For agencies and consultants
The client tells youbefore your tools do.
You look after sending for people who did not build their own DNS. Without one screen for every client domain, the first alert is a phone call, and the investigation starts with no history.

LitInboxes is an email deliverability monitoring platform for businesses and agencies that depend on email for revenue, customer communication, or client results.
The problem
Where it breaks for a portfolio
The work is not hard. Finding out in time is.
- 01
No single view of the portfolio
Ten clients means ten ESP dashboards and ten DNS zones, and still no answer to the only question that matters on a Monday: which of these is broken right now?
- 02
The client notices first
A missed listing or a DMARC failure surfaces as a complaint about missing invoices. You are now debugging live, in front of the person paying you.
- 03
You cannot prove the fix
You corrected the record last month. With no dated history of checks, there is nothing to show that the problem is gone, or that it was ever there.
- 04
Inherited setups you did not build
A new client arrives with three sending tools, two half-configured subdomains and an SPF record near the 10-lookup limit. Auditing that by hand is an afternoon per domain.
- 05
Reporting eats billable hours
Pasting DNS checker screenshots into a monthly deck is work you cannot charge for at a rate you would want to charge.
The fix
What LitInboxes does about it
Built for one workspace holding many domains. Read the limits below before you commit.
- 01
Fifty domains on one screen
Pro monitors up to 50 domains. Each one gets a health grade, the signals behind it and the issues that need a fix, sorted so the broken ones are at the top.
- 02
Alerts that arrive before the client
Checks run every 6 hours per domain. A changed record, a new listing or a DMARC pass rate drop raises an alert by email, or in Slack, Discord or a webhook on Pro.
- 03
A dated record of everything
24 months of history on Pro: every check, every listing, every reputation snapshot. That is your audit trail, and your proof of work at renewal time.
- 04
Shareable report links
Generate a link to a domain's health report and send it to the client. No login needed on their side, with an optional expiry. The report is LitInboxes-branded, not white-label.
- 05
An onboarding audit in minutes
One scan per domain covers SPF with its lookup count, DKIM per selector, DMARC policy and alignment, MTA-STS, BIMI and blocklists. The free SPF flattener handles the records that are over the limit.
In the product
The portfolio view
Domains needing attention first, with the reason on the card, and the healthy ones underneath. This is the screen that replaces ten browser tabs.
Dashboard
Your sending health at a glance.
Needs attention (1)
Healthy (2)
The dashboard, as it looks in the app.
The numbers
What you show the client
Everything here is dated, so it works as evidence rather than assertion.
Health grade per domain
One grade per domain computed from the underlying checks, so a portfolio can be triaged at a glance.
Bad looks likeAny domain that drops a grade between two checks.
Open issues with a fix
Each issue names the record, what resolved, and the corrected value to publish.
Bad looks likeAn issue that reappears, which usually means someone else is editing the zone.
Blocklist deltas
New listings and removals, per domain and per IP, as they happen rather than at review time.
Bad looks likeA listing on Spamhaus ZEN or DBL, which providers consult directly.
DMARC sources
Which sending systems authenticate for a client domain, grouped by source from the aggregate reports.
Bad looks likeA sending system nobody told you about, authenticating as your client.
The mechanism
What a portfolio needs that a one-off checker cannot give you
A DNS checker answers one question: is this record correct right now. Client work needs two more. When did it change, and what did it look like before? Those need stored state and change detection, which is the difference between a lookup tool and a monitor. Every check here is kept, so a record is not just right or wrong, it has a history.
The second requirement is routing. An alert that lands in an inbox nobody opens is not monitoring, it is archiving. Alerts go to email on every plan and to Slack, Discord or a webhook on Pro, so the notification arrives in the channel where client work already happens, with the diff and the corrected value attached.
The third is evidence. A retainer is easier to renew when the work is visible: a dated check history showing the broken state, the change, and the clean state after, plus a report link the client can open without an account. That is also the honest boundary of this tool. It is a portfolio monitor, not an agency platform, so plan around one shared workspace rather than per-client logins.
Getting started
Your first hour
Longer than the other segments, because you are onboarding more than one domain.
- 01
Add your own domain first
Learn the output on a domain you control before you point it at a client's zone.
- 02
Add each client's sending domain
Use the From domain their ESP sends with, and list up to three DKIM selectors per domain so a rotation cannot hide.
- 03
Route alerts where you already work
Email on every plan; Slack, Discord and webhooks on Pro. Send them to the channel where client work happens, not to an inbox nobody reads.
- 04
Share the first report
Generate a report link for the domain you just fixed. It is the fastest way to make a retainer feel worth paying.
Plan fit
Which plan fits an agency
Pro, $99/mo
Fifty monitored domains, the wide blocklist sweep, Slack alerts and two years of history, plus the REST API and MCP server if you want the data inside your own tooling.
- 50 monitored domains
- 24 blocklists monitored
- Email, Slack, Discord and webhook alerts
- 24 months of history
- REST API and hosted MCP server
Honest limits
When LitInboxes is the wrong tool
Three requirements this does not meet today.
- You need white-label reports under your own domain and branding.
- You need per-client logins with access scoped to one client's domains.
- You need to resell it as your own product. There is a partner program, but reselling under your brand is not supported.
Questions
Questions from this crowd
- Is there white-label?
- No. The app and the shared report links carry LitInboxes branding. If white-label is a hard requirement for your clients, this is not the right tool yet.
- Can each client have their own login?
- Not per client. A workspace has members, and every member sees every monitored domain in it. Client-scoped access is not built.
- How many domains can one workspace hold?
- 1 on Starter, 5 on Growing, 50 on Pro. The count is domains, not clients, so a client with three sending subdomains uses three.
- Can I resell it?
- There is a partner program with a negotiated commission rate and duration, and an affiliate program paying 20% of a referred customer's first 12 months. Reselling under your own brand is not supported.
- Can I build my own client dashboard on top?
- Yes, on Pro. The REST API exposes domains, checks, DMARC summaries, blocklist status, events and alerts with per-resource scoped keys, and the hosted MCP server lets an AI assistant query the same data.
- What do I show a client who asks for proof?
- The dated check history and a shared report link. Between them they show the state before your fix, the change, and the state after.
