David Bloomer - PeerSpot reviewer
Lightweight, simple, and robust; easy to maintain and doesn't require a lot of system resources to run
Kerio Connect does as advertised, so there are no real issues with the product itself. It's developed regularly, so there are constant updates. Possibly, the support and development have lessened since they've sold the company, but as far as the product itself is concerned, there isn't anything that I would suggest needs improvement. If I'm being picky, Kerio Connect uses a proprietary, mappy atom for Outlook, and it would be nice if they used a native mappy connection instead, but that's the only additional feature that I would like to see in its next release. If they have native Outlook map integration, that would be great, but other than that, it's got all the functions that I think a mail server should have.
Salem Shafik - PeerSpot reviewer
Zoho Mail suits small businesses well but can improve user organization features
For the admin side of Zoho Mail, they need to add features for organizing users in organizational units. We currently only have the ability to add users to groups, but some admins need to organize users in organizational units and apply security policies or other configurations based on these units.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"KerioConnect has integration with 365. We can use Outlook, which has its client and can be used with Apple devices. It integrates with the App Store and Microsoft Office. It has a smart router. The spam filtering and antivirus are good."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"We have contacted technical support a handful of times and received some assistance."
"The solution is easy to maintain, unlike Exchange. It's easy to create multiple domains and back up and restore if needed. It also has good security features like anti-spam and antivirus."
"What I like most about Kerio Connect is that it supports ActiveSync, and that is its most critical feature. The solution is also a nice, simple, robust, and stable mail server."
"The user interface is good."
"It's relatively simple to use."
"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."
"Zoho Mail is a cost-effective solution."
"Their experience with Zoho Mail has been positive, as customers haven't complained about anything."
"The notifications, scheduling, and meetings are all integrated."
"Zoho gives you a set amount of free users, so you can use it until you reach the limit and see if it's something you want to adopt. I tried it and stuck with it. Since then, I've seen a lot of improvement. I already think it's top-notch, but I believe it will become one of the best in the world."
"Zoho Mail is a stable product."
"It also offers the search functionalities. For end users, the search is quite easy to use. There are a few tabs to select to find exactly what you're looking for. It's pretty simple. As long as the data is available, you can use filters like from whom, to whom, subject, attachment, and even use advanced settings. It's pretty nice."
"It uses an alert system and other monitoring tools."
"Zoho Mail organizes your email well, and you can do a lot of things if you use other Zoho applications along with it."
 

Cons

"I would like to see better support from their support team."
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."
"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."
"Having a native Outlook map integration would make Kerio Connect better."
"KerioConnect is stable as long as you use a strong password."
"The solution could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"
"The solution's meeting plans and online virtual activity task list could be improved and made more seamless."
"Zoho Mail needs to add an IT system management feature."
"The interface isn't quite good. Everything looks a little low-quality."
"I once tried doing bulk email sending with Zoho Mail, but it was declined. I didn't realize it was declined until several hours later when I checked for responses."
"Zoho Mail needs to improve its integration because direct integration is not possible with many applications."
"The solution’s stability could be improved."
"They could increase the available space which is currently 5 GB. Gmail provides 15 GB of storage space, which would be more useful."
"We face some challenges in our current architecture with the introduction of data privacy regulations. When you are sending a calendar invite to a group of people for a meeting or an event, there is no structure for privacy. You can't hide all the contacts. Maybe that feature exists, but I don't know where it is."
 

Pricing and Cost Advice

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The pricing is about $3 per mailbox per month."
"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."
"The price of Kerio Connect is better when comparing it to others solutions."
"One of the reasons people use Zoho in Nigeria is because we can pay for it in Naira. It's very affordable already. For example, we can get Zoho Mail for somewhere between 1000 naira per user, which is less than one dollar. In my opinion, it's very affordable."
"Zoho Mail is more cost-efficient than its competitors."
"Zoho One has all 50 applications in it, and Zoho Mail is part of it. Zoho One is about 35 GBP per person per month. It includes Zoho Projects, Zoho Mail, Zoho CRM, and everything else."
"The solution’s pricing is very reasonable."
"The solution is not costly."
"If you have ten users, for Google, you'll pay $100. With Zoho Mail, you'll only pay $30 to $40."
"There is no license required to use Zoho Mail."
"The solution is more affordable compared to other products. It is cheap."
