Warmbox
Set by inbox count: 1, 3 or 6, each with emails a day and team members listed; custom above 6.
The short answer
Pricing model, in one look.
Warmerly publishes a price up to 100 mailboxes and does not meter warmup. Warmbox also prices by how many inboxes you warm, and lists emails a day on each plan (50, 250, 500) and team members (1, 3, 6); above 6 inboxes it offers a custom Team plan with no price. Last checked 22 October 2026.

06
Capacity is live, not a total
Mailbox slots are a live count, so disconnecting a mailbox frees its slot at once and nothing resets on the 1st.

What happens at the limit
Connecting a mailbox beyond your plan is refused with an explanation. Nothing is charged and nothing is deleted.

08
Downgrades get a grace period
A workspace that ends up over its plan, for example after a downgrade, gets a grace period with a countdown banner. Warmup and sending pause only if it is still over when it ends.

Five allowances reset monthly
Verifications, lookups, exports, placement tests and AI credits reset on the 1st and do not roll over. A failed action is not charged.

What Warmbox does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether the emails a day figure is per inbox or for the whole plan
- What happens when the daily figure is reached
- The price of the Team plan
- Whether unused inboxes can be removed to lower the price
- Whether yearly plans can be refunded part-way
- How a plan behaves when you go over its daily emails figure
Where the sources disagree
We report each version rather than pick one.
- Warmbox's pricing page lists emails a day per plan, while its help article on sending limits says the daily maximum depends on the inbox provider and the plan, with no figures. We could not tell whether the figure is per inbox.
- The pricing page's own FAQ gives a time to first results of 15 to 30 days, while the help-centre article says 30 to 50 days, up to 90. We show both rather than choose one.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Check what the daily figure means
Warmbox lists 500 emails a day on Growth, which has 6 inboxes. Its page does not say whether that is per inbox or shared, so ask before you plan around it.
Plan for the step
On Warmbox the next size up from 6 inboxes is a conversation. On Warmerly it is a published price until 100 mailboxes.
Ask what the daily figure counts
Warmbox does not say whether 500 a day on Growth is per inbox or across all 6. Divided across 6 it would be about 83 each, and if per inbox it would be 500 each. Its recipe articles suggest 40 emails a day for a first campaign, so the difference matters.
Plan for allowances on Warmerly
Warmup is not metered, but verification, placement tests and AI credits are. Check the monthly figures for the plan you pick before you rely on them.
Think about who needs a seat
Warmbox ties members to plan size. If you have a large team and few inboxes, that is a cost you pay for on Warmbox; ask Warmerly what your team needs, because its plan table gives no seat count.
Watch for the step above the top plan
Warmbox's custom Team plan and Warmerly's custom Max plan both start where the listed prices stop: 6 inboxes on Warmbox, 100 mailboxes on Warmerly.
