ReceiptGuard
ReceiptGuard is a web app that continuously monitors and fixes deliverability for transactional emails (receipts, password resets, OTPs, shipping updates). Instead of being another email-sending provider, it plugs into what you already use (SendGrid, SES, Postmark, Mailgun) and watches real-world outcomes: inbox placement, spam flags, bounces, and provider-specific throttling. It runs automated checks for SPF/DKIM/DMARC alignment, domain reputation shifts, template changes that trigger filters, and sudden complaint spikes. When it detects risk, it generates concrete, provider-specific remediation steps and can open a “safe rollout” mode: gradual traffic shifting, template diff alerts, and fallback routing to a secondary provider. The product is aimed at reducing revenue loss and support tickets caused by missing critical emails. It’s not glamorous, but it’s measurable: fewer failed deliveries and faster incident response.
