Email is the whole channel:
We don't publish a phone number or a street address. Support runs over email, answered by the people building the product. If you need a postal address for a legal notice, ask at the address above and we'll give you CarbonAccounting's.
Press, partnerships, security reports and data-deletion requests all go to the same address. A human reads everything; replies usually land within a day or two.
