The internet has impacted the way we communicate to an extent that most of our communication happens on smartphones through apps like WhatsApp, Telegram, and Signal, or via social media. However, even in this era, email still stands to be one of the primary modes of communication. A lot of information and details, (mostly formal and even confidential) are shared over email.

The standard email service providers like Gmail, Yahoo Mail, Outlook, iCloud Mail, and others are some of the most popular email services that are used by individuals all around the globe. Although these providers offer their services for free, there is a hidden cost that some of the users might not mind, but it can be a concern for others.

  • Dedicated apps for email service: Many email services provide dedicated apps for emails that make it more convenient to access your emails and other related services. So, you should always look for those who provide a dedicated app, instead of the traditional integrated email service.
  • Privacy policies: Privacy policies are vital as they tell how your data will be managed, stored, and protected and what other security standards will be utilized. This will let you know the transparency and the procedures used by the email service provider concerning user data.
  • Essential features and tools: Apart from the email services, there must be some other essential tools and features that you should look for before you make your decision. These features consist of a simple and intuitive user interface along with tools like a calendar to make event scheduling convenient, cloud storage, and inbox.
  • Price: Checking the price details is also one of the most important factors. You should check what services you are getting and if it is affordable for you or not. Always compare the services according to the features they provide and at what rate you are getting those services.
