ReceptionRating · Positive reviews · Number of ratings

Contact Groups holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Contact Groups has 4.2K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 71% of iMailG's written reviews are positive against 49% of Contact Groups's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iMailG ships an update every 3 months, Contact Groups every 2 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
