For software founders on Stripe or Polar

Your support inbox, minus the pitches.

Cold pitches go to Spam. The customer who paid you goes on top, with their plan next to the email.

Free until you've talked to more than 10 people. No card.

The refund goes first.

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.

Stripe · Polar

It knows who paid you.

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.

Answer once. SuppyHQ remembers.

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.

Suggested replies never send on their own. You're still the one talking.

Settings → Export. It builds a zip and emails you the download link, usually within a minute.

Bring your AI. Keep the keys.

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.

I run support for four products, including Fusionaly, LogNorth, and Pomotto, on SuppyHQ. I built it after answering the same questions hundreds of times from Gmail. Why I built this →

One person runs this. Built for founders and small teams who still answer customers themselves. I have technical access to your data. I don't read it unless you email me for help.

Questions.

What is SuppyHQ?

SuppyHQ is a support inbox for software founders 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. $29/month flat, free until you've talked to more than 10 people.

Who is this for?

Software founders and small teams who sell 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.

Can't I just use my regular inbox and an AI chatbot?

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.

What if a real customer gets marked as a pitch?

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.

Do I have to leave Gmail?

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.

Can SuppyHQ charge or refund my customers?

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 work
Does AI ever reply on its own?

Not 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.

What if you disappear?

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.

Where is my data stored?

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.

Answer the refund before it's a chargeback.

Pitches out. Paying customers on top. Free until you've talked to more than 10 people.

Built by one founder. I use it on my own support.
