The report card
Best for inbox placement for B2B email senders
Folderly is a set of deliverability products: sender reputation upkeep and placement monitoring per mailbox, placement tests, and alerts. It is priced per mailbox, from $96 a month at the smallest size, with a minimum commitment. DMARC is a pilot and Mirror is in beta.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | $96 per mailbox a month on yearly billing, falling to $56 at 25 or more. Five mailboxes would be $480, far past the category's $75 dearest-tenth line. |
| Free plan and trial | C | Inbox Insights Free gives 2 placement tests a month, and Pulse alerts are $0. A small taste, not a working setup. |
| Features | C | Placement tests, reputation upkeep, DNS and IP checks. DMARC is a pilot and Mirror is in beta, and it says it is not a standard warm-up service. |
| Ease of use | C | No store rating on record. A web suite with several products and per-product plans to sort out. |
| Platforms and integrations | B | Web, with Google Workspace, Outlook, SendGrid, AWS, Elastic Email and Slack. |
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 Folderly is for
- Fits if you send B2B email from a handful of mailboxes and care where it lands

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.
Your call
You could make the core of Folderly for yourself: reports.
What you would give up is listed below. Whether that is worth the price is your call. It costs $948 a year.
What you could make
- Reports: an app builder makes this well.
- It runs in a browser, which is where something home-made would run too.
What you could not
- Reading the reports inbox providers send about your domain.
- It plugs into other products, Google Workspace, Microsoft Outlook and SendGrid among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Folderly’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.
