1. Email Storage: One major difference between Yandex Mail and Zoho is the storage capacity they offer. Yandex Mail provides users with 10 GB of free storage, while Zoho offers 5 GB of free storage. This difference in storage capacity can be important for users who have large email attachments or who receive a high volume of emails.

2. Email Attachments: Another significant difference between Yandex Mail and Zoho is the maximum size limit for email attachments. Yandex Mail allows users to send attachments up to 30 MB in size, whereas Zoho puts a limit of 25 MB on email attachments. This limitation can affect users who frequently send or receive large files through email.

3. Custom Email Domains: Yandex Mail and Zoho also differ in their support for custom email domains. Yandex Mail allows users to use their own custom domains for email addresses, which can be useful for businesses or individuals who want a more professional email address. Zoho, on the other hand, requires users to upgrade to a paid plan in order to use custom email domains.

4. Email Forwarding: While both Yandex Mail and Zoho support email forwarding, there is a difference in how they handle it. Yandex Mail allows users to set up email forwarding for free, whereas Zoho requires users to upgrade to a paid plan in order to enable email forwarding. This can be important for users who need to forward emails from their Yandex Mail or Zoho accounts to another email address.

5. Email Filters: Yandex Mail and Zoho also differ in their email filtering capabilities. Yandex Mail provides users with a comprehensive set of email filters, allowing them to automatically organize and sort their incoming messages. Zoho, on the other hand, offers more limited email filtering options, which may not be as flexible for users who need advanced email management features.

6. Integration with Other Services: Finally, Yandex Mail and Zoho differ in their integration with other services. Yandex Mail provides seamless integration with other Yandex services, such as their cloud storage platform Yandex.Disk. Zoho, on the other hand, offers integration with a wide range of third-party services, such as CRM and project management tools. This difference in integration options can be important for users who rely on specific services in their daily workflow.

In Summary, Yandex Mail and Zoho have significant differences in email storage, attachment size limits, support for custom email domains, email forwarding, email filtering capabilities, and integration with other services.
