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

"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."

"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."

"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."

"This solution is our SMB alternative to Exchange, installed for more than forty SMB customers in a Linux environment with all of the collaboration features."

"It's relatively simple to use."

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

"The user interface is good."

"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."

More KerioConnect pros

"Zoho Mail is a cost-effective solution."

"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."

"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."

"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 Mail organizes your email well, and you can do a lot of things if you use other Zoho applications along with it."

More Zoho Mail pros

Cons

"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."

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

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

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

"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."

"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"

More KerioConnect cons

"The solution’s stability could be improved."

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

"Zoho Mail needs to improve its integration because direct integration is not possible with many applications."

"Zoho Mail needs to add an IT system management feature."

"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 doesn't need to be improved."

"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 initial setup of Zoho Mail can take some time because we have 30 to 35 users and we need to register each one. This can take one or two days to complete. The process could be better for administrators to register their users. If the setup interface was better in explaining the process it would be helpful to become more user-friendly."

More Zoho Mail cons

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 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."

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

"The solution is not costly."

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

"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."
