Customer support that doesn't run your life.

An email inbox for customer support. See who's writing and what they paid before you reply.

Six things.

It's email. Not chat.

Chat trains your customer to wait. Green bubble, typing indicator, every signal promises a reply any second. Email doesn't make that promise. They write a sentence, hit send, get on with their day.

Reply on your terms.

Answer at 9am in one batch, or after dinner, or once a week. Your customer never sees when you logged in — and doesn't need to.

Every purchase, every charge — before you read a word.

Sarah bought Fusionaly in January. She's spent $174. Subscription active. You see all of that before you reply.

A widget that becomes email.

One line of HTML drops a form on your site. They type, you get an email. The thread continues in your inbox. They never knew it was a form.

Your inbox sorts itself. VIPs first, then longest wait.

Default order is longest-waiting first. Mark someone VIP, they jump to the top. Nobody gets buried by a newer email.

Threads stay threads.

A customer replies to a conversation from three months ago. You see the whole history. They don't repeat themselves.

Polar and Stripe. Plug in once. Stay out of your dashboard.

01

Read-only Polar and Stripe keys, encrypted

Your API key is read-only. We can't charge, refund, or create subscriptions. Stored encrypted, sent over TLS.

02

Realtime webhooks

The moment Polar or Stripe fires an event, it lands in your inbox. No polling, no lag.

03

Pull your customers, or start fresh.

Day one: import every existing customer. Or skip it and only see new activity.

Where it lives, who can touch it: the stack →

You built it. You answer for it.

Every reply is from you. Not a bot. Not a tier-1 outsourced team. The customer reads your name on the response, written by someone who knows the product.

Live chat, email, or SuppyHQ?

Live chat eats your day. Email gives it back, but the most important message rarely sits on top. SuppyHQ keeps email's pace and fixes the order.

I've shipped Fusionaly, LogNorth, and Pomotto. I handled my own support from Gmail, cross-referencing my dashboard to figure out who was writing me. I built SuppyHQ so I could see the customer and reply in one place.

One person runs this. I have technical access to your data. I don't read it unless you email me for help.

Questions? karloscodes@suppyhq.com.

Questions.

Who is this for?

You sell software, courses, or digital products. You have 1 to 5,000 customers. You handle support yourself. You're tired of checking your inbox and cross-referencing your payment dashboard.

How do customers contact me?

Two ways. You get a unique address (you@suppyhq.com); put it on your site and customers email it directly. Or use the widget: one line of HTML that drops a button on your site. When a customer clicks, they type a message and the thread continues over email. Either way, every conversation lands in your SuppyHQ inbox with the customer's full history next to it.

Can I use my existing email?

Yes. Forward your support@ address to your SuppyHQ address and every incoming message shows up in SuppyHQ with full customer context. You can keep replying from your old inbox if you want. BCC your SuppyHQ address on the reply and it files the outgoing message in the thread too.

Can I send from support@mycompany.com?

Not today. Customers email yourname@suppyhq.com and replies go from there. If you'd use it, tell me. That's how features get built.

I sell multiple products. Does SuppyHQ handle that?

Yes. Connect your one Stripe or Polar account and SuppyHQ picks up every product, every customer, every purchase. A customer who buys two of your products shows up as one person with two purchases.

Does SuppyHQ send marketing emails?

No cold email. No lead lists. No strangers. Every message, including follow-ups and letters, goes to someone who already bought from you.

Is there an email limit?

5,000 outbound emails a month. That's plenty for a real business talking to real customers. If you're close to the cap for legitimate reasons, email me and I'll bump it. If you want to blast cold lists, we're not the tool.

How much does it cost?

$19/mo flat. Free until you've talked to more than 10 people — no card, no time limit. Past 10, you move to $19/mo, locked at your signup price for life.

What happens when I've talked to more than 10 people?

You get 7 days to add a card. After that, outbound replies pause until you pay. Inbound mail keeps flowing — nothing is lost. $19/mo, locked at your signup price.

Where is my data stored?

On a Hetzner server in Germany. Conversations, customer data, and file attachments, all in one place, on one server I own. TLS in transit. One person has access: me. We don't sell your data.

Can I export my data?

Yes, anytime. Request an export from settings and you get a zip with every conversation, every customer record, every attachment. No waiting, no tier requirements. It's your data.

What if you disappear?

Solo dev, single VPS, daily encrypted backups. Every conversation, customer, and message exports as a ZIP from settings. Your data doesn't depend on me staying online.

What if I delete my account?

Delete from settings. Your conversations, customer data, payment history, and files are wiped within 15 days. Your SuppyHQ address is retired forever. No one can take it or impersonate you.
