    Mailbird Lite is not just an email client: it is a communication platform to which you can add all sorts of apps and extensions. Its worth paying for the pro version, however, as most of the best features are unavailable in the free version.

    "Mailbird is a downloadable program that integrates all of my email applications into one user friendly program. It makes emailing clients a lot easier especially since I can easily access the email interface while offline too instead of having to get online every single time. It is also extremely affordable."

    "I was looking for a reliable email client, i downloaded claws mail and was surprised at all of the features offered in this simple, efficient email service. It has mail filtering, it can handle IPv6, and you can even set up an account just for sending mail. It looks pretty basic, but it makes up for that with its super fast speed."


Did you know almost 2.7 million emails are sent every second? This number is expected to reach 246 billion before 2020. That's more than 30 emails for every person on earth, every day. Of course, not everyone sends 30 emails in a day. In fact, very few people do. But, many businesses send thousands of emails daily. Some people even have jobs that require them to do digital communication. Yes, businesses use the best email clients as their primary way of communication as it helps them to grow. It will also lead to new customer acquisition and keep them. Actually, 73% of millennials favor email as their number one means of business communication. That is why companies and businesses automate their campaigns in some way or the other. Moreover, email marketing is now vital to their Return on Investment (ROI). This is because the ROI of emails is four times higher than other marketing formats such as social media, direct mail, and paid search. Surprisingly, email marketing generates $38 in ROI for every $1 spent. Isn't that amazing?

Unfortunately, not all the emails sent are being opened. But, emails have the best chance of being opened within the first hour of arriving in the recipient's inbox. Moreover, email recipients will decide whether an email is attention-worthy in zero to three seconds. You can also test the best days and times to find out when your audience is most active when checking their emails. This will help you increase the open rate of the emails you send.

    "It's a nice looking app. The transition between using it on my macbook and on my iphone is seamless with very little difference in using either one. The only thing I don't like is the pricing. It's quite expensive as an iOS app but the Mac version is even more expensive. Still worth considering though if you don't mind the price."

    Inbox by Gmail

    Inbox by Gmail was an email service developed by Google with a limited invitation-only basis aiming to improve email productivity and organization through several key features. It was shut down by Google on April 2, 2019. *NO LONGER AVAILABLE*

    "being skeptical of anything that disrupts my custom email settings, I received an invitation to use the gmail inbox app. after a introductory infographic I adjusted my settings and gave it a go. After all, it´s for free, I thought. I compared my ordinary gmail inbox with the one displayed through the new app, that seemed more colorful. Attachments and pictures are visible at the preview, that being the time-saving feature talked about in the promo. And alas, no advertising ___ like the previous Gmail has morphed to. Let´s see the next days, I hope it stays that pleasant."

    "I tried out Type Mail when I was looking for a new app that might work better for emailing my clients than the stock one that came with my phone, and overall it worked out pretty well. It makes sending out emails to an entire group simple, especially because I can share those groups with my staff so they can use them too. And I like the VIP notification system, since I can set things up to only get notifications about emails from specific people I was waiting to hear from, instead of getting a notification from every single email that shows up."

    "Never paid much attention to this particular app as I always thought that its use case would be too limited to Microsoft and its ecosystem. Gave it a shot on my iphone and I regret not having tried it sooner. It's really a solid email client for iOS users and anyone looking for the best email client should check this one out."

    "I was thinking of something that lets me review my email without having to open internet. I have tried Opera products before and I liked their easiness of use and low relative data use, so I tried the Opera Mail client. The home screen is not clogged and gives a relaxed mood. It took me a while to sync but I attribiuted it to my slow data connection. I can sort an label my mails anyway I want and that makes me use my email caring less about it.. which seems the main goal . good. "

    "This is a useful little app that has really enhanced my experience when using GMAIL. It allows me to tab over to GMAIL more easily which is important as I keep a lot of browser windows open. While this feature alone is worth it to me, it adds a couple of other useful features such as more visible access to notifications and such. I might consider switching to paid but right now I'm just glad to have a more accessible interface than GMAIL provides on it's own."

It is not an email replacement , but allowed me to use myr downtime to quickly remove the noise and stress. When I sign into my e-mail account, my new messages appear as a stack of cards. Simply flick messages up to archive, or flick them down to keep in your inbox for later. I was also able to tap a message to view its full contents, and compose a short reply."
