Contact

Pick the channel that fits — we read all of them and reply on business days. If your question is time-sensitive and you're already a customer, the in-app support channel is the fastest route.

Support

Existing customers: open a support ticket from the dashboard (the ? icon in the top bar). Or email support@simrelay.io if you can't sign in.

Trial users and prospects: email hello@simrelay.io and we'll route you. Mention what you're evaluating — that helps us answer the question that matters.

Sales

For Enterprise plans, custom contracts, regulated industries, or volumes above the published plans: send us a sales inquiry and we'll schedule a call if it makes sense. You can also email sales@simrelay.io if you prefer.

Security

If you've found a security issue: security@simrelay.io. PGP key on request. We acknowledge responsibly disclosed reports within two business days and won't take legal action against good-faith research that stays within the scope of our responsible-disclosure policy.

Press & partnerships

For media inquiries, integration partnerships, or anything else that doesn't fit the buckets above: hello@simrelay.io.
