FAQs: Everything You’re Wondering About Cold Email Deliverability & MailKarma’s Infrastructure

What is MailKarma, and how does it compare to other tools?

MailKarma is a dedicated email infrastructure solution built exclusively for cold email outreach. Unlike shared inbox tools or general ESPs, MailKarma gives you complete control over your sending setup—private US IPs, clean domains, and expert-backed deliverability practices. Built by cold email pros, MailKarma is optimized to scale outreach without landing in spam.

How much does cold email infrastructure cost with MailKarma's pricing model? Is there a free trial?

Because MailKarma sets up private infrastructure—including custom domains and mailboxes—it doesn’t offer a traditional free trial. However, you can explore the platform, view your dashboard, and test features before provisioning infrastructure. Our private dedicated email servers cost $150 per server plus $0.001 per email sent, making it extremely cost-effective for high-volume cold email campaigns. For Gmail Workspace solutions, pricing starts at $3.50 per email with a 10-email minimum, dropping to $2.50 per email for volumes over 100 emails. This transparent pricing model ensures you only pay for what you use while maintaining enterprise-grade email deliverability.

Does MailKarma automatically configure DNS records for my domains?

Yes. MailKarma automatically sets up SPF, DKIM, and DMARC records using best-in-class standards. No technical hassle—our system handles everything behind the scenes, and our support team is always ready to assist if needed.

What’s included in my MailKarma subscription?

Every MailKarma subscription includes:

  • Automated DNS setup (SPF, DKIM, DMARC)
  • Private mailbox hosting
  • Ongoing deliverability optimization
  • Server monitoring and uptime guarantees

How many domains and mailboxes do I need?

It depends on your monthly sending volume and the number of contacts per sequence. To simplify this, MailKarma includes a volume-based calculator inside the app to help you choose the optimal setup for scale, safety, and inbox placement.

How is MailKarma different from Gmail or Outlook?

Gmail and Outlook aren't built for cold outreach—they throttle volume, rotate IPs, and limit deliverability. MailKarma gives you:

  • Dedicated infrastructure
  • Warmed IPs and aged domains
  • No shared resources
  • Built-in best practices for cold outreach

It's the infrastructure your outreach actually needs.
