MXToolbox is where most of us learned to run a blacklist lookup. Its Delivery Center product packages that heritage into a monitoring suite (DMARC, blocklists, DNS configuration, delivery reports) aimed at IT teams, priced at $129/mo.

LitInboxes covers the same monitoring core for solo senders and small teams at $49/mo for the same 5 domains, and adds the send-side tools (verification, AI spam analysis) that an IT-oriented suite doesn’t carry.

LitInboxes vs MXToolbox: the short answer

MXToolbox Delivery Center is an IT-team monitoring suite. LitInboxes is the same monitoring core priced and worded for the person who sends the mail.

Scope. Delivery Center covers DMARC reports, blocklists, DNS configuration, inbound mail flow, and inbox placement analysis. LitInboxes covers DMARC, blocklists, DNS drift, and reputation, and adds email verification and AI spam analysis, but does not do inbound flow monitoring or placement testing.
Price. Delivery Center is $129/mo for 5 domains. LitInboxes is $49/mo for the same 5 domains, and $99/mo for 50.
Cadence. LitInboxes re-checks every monitored domain every 6 hours and alerts on the change, not on a schedule.

What MXToolbox does well

Breadth and pedigree. Delivery Center monitors SPF/DKIM/DMARC compliance, processes DMARC reports, watches blocklists adaptively, reports on delivery performance, and monitors inbound mail flow. The free ad-hoc lookup tools remain the industry’s reference. Delivery Center Plus ($399/mo) adds SPF flattening and dedicated expert support.

The trade-off is price and audience. $129/mo is an IT-department line item, the UI assumes an admin, and there’s nothing for the sending side of the job: no list verification, no content checks.

Where LitInboxes is different

Same monitoring core: DMARC reports, blocklist/reputation watch, continuous SPF/DKIM/DMARC/MTA-STS/BIMI record checks, alerting on drift.
Google Postmaster Tools integration: Gmail’s own reputation data alongside your DNS and blocklist status.
Email verification: SMTP-cascade verification built in (500–50,000/mo by plan).
AI spam analysis: content scored before you hit send.
Built for senders, not sysadmins: one dashboard a founder can read, alerts that say what to fix.

How do I switch from MXToolbox to LitInboxes?
