05

Per mailbox price at 100

$179 over 100 mailboxes is $1.79 each at the top of Agency, and $149.17 a month annualised is $1.49 each. Our arithmetic from list prices.

Past 100

Max is agreed on a call with no published price, so a fleet above 100 should ask for a quote first.

Fair Use lowers the number

Active warm-up slots may be lowered to 500 on Pro S and Pro M, or 1,000 on Pro L and Ultra, if more than half of connected accounts use providers other than Gmail or Microsoft.

Fair Use is linked, not summarised

Daily limit on Pro S and above

Pro S allows 100 a day per account, Pro M 200, Pro L 500 and Ultra 1,000. The daily limit applies to each account separately.

05

Pro M and above for larger fleets

Pro M is $189, Pro L $369 and Ultra $738 a month. All list unlimited warm-up accounts, so the plan you pick depends on credits and recipients, not warm-up.

Fair Use figures

Active slots may be lowered to 500 on Pro S and Pro M, or 1,000 on Pro L and Ultra, when more than 50% of connected accounts use hosts other than Gmail or Microsoft.

07

Bulk management

The warm-up page says one dashboard and bulk settings manage unlimited accounts, from Pro S upwards.

Custom Ultra

Custom Ultra is for contact sales and adds bulk email account management, unlimited implementation manager services and top priority support, at 200,000 credits and up.

Fleet rules in the API

The API adds sender accounts over SMTP and IMAP only, with a daily limit of 1 to 1,200, so a fleet cannot be set up with Gmail or Microsoft sign-in by API.

In practice

What it means for you.

Our reading of the facts above. Not a promise, and not the only reasonable reading.

1

Where Snov.io is ahead

At 100 mailboxes the list price gap is $80 a month in Snov.io's favour. If most of your mailboxes are on Gmail or Microsoft, Fair Use is less likely to matter, and Snov.io is the cheaper way to warm a large fleet.

2

100 mailboxes at list price

Warmerly Agency is $179 a month, or $2,148 a year at monthly rates. Snov.io Pro S is $99, or $1,188. The gap is $960 a year in Snov.io's favour at monthly rates, or $899 with Warmerly on annual billing and Snov.io on annual. Our arithmetic.

3

What the $80 a month gap does not include

Warmerly Agency also adds client workspaces and an API with webhooks. Snov.io Pro S brings credits and recipients. The extra on each side is a different set of things, so compare what you would use.

4

At 200 mailboxes

Warmerly would need Max, priced on a call. Snov.io lists unlimited accounts from $99, but with Fair Use that could fall to 500 on Pro S and Pro M, 1,000 on Pro L and Ultra. 200 is under either figure, so it should not bite, though the policy text is not summarised.

5

Setting up a fleet

Snov.io lets you add sender accounts over SMTP and IMAP by API, with limits of 1 to 1,200 a day. Warmerly's Agency API covers mailboxes too, and its hosted mailboxes are a separate product.

Who it suits

Pick the one that fits.

Warmerly

Warmerly is the better fit if

You want a fixed 100-mailbox ceiling, client workspaces and the API in one plan
You manage mailboxes for several clients and want separate workspaces
You want the REST API and webhooks inside the plan

Snov.io

Snov.io is the better fit if

You warm 26 to 100 mailboxes and want the lowest list price
You want the lowest list price for a large warm-up fleet
You want a published price ladder up to 200,000 recipients

Questions

Is Snov.io cheaper for a large fleet?

On list price, yes: Pro S is $99 against Warmerly Agency at $179. Check its Fair Use policy first, which can lower active warm-up slots to 500 on Pro S.

What if my fleet is mostly Microsoft and Gmail?

Fair Use wording names other providers, so Gmail and Microsoft fleets are the least likely to be lowered.

What does a 150 mailbox fleet cost?

Warmerly would be Max, on a call. Snov.io would be Pro S at $99, subject to Fair Use.

Do client workspaces exist on Snov.io?

We did not find client workspaces on the pages we read. Warmerly Agency includes them.
