The report card
Best for large senders who want deliverability help from people
MailMonitor tracks inbox placement and adds a customer success manager and audits on top. It starts at $1,000 a month billed annually, and the vendor says it is not for small senders or cold outreach.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | From $1,000 a month billed annually, against $49 for the dearer quarter of the category. It is a service with people attached, which is why it is a D and not an F. |
| Free plan and trial | F | No free plan and no trial is listed on the pricing page. |
| Features | C | Placement analytics, authentication audit and blocklist monitoring. The entry plan covers B2C seed inboxes only; B2B tests need the $2,000 tier. |
| Ease of use | C | No rating on record. Onboarding and a success manager are included, but the vendor asks you to check eligibility first. |
| Platforms and integrations | C | Web only, with no integrations listed. Custom API work is on the top tier. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who MailMonitor is for
- Fits if you send over 10,000 emails a year to an opted-in list
- Works for senders who want a named person to fix deliverability problems
Who it is not for
- Skip it if you are a small sender, as the vendor says you are not the target
- Not for you if you rely on cold outbound without a warm-up or opt-in plan
- Pricey if you add it up, at $12,000 a year before the first upgrade
- Watch out: B2B placement tests and 24/7 monitoring are on the $2,000 tier
- Watch out: there is no free plan or trial to try it first
Good to know
Good for
- High-volume senders whose revenue depends on email
- Teams that want an expert to guide fixes, not only data
- Enterprises that need custom API integrations
Worth knowing
- Plans start at $1,000 a month, billed annually, and the page says to check eligibility first.
- The vendor says it is not a fit for senders relying only on cold outbound without a warm-up or opt-in plan.
- It says a fit means sending over 10,000 emails a year, so small senders are not the target.
- The Foundation plan covers B2C seed inboxes only; B2B placement tests need Strategic Partnership.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of MailMonitor you could make: reports. What surrounds it you could not. The 2 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 60 of the 61 other email verification and deliverability tools grade higher. It costs $12,000 a year.
What you could make
- Reports: an app builder makes this well.
What you could not
- Reading the reports inbox providers send about your domain.
- An API that other software can build on.
What this rests on. MailMonitor’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
