User Reviews (Selected)

• 11/11: “App service fixed, back to 5*.” 11/9: “The app recently stopped working. A web page error appears when opening the app and shows up when viewing incoming/outgoing emails and addresses. App settings also show the same error. The app freezes and must be force closed. The latest update didn’t fix it. Contacted the developer but no response. 1 star now.”
• “Most useless garbage app. You can’t use two mail addresses at once, and you can’t send to more than two users. The rich text system is terrible and pointless. Never works well on a low network.”
• “Nice that InstAddr doesn’t require registration, and you can create unlimited email accounts. If I’m not mistaken, you can also send and receive unlimited emails. InstAddr is among the best email clients and a strong model for what email clients should be. That said, email clients shouldn’t be required for everything.”
