How Warmerly does it
Warmerly, in detail.
Warmerly gives two ways in: a Free plan that never expires, and a 7-day trial of a paid plan. LinkedIn accounts sit outside both.
01
The Free plan has no card and no end date
Free is $0 with no card. It includes 1 mailbox, 1 active campaign, 500 leads per campaign, 500 active prospects and 100 campaign sends a month. Warmup is included and is not metered.

02
A sandbox mailbox from signup
Every signup gets a free sandbox mailbox that is already warming, separate from the one mailbox Free lets you connect.

03
The paid trial is 7 days and needs a card
Starter, Growth and Agency start with a 7-day trial. A card is required, nothing is charged until day 8, and you can cancel before then. The trial is once per workspace.

LinkedIn has no trial
A LinkedIn account at $19 a month is charged straight away, has no free trial and is not refunded. The Free plan includes no LinkedIn account.

05
Where Warmerly is behind
To try LinkedIn on Warmerly you must pay for an account first. If Dux-Soup's trial covers its whole product, it lets you try the LinkedIn side before paying; its pages do not say.

06
Cancelling a paid trial
If you cancel during the 7 days you pay nothing, because the first charge falls on day 8. The trial is once per workspace.

07
A sandbox mailbox shows warmup first
The free sandbox mailbox from signup is capped at 3 warmup sends a day, so it shows warmup working without using your connected mailbox.

What Dux-Soup does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- The length of the trial on its pricing page
- Whether a card is needed
- What is limited during the trial
- The content of its Refund Policy article, which its help centre lists
- The content of its Refund Policy article
- Whether the 14-day trial needs a card
- Whether the trial covers cloud as well as local
Where the sources disagree
We report each version rather than pick one.
- Most of its feature pages and its integrations page say 14 days; its pricing page, home page and get-stacked page state no length. On its agency page the 14-day button has no destination.

Per month. Dux-Soup prices are per seat and were read on dux-soup.com/pricing on 22 October 2026; the page shows a dollar sign and names no currency, and an earlier read from Sweden showed euro prices. Warmerly's email plans cover mailboxes and its LinkedIn add-on is 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 before you start
Dux-Soup's feature pages say 14 days, but its pricing and get-stacked pages state no card terms, so ask support or read the sign-up flow.
Warmerly's Free plan has no end date
One mailbox, capped sends and no card, so you can see warmup working before paying.
LinkedIn on Warmerly has no trial
The $19 account is charged at once, so test the email side first.
A 14-day trial against a 7-day trial
Fourteen days is double Warmerly's 7. Warmup takes 30 days to reach 50 a day, so a 7-day trial shows only the first week of the ramp, which starts at 4 a day and reaches 15 on day 7. A LinkedIn account has no Warmerly trial at all.
Test the email side first on Warmerly
The Free plan has no end date. A mailbox on Free warms for as long as you like, so you can watch day 14, at 25 a day, before paying anything.
Test LinkedIn first on Dux-Soup
If the trial covers local, you can install the desktop app and run a small campaign at the recommended 5 to 10 connection requests a day, which is 70 to 140 over a 14-day trial (our arithmetic).
Ask three questions before you start
Is a card needed, which plan does the trial include and what does the refund policy say about the first charge. None is answered on the pages we read.
