When you use an email client, you may open your email addresses created with different email providers.

Many email providers also have their own email clients, like Outlook and Gmail — you can create your email address and use their own product to open it and manage conversations.

But also, there are “pure” email clients like Mailbird whose goal is to help you effectively manage your email from different providers. The unified inbox makes it possible for you to combine all of your emails from different accounts in one place.

Criteria to Choose an Email Provider

Choose an email provider that works seamlessly with your routine.

User Support

  • Fast-tracked tickets to get to the bottom of issues quickly
  • Prioritized onboarding experience

Mobile Access

Referring back to customization and tools, your email should make it easy for you to forward tasks to third-party apps like Dropbox or Trello from your phone.

We have summarized our research on the top email providers in this table for you.

Google Workspace seems to be the top email provider for people and companies looking for value by virtue of its access to other tools, like video conferencing. The downside would be that there is no dedicated single app for mobile or desktop. The desktop issue is remedied by using an email client that allows Google Apps to be integrated and save you from bouncing around.

Zoho Premium is a great option if you share analytics with a lot of external clients, thanks to their white labeling. It comes at a reasonable price as well.

Yahoo seems to be a clear winner if you require an unprecedented amount of storage capacity, but they don’t offer nearly as many tools or security features as our other contenders.

For users determined to maintain a tight ship security-wise, it’s clear ProtonMail Professional is the way to go. Their open-source platform is a huge selling point. It’s worth noting that ProtonMail is not great for massive email blasts — their anti-spam ethos will hurt your efforts here.
