Security and privacy by design
Inbox Warmup protects SMTP credentials, isolates accounts, verifies payments server-side and keeps admin-managed server details hidden from customers.
Security practices built into the product.
Security pages should explain what is actually implemented, not make unsupported certification claims.
Encrypted credentials
Saved SMTP secrets are protected with the production encryption key.
Open page →Account isolation
Users can only access their own domains, connections, credits and reports.
Open page →Admin-managed SMTP privacy
Admins can configure private SMTP without exposing host, port, username or password to customers.
Open page →Backup and restore
Export and restore production data while preserving the same encryption key.
Open page →Payment verification
Paid credits activate only after backend payment verification.
Open page →Responsible limits
Hourly and monthly limits are enforced before messages are accepted for sending.
Open page →Ready to check your sending setup?
Start with a 7-day demo, connect your domain, verify DNS, and cancel before day 7 if you do not want the selected monthly plan to renew.
