A seamless setup ensures smooth communication with comprehensive support

We remain a partner with Sophos and use XG S Firewalls without AWS implementation. We only use Sophos endpoint and Sophos Central. We host some clients on-premise while others we host remotely. The VPN connection is easy and proprietary, so it's not open to any other VPN clients. Communication with other mail servers is seamless. It can communicate with Gmail and Outlook without issues, provided the DNS settings are correct. We monitor our servers and security logs, implementing GeoIP blocking. We frequently block China and India IPs due to brute force attacks on our servers. We have extensive experience with KerioConnect. Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly. On a scale of 1-10, this solution rates an 8.

Customer Experience Consultant at Zoho

Has required technical improvements to better support advanced email feedback and user behavior tracking

Using Zoho Mail is quite easy. Users are able to track if the recipient has received, opened, or clicked on the email, thanks to a very good tracking system, and they can create large campaigns using the unlimited features of the email. The integration with Zoho Projects is a bit technical, as it's part of the CRM with specific routine tasks for projects. Efficiency-wise, it has been great in bringing teams closer together so that every project member can critique the progress of assignments. However, there is a need for improvement in communication style from one module to another. The main benefits that Zoho Mail brings include the ability to send large and secure mails. It integrates with Google clients, ensuring a high level of security and reduced spam. I have utilized it effectively, and clients trust emails from Zoho Mail because of its reputation as a reliable CRM software company.

Quotes from Members

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

Pros

"As long as the operating is stable, the Kerio connect will be very stable as well, so we don't have any problem with it."

"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."

"We have contacted technical support a handful of times and received some assistance."

"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."

"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."

"We have contacted technical support a handful of times and received some assistance."

More KerioConnect pros

"It uses an alert system and other monitoring tools."

"Zoho provides many excellent features such as Team Inbox where multiple users can join one inbox and check all emails, which is the best feature of Zoho Mail."

"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."

"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."

"The major use case for Zoho Mail is that it allows users to pay for subscriptions in local currency, which is Naira, Nigerian currency."

"The interconnectivity between these applications makes it particularly useful."

"Zoho Mail offers a strong platform for mailing and CRM functionalities, allowing users to build effective email campaign trails and offering security for email communications."

"The most valuable features of Zoho Mail are its security, integration with cloud storage, and wide range of features available. It integrates well with Outlook and mobile devices."

More Zoho Mail pros

Cons

"I don't particularly like this solution. I would not recommend this solution to others."

"The search and archiving documentation capabilities need to be stronger."

"I would like to see better support from their support team."

"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"

"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."

"We cannot compete with them because they're fully integrated with their applications."

"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."

"This is just a cost, it's not something that's driving our business forward; it's just foundational."

More KerioConnect cons

"Zoho Mail is not as mature as Google Workspace or Microsoft 365. Zoho Mail does not have the capabilities that Google Workspace and Microsoft 365 have, especially in terms of collaboration."

"The solution's meeting plans and online virtual activity task list could be improved and made more seamless."

"The support for Zoho Mail could be better for the setup."

"I have not worked on offline mode until now."

"The integration with Zoho Projects is a bit technical, as it's part of the CRM with specific routine tasks for projects. Efficiency-wise, it has been great in bringing teams closer together so that every project member can critique the progress of assignments. However, there is a need for improvement in communication style from one module to another."

"They could increase the available space which is currently 5 GB. Gmail provides 15 GB of storage space, which would be more useful."

"Zoho Mail is not as good as G Suite, which has integrated calendars."

More Zoho Mail cons

Pricing and Cost Advice

"The price of Kerio Connect is better when comparing it to others solutions."

"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."

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."

"The solution is more affordable compared to other products. It is cheap."

"The solution is not costly."

"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 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."

"Zoho Mail is more cost-efficient than its competitors."

"The solution’s pricing is very reasonable."

"There is no license required to use Zoho Mail."

"If you have ten users, for Google, you'll pay $100. With Zoho Mail, you'll only pay $30 to $40."
