1. Official Mail App

With iOS 16, Apple has delivered a much-needed feature boost to the official Mail app. You can now unsend an email, schedule one to avoid inconvenient delivery times, and even search for an important email like a pro. The Mail app supports all popular email providers, and you can add a custom email too. Apple allows you to create different folders and flag colors to organize your important emails. Being an official offering from Apple, the Mail app carries all the goodies like multiple widgets, Siri Shortcuts, lock screen widgets, and more.

2. Gmail

Gmail is one of the best Outlook alternatives for iPhone users. Those from the Android camp will find themselves at home with Gmail on the iPhone. Google has carried over the familiar UI from Android to iPhone. Gmail shines with excellent email management with labels, stars, rules (first, you need to set them on the web), and Smart Compose. The latter is Gmail’s killer feature to check suggestions to draft perfect emails on the go. Gmail offers iOS widgets, lock screen widgets, the ability to unsend an email, and a few Siri Shortcuts.

Pros

Familiar UI for Android usersAvailable on Android, iPhone, and webSmart compose is an excellent add-on

Cons

The UI is far from perfectSearch bar is at the top and makes it inconvenient to reach at times

4. Email by Spike

Email by Spike has a unique take on the whole email experience. It turns your boring email inbox into easy-to-use conversations. You might mistake it for another IM (instant messaging) app. It also carries a smarter inbox to organize your receipts, newsletters, spam, orders, and more. Upon adding your email account, Spike will take you to the unconventional Priority home screen with personal email chats with contacts. When you open an email thread (or chat conversation, dare we say), you can draft a reply, attach a picture, GIF, location, or even an audio message.

Pros

5. Yahoo Mail

Although we are long past using Yahoo as the primary email provider, the company still offers a solid email app on iPhone and Android. You can either sign up for a new Yahoo account and link your existing Google or Outlook account with Yahoo to create one. Yahoo Mail’s theming engine is spot on. It allows you to choose from up to 12 colors for the main theme. Yahoo has neatly divided your emails into subscriptions, travel, attachments, and starred categories. The text editor is as feature-rich as you expect from an email app and does the job for most users.

Pros

Lots of themes to customize your experienceNeat organizationAvailable on Android too

Cons

The free version is filled with giant ad bannersCompose button is at the top and can be inconvenient to reach at timesThe UI still needs refinementRequires you to create a Yahoo account

Ditch Outlook on iPhone

No one appreciates ads in an email app. If you no longer plan to upgrade to one of the Microsoft 365 plans to remove Outlook ads, you should check one of the alternatives. Speaking of us, the TechWiser team is divided among Apple Mail, Gmail, and Spark.
