Mailpool is the infrastructure layer for cold emailโ€”designed to automate domain and inbox setup while maximizing deliverability at scale. It empowers outbound teams, sales agencies, and growth marketers to run high-performing email campaigns without the technical hassle.

With Mailpool, you can bulk-purchase domains, spin up inboxes across Google Workspace, Microsoft 365 Outlook, or custom SMTP providers, and automatically configure critical records like SPF, DKIM, and DMARC. This ensures your emails land in inboxesโ€”not spam foldersโ€”right from day one.

The platform connects seamlessly to any outreach tool via SMTP and IMAP or through native integrations, giving you full flexibility. Whether you're managing 10 inboxes or 1,000, Mailpool makes it easy with bulk creation tools, AI-powered domain recommendations, team management, and real-time deliverability tracking.

Built for scale, Mailpool combines reliability, affordability, and automation into one streamlined solution. Pricing starts at just $3 per inbox per month, making it ideal for outbound teams who need robust, ready-to-use infrastructure without breaking the bankโ€”or dealing with complicated setup.

Questions & Answers

As answered by people managing Mailpool and Klaster.me.

What makes your product unique?

Mailpool's answer

Mailpool stands out by offering fully automated cold email infrastructure with premium deliverability from day one. Unlike traditional setups that require manual domain configuration and complex technical steps, Mailpool handles everythingโ€”bulk domain purchasing, inbox creation (Google, Outlook, SMTP), and deliverability optimizationโ€”so teams can launch and scale outreach instantly without touching DNS records or worrying about spam folders.

Klaster.me's answer:

Klaster is not a course or a content library โ€” it is a practice platform for high-stakes communication. Instead of teaching theory, Klaster lets users rehearse real conversations (sales calls, negotiations, presentations, interviews) under realistic constraints and receive immediate AI feedback on clarity, pace, and delivery.

Its combination of AI-powered simulation, real-world scenarios, and measurable progress tracking makes communication practice repeatable, scalable, and consistent โ€” something traditional training and most apps fail to deliver.

Why should a person choose your product over its competitors?

Klaster.me's answer:

Most communication tools focus on what to say. Klaster focuses on how you perform when it matters.

Users choose Klaster because it allows them to: - Practice real scenarios instead of watching lessons - Get instant, objective feedback instead of subjective opinions - Improve consistency across teams, not just top performers - Train safely before high-pressure moments happen

Klaster bridges the gap between knowing and doing โ€” which is where most communication tools stop.

How would you describe the primary audience of your product?

Klaster.me's answer:

Klaster is built for professionals who communicate for a living, including: - Sales and GTM teams - Founders and leaders - Consultants and client-facing professionals - Individuals preparing for high-stakes meetings, presentations, or negotiations

It is especially valuable for teams that want to scale performance without relying on โ€œhero reps.โ€

What's the story behind your product?

Klaster.me's answer:

Klaster was founded by Leyla Baymaganbetova, a second-time founder with a prior exit and years of experience working with consultants, sales teams, and leaders in high-pressure environments.

Through this work, one pattern became clear: revenue is rarely lost due to strategy or pricing โ€” itโ€™s lost when critical conversations are handled inconsistently.

Klaster was created to solve that problem by giving teams a way to pressure-test real conversations before they happen, turning top-performer behavior into something repeatable at scale.

Which are the primary technologies used for building your product?

Klaster.me's answer:

Klaster is built using: - AI-driven speech analysis for real-time feedback on pace, clarity, and filler words - Natural language processing to simulate realistic conversations - Cloud-based infrastructure for scalability and cross-device access - Data-driven progress tracking to measure improvement over time

The technology is designed to support short, repeatable practice โ€” not passive learning.

Who are some of the biggest customers of your product?

Klaster.me's answer:

Klaster works with: - Sales and leadership teams across B2B organizations - Professionals from consulting, real estate, and high-stakes sales environments - Individuals and teams trained previously at MBB and Big 4 consulting firms

Many customers engage with Klaster as both an individual practice tool and a team performance platform, using it to standardize communication quality across their organizations.
