Sending is not metered on paid plans

What Warmbox does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- The currency: the page shows dollar signs and names no currency code
- Whether the prices include tax
- A refund or money-back statement
- Whether the yearly price is charged as one payment
- What happens to the price if you add an inbox mid-term
- A price for Team or for any size above 6 inboxes
Where the sources disagree
We report each version rather than pick one.
- The pricing page shows two sets of prices. The first set sits under a yearly billing label and the second under monthly billing; we read them that way.
- Warmbox's pricing FAQ says it usually takes 15 to 30 days of warming to see first results, while its help article says most users see the full benefit within 30 to 50 days. This matters to price because it sets how many months you pay before a result.
- The pricing page lists a plan as 1 member on the yearly set of prices and 1 team member on the monthly set. We read these as the same.

Per month, monthly billing. Warmbox shows a yearly price for each of its three plans ($15, $69 and $139) and no price for Team; read on warmbox.ai/pricing on 21 October 2026. Warmerly's email plans cover mailboxes; its LinkedIn add-on is charged per account on top.
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Count your inboxes first
At one inbox the two start at the same $19 a month. At five, Warmerly is $19 and Warmbox Growth ($159) covers only six.
Yearly billing matters on Warmbox
Its yearly prices are $15, $69 and $139. Compare like with like: monthly with monthly, yearly with yearly.
Compare yearly with yearly
On yearly billing Warmbox Solo is $15 a month and Warmerly Starter works out at about $15.83, so for one inbox Warmbox is 83 cents a month cheaper, and Warmerly's price covers 5 mailboxes.
Look at the cost of the sixth inbox
Warmbox Growth is the last priced step. If you plan to pass 6 inboxes, the price comes from a conversation, so you cannot budget it from the page.
Check what your team needs
Warmbox lists members by plan: 1, 3 and 6. Warmerly's plan table gives no seat count, so ask what your team needs before you decide on either.
Add the parts that sit outside the plan
On Warmerly, a LinkedIn account is $19 a month on top. If you only need email warm-up, you will not pay it.
Work out the free option first
One mailbox costs $0 on Warmerly Free, with capped campaign sends. If one mailbox is all you have, the question is whether the extra warm-up settings on Warmbox are worth $15 to $19 a month.
