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.

Cons

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

"KerioConnect is stable as long as you use a strong password."

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

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

"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."

"Having a native Outlook map integration would make Kerio Connect better."

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

Pricing and Cost Advice

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

"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."

"The pricing is about $3 per mailbox per month."

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

"The solution is not costly."

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

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

"The solution’s pricing is very reasonable."

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

"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."
