How We Improve Your Deliverability
Unlike popular email tools (for example Gmail or Outlook), MailKarma was specifically built for cold outreach. Our features will directly improve your deliverability and protect your sender reputation.
Dedicated IP
With Mailkarma you get your own dedicated server to send emails from. That means you alone have full control over the deliverability - there’s no chance of anyone else decreasing the server’s reputation.
Multi IP Provisioning
You not only have your dedicated IP with MailKarma, but you can also purchase additional IPs to further protect your reputation and act fast, whenever you notice any deliverability issues.
Dedicated IP
When setting up with Mailkarma, we will take care of your DNS settings to make sure they are set up using the best practices and optimized for email deliverability.
Multi IP Provisioning

FAQs: Everything You’re Wondering About Cold Email Deliverability & MailKarma’s Infrastructure
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.
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.
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.
Every MailKarma subscription includes:
- Automated DNS setup (SPF, DKIM, DMARC)
- Private mailbox hosting
- Ongoing deliverability optimization
- Server monitoring and uptime guarantees
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.
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.
