One address for everything below.
Reporting a bug, asking for something that doesn’t exist yet, or telling us what was confusing? Use the report form — no account needed, and it reaches the same person.
Support
Account, billing, integration or a list not behaving the way you expect. Include your tenant's slug or a publishable key prefix if you have one — never the secret key itself.
Security reports
Found a vulnerability or a way tenant isolation could be broken? Report it to the same address. See /security for what is and is not defended today, and what a report should include.
Enterprise / pricing
Volume, a custom domain beyond the Pro tier, or a question the pricing page does not answer. Say what you need. Mail goes to one person and is answered as soon as practical; there is no guaranteed response time, and no sales queue to route through.
