Open the email app on React Native

I am releasing a book about the React Native ecosystem, which covers everything I wish I had known before I started working with this technology.

If you appreciate my work and would like to show your support, please check the Road to React Native.

In one of my previous articles, I shared how to open an email app with react-native. With another client, I need to execute exactly the same feature. But this time, I am working with a stack-based on expo.

I don't want to send a mail with the Linking API. I just want to launch the mail app and let users read messages. Especially the verification email we just sent during the new account flow.


As a user
I can launch the main email app on my device (iOS or Android)
So that I confirm my email

Pure JavaScript solution

We are going to use 3 differents libraries:

  1. Platform from react-native for specific code
  2. react-native-email-link for iOS
  3. expo-intent-launcher for Android

Setup the libraries

Install the libraries with expo to be sure it's aligned with the version of your expo SDK.


expo install react-native-email-link expo-intent-launcher


const handleOpenEmailboxAsync = async () => {
if (Platform.OS === "ios") {
try {
await openInbox({
message: messageActionSheetiOS,
cancelLabel: "Cancel",
} catch (error) {
console.error(`OpenEmailbox > iOS Error > ${error}`);

if (Platform.OS === "android") {
const activityAction = "android.intent.action.MAIN";
const intentParams: IntentLauncher.IntentLauncherParams = {
category: "android.intent.category.APP_EMAIL",
IntentLauncher.startActivityAsync(activityAction, intentParams);

<Button onPress={handleOpenEmailboxAsync}>Open email app</Button>
  • Works on Android.
  • On iOS you need a real device because there is no on iOS Simulator.
