1, 2 or 10 email addresses per account on its three listed plans; Agency is unlimited and quoted. Its FAQ says each paid user connects 1 mail account
The short answer
Mailboxes you can connect, in one look.
Warmerly's plan sets the number of mailboxes you bring: 1, 5, 25 or 100, on published prices of $19, $49 and $179 a month for the paid tiers. Mailshake's plan cards list 1, 2 or 10 email addresses per account at $29, $49 and $99 a month, and its Agency plan is unlimited with no price shown. Mailshake's FAQ describes it differently, as one mail account per paid user, so check how many users you would be billed for. On a cost per mailbox, Warmerly's Growth and Agency tiers work out lower on the listed prices, and Mailshake is ahead on an unlimited tier. Last checked 22 October 2026.

How Warmerly does it
Warmerly, in detail.
The plan sets how many mailboxes you can connect, and the monthly price divided by that number falls as you move up. Hosted mailboxes bought from Warmerly are counted separately and never use a plan slot.
01
Limits by plan
Free allows 1 mailbox, Starter 5, Growth 25 and Agency 100. These count mailboxes you bring yourself.
Warmerly product, checked 21 October 2026
02
Hosted mailboxes sit on their own meter
A mailbox that Warmerly hosts for you never uses a plan slot, so a 5-mailbox plan can still have a sixth hosted mailbox. It is billed per mailbox on the same subscription.

03
Warmup on every mailbox
Every mailbox the plan allows is warmed. Warmup is never metered.

Where Warmerly is behind
The top listed plan stops at 100 mailboxes and Max is quoted on a call. Mailshake lists unlimited email addresses on its Agency plan.

Price per mailbox on the plans
Starter is $19 for 5 mailboxes, about $3.80 each, Growth is $49 for 25, about $1.96 each, and Agency is $179 for 100, about $1.79 each. Annual billing is the monthly price times 10, two months free.

06
Hosted mailbox rates
A mailbox Warmerly hosts is $2.99 a month on Starter and Free, $1.99 on Growth and $0.99 on Agency, billed on the same subscription. There is no billing minimum on any tier.

07
Per-mailbox daily send default
A connected mailbox's campaign limit defaults to 30 a day, and the ramp and reputation brake can lower it. Sending itself is not metered, so the mailbox count is what bounds monthly volume. Five mailboxes at the default reach about 4,500 a month.

08
Free mailbox on every account
Each new account gets one free mailbox already warming up on a Warmerly-owned domain. It does not use a plan slot and, after 14 days and email verification, can send a small first campaign of up to 3 emails a day to verified addresses.

Gmail, Outlook, Zoho, Namecheap and custom SMTP and IMAP mailboxes can be connected, and each carries its own warmup status, ramp, health score and sending limits.

How Mailshake does it

One mail account per paid user
The FAQ says each paid user lets the team connect 1 mail account, and that you might pay for 3 users with only 1 person so that you can connect 3 mail accounts.

Which mail accounts work
Gmail, G Suite, Office 365, most Outlook and Exchange accounts, and most addresses that support SMTP and IMAP.

Agencies use client teams
The FAQ says to have a client create their own team so they are the billed party and add you as a user. You belong to as many teams as you like, and are not billed unless you have your own team.

What Mailshake does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- How the per-account address counts and the per-user rule work together
- A maximum for the Agency plan beyond the word unlimited
- What triggers a switch to another address
- A price or fair-use limit for the Agency plan's unlimited addresses
- Whether the ready-to-use mailboxes count toward the per-account address limit
- A per-mailbox daily sending default on the pricing page
Where the sources disagree
We report each version rather than pick one.
- The cards list addresses per account, while the FAQ says each paid user connects 1 mail account. We cannot tell from the page how the two combine.

Per month, monthly billing. Mailshake figures were read on mailshake.com/pricing on 21 October 2026 under its Monthly toggle; its Yearly toggle shows lower figures and the page does not say whether yearly is billed up front. Its FAQ says billing is based on users, so its total may differ from the card. Warmerly's LinkedIn accounts are 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.
Ask how users count
If you plan to pay for several Mailshake users just to connect more mail accounts, add that to the price you compare. Warmerly's mailbox count is on the plan itself.
Check the ceiling you will hit
Past 100 mailboxes Warmerly quotes on a call. Mailshake lists unlimited on Agency but shows no price.
Cost per sending address, monthly billing
Warmerly Starter is $19 / 5 = $3.80 a mailbox, Growth $49 / 25 = $1.96, Agency $179 / 100 = $1.79. Mailshake Starter is $29 / 1 = $29, Email Outreach $49 / 2 = $24.50 and Sales Engagement $99 / 10 = $9.90. Mailshake's plans include more than mailboxes, such as a dialer on the top tier, so this compares the address count only.
Ten sending addresses
On Warmerly, 10 mailboxes fit in Growth at $49 a month. On Mailshake, 10 addresses is Sales Engagement at $99, or $85 a month billed yearly. Alternatively two of its $12 domain add-ons give 10 ready-made mailboxes for $24 a month, though how they count against the per-account limit is not stated.
Monthly sending volume per address
Mailshake Starter lists 1,500 sends a month for its single address, about 50 a day over 30 days. Warmerly's default of 30 a day per mailbox across 5 Starter mailboxes is 150 a day, which is about 4,500 over 30 days. Both depend on warmup age and settings.
