LitInboxes is an email deliverability monitoring platform for businesses and agencies that depend on email for revenue, customer communication, or client results. It covers DNS and DMARC monitoring, blocklist and reputation tracking, spam score analysis, and email verification, all in a single dashboard.

Continuous DNS checks (SPF, DKIM, DMARC, MTA-STS, BIMI), automated sweeps across 8 high-signal blocklists (24 on Pro), DMARC report ingestion, Google Postmaster Tools integration, IP and domain reputation tracking, and instant alerts by email, Slack, Discord or webhook.

Every plan sweeps 8 high-signal blocklists: Spamhaus ZEN, Spamhaus DBL, Barracuda, SpamCop, CBL, PSBL, Mailspike, and the Sender Score blocklist. Pro adds 16 more, for 24 in total. The number is deliberately small. Those are the lists mailbox providers actually consult, while the long tail of minor lists rarely changes real inbox placement and some of those operators charge for removal.

LitInboxes checks your domains around the clock. When something drifts, like a DNS record change, a new blocklist listing, or a reputation drop, you get an instant alert by email, or in Slack, Discord or a webhook on Pro, with what changed and how to fix it, before it costs you deliverability.

LitInboxes verifies addresses through a syntax, MX, and SMTP cascade, flagging risky roles, disposable domains, and catch-alls before you send. You can verify a single address or upload a CSV to clean an entire list.

Your email content is scored with Rspamd, the same engine many mail servers run, and an AI pass explains each triggered rule in plain language. You get a breakdown of triggered rules, link and image ratios, spam trigger words, and subject line issues, with concrete fixes for each. Content scoring is separate from the infrastructure checks, which cover authentication, blocklist listings, and sender configuration.
