What Folderly does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A published price at 100 mailboxes
- Whether the band rate applies to every mailbox
- The minimum commitment
- A published total at any mailbox count
- Whether a per-mailbox rate applies to every mailbox in a band
- What a custom price at 100 or more depends on
- Any charge for onboarding or setup
Where the sources disagree
We report each version rather than pick one.
- Folderly's totals are calculated by us from its listed per-mailbox rates. Its pages do not give a total for any mailbox count. Working: 5 x 96 = 480, 9 x 96 = 864, 10 x 72 = 720, 24 x 72 = 1728, 25 x 56 = 1400.
Only what we could verify.

What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Treat the totals as calculated, not quoted
Folderly sells through a demo, so the price you are quoted may differ from the list rates we multiply.
Not like for like
Folderly's totals include its audit tools. Warmerly's include campaigns and no placement test with a seed list.
A 10-mailbox team
Folderly's list rates give 10 x $72 = $720 a month. Warmerly Growth is $49. The gap is $671 a month, before either side's quote or discounts.
A 50-mailbox agency
Folderly's list rates give 50 x $56 = $2,800 a month. Warmerly Agency is $179, a gap of $2,621, and Agency adds client workspaces and API access.
A year at Growth size
Warmerly Growth is $490 on annual billing or $588 paid monthly, a saving of $98. Folderly at 25 mailboxes is $16,800 over 12 months if the list rate holds.
Where Folderly's total dips
At 24 mailboxes the list total is $1,728 and at 25 it is $1,400. If you are at 22 or 23 mailboxes, adding to 25 can cost less than staying put, on the assumption that the band rate applies to every mailbox.
What you would still buy separately
Warmerly's totals include warmup, campaigns and a placement allowance. If you want a separate seed-list test tool on top, check each side's own price before adding them up.
Pick the one that fits.
