How Folderly does it

Usage is per mailbox
The pricing is a rate per mailbox per month. The page does not mention a send or volume meter for the core product.

04
Other tools are priced apart
Inbox Insights has a test allowance priced at $0, $79 a month or $799 a year, and its page says the number of tests applies to an account, not each mailbox. Pulse is listed as free.

Savings are shown per band
The overview shows Save up to $2600 for 1 to 9 mailboxes, $5200 for 10 to 24 and $16600 for 25 to 99. It does not say how the figures are worked out, so we do not use them.

07
Inbox Insights counts tests per account
Its tiers run from 100 to 5,000 or more tests, and the page says the number of tests applies to an account, not each mailbox. A test is not priced per mailbox.

08
Billing follows the price description
The terms say subscription fees are paid upfront on a monthly basis unless the price description says otherwise, and that a subscription renews on the same conditions until you cancel.

What Folderly does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether the lower band rate applies to every mailbox or only the extra ones
- A cap on sends or on mailboxes per account
- What the minimum commitment covers
- Whether a band rate applies to every mailbox
- How the Save up to figures are calculated
- The length of a pilot or initial contract period
- Whether an extra mailbox can be added mid-month and how it is charged
Where the sources disagree
We report each version rather than pick one.
- Whether the band rate applies to every mailbox or to the extra mailboxes only is not stated. We assume every mailbox, as the page lists a price per mailbox by size band.
- Terms against pricing page: the terms say subscription fees are paid upfront monthly unless the price description says otherwise, and the pricing page labels the core rate Yearly. We cannot tell which billing a given quote follows.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Check how the bands apply
We assume the band rate applies to every mailbox, as the page lists a per-mailbox price for each size. Its page does not say so, so confirm it before you plan a budget.
Count the tools you need
Folderly's placement tests and alerts are separate products. Warmerly's placement test is built in but has limited accuracy.
Crossing 9 to 10 mailboxes
If the band rate applies to every mailbox, Folderly's total falls from $864 at 9 mailboxes to $720 at 10, a drop of $144. On Warmerly, 9 mailboxes need Growth at $49, the same price as 25.
Questions to put to a Folderly demo
Ask whether the band rate applies to every mailbox, what the minimum commitment is, whether billing is monthly or yearly, and what the pilot terms are. Our pages could not read any of these.
