Are your emails going to spam?
Check your domain's email authentication. It reads public DNS records only, nothing is stored, and it works for any business, not just apps.
Why it matters
Gmail requires every sender to pass SPF or DKIM, bulk senders also need DMARC, and since November 2025 Gmail rejects more of the mail that fails. When that happens, password resets, receipts and invoices simply never arrive. Every Production-Readiness Audit checks and fixes this.
How the check works, and what it sends where, is in our privacy notice.
