Contact Stack0

Anything that is not working: failed sends, upload errors, jobs that never finish, API responses you did not expect. Include your organization slug, the project, the environment, and a request ID if you have one. That usually turns a round trip into an answer.

Typical reply: Within one business day

Volume pricing, invoicing instead of card payment, a security review before you sign, or a question about whether Stack0 fits what you are building. Tell us the products you need and roughly what volume.

Typical reply: Within two business days

Vulnerability reports and anything touching the security of the platform. We do not run a paid bounty programme, but we acknowledge every report, keep you updated while we fix it, and credit you if you want the credit.

Typical reply: Within one business day

Invoices, receipts, tax details, plan changes, and refunds. Most of this is self-serve in the dashboard under Settings, so check there first: you can change plan, download every past invoice, and update your tax ID without waiting on us.

Typical reply: Within two business days

Data access, export, and deletion requests, plus data processing agreements. Our Privacy Policy sets out what we store and for how long.

Typical reply: Within 30 days, as the policy requires
