Kamatera is a solid cloud provider particularly well-suited for email marketing infrastructure and burst workloads. Its per-minute billing, 18 global locations, and port 25 availability make it a top choice for email server deployments. For general-purpose hosting, DigitalOcean and Hetzner offer better overall value.
Kamatera Cloud is a cloud provider founded in Israel in 1995 that has evolved from traditional hosting into a modern cloud infrastructure service with 18 global data centers. In 2026, Kamatera occupies a specific niche: it is most popular among email marketers and businesses that need flexible, per-minute-billed cloud servers with port 25 open access — a combination that most mainstream providers cannot match.
Kamatera's standout feature is its per-minute billing model. While most cloud providers bill hourly (and some have moved to per-second billing), Kamatera's per-minute model is genuinely valuable for workloads that run for hours at a time rather than days or months. For email marketing campaigns where you spin up SMTP servers for a 3-hour sending window and then shut them down, paying for exactly 3 hours at per-minute precision is meaningfully cheaper than paying for a full day on an hourly-billed provider.
The 18 global data center locations include US-East (New York, Virginia), US-West (Los Angeles), Canada (Toronto), Netherlands (Amsterdam), Germany (Frankfurt), UK (London), Israel (Petah Tikva), Hong Kong, India (Mumbai), and others. This is a solid footprint that covers most major regions, though it is not as extensive as Vultr's 32 locations. Importantly, Kamatera is one of the few cloud providers that allows port 25 on verified accounts, which is the primary reason email marketers choose it.
Performance is generally competitive for standard compute workloads. Kamatera uses NVMe SSD storage on their cloud instances and their network bandwidth is adequate for most hosting and email use cases. Server provisioning is fast — typically under 60 seconds from order to live instance, which is among the fastest in the industry.
Limitations to be aware of: the control panel UI is functional but less polished than DigitalOcean or Linode; the managed services ecosystem (managed databases, Kubernetes) is less developed than DigitalOcean; and customer support quality is variable compared to the best providers. Kamatera is best used as a specialized tool for email infrastructure rather than a general-purpose cloud platform. Our Kamatera accounts — free trial ($25) and port 25 open ($45) — are among our most popular for email use cases, and the 7-day replacement guarantee covers any issues with port configuration or account access.
