"Like most founders, email has been our #1 sales channel since our first startup in Paris.That’s what led us to build mailwarm and 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.If email is part of your growth, tell me in the comments how you’re using it. We’ll take a look and help you improve your inbox placement."

"Nice launch! Warm-up tools vary a lot in reliability these days. What makes your warming algorithm stand out from other similar services? And do you offer custom schedules for different sending volumes? Also, what’s your single most sticky, must-have feature—the one that makes enterprises choose you and hard to leave, given all their procurement tradeoffs?"

"Real problem! are you launching with a CLI or similar so that we can manage this from our setups in Codex or CC?"

"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."

"congratulations on the launch 🎉"

"about the arms race dynamic here. inbox providers are actively working to identify and discount warmup traffic and the tools in this space have to constantly evolve to stay ahead. what does Mailwarm's approach look like in 2026 compared to what it was doing two years ago and how much of the original warmup mechanism is still working versus what's been rebuilt to avoid detection"
GMA Community
"Since warming up a domain takes time, what specific metrics or dashboard insights does Mailwarm provide to help users know the exact moment their domain is fully 'warmed up' and ready for a full-scale cold outreach campaign?"
GMA Community
"How can users separate real-world deliverability lift from your own network's engagement in the dashboard?""
GMA Community
"Congrats on the 2.0 launch. Deliverability is such a headache lately with all the provider updates. Quick question, does this help if a domain is already totally tanked and hitting the spam folder, or is it mostly for keeping healthy domains warm? Also, what about brand new domains? thanks!"
GMA Community
"If Gmail can fingerprint your seed network, doesn't sustained warm-up traffic itself become a negative signal? How do you keep the network from getting flagged wholesale?"
GMA Community
"just checked this out. curious, what's been harder so far: building the product or getting people to discover it?"
GMA Community
"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."
GMA Community
"How much time we need to wait for warm up to complete before starting email campaign. Is this fully automated?"
GMA Community
"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."
GMA Community
"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"

"Congrats @thamibenjelloun ! Much needed."

"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."
