About

WillItInbox helps SaaS teams, developers, agencies, newsletter senders, and operators test whether important emails are technically ready before sending.Instead of guessing from a template preview or waiting for customers to report missing emails, teams can generate a unique test inbox, send a real email from their app or ESP, and get a practical deliverability report across authentication, DNS, headers, content, links, TLS, DMARC, and sender infrastructure.The platform also includes email validation for individual addresses and CSV lists, with signals such as syntax, MX, SMTP evidence, catch-all, disposable, role-based addresses, typo suggestions, provider detection, and confidence scoring.For ongoing operations, WillItInbox includes sender domain monitoring, DMARC report visibility, sending-source checks, API keys, webhooks, and developer workflows for pre-send QA.It is not an ESP, warmup tool, or guarantee of inbox placement. The goal is to make technical email risk visible, explain what to fix first, and give teams a repeatable workflow before sending password resets, billing emails, onboarding messages, newsletters, or campaigns.
