Hello everyone, we’re live on Product Hunt today! 🚀

After months of building, improving, testing, and obsessing over deliverability, Mailwarm 2.0 is officially here.

Mailwarm helps businesses improve email deliverability and gives every email the best possible chance of landing in the inbox, and not the spam folder.

Whether you're running cold outreach, sales campaigns, newsletters, or customer emails, deliverability matters more than ever. We built Mailwarm to make that process simpler, smarter, and more reliable.

Huge shoutout to everyone in the team who helped shape this launch ❤️

We’d genuinely love your support and feedback today 👇

In 2020, I wasn’t part of the @mailwarm founding team.

But I already knew this product had something special: Helping emails reach the inbox, not spam.

Years later, with @BenGeekly and @OthmanKatim, we upgraded it.

Mailwarm 2.0 is live 🚀

Launching tomorrow on @ProductHunt 🚀

Founders get pitched all day in their DMs, on LinkedIn, through mutual intros or even in their inbox.

But here is something most X jobbers do not realize, a cold email that lands in primary inbox actually stands out more than a DM right now.

DMs are noisy because everyone is doing it. But a clean, personalized email from a warm inbox? Will get read.

The secret is not writing a better message. It is making sure the message arrives.

That is what mailwarm does. It warms your inbox, ensures better placement and gets you more replies📩

[Mailwarm @mailwarm]

It is frustrating as a founder when after building your product, closing your first few deals, and finally being ready to scale, you realize half your emails are landing in spam instead of inboxes.

Scaling outreach should not mean babysitting your inbox. Mailwarm runs in the background warming up your domain so every email you send actually gets seen. You focus on building. We handle the deliverability 📩

Let me do some quick math for the agency owners in here.

You are paying for leads. Maybe $0.10 to $0.50 per contact depending on your source. You load up 500 leads into a campaign. That is $50 to $250 in lead costs alone.

If 60% of your emails land in spam because your inbox is not warmed up, you just threw away $30 to $150 worth of leads. On a single campaign.

Multiply that across a month. Across multiple clients.

Warming up your inboxes costs a fraction of what you are losing by skipping it.

Every. Single. Time.

Almost 20 years ago 🥸, I started building things before knowing the word “startup”.

One lesson stayed:
Growth is full of invisible blockers.

For us, one was email deliverability.

That’s why we built @themailX

Launching Wednesday on @ProductHunt 🙌

[Mailwarm @mailwarm]

@ThamiBenjelloun @themailX @ProductHunt We have already finished 1st product of the day @ProductHunt 5 years ago and we are ready to do the same for @themailX 🥇

[Mailwarm @mailwarm]

Spot the difference. I will wait.

[Mailwarm @mailwarm]

Mailwarm has helped over 35,000 inboxes build trust because cold outreach is only as good as your deliverability.

We offer real engagement and warmups. If your emails still hit spam, you haven’t tried mailwarm.

Warm up your domain now!!

[Mailwarm @mailwarm]

Warmup isn't optional anymore.

Gmail and Yahoo's 2024 rules require consistent sending behavior from day one. Skip warmup and you're starting at a reputation disadvantage you can't recover from.

Automated warmup builds the track record you need, and at mailwarm, we guarantee that‼️
https://t.co/zyvsFyNSQa

[Mailwarm @mailwarm]

Your sender reputation doesn't care how hard you're working.

It cares about real engagement signals: opens, replies, inbox movements. Automated warmup generates those at scale. Manual warmup can't.

That's the difference between reputation that holds and reputation that burns.
https://t.co/zyvsFyNSQa

[Mailwarm @mailwarm]

Your email infrastructure is deciding deliverability before your copy ever does.

Gmail checks sender reputation, authentication, and sending patterns first. Subject lines and body content get evaluated last.

Build reputation through warmup. Everything else follows.

[Mailwarm @mailwarm]

You don’t need a new Gmail account for every signup.

Use Gmail aliases instead.

Mailwarm’s free Gmail Generator helps you create plus aliases and dot variations you can use for newsletters, shopping, trials, and filters.

Email providers check multiple blacklists in real time📤.

If your domain or IP is listed, your emails can be filtered, delayed, or rejected entirely, and most people don’t check this early enough.

Run a quick check with Mailwarm’s free blacklist tool and catch issues before they damage your deliverability.
