Zoho Mail

Pros

Zoho Free Mail is a great free software that has fantastic capabilities. The ability to add up to five users for free and different groups such as support, info, no-reply, etc. are powerful for freemium software.

Cons

It's hard to set up if you don't know what you're doing. It requires adding and editing entries to you DNS host server for your domain hosting. If you don't know what that is, you might want to consider another solution.

Pros

Zoho Mail worked well as a provider for my email on my custom domain. It has all of the features you would need out of a typical email provider, like Gmail​ or Outlook. It was simple to set up, just by adding an MX record into my DNS which took until 5 minutes. The UI is simple but powerful, and their advanced search tools helped me find emails from long ago that I wouldn't be able to find otherwise.

Since my only user was myself and an additional service account for miscellaneous sending purposes, I was using the "free" version, which is fully featured, but limited to 5 users. While the free version includes quite a lot of mail features, it is ultimately limited on mail storage, eventually causing me to move away. The free version also included access to some of Zoho's other products, including their contacts and calendar suite (expected with any email provider these days), as well as their office suite (think Word/Excel/Powerpoint). These were nice features to have included, but I ultimately did not use them too much, except for Contacts and Calendar.

Cons

Zoho is the underdog in the category of SaaS business suites, competing against GSuite and O365. While the product is fully featured and includes plenty of powerful tools, what it lacks is widespread support and integration, which ultimately made me move to O365, after using Zoho for 5 years. Their propriety storage and document solution are​ basically unheard of compared to Office Online (with OneDrive) and Google Docs (with Drive). Their IMAP/POP3, CalDav, and CardDav solutions are basic and fragmented, though the features are there. Furthermore, with the free account, I didn't get/expect any customer support so any problems were left to myself to fix (not many came up anyways).

Primarily, you lack integration with third parties and industry leaders with their services. They don't provide many plugins or connectors to external parties, and when they do, the options are lackluster. Don't expect to be able to automate things with Zoho.

Pros

I have used Zoho for a short time, but I can judge that Zoho Mail is the best at giving you professional mail, and what I like most is that you can get a lot of features like message storage space that is enough for your use and all this is free for a lifetime and I have never had any problems with mail as it receives and sends messages without problems or delays, so far I like the site and it is easy to use. I recommend Zoho to everyone who wants your professional mail for free for life with great features, and if your workspace is bigger, they also offer various plans that you can subscribe to.

Cons

I had no problems using the site, either at first when registering and linking the site to my domain. You ran into some minor issues, and depending on the company the domain was leased from, you might not see these issues. Each company has an explanation on the site about how to connect the DNS settings, but the company that I rented the domain from did not have a detailed explanation

Pros

Free platform to set up and manage multiple email addresses for a custom domain. It's super easy to set up individual email accounts and groups.

Cons

While creating email accounts with easy, managing them was not so much. Often you would get errors that made no sense even though everything seemed to be working. Also, the user interface could be improved as it seems a bit dated and clunky. And email classifications such as Newsletter and Notification would often mis-categorize emails causing you to miss important emails at first.

Pros

It’s a web based service with quick setup and ease of use. I like it’s security features and does its job well.

Cons

There is nothing that you can complain about this software. It’s easy to use and setup. I have had zero issues since 5 years of use.
