For founders who sell software on Stripe or Polar
AI does the toil. You do the touch. Cold pitches go to Spam, and the customer who paid you goes on top, with their plan and your last answer ready.
Free for the first 10 people who write in. No card.
A double charge from a paying customer goes on top, with her plan beside the email.
Cold pitches wait in Spam. Mark one company three times and SuppyHQ offers a rule.
One page per customer: every purchase, refund and conversation, plus your team's notes.
Questions you answered before, with your answer ready. Send or Skip.
Three people, one outage. The sidebar lists the others, and your answer to the first is ready.
Connect an agent from your terminal. It replies for you, and you get 30 seconds to cancel.
The widget inside your app. It knows who's signed in, and the message arrives as email.
Cold pitches, SEO offers and "partnership" emails from strangers go to Spam before you see them. A refund, an upset customer, someone leaving or locked out, or a failing payment goes on top, under Can't wait. Everything else waits its turn, oldest first.
It only holds back a stranger's first email, and only when it's sure. When in doubt, the email stays in your inbox. It never replies for you.
Mark the same company's pitches as spam three times and SuppyHQ asks to make it a rule. From then on it runs without any AI.

Love the new update
Stripe · Polar
Every email shows the plan, lifetime value and payment history before you read a word. A failing payment moves to the top on its own. Mark your best customers VIP and they sort first. No more opening Stripe in another tab to work out who's writing.

The fortieth "how do I export?" gets the answer you wrote the first time, already in the composer. Read it, change a word, send. If your old answer doesn't fit the new question, the composer stays empty.
"Can't sign in" and "the login page rejects my password" are the same problem. SuppyHQ matches by meaning, not keywords. When three people write about the same thing in one week, the sidebar lists the others, and the answer you gave them waits above your reply. On Fridays, the week's list lands in your inbox. That's how you find the bug before the tenth email.
Suggested replies never send on their own. You're still the one talking.

One command connects the agent you already use. It reads the inbox, pulls the customer's purchase history, and writes the reply into the composer.
Drafting and sending are separate permissions, and every send waits 30 seconds so you can cancel it. The email says who wrote it: "Sent by Claude on behalf of you."

Webhook signature verification?
Where do I find the webhook signing secret, and how do I verify the HMAC on my end?
Settings → Developers shows the signing secret. Verify with HMAC-SHA256 over the raw body and reject on mismatch. Happy to check a sample payload if you paste one.

FAQ
SuppyHQ is a support inbox for founders who sell software on Stripe or Polar. Cold pitches go to Spam, refunds and paying customers go on top with their plan next to the email, and your usual answer is ready in the composer. Solo is $29/month, and Teams is $29/month during the beta. Free for the first 10 people who write in.
Founders and small teams who sell software through Stripe or Polar and answer their own support email. If pitches are burying your customers and you keep typing the same answers, it's for you.
You can, for a while. A regular inbox delivers pitches because they're real emails from real people, and a chatbot only helps when you ask it. SuppyHQ works the moment mail arrives: pitches out, refunds and failing payments on top, the customer's Stripe or Polar history next to the email, and your past answers ready. No prompts, no copy-paste.
Only a stranger's first email can be held back, and only when SuppyHQ is sure it's a pitch, a scam, or a mass mailing. If the check is unsure or fails, the email lands in your inbox. Replies and people who've written before are never held. Spam is one click away, and moving a thread out of Spam makes that sender a real contact again.
No. Forward support@ to SuppyHQ. You can keep replying from Gmail and BCC your SuppyHQ address so the thread stays complete. Sending from support@yourdomain.com takes two DNS records.
No. SuppyHQ only reads from Stripe or Polar: plans, purchases and payments, shown next to each email. It never charges or refunds.
How keys and access workNot unless you allow it. Suggested replies never send. A connected agent can only send if you tick that permission, every send waits 30 seconds so you can cancel, and the email says an AI wrote it.
It's one person and one server, with encrypted backups every 6 hours. You can export every conversation, customer, and attachment as a zip from Settings at any time. Keep a recent export and you're never stuck.
On one Hetzner server in Germany: conversations, customer data, and attachments. TLS in transit, encrypted backups. I'm the only person with access. Postmark delivers the email, AI summaries go through OpenRouter, and TypeSafe sorts spam and urgent email. Nobody sells your data.
