Mailwarm 2.0 - The email warmup tool, upgraded for deliverability.

@volodymyr_kreschenko It absolutely is. If email drives your growth, flying blind on deliverability is like running a sales team with the headlights turned off. You think you're moving fast, but you have no real visibility into what is actually making it to your prospects.

With the strict filtering rules major inbox providers have enforced recently, old-school "bot-driven" warmup tools just don't cut it anymore. Mailwarm 2.0 caught a lot of traction because it shifts the focus from vanity activity metrics to live, actionable placement data.

The Real Upgrades in 2.0:

• Live 24/7 Placement Testing: It shows you exactly where your emails are landing (Inbox vs. Spam) across Gmail, Outlook, and Yahoo in real time, rather than giving you a delayed guess.

• Human-Mimicking Network: It taps into a network of 50,000+ real, aged inboxes to simulate genuine human behavior (opening, marking as important, replying with realistic threads) which satisfies modern, AI-driven spam filters.

• Infrastructure Auditing: It constantly monitors your SPF, DKIM, and DMARC health alongside major blacklists so a technical glitch doesn't quietly tank an entire outreach sequence.

When email is your primary growth engine, even a minor dip in sender reputation can quietly trigger a massive revenue leak.

What is the biggest deliverability blind spot or specific friction point you are running into with your campaigns right now?

@olamius23 Definitely getting people to discover it 😅 Building is hard, but at least you know what needs to be done. Distribution is a completely different challenge.

That said, launches like Product Hunt are a great opportunity to get in front of people who actually care about the problem you're solving 🙌

@nurlyzhann I would not define “fully warmed up” as one fixed moment. It depends on your domain age, history, provider, current reputation, and target volume.

In Mailwarm, the signals to watch are mainly spam score, inbox placement, positive interactions, provider-level performance, and reputation trend over time. The goal is not just “warmup completed.”
The goal is: are the signals stable enough to start increasing volume safely?

Are you preparing a brand-new domain or trying to scale an existing one?

@inderpreet_singh1 Thank you for your support :))

@jalcantara Hello Jorge,

Right now we're focused on making the core experience as simple as possible through the web app. That said, we can see a lot of value in a CLI and API for developers who want to manage warmups, monitor deliverability, and automate workflows directly from tools like Codex, Claude Code, CI/CD pipelines, or their own internal systems.

@lizzy_leeeee Thank you!

What makes us different is that we've been focused on deliverability for years, so the warmup isn't just about generating activity, it's about building and maintaining sender reputation in a way that reflects real-world sending behavior.

And yes, users can adapt warmup settings based on their goals and sending volumes.

As for the most valuable feature, I'd say it's trust and reliability. Deliverability directly impacts revenue, so teams want a solution they can depend on long term rather than constantly switching tools and risking their sender reputation.

@krishna_gupta51 Hello Krishna, The spam percentage is based on inbox placement tests rather than a prediction model.
