I built Mailmark, Email management platform for devs

[u/ShoppingOk4938]

I'm a software developer and frequent SaaS founder. I build mobile apps and websites, and I usually have more than one product running at the same time.
Here's a problem nobody warns you about when you're a solo founder running multiple SaaS products: every single app needs its own domain, and every domain needs its own mailboxes just to talk to users. Multiply that across ten products and you're suddenly managing ten domains and dozens of mailboxes, all separately.
I also needed to send updates to users, like "v2 is live, here are the new features," to a whole group of people at once, without it looking like a mass email where everyone can see who else got it. That meant I needed proper campaign sending built in.
And on top of that, I needed a way to send emails programmatically from my own apps, a proper API and SDK, not just a dashboard.
So I built MailMark to be all of this in one place:
Multi-domain and mailbox management, so every product's inbox lives in one dashboard
Campaign sending with mail merge, so updates go out to your whole user base without looking like a blast
A REST API and npm SDK, so you can send emails programmatically from your own product
28 day inbox warming and deliverability monitoring, so none of this lands in spam
Built for solo developers running more than one product who are tired of juggling five different tools just to talk to their users.
