What is the best webmail app?

The best free webmail service or at least one of the most popular ones is Gmail but there are many other free webmail services in case you want to try something different. So what is the best webmail interface out there? Let’s find out which webmail is the best.

If you are using Microsoft 365 it offers deeper integration with the rest of Microsoft cloud services. If you are planning on using the free version, be prepared to see an ad from time to time. Outlook.com has a wide selection of themes, not as many options as Gmail has but there’s still a variety of themes to choose from.

Conversation view is available and can be turned off or on from the quick settings and if necessary, you can create subfolders under Inbox. Email messages can be categorized and each category can be assigned pre-set color and custom name which will make sorting and navigation easier.

Compose mode provides a lot of formatting options but may seem a bit unintuitive due to the duplicated toolbars. Other than that, it’s solid webmail with all the necessary features you can expect from a professional email service.

Google’s webmail service is well-known and may not need any introduction but for the sake of the comparison, we will go through its best features.
Gmail’s webmail has a wide array of themes, UI customization, and other features like the possibility to link any other account with your Gmail mailbox.
Gmail lets you import emails from your other mailboxes and it has a very efficient spam filter so you will rarely see any spam in your Inbox.

When it comes to folders Gmail has a different approach and instead of the traditional folder structure, you can add a message to multiple folders without actually copying the message itself.
Gmail calls their folders “Labels” so when you label a message it stays in the “All Mail” folder but at the same time it can be viewed under other folders/labels, this helps avoid duplication and keeps mailbox size at bay. Labels created by the user are displayed separately, under the “Labels” section so they are easy to find and manage.

Prominent formatting options in compose mode are nice to have, you can find everything you need in the toolbar including “Confidential mode” which allows you to send expiring messages. Quick access to Google Drive files and the ability to send bigger attachments by uploading them to the cloud storage. If you happen to make a mistake, Gmail has intelligent autocorrect and spell check that will fix it for you.

Apple’s iCloud Mail service offers very basic features without the subscription but its premium features are focused mostly on security and privacy.
Most email features like Mail relay, Hide my email, etc. that help it stand out are locked under the iCloud+ subscription.
Ideal mail cloud service for Apple users as it is possible to create an iCloud mailbox only if you are using one of the Apple devices.

The formatting tools are hidden under a single button and while it provides a clean interface, at first glance it may seem that iCloud Mail is lacking in this department. It’s a pleasant surprise that it is not, all the basics like the font format, indentation, and ability to insert the link are present. Themes are not available in iCloud Mail and as for the conversation view, that isn’t available either so the customization is almost non-existent and there are not much of email-related settings either.

All in all, solid mail service if you need a secure secondary mailbox for your Apple devices but don’t expect much from it aside from displaying, sending, and receiving emails. But if you aren’t an Apple user, no worries, there are plenty of other email services that can get the job done.

Proton Mail

If you are looking for secure webmail with PGP encryption, Proton Mail has you covered. There is even an option to send expiring messages. That may come in handy if you really want to protect some sensitive info.
It is worth noting that with Proton mail you will have to go with the premium plan if you need IMAP access and you want to access the ProtonMail mailbox from 3rd-party email apps. Without the Premium plan, you will be locked out from accessing the mailbox via IMAP so it might become a problem if you decide to switch to another provider.

Minimalistic UI and themes, not as minimalist as iCloud so the features are visible right away(and there are more of them) and it’s quite intuitive if you’re coming from Gmail. Proton Mail supports custom folders and labels so it’s a hybrid of Gmail’s functionality and regular folders but you can’t create custom sub-folders within the existing folder structure.
Proton Mail is using conversation view by default and unlike the competition, you need to go deeper into the settings to disable it.
To sum it up, for productivity-oriented users who prefer extra security and no extra frills in the UI, it is the obvious choice.

Zoho mail offers fewer themes than Gmail but since it is oriented to a similar audience as ProtonMai it’s just an extra feature that is nice to have. There are various services available for companies but the advanced features are locked for free users. While it is paid email service, it offers mail and calendar, web documents, spreadsheets, and a whole lot of work/productivity-oriented features while keeping a minimalistic interface. If you decide to change from Zoho to another email provider they even allow exporting emails in .eml format which can be imported to most email apps.

The interface can be viewed in tabs which makes switching between draft messages, the message list, and other features a very easy task.
The cheapest plan will cover up to 5 mailboxes so it’s ideal for smaller companies with the price of 0,90Eur per month.

Compose window has a well-equipped toolbar, lots of usual formatting options, and a few extras like the ability to edit HTML and record audio messages.

Yahoo screenshot


Free version has ads but can be upgraded to the Pro version, mailbox offers a generous 1TB of space which is much more than the others on this list (The closest in terms of storage are Outlook and Gmail with 15GB of free storage). Themes are available but the selection is limited and the free version appeals more to the casual user.
The free version has a more informal feel overall with colorful themes and semi-integrated Yahoo homepage shortcuts.

All the basic formatting options are available but they are quite limited compared to competitors. Various postcard-like templates can be used for special occasions like holidays and birthdays, again, this feature is more appealing to the casual user.
Quick access to GIFs and emojis has been preferred over more professional features like HTML editor, encryption, or email signatures.

The lack of these features in the compose toolbar solidifies the less-formal mood of the whole Yahoo webmail even more but its storage capacity is hard to beat.

What if you could access all of those services in a secure mail client?

With eM Client you can! You can add all the best web mail services like Gmail, Yahoo, Outlook, Zoho, ProtonMail, and much more, to a single app and access not only webmail but also a calendar, address book, To-Do List, and notes if your email provider has these services.

eM Client allows you to customize its interface to your liking. You can: customize the message list layout, change themes and even create a new theme with the theme editor, edit and create email tags, and add or remove buttons in the toolbars and that’s just a few of the customization options you have access to in eM Client.

Emojis, GIFs, and eM Client stickers can be used for less formal communication so it’s not just a business-oriented tool, you can use it for all of your email needs, personal or professional, eM Client offers a perfect balance between two worlds.

Browsing and managing folders is very easy and to make it even better eM Client can move folders within a single account and between different accounts using drag and drop.
When it comes to reading messages, it is made more convenient with the conversation view that can be turned on or off anytime.

Mailbox size is limited by the size of your disk so if the account mailbox starts getting full you can locally archive your messages and still access them via eM Client. At the same time, server-side storage usage will be reduced. With automatic rules, you can also make this process completely automated.

Why bother yourself with multiple browser tabs and log in to each service separately if you can have a one-stop solution and never look back?

Not convinced? eM Client has a completely free 30-day trial and after the trial, you can purchase a Pro license or stick with the free version. To see what the main differences are, check out the pricing page.
