Changes to this list
We'll add a subprocessor to this page, and email workspace owners, at least 30 days before it starts processing customer personal data. If you object on reasonable data protection grounds, tell us at contact@sendgecko.io during that time and we'll work out a solution with you.
We also review this list regularly and remove companies we no longer use.
