Domain Registration and Ownership

We offer domain registration services as a part of our package to clients. When we purchase domains on behalf of the client, we initially own and manage them. However, it's important to note that if a client ever wishes to take ownership of their registered domain, we can facilitate the transfer of ownership at no cost. We understand that clients may have specific requirements for their domain management.

It's worth mentioning that in order to provide uninterrupted services, we need to retain full control over the domains we register. This allows us to manage and maintain them effectively to ensure a seamless service experience.

Email Deliverability Guarantee

We are committed to ensuring the deliverability of your emails and aim to maintain a high level of email inbox placement. Our guarantee includes delivering a minimum of 80% of your emails to recipients' inboxes, ensuring they do not end up in spam folders. In the event that your emails do not meet this guarantee, we will thoroughly investigate the reasons behind the issue.

To be eligible for this guarantee, clients must adhere to best practices, including refraining from sending emails with spam-related content, incorporating unsubscribe links in their email communications, properly warming up email accounts for a minimum of three weeks before sending prospective emails, gradually increasing email volumes from one email per day to a maximum of 40 emails per day per email account, verifying all recipient email addresses before sending emails, and maintaining a bounce rate (percentage of emails sent to non-existing addresses) below 2%. Additionally, if the non-deliverability issue results from factors beyond the client's control and within the scope of domain performance, we will provide replacement domains at no extra cost. This guarantee remains valid for a duration of one year from the date of domain purchase, ensuring the sustained quality of our service.

We provide up to 4 domain replacements to each customer.

Email Recipient

Clients are prohibited from sending emails to personal email accounts. Our services are intended for use with corporate email addresses, and clients must adhere to this policy. It is the responsibility of the client to ensure that all recipients of their email communications have corporate email addresses.

Unsubscribe Policy

Clients are required to maintain accurate records of individuals who wish to unsubscribe from their email communications. In addition, it is mandatory that every email sent through our services includes a visible and functional unsubscribe link.

In the event that a client fails to honor unsubscribe requests, continues to send email communications to individuals who have opted out, or does not include an unsubscribe link in their emails, we reserve the right to cease providing our services to that client. Compliance with unsubscribe requests and the inclusion of unsubscribe links in every email is essential to maintain the integrity of our services and to uphold the privacy preferences of email recipients.

Governing Law

These Terms of Service are governed by and construed in accordance with the laws of Hong Kong. You irrevocably submit to the exclusive jurisdiction of the courts in that State or location.

Refusal of Service and Refund Policy

We reserve the right to refuse service to any customer. In such cases, a refund may be issued, excluding costs already incurred by us. If the customer has utilized our product for a specific period, the refund will be calculated proportionally based on the unused duration.

Use of Customer Feedback and Testimonials

Any feedback, testimonials, or information provided by customers via email or conversations with our staff may be used by us for case studies or testimonials without requiring explicit permission. We also reserve the right to publish on our website that a customer is using our product. However, customers have the option to request that their feedback not be used for such purposes or to have their logo removed from our website. We will honor such requests promptly.
