Email infrastructure for teams that take sending seriously.
SMTP relay, email API, managed PowerMTA, dedicated bare-metal, cold-email infrastructure built for the post-Spamhaus reality, and managed deliverability work done by people instead of dashboards. 23 years from the same Swedish operator. Dedicated IPs in every plan.

Each one is a different shape, because the problems are different.
Most operators sell one product and try to bend it into every use case. We sell six because SMTP relay, transactional API, managed PowerMTA, bare-metal hardware, cold outbound, and deliverability consulting are genuinely different jobs.
SMTP Relay
From €399/mo · 10 dedicated IPs · application-friendlyDrop-in behind any application that already speaks SMTP. The fastest path to dedicated IPs without rewriting how the app sends mail.

The honest comparison. Most of the differences come from a single decision — should dedicated IPs be the default or a paid premium — and that one decision cascades into nearly everything else.

The work most providers don't talk about.
Email infrastructure has gotten harder, not easier. Gmail deployed RETVec inside its spam classifier — 38% better detection, 19.4% fewer false positives, specifically engineered to defeat the adversarial text patterns cold email tools have leaned on for years. Yahoo cut storage from 1TB to 20GB in August 2025, recycling addresses that promptly turned into spamtraps. Spamhaus published a paper in June 2025 stating cold emailing as practised meets their definition of spam.
There is no shortcut around any of this. The work is unglamorous: clean authentication, healthy lists, real engagement, complaint rates below 0.1%, properly aligned DMARC. Stockholm, since 2003 — and we'll still be doing this in 2030.
We made a deliberate choice to stay independent. No private-equity rollup, no rebrand, no flagship investor whose timeline is shorter than our customers'. Same operator team that built this in 2003 is the team running it in 2026.
Three honest entry points, depending on what you actually need.
Not every team needs the same first step. These are the three most common shapes a conversation takes when someone reaches out.
