About Willitinbox

WillItInbox is email deliverability and validation software for SaaS teams, developers, agencies, marketers, and newsletter operators that depend on outbound email.

Teams can generate a unique test inbox, send a real message from their app or ESP, and receive a practical deliverability report with checks across SPF, DKIM, DMARC, BIMI, DNS, reverse DNS, blocklists, TLS, headers, content, links, reputation, and sender infrastructure.

The platform also validates individual emails and bulk CSV lists using syntax, DNS/MX, disposable, role, typo, provider, catch-all, SMTP, suppression, and confidence signals. WillItInbox includes domain monitoring, DMARC report analysis, sending source visibility, provider reputation checks, API keys, webhooks, scheduled checks, incident diagnostics, inbox placement checks, team workspaces, and exportable reports.
