An MxToolbox Alternative When Nobody Has Time to Run the Checks
MxToolbox’s free plan checks one domain against blacklists weekly, and Delivery Center is $129 a month for five domains (October 2026). MxToolbox has been in email delivery for more than 20 years, and its free lookups are worth bookmarking. The catch is the same as with any good tool: somebody has to read what it finds and then do something about it.
With Cascadia you get
- Checked every day
- Delisting is our job
- Your own baseline
- Quiet until it matters
- Nothing to install
- Ninety days of history

Who Reads the Alerts
What Ships in the Standard Plan Here
With MxToolbox you get lookups, monitors, and reports, and on Delivery Center a long list of extras from DMARC reports to BIMI. Reading the alerts and requesting the delisting still sit with your team.
- The major blocklists checked every day
- Your domain and every sending address covered
- Delisting handled by us, at no extra cost
- Rechecked until the listing clears
- Reputation tracked against your own baseline
- Bounce and complaint patterns watched
- An alert only when something has changed
- The cause named, with what we are doing about it
- Ninety days of daily history kept
- Nothing installed, no access to your mailboxes
Where Cascadia Goes Further
A weekly check on the free plan can leave a listing in place for days before anyone hears about it. Daily checks shorten that gap, and somebody here acts on what they find.
Every Day, on Every Plan
There is only one plan here, and the major blocklists are checked daily on it, for the domain and every address you send from.
The Delisting Is Done, Not Linked To
A monitor that tells you about a listing has done its part. We name the cause, file the removal, and recheck until it clears.
One Domain at a Time, Priced Plainly
$49 a month for each domain we watch. No message volume tier and no feature ladder between you and the daily check.
Your Own History Is the Benchmark
Ninety days of daily checks, compared against your own baseline, so a change stands out against what is normal for you.
Who This Comparison Is For
You Have an Email Admin Who Likes the Tools
MxToolbox is a natural fit. The free lookups alone are worth bookmarking, and Delivery Center adds placement tests, complaint reporting, and mailflow monitoring.
Checks Only Happen When Something Already Feels Wrong
Most people open a lookup tool after a customer complains. By then the listing may have been there for a while.
Five Domains Is More Than You Need
Delivery Center covers five. If you have one domain and want it watched closely, a per-domain service can be the simpler purchase.
Choose MxToolbox if
- You have an admin who enjoys the diagnostics
- You want DMARC, BIMI, and placement tests together
- You need several domains under one plan
Choose Cascadia if
- Nobody on staff owns deliverability
- You want listings cleared, not just reported
- One domain matters and needs daily checks
Moving from MxToolbox in Four Steps
Keep the free lookups bookmarked. They are useful whatever else you run. What moves to us is the daily watching and the work that follows a listing.
- 1
We Take a Baseline Before Anything Changes
Where the domain and its sending addresses stand on the major blocklists today, and what your reputation looks like, written down as the starting point.
- 2
The Domain Goes on the Daily List
We need the domain and the addresses you send from. Nothing is installed and nobody here sees your mailboxes.
- 3
A Listing Gets a Cause and a Fix
If something turns up, the alert names the cause rather than the symptom and says what we are already doing about it. We handle the delisting and check again until it clears.
- 4
The Monthly Report Arrives Even When Nothing Happened
It lands on the first Tuesday on or after the 3rd, at 11 AM Pacific, covering the month just ended. The link to the full report stays open for 90 days.

MxToolbox Alternative Questions
Straight answers about how the two fit together, what each costs, and what we actually do.
See Deliverability MonitoringStill have a question?
What is an MxToolbox alternative?
Any other way of finding out whether your mail has a problem. That covers other blacklist monitors, seed testing tools, the mailbox providers’ own dashboards, and managed services like this one, where the checks and the follow-up are done for you.
How is Cascadia different from MxToolbox?
MxToolbox sells tools and monitors, and they are very good ones. We sell the watching and the work that comes after it. The major blocklists are checked every day for your domain and sending addresses, and when something turns up we deal with it rather than sending you a link.
Is the free MxToolbox plan enough?
For some people, yes. It checks one domain weekly at no cost (October 2026). If you send little mail and someone reads the alerts, that may well be all you need. Daily checks matter more when a week of mail going to spam would cost you real business.
Does MxToolbox offer a managed option too?
It does. MxToolbox lists managed services covering reputation, blacklist monitoring, and DMARC enforcement, with no price on its pricing page. We publish ours: $49 a month per domain.
Do you do inbox placement tests?
No. Delivery Center includes placement analyses and we do not. Our work is the daily blocklist and reputation watching, plus the delisting when it is needed.
Which blocklists do you check?
The major blocklists, daily, for your domain and every address you send from. The checks do not rely on your email provider.
What happens when we get listed?
We name the cause, handle the delisting ourselves, and check again until it clears. The message that tells you also says what we are already doing. It costs nothing extra.
Do you need access to our mail or DNS?
No access to your mailboxes, and nothing to install. We need the domain and the addresses you send from.
What history do you keep?
Ninety days of daily checks, so you can see when a listing started, when it cleared, and what your reputation did around it.
Will we get alerts on quiet days?
No. You only hear from us when something changed since yesterday. Mail being actively refused is raised as high priority.
What if I want to leave?
It is monthly, and it can be switched off in a day. Nothing was installed and we never had access to your mailboxes, so there is nothing to uninstall and no credentials to rotate. The checks simply stop.
Ready to hand over the checks?
$49 a month per domain, daily checks against the major blocklists, and delisting handled by us. Tell us the domain and we will start with a baseline.
