Warmerly
Not a plan limit: each mailbox follows its own ramp, to 50 a day by day 30, with Gmail held to 40.
Mailivery
A shared daily cap: up to 200 on Starter, 800 on Professional, 2,500 on Business.
The short answer
Daily warm-up volume, in one look.
Warmerly does not sell a daily volume. Each mailbox warms by its own ramp, to 50 a day by day 30, with Gmail held to 40, and the ramp is cut on weekends and when health or placement slips. Mailivery sells a shared daily cap: up to 200 on Starter, 800 on Professional and 2,500 on Business, split across all your mailboxes. The two answer different questions. Mailivery lets you set the number and spend it where you like. Warmerly sets a schedule per mailbox and shows you the reason behind each day's figure. Last checked 22 October 2026.

How Warmerly does it
Warmerly, in detail.
No plan cap on warmup. Each mailbox has its own quota, set by how many days it has really sent, its provider and its health, with a small daily variation so the pattern is not flat.
01
A quota per mailbox
The daily quota moves between 4 a day at day 0, 8 at day 3, 15 at day 7, 25 at day 14, 35 at day 21 and 50 at day 30.

02
Provider caps
The quota is held to 40 a day on Gmail, 30 on Outlook and 25 on Zoho.

03
No monthly meter
Warmup is not counted against a monthly allowance on any plan.

04
The reason is named
The warmup page names the factor that limits today's quota for each mailbox.
Warmerly product, checked 21 October 2026
05
Days count only when the mailbox sent
The ramp follows the days a mailbox actually sent warmup mail, not calendar age. A mailbox that was paused for two weeks, or an old one that has only just switched warmup on, does not jump to late-ramp volume.

06
Weekends run lighter
On a Saturday or Sunday, judged in the mailbox's own time zone, the quota is multiplied by 0.6.
Warmerly product, checked 21 October 2026
07
Health and placement cut the quota
A health score under 50 multiplies the quota by 0.4 and under 70 by 0.75. A spam placement score of 10 or more multiplies it by 0.7, and 20 or more by 0.4. The lower of the two applies.
Warmerly product, checked 21 October 2026
08
A daily variation, not a flat line
The planner varies each mailbox's quota by up to 15% either way from day to day, so two mailboxes of the same age do not send identical counts.

09
A failing mailbox still gets one probe
If its last sends were refused, a mailbox is held to one warmup send a day instead of zero, so it can either recover or reach the point where we ask you to reconnect it.

No way to buy a higher warmup volume
Plans differ in mailbox count, not in warmup volume, so there is no tier to move up to for more warmup per mailbox.

A 1:1 rule of thumb
Its FAQ recommends matching warm-up volume to your cold sending volume at about 1 to 1.

06
A worked example on its own pricing FAQ
The FAQ says you can connect as many mailboxes as you like within the plan's daily limit, and gives 60 mailboxes at 10 warm-up emails each as an example. It uses a limit of 600 for Professional, while the plan table says 800.

07
A second example on the warm-up page
Its warm-up page says the Professional plan's 800 emails a day could be split across 80 inboxes at 10 a day, or 20 inboxes at 40 a day each.
mailivery.io/email-warm-up · read 22 October 2026
08
Why there is a per-inbox limit
The FAQ says the limit exists because the peer-to-peer network is built for responsible senders, not for spammers, and says it will review per-inbox limits each quarter. It gives the current limit as 250 emails a day for each inbox.
mailivery.io/pricing · read 22 October 2026
09
Match warm-up to cold sending
Its home page says a 1 to 1 ratio works well for cold mailboxes: 30 cold emails a day from a mailbox pairs with 30 warm-up emails a day from that mailbox. The pricing FAQ gives 50 and 50 as its example.

What Mailivery does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- How the shared volume is split between mailboxes by default
- What happens at the cap
- Whether unused daily volume carries over to the next day
- Whether the reply rate setting changes how much of the shared volume is spent
- Whether the plan table or the FAQ examples are the figures that apply, given the 600 and 800 difference
Where the sources disagree
We report each version rather than pick one.
- Professional and Business caps: the main table says 800 and 2,500 shared emails a day, while separate cards say 600 and 2,000.
- Per-inbox limit: the table shows 100 on Starter, while its FAQ says 250 for each inbox.
- Professional example: its pricing FAQ works an example on a limit of 600 a day, while its warm-up page works its example on 800.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Mailivery lets you steer
You choose volume and reply rate yourself, which suits teams that know what they want.
Warmerly has no pool to divide
Each mailbox follows the same published ramp, so adding a mailbox does not thin the others.
Five mailboxes at day 30
Five Warmerly mailboxes at the top of the ramp are each allowed up to 50 a day, so 250 in all, with the Gmail ones held to 40 each. Mailivery's Starter cap of 200 shared across five mailboxes comes to 40 each if you split it evenly. The two land close together, but Mailivery's figure is one you choose and Warmerly's is one the ramp sets.
Twenty-five mailboxes in their first week
At day 0 a Warmerly mailbox is allowed 4 a day, so 25 new mailboxes send up to 100 between them. On Mailivery's Professional plan that same 100 is a small slice of an 800 cap you could spend on other mailboxes. If most of your mailboxes are young, a shared cap goes further than a per-mailbox ramp.
Matching warm-up to a cold campaign
If one mailbox sends 40 cold emails a day, Mailivery's own 1 to 1 rule asks for 40 warm-up emails a day from it. Ten such mailboxes need 400 between them, which fits inside Professional's 800 but not Starter's 200. On Warmerly the same mailbox is capped by its ramp and provider, so a Gmail mailbox warms at no more than 40 whatever its cold volume.
The cap is a ceiling, not a target
Mailivery's examples use 10 emails a day per mailbox across 60 or 80 mailboxes. That is far below the 250 a day per-inbox limit, which tells you the shared cap, not the per-inbox limit, is what binds once you connect many mailboxes.
Who it suits

Mailivery
Mailivery is the better fit if
- You want to set volume and reply rate yourself

- You want to follow a 1 to 1 cold to warm-up ratio you set yourself
Questions
How many warm-up emails a day does Warmerly send?
Each mailbox follows a ramp from 4 a day on day 0 to 50 a day by day 30. Gmail is held to 40 a day and Outlook to 30.
How many does Mailivery send?
Up to 200 a day on Starter, 800 on Professional and 2,500 on Business, shared across your mailboxes, set by you.
Does Warmerly's warmup volume change by plan?
No. Every plan uses the same per-mailbox ramp. Plans differ in how many mailboxes you can connect, not in how much each one warms.
What lowers a Warmerly mailbox's quota?
The provider cap, weekends at 0.6 of a weekday, a health score under 70, and a spam placement score of 10 or more. The warmup page names the factor limiting today's number.
Does Mailivery tell you how to split the shared volume?
Its examples split it evenly, for instance 800 across 80 inboxes at 10 each. Its pages do not say how the split works by default or what happens at the cap.
