The sophisticated app enables you to create disposable email addresses for free just by activating it.
Your account simultaneously maintains multiple email addresses, which you can utilize for different purposes.
As the service does not have an expiry date, the addresses can be used permanently.

- “There is a website requiring email authentication to sign up, but I don’t want to receive spam messages and newsletters…”
- “Someone I’m not very close asked for my email address…”
- “I need a dedicated contact email address and web form for our event”
- “There are people I’m not that close but want to keep in touch”

The app perfectly caters for all these needs!

The app’s features are as follows:

* You can simultaneously own as many email addresses as you like!
You can create additional email addresses anytime you like in just a second without making any changes to the existing address.
You can either use characters of your choice for the address or have the app to generate short addresses. The app, enhanced with our proprietary technology, is also able to automatically generate easily memorable addresses.

* You can communicate with the address (write new messages, reply, forward, and share)!
You can send out messages from the created address and attach files.
The addresses also support latest features, such as SPF, DKIM (sender authentication), encrypted delivery, etc.

* Push notification is available!
The app notifies the arrival of new messages even when the app is turned off. It can also send out notifications to other smartphones and PCs.
You can turn the push notification off or turn it on only for specified addresses.

* Permanent email addresses!
The addresses you create will function permanently unless you delete them.
Even if you change your mobile or delete the app, the addresses remain intact and can be restored as soon as you sign in!
Although sent and received messages are automatically deleted after a month, you can permanently save them by selecting protection mode for them.

* You can sync with PC and other smartphones!
You can use the same address on PC and other smartphones sync messages.
No difficult setup is required! You only have to sign in with the automatically generated ID and password.

* App supports HTML mails and mail attachments!
The app accepts messages in any formats in any languages. You can also receive emoji and Deco-mails.
You can send and receive mail attachments, while the system blocks malware attachments.

* Perfectly functionable mailer!
You no longer need other email apps, as all functions, e.g. inbox, sent box, filter, mail blocking function, etc. come as a package!
You can open the service as a regular mailer from a browser, etc.

* Full of original features not available in other mailer apps!
You can share messages with friends as a website with a URL, assign email addresses to other people, and create web forms.
More users are using the app to create dedicated contact email address for campaigns and events.

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.

Convenient and Well Designed Application

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!

100% recommended easy 10/10

This app is the best is all I can say, no word to describe this app it’s 100% free and I get to create as many emails as I want, usually it’s a paid service or watch an ad to unlock another email like temp-mail, guess nope on this app you get to create as many emails, weather generated or your own custom email 100% free of ads, purchase a subscription, or annoying banners, it may seem hard to understand but once you get the hang of it, which it took me about a min to understand how it works may seem hard but it’s easy, anyways don’t want to keep sounding like I'm a paid reviewer, but holy this app is so good. Download it rn I recommended to anyone that needs this type of app, as I need many emails for my work place and this app does exactly what I need.
