Most founders rely on email to grow, but emails don’t land in the inbox by magic. Mailwarm 2.0 is the premium email warmup and deliverability system built to give your emails the best chance of reaching the inbox. It combines automated warmup, real engagement, monitoring, infrastructure checks, and experts call available for every subscriber.
Like most founders, email has been our #1 sales channel since our first startup in Paris.
That’s what led us to build mailwarmand work on email deliverability since 2020.
And one thing became clear very early: your emails don’t land in the inbox by magic.
Back in 2020, we launched Mailwarm here on Product Hunt as one of the first email warmup tools. It became #1 Product of the Day 🏆 and since then, we’ve helped 10,000+ founders, sales teams, agencies, and businesses improve sender reputation and avoid the spam folder.
But over the years, we learned something important: Basic warmup is not enough anymore.
Teams need real engagement signals, monitoring, infrastructure checks, and sometimes a real deliverability expert to understand what’s happening and what to fix.
That’s why we built Mailwarm 2.0.
Not just the original email warmup tool. A premium email warmup and deliverability system built to give your emails the best chance of reaching the inbox.

just checked this out.
curious, what's been harder so far: building the product or getting people to discover it?
Just curious about how long it typically takes to see a noticeable improvement in deliverability? Asking because most cold outreach tools promise inbox placement, but the warm-up window is where campaigns usually stall.
How much time we need to wait for warm up to complete before starting email campaign. Is this fully automated?
We use a similar service. How many warm-up accounts do you have, and how often are they rotated? Because if, for example, the warm-up is done using the same 100 mailboxes over and over, it will lose its effectiveness after a month.
Congrats on the relaunch! it's bold move going paid-only with no free tier. That makes the first week after payment the real moment of truth. Do you know which early signal makes people stay vs leave or ask for a refund: first email pulled out of spam, the reputation graph ticking up, or something else? Curious how sharply you can see that point, like aha-moment
the entire landing page and website look absolutely well-prep and psychologically made!! it actually hits my pain point of restarting the warm up circle for every new SaaS launch.
congrats Thami and Othman!!!
Mailwarm 2.0 sounds interesting. We rely heavily on email for growth, and anything that gives real deliverability insights is worth checking out
Love seeing tools built by founders who use email as their main channel. Curious how Mailwarm 2.0 handles different ESPs—always a challenge keeping everything consistent across platforms.
Congrats on the launch! As someone in the email industry, I know how tricky inbox placement can be. Excited to see a tool that goes beyond simple warmup and actually monitors engagement.
I am currently using warmy for the purpose and the only difference i see is real-time inbox placement tracker Whats your USP ?
Curious how you decide when warmup should taper off vs stay steady—especially for teams whose real sending volume spikes. Any heuristics you recommend for keeping signals “natural” at scale?
Strong launch guys!
Would recommend provisioning email for agent and warming it up for outbound as a feature request :)
This looks promising. I am going to start cold emails and this looks worth checking out. All the best @thamibenjelloun
Cold email works best and will be always their. A dedicated warup tool like mailwarm is a must needed one. Looking forward to using it. Congrats on the launch ( :
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 👏
Inbox placement is one of those things people only think about when it suddenly stops working 😄 Love the focus on deliverability beyond basic warmup. Congrats!
