The short answer
Pricing basis, in one look.
Warmerly is priced by how many mailboxes you connect, on four published plans from $0 to $179 a month. Mailshake is priced by the email addresses each plan allows per account: $29 for 1, $49 for 2 and $99 for 10 on monthly billing. On list prices, Warmerly costs less for a setup of several mailboxes. Mailshake's own FAQ says billing follows the number of users you buy, so confirm your total with it. Last checked 22 October 2026.

How Warmerly does it
Warmerly, in detail.
Four published plans, priced by mailboxes. Sending is not metered on paid plans, paying yearly costs 10 times the monthly price, and a 7-day trial with a card on file comes before the first charge on a paid plan. Free needs no card and does not expire.
01
Plans by mailbox count
Free is $0 for 1 mailbox. Starter is $19 a month for 5 mailboxes, Growth is $49 for 25 and Agency is $179 for 100. Max, for more than 100 mailboxes, is quoted on a call.

02
No monthly send meter on paid plans
Starter, Growth and Agency have no monthly send quota. Volume is bounded by the number of mailboxes and each mailbox's daily limit, 30 by default. Free is capped at 100 campaign sends a month.

Yearly is ten months
Paying yearly costs 10 times the monthly price, so two months are free.

04
Where Warmerly's pricing is behind
LinkedIn accounts are a separate $19 a month each, and no dialer is sold at any price. Mailshake's $49 plan already includes unlimited sends, which Warmerly meters through its mailbox count instead.

05
Price per mailbox at each step
Divide each plan's price by its mailbox allowance: Starter is $19 for 5, which is $3.80 a mailbox; Growth is $49 for 25, which is $1.96; Agency is $179 for 100, which is $1.79. The price per mailbox falls at each step.

A Free plan with no card
Free is a real plan at $0 with 1 mailbox, 1 active campaign and 500 active prospects. It needs no card, has no time limit and is not a trial.

07
A 7-day trial on paid plans
A paid plan normally starts with a 7-day trial. A card is required and nothing is charged during it. The first charge lands the day after the trial ends. The trial is available once per workspace.

08
Monthly allowances inside each plan
Starter includes 5,000 email verifications and 1,000 email lookups, Growth 25,000 and 10,000, and Agency 150,000 and 100,000. Mailshake's pricing page lists email verification as unlimited on every plan, so verification volume is one place Mailshake is ahead.

A Monthly and a Yearly toggle
Under the Yearly toggle the cards show $25, $45 and $85 a month. The page does not say in words whether yearly is paid up front.

03
Billing follows users
The FAQ says billing is paid by the team and based on how many users you purchase, and that each paid user lets the team connect 1 mail account. The cards describe addresses per account, so the two statements need checking against each other.

Two add-ons and an Agency plan
Data Finder is $19 a month ($17 under Yearly). Ready to Use Mailboxes is $12 a month ($11 under Yearly). The Agency plan lists unlimited email addresses and a Talk to Sales button, with no price.

No free trial

Mid-cycle changes are prorated
If you change subscription part way through a billing cycle, the costs are prorated, so you will have a pending charge or a credit on the account.

07
Cancelling and refunds
You can cancel at any time before the renewal date and will not be charged again, unless you owe prorated charges. The help article says the subscription is prepaid for the full cycle and that no refunds or pro-rated refunds are issued for cancellations. Access continues until the period ends.

What each plan includes beyond addresses
Starter and Email Outreach list 50 free Data Finder credits, and Sales Engagement lists 2,500. Every plan lists unlimited email warm-up, unlimited campaigns a month and unlimited email verification.

How agencies are billed
The FAQ recommends that an agency's client creates their own team, so the client is the billed party, and adds the agency as a user. You 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.
- A price for the Agency plan
- Whether the Yearly figures are billed up front
- Currency and tax treatment on the pricing page
- Whether the Yearly toggle is billed once for twelve months
- Whether there is any discount for annual payment beyond the card figures
- A published price for extra users
Where the sources disagree
We report each version rather than pick one.
- The cards list email addresses per account (1, 2 and 10), while the FAQ says billing is by users and each paid user connects 1 mail account. We show the cards and flag the FAQ.
- Mailshake's AI writer page says monthly plans start at $59 for email outreach, while its pricing page shows $49 for Email Outreach. We use the pricing page.
- Mailshake's refund article says it gives no refunds and that Mailshake is focused on support instead, while its pricing FAQ says concierge onboarding is offered. Both can be true, and we show both.

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.
Count mailboxes, then users
Write down how many sending mailboxes you need and how many people use the tool. Warmerly's bill follows the first number. Mailshake's page ties the bill to users and addresses, so give it both.
Compare the same month
Use monthly figures on both sides, or yearly on both. Warmerly's yearly price is 10 times monthly. Mailshake's yearly figures are shown per month under a toggle.
Five mailboxes on each side
Warmerly Starter is $19 a month for 5 mailboxes. Mailshake has no plan that lists 5 addresses: Email Outreach lists 2 for $49 and Sales Engagement lists 10 for $99. On list prices, five addresses on Mailshake therefore means $99, which is $80 more a month than $19, or $960 over twelve months.
One address, one year
A single sending address on Mailshake Starter is $29 a month, which is $348 over twelve months at monthly billing. One mailbox on Warmerly Free is $0 but allows 100 campaign sends a month. A paid Warmerly Starter year is $190 and covers 5 mailboxes.
Mailshake Email Outreach plus the mailbox add-on
$49 for the plan and $12 for the add-on is $61 a month if the two simply add together. The pages do not say how the add-on's 5 mailboxes count against the plan's 2 addresses, so confirm that before you rely on the figure.
Deciding without a trial
Warmerly lets you try a paid plan for 7 days and cancel before the first charge. Mailshake collects payment first and does not refund, so if you want to test it, ask its team for a demo or book the onboarding call before you buy.
Who it suits
