Show HN: MailMark – Cold email tool where you own your domain and mailboxes

2•debasishbarai•1h ago
Hi, I am Debasish from India. I am passionate about building softwares. I started coding long ago around 2015 when android apps were built only Java. Kotlin was not a thing then. I built railify android app. That was the first time I built and shipped one product to the world. The journey did not stop after that. I built several other products. All of these are my side projects. I am not a software developer by profession. I am an electrical engineer working in a power plant in India. However, as I grew my product base, I literally own so many domains which are all related to my products. All have there mails setup to connect with the relevant ICPs, answering questions of users, solving doubts and also informing the users about any new release of the products. Maintaining all these domains and their email Ids, honestly speaking was difficult. So I started thinking about building something to solve this issue in particular. I built mailmark for this. Mailmark helps you add your domains i.e. abc.com, setup different mailboxes i.e. sales@abc.com, founder@abc.com, marketing@abc.com, updates@abc.com etc. All of these domains and mailboxes are accessible from the same unified UI similar to Gmail or Zoho. I also added one lightweight tracking system to the mails sent throughthis platform, which will show the status of the mails like delivered, opened, not yet delivered or rejected. Also, as it is focused on bulk mails, to the users, it works like email campaigns, similar to Gmass, where all the mails to recipients, will be individual separate mails. I can track all the mails statuses from a single window like the deliveribility status how many mails are delivered, opened etc. I have also built a developer feature where I can send emails programmatically with a key, similar to Resend. There is a lot more there in the product which I will definately like to discuss. Please do checkout the product. Here is the link: https://www.mailmark.dev Happy to answer questions here.
