Hey Product Hunt community 👋
I spent 8 years in roles where I was sending endless follow-up emails, onboarding messages, CRM emails, and customer reminders.
I even worked at a CRM SaaS where I would help users with email-related issues without fully understanding what was happening behind the scenes. Whenever an email disappeared, the advice was often: “Can you check your spam folder?” or “Maybe it’s a DNS issue?”
Working on Mailwarm made me realize how much is actually happening before an email reaches the inbox.
I learned that hitting “send” is only the visible part. Behind every email, there is sender reputation, engagement, domain setup, sending behavior, inbox placement, and a lot of small signals that can decide whether your email lands in the inbox or not.
We wanted to help teams warm up their inboxes properly, build better sender reputation, monitor what’s happening, and get real guidance when something starts going wrong.
Because most founders, sales teams, and marketers don’t want to become deliverability experts. They just want their emails to reach the inbox and know what to fix when they don’t.
The team and I are live today, happy to answer your questions and hear how you’re handling deliverability 🚀

Hi Product Hunt 👋
Mailwarm 2.0 was interesting because email deliverability looks simple from the outside, but technically there are a lot of moving parts behind it.
Warmup activity, inbox interactions, sending behavior, domain setup, reputation signals, monitoring… everything needs to work together if you want the system to be useful and reliable.
From a dev perspective, the challenge was not just to automate email warmup, but to make the whole process easier to track, understand, and act on.
A lot of deliverability problems are invisible until performance starts dropping, so we focused on building something that helps teams see issues earlier and avoid guessing.
Excited to launch Mailwarm today and hear what people think.
Congrats on the launch team 🚀 6 years in and still shipping is the hard part.
Quick notes from the cold outreach trenches: per-ESP reputation monitoring is the right call, Gmail, Outlook and Yahoo weight things so differently that one blended spam score always hid where the real leak was. The non-linear ramp curves are also smart; mechanical warmup signatures are exactly what ESPs got good at catching.
Rooting for the relaunch 👏

@saad_el_gueddari Wow, thanks so much! Longevity in this space is hard, but it’s operators like you who keep us pushing to build better tools.
It’s incredibly validating to hear you call out the non-linear curves and per-ESP monitoring. The team spent so much time refining the engine to dodge those mechanical warmup signatures you mentioned, because Google and Microsoft have gotten terrifyingly smart at catching basic automation.
Thanks for the launch day support :))

Hi Product Hunt Community!
I’m Naim, and I handle the technical account management side of things at Mailwarm. If there’s one thing I’ve learned the hard way, it’s this: when your emails start hitting spam, it’s almost never for just one reason.
It’s a ghost in the machine. Maybe a DNS record is slightly off. Maybe a sudden spike in sending volume triggered a filter. Or worse ... your domain reputation has been quietly tanking for weeks, and you only notice when your reply rates hit zero. It is incredibly painful to waste days tweaking random settings in the dark, hoping something works.
That frustration right there is why Mailwarm was built.
The goal is to turn the black box of email deliverability into a transparent dashboard. Mailwarm helps you safely warm up your sender reputation, track the right technical signals, spot infrastructure issues early, and understand exactly what needs attention.
Cold outreach and email marketing are still unmatched growth channels but only if your audience actually sees what you send...
We are back with Mailwarm 2.0 🤘🏻! We’d love your support, your feedback, and for any email questions just drop them in the comments below :))

@abhishekr_ai Great to have an existing user in the thread! You are going to notice a massive difference with 2.0. Can't wait for you to try it out. Let us know your thoughts once you dive in :))
Mailwarm 2.0 looks great, and the "basic warmup isn't enough anymore" line hit home. Quick one for you: I'm doing all my own outreach to investors and design partners from a domain that's barely a month old, pretty low volume. How do you think about warming a fresh domain while still sending real outreach, without getting buried in spam by Gmail and Outlook those first few weeks? And what's the tell that the domain is finally good to push more sends? Would take you up on that deliverability audit if the offer's still open.
