일회용 이메일 주소 (InstAddr‪)‬ 4+

This app outshines every other “disposable” or “temp” email address generator in the App Store. The fact you can easily and instantly generate not just a disposable address but essentially a fully functional email account which can receive as well as SEND emails, & the addresses are PERMANENT- (this is super important for signing up for services or accounts on websites such as in the online retail sector that are lacking in privacy and prone to spamming you with advertising, but which you want to be able to log in to indefinitely, or for making ANY account that requires an email address which you don’t necessarily trust with your more personal email accounts.). Has a huge breadth of customization options, and a year of premium is only $7.99- compare that to $60+ for similar apps with less flexibility in features; With premium you get far more server/domain name options for creating fully featured email accounts, AND it (optionally) integrates with the native iOS and Mac Mail PoP3 and SMTP protocols, allowing you to check the inbox, outbox, and compose and send emails from any generated address, now conveniently listed with all your other addresses in the native Mail App. This app is a must-have for anyone using the Internet in 2021, period.

I downloaded this app out of curiosity as it showed up as one of my recommendations when browsing through the app store. I didn’t expect to still be using it today and was incredibly surprised at how intuitive and professionally designed the interface was. This app is jam packed with features. You can have the app generate a random email address for you or you can create custom addresses and choose from a continuously updated list of unique domain names. You’re also given the option to choose whether or not you want a permanent address or one that has an expiration date. On top of all that, all these options can be utilized with one click from a quick action table located on the home screen. There are more features, most of which I’m still discovering over time. You have the option to automatically forward mail from a specific inbox and each address includes its own POP/IMAP configuration in case you’d rather manage emails from a third party client. Such a wonderful app that’s saved me so much time, the devs are genius! Highly recommended!

PROSOI cannot tell you how much I have used this app (and website/chrome extension)!
I HIGHLY recommend it to anybody who needs emails on the fly. I have the Chrome extension on my iMac and the app on my iPhone. It's one of the first apps downloaded on my new devices. I seriously can't say enough good about these guys.

The bad:
I had an experience in 2020 in which my device was stolen and I didn't have the password memorized which I thought was no problem because the app said you could log in if you were in a place you had previously logged in (my house for instance) well they didn't actually have a feature that could allow for that and the support was very apprehensive and denied my request completely and I ended up losing A LOT of information and money because of it.
