02

03
Not a promise of volume
Each mailbox still sends inside its own daily limit, 30 a day for campaigns by default, so sends are bounded by mailboxes and ramp, not by a meter.

04
Growth is a mailbox plan
Growth allows 25 mailboxes with 25 active campaigns, 50,000 active prospects and 25,000 leads in a campaign, plus 25 placement tests a month.

05
Room at 25 mailboxes
25 mailboxes is the top of Growth. A 26th needs Agency at $179, so a fleet that will grow past 25 should price the step.

06
Per-mailbox daily sending
Each mailbox sends campaigns inside its own daily limit, 30 by default, so 25 mailboxes carry up to 750 campaign emails a day at the default (our arithmetic).

How Snov.io does it

03
Starter cannot do it
Starter at $39 has 3 warm-up slots, so 25 mailboxes does not fit.

04
Daily limits on Pro S
Pro S allows up to 100 warm-up emails a day per account, and the account sets its own goal inside that limit. The FAQ says to warm for at least 4 weeks on new mailboxes and 2 weeks on older ones.

Bulk handling
The warm-up page says unlimited accounts come with one dashboard and bulk settings from Pro S, under a Fair Use Policy.

06
Reply rate setting
You can set a reply rate in the warm-up settings, the share of your emails that get replies by the end of warm-up. No default or range is given.

07
Rules for campaigns beside warm-up
While campaigns run, keep warm-up at 10 to 20 emails a day, or pause campaigns during warm-up. Warm-up mail counts towards your email provider's own limits but not Snov.io's Messages per day setting.

Pro S also brings
5,000 credits, 25,000 recipients, 150 enrichment tokens a month and unlimited team members, so the $99 is not only for warm-up.

09
Placement tests for 25 mailboxes
Pro S includes more than 200 domain health and placement tests a month, which is 8 tests for each of 25 mailboxes (our arithmetic).

What Snov.io does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether 25 mailboxes on non-Gmail hosts would hit the Fair Use lowering
- Whether Fair Use ever applies at 25 accounts

Per month, billed monthly. Snov.io prices were read on snov.io/pricing on 21 October 2026; its card prices of $29.25 and $74.25 appear to be the annual rate (25% off). Snov.io's unlimited warm-up is subject to a Fair Use policy. Warmerly's LinkedIn add-on is charged per account on top of the plan.
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Our arithmetic
$99 minus $49 is $50 a month, or $600 a year at monthly list prices. Snov.io's plan also pays for credits and recipients, so check whether you would use them.
Price per mailbox
$49 over 25 mailboxes is $1.96 each and $99 over 25 is $3.96. The gap is $2 a mailbox a month, $600 a year in all. Our arithmetic from list prices.
What you get for the extra $50
Snov.io Pro S adds 5,000 credits and 25,000 recipients to the warm-up, and a CRM. If you would use them it is a good price. If you would not, you are paying $600 a year for a meter you never touch.
Both at their daily ceiling
25 Warmerly mailboxes at 50 a day warm-up is 1,250 warm-up emails a day at the top of the ramp. 25 Snov.io accounts at 100 a day is 2,500, but Snov.io's own advice is 30 to 50 a day, which is 750 to 1,250. Our arithmetic.
A fleet on non-Gmail hosts
If more than half of your 25 mailboxes are on hosts other than Gmail or Microsoft, Fair Use can lower slot counts. 25 is far below 500, so the practical effect is unclear, and the pages do not say.
Who it suits
