback

Congrats on shipping! 🚀
The "usable by AI agents" part stood out to me; most deliverability tools assume a human reading a dashboard. Are you exposing this as an MCP server / API that an outreach agent could call before every send, or is it more of a one-shot audit? Curious how you see agents using it in practice.
@natalia_zak Thank you!! and yes, the idea is much closer to an MCP/API workflow than a simple one shot audit.
We think agents should be able to check domain health, authentication, reputation signals, and deliverability risk continuously ideally before and during sending, not only after something breaks.
A big part of the vision is making deliverability understandable and actionable for agents, not just humans reading dashboards.
@natalia_zak Exactly. We expose it through both MCP and API. The first use case is: agent checks before sending or scaling, domain setup, auth, blacklists, risks, then says “safe to send” or “fix this first.” Today it’s mostly diagnostic. The direction is continuous checks inside outreach workflows, not just one-shot audits.

the AI agent compatibility angle is interesting. Feels like more developer tools are starting to prepare for autonomous workflows now.
@robert_hughes5 For sure, I think a lot of infrastructure and developer tools will need to become more agent-friendly over time, not just human-dashboard-friendly.
@robert_hughes5 Exactly. Agents will need tools they can actually call, not just dashboards humans read. That’s the shift we’re building for with API + MCP.
@robert_hughes5 Exactly. It feels like the shift now is from “AI-assisted tools” to tools that are built assuming agents will actively interact with them.
@robert_hughes5 100% if your outreach is AI agent made, your deliverability should too

Email is one of the most effective and frustrating marketing channels for the products. But if you are on Google Workspace, doesn't it handle this process?
@vivekn4u Google Workspace definitely helps, but it doesn’t fully solve deliverability automatically.
You still have DNS/authentication configuration, domain reputation, sending behavior, spam filtering, forwarding setups, third-party tools, etc. And when something breaks, the debugging process can get messy
@vivekn4u Common misconception. Workspace gets your email out the door. Where it lands is a different problem.
A few things Workspace doesn't do for you. SPF and DMARC have to be configured in your DNS. DKIM needs to be enabled in admin and the matching key published in DNS, otherwise your sending domain isn't even signed by you.
Sending reputation is built over time based on engagement, and Workspace doesn't manage that for you. Cold outbound to people who didn't ask for it actively hurts that reputation, regardless of who hosts the inbox. And there's no visibility from inside Workspace into whether your emails land in primary, promotions, or spam.
That last one is where most teams find out their cold campaigns were quietly going to spam for months.

@othman_katim Thank you for the detailed explanation.
@vivekn4u If you are using Gmail.com Google is handling everything. If you are using your own domain with Google Workspace, Google let you manage your DNS setting, while giving you general recommendation. In this case make sure to ask your AI agent with MailX to double check it
@vivekn4u Google Workspace gives you the sending infrastructure, but it doesn’t guarantee inbox placement. You still need clean authentication, reputation, sending behavior, and monitoring.
@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.

mailX helps you diagnose what’s wrong and what to fix.
Mailwarm helps you build sender reputation and improve inbox placement over time.
Simple way to see it: mailX tells you the problem, Mailwarm helps you improve the reputation layer.
Is mailX mainly built for cold email, or can it also help newsletters and transactional emails?
