The inbox that knows
your customers.
A customer emails you. You see what they bought, when, and how much they've spent. You reply. Done.
What you get
Four things. Done well.
conversations
A customer replies to a thread from three months ago.
You see the whole history. You don't ask them to repeat themselves.

FAQ
Questions.
What is SuppyHQ?
An email inbox for solo developers who sell digital products. Connect Polar or Stripe, get a support inbox with full customer context. Know who's writing you before you reply.
Who is this for?
You sell software, courses, or digital products. You have 10 to 500 customers. You handle support yourself. You're tired of checking Gmail and cross-referencing your payment dashboard.
How does inbound email work?
You get a unique support email (you@suppyhq.com). Put it on your website. When customers email, conversations appear with their full purchase history.
Can I use my existing email?
Yes. Forward your support@ email to your SuppyHQ address, or BCC it on replies from Gmail.
What about AI?
Bring your own API key (OpenAI or Anthropic). SuppyHQ generates a tactical brief about each customer — loyalty level, churn risk, how to approach. Optional, not required.
What does it cost?
$19/month after beta. Right now it's free. Early users lock in free access.
Is it really free?
During beta, yes. No credit card, no catch. When we launch pricing, early users keep free access.
Who built this?
Carlos Castellanos. Solo developer. I built this because I needed it for my own products.
