I built LitInboxes because you shouldn't have to guess whether your emails actually arrive.

The dashboard
This is the real product. Every domain you monitor gets a health grade, and anything that needs your attention comes with a fix, not just a warning.

Who it's for
The same monitoring underneath. What differs is the signal that breaks first, and what it costs.
Receipts, shipping updates and campaigns leave from different subdomains. When one drifts, support tickets tell you before your ESP does.
Read the use caseA launch is a two-week window with no second chance. If the list stopped receiving you months ago, the offer never got a fair test.
Read the use caseTen clients, ten DNS zones, no single answer to the Monday morning question: which of these is broken right now?
Read the use caseA filtered password reset is a churn event that looks like a product bug. Transactional email fails the way infrastructure fails: quietly.
Read the use casePast a few thousand messages a day, providers stop judging emails and start judging you. The numbers that decide it are published.
Read the use caseRun syntax, MX, and SMTP checks on every list so you stop sending to inboxes that bounce, trap, or complain.

Your content is scored with Rspamd, the open-source filter many mail servers run, rule by rule. Your infrastructure is checked separately: authentication, blocklist listings, and sender configuration. Catch both before they cost you.
Deliverability isn't a one-time check. We continuously monitor your domains and IPs for blocklist appearances, DNS drift, DMARC failures, and reputation drops so you can react immediately.

FAQ
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.
Every plan starts with a 14-day free trial. No charge until the trial ends, cancel anytime.
