Contact

The most useful thing you can send us is a fee that is out of date — with a link to the platform page that shows the current rate. Those get fixed fastest.

We aim to reply within two business days. We are a small team, so if you are pitching a guest post or a link exchange, the answer is usually no — but a correction to a fee table or a suggestion for a calculator we are missing is genuinely welcome.
