Free Email Clients Apps iPhone, iPad- Free Mail Apps Alternatives
#1: Spark Mail App 
Spark is a brilliant app specially designed to sort multiple accounts with the most innovative techniques.
It features advanced tools for user-friendliness and sorts incoming emails into three categories: Newsletters, Personal, and Notifications.
With its smart features, you can schedule emails to send later, and if you’re waiting for an important reply, set a reminder for it. You can also search and get emails quickly, and you can find emails by searching attachment names. All these searches will be saved.
Even when the Spark app is not launched, you can send emails directly from the lock screen for quick replies.
Spark allows you to customize your front page with a variety of themes, such as Black, Light Blue, Dark Sky, and Dark Blue.
#2: Edison Mail

Edison reflects its assistant features along with some standard features on Spark.
Assistant doesn’t mean that it will automatically write an email for you. It has some features that can ease the management of emails, which is why it has been given the title of Assistant.
If you have subscribed to a newsletter, product, or organization to receive an email from them, Edison can unsubscribe with just a one-touch operation.
You can snooze essential emails so you will never forget to read them, and sadly, it doesn’t allow you to make a VIP list and schedule emails like Spark.
The developers have designed the app’s UI so that if you have a brand new iPhone, it will cover the whole screen, and you will love it.
View your emails directly from the widget of Edison, and as usual, you will get notifications too.
#3: Outlook – Secure Email, Calendar & Files in one place

It doesn’t mean that Outlook is Microsoft’s product, so it will not work with iOS. Instead, it works great with an iPhone.
It intelligently manages and sorts all of your inboxes of different accounts, and you will get a special Focused inbox that is specially included for important emails. Be focused only on essential emails by enabling the snooze function.
Multiple gestures for quick results, like swiping right to schedule mail, swiping left to archive, and more. Outlook’s smart tech only shows important correspondence on the lock screen and avoids junk emails.
Maintain your privacy with Outlook, without your Touch ID, no one can read your emails once you activate that lock.
The calendar is synced with this client to keep you updated about events.
