Best Email Spy Apps Compared

How do Email Spy Apps Work?

Email spy apps work similarly to social media spy apps, and tend to utilize one or all of the following approaches:

• Keylogging: Keylogging essentially logs every button press the target phone makes. This ensures that spying on sent emails is extremely easy.
• In-depth spy approaches: In order to analyze and display received emails and data, the spy tool of your choice must take that data from the phone’s system by posing as a trustworthy app. It then reads the data from the email service app and sends it to you.
• Screenshots: By taking screenshots of the target phone’s screen at regular intervals, email spy apps are capable of providing you with all of the details you need, regardless of the app you want to spy on.

How to Spy on Someone’s Email Messages without Target Phone

We often get the question “How to spy on someone’s Email without having access to their phone?” Unfortunately, there are no easy answers to this question. There are two main ways through which you might be able to do this:

1.  By getting them to follow the installation link for mSpy or an app like it, you can get them to install it without knowing that it’s an app made to spy on them.
2. By having their iCloud credentials, certain email spy tools will be able to show you their email data whenever it gets synced with the cloud.

Are Email Phone Spy Apps Safe?

As with all apps, the short answer is: “It depends.” If you’re downloading free apps that are promising the moon, they’re unlikely to be safe. However, you can easily avoid all of the fake email spy apps by simply choosing any app off of this list, we’ve tested them all out manually and they function on all advertised platforms.

 Free Email Spy Apps

Getting a free download email spy app is tempting to most first-time spy app users. After all, why would you pay for a service you can seemingly get for free? It is true that there are free email spy apps like Mobile Tracker or iKeyMonitor, however, they tend to perform worse than their paid counterparts.

With spy apps, you want to have the most reliability and ease of use you can. Reliability ensures you don’t miss any crucial activities on the target’s device, however, with free apps, you’re risking them going down, or simply not having enough server space for their free users.

Furthermore, all free email spy apps that actually function properly offer a premium version, meaning the free version is a toned-down version of that. They’ll generally have far fewer features, be less reliable, and just overall worse than their paid counterparts.

On the other hand, paid apps like mSpy let you spy on email extremely effectively, all the while maintaining nearly 100% reliability and a superb user interface. Therefore, a free email spy app is best used as an entry point to test the waters before jumping to a better app.
