Verdict

The call

The clearest difference is rating: Spacemail at 4.7 against Polymail's 3.9. Spacemail also leads on monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs fortnightly). Polymail's advantage is iOS requirement (16.0 vs 18.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spacemail holds the better App Store score, 4.7 against 3.9. Both are backed by a comparable volume of ratings — 86 and 369 respectively. Written reviews complicate that: 63% of Polymail's written reviews are positive against 60% of Spacemail's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Polymail ships an update fortnightly, Spacemail every 5 days. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
