One address, four kinds of message. Pick the one that fits and the subject line is filled in for you — it is what routes your message, and it is why the reply times below are keepable.
A result that failed, came back mangled, or charged credits it should not have. Include the time it happened and what you uploaded — not the file itself, we cannot accept attachments of other people's photographs by email.
Access, export or deletion of your data, and questions about which processors handle an upload. Write from the address on the account so we can identify it.
Three questions come up often enough that the answer is already written down: what a run costs and what is free is on the pricing page, how long we keep your files is in the privacy policy, and what we will not generate is in the terms.
