Q: What is domain name parking?

Domain parking refers to a monetization service displaying ads on a landing page. MailboxPark does not park domains or display ads on your domain name. MailboxPark uses the email data your domain names are receiving and gathers that data to monetize for domain owners.

Q: What is domain email parking?

Email parking allows domain owners to monetize the email traffic sent to their domains. To park an email domain with MailboxPark, a customer points a domain’s email exchange record, or MX record, to our servers. By doing so, MailboxPark gains access to the email traffic sent to that domain and we resell that data to companies that send email.


Q: How much can I earn from partnering with MailboxPark?

Earnings can vary depending on a number of factors, such as volume and type of email traffic received by a domain, and the overall number of domains you possess.

Currently, MailboxPark pays partners based on the volume of commercial email sent to a domain; however, traffic originating from individuals, botnets, or any other non-business entities cannot be monetized at this time. At the end of the day, we prioritize quality over quantity. We are able to provide our partners with a better understanding of their earning potential after just a few weeks of monitoring. 

Q: Why have I not received a payment from MailboxPark?

We require a minimum payment threshold of $5.00 USD.

For those that have surpassed the minimum payment threshold, we issue payments on a net-7 basis, which means that our partners have their earnings disbursed within 7 business days of the previous month-end via their selected payment method.

If you have selected PayPal as your method of payment method, you should expect to see your payment within 24 hours of issuance. 

If you have selected Direct Deposit (ACH) as your payment method, there could be a 3-5 day delay in the payment showing up in your account. Also, Direct Deposit (ACH) is only available to partners with bank accounts in the United States.
