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 🚀

What do you blame when your cold emails get no replies?

[mailX by mailwarm (YC S20) @themailX]

A good email strategy means knowing your sender reputation, understanding your authentication setup, monitoring inbox placement, and having a plan when something breaks.

mailX gives you every piece of that puzzle. Tools, experts, training, and community.

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 🙌

[mailX by mailwarm (YC S20) @themailX]

Your emails go to spam. Do you know why? Wednesday, we fix that.

Email deliverability involves sophisticated strategies like sender reputation and engagement metrics to ensure your messages aren't lost in spam. Explore how these elements can elevate your email campaigns.

[mailX by mailwarm (YC S20) @themailX]

Good deliverability starts with understanding how email actually works.

At MailX, we break down complex email infrastructure topics into practical, easy to understand content for modern senders.

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‼️

[mailadept @mailadepthq]

Your emails are failing before content even gets evaluated.

When reverse DNS and the SMTP banner disagree, mailbox providers flag the sender as untrusted. 20–30% of high-volume deliverability issues trace back to this single mismatch.

Domain reputation now matters more than IP reputation.

A new domain hasn’t earned anything. A bad IP can still drag you down.

Every campaign is a test. The filters are taking notes.
