What counts as a free email server hosting tool
Two flavors of free make it onto this page. The first is genuinely free — perpetual, no card required, with usage caps that real teams can fit inside. The second is freemium: a paid product with a free tier that's either time-limited, feature-limited, or capacity-limited. Both have their place, but they fail differently. Free tiers tend to disappear or get throttled when the vendor changes strategy; freemium tiers are usually stable but designed to push you toward upgrade. We label which is which on every card.
The 11 email server hostingtools below are filtered to pricing_model ∈ (free, freemium) and then sorted by community rating and review count — same ranking signal we use everywhere else, just applied to a narrower slice. Every tool here has been used in production by real teams, not just demoed during a Hacker News launch.
Two things to check before committing:the free-tier limits (we list them on each tool's detail page so you know exactly what's included) and the upgrade path. A free tier that hard-caps at 1 GB of storage and 100 monthly active users is different from one that meters by request count or seat. Click through to the tool page to see the full plan table, real pricing for the upgrade tier, and the last community reviews — those usually surface the surprise restrictions vendor docs gloss over.
How we maintain this list
This page refreshes hourly as new ratings, reviews, and pricing changes land in our catalog. The free/freemiumordering is recomputed automatically on every rebuild — we don't freeze rankings or grandfather in providers whose ratings have decayed. Last refreshed: 14 May 2026 (UTC).
Our full ranking methodology, including how we weight ratings vs. review count and how we handle disputed entries, is documented on the methodology page. If you spot a missing provider, an outdated price, or a placement that doesn't match your experience, submit a correction — we read every report and update within 48 hours.
