Warmerly
A free plan with no card and no end date, or a 7-day trial on paid plans, which needs a card.
Mailivery
7-day free trial on its three plans; its pages do not say whether a card is needed. No free plan is listed.
The short answer
Free plan or trial, in one look.
Warmerly has a free plan with no card and no end date, and a 7-day trial on paid plans, which needs a card and charges nothing until day 8. Mailivery has a 7-day free trial on its three plans and no free plan. Its pages do not say whether a card is needed, what happens on day 8, or how to cancel, so those are the questions to ask before you start. If you cancel a Warmerly trial early, you move to the Free plan and nothing is deleted. Last checked 22 October 2026.

How Warmerly does it
Warmerly, in detail.
Two ways in: a free plan that never ends, and a 7-day trial on paid plans that takes a card and charges nothing until day 8. The terms are written down in the help centre.
01
Free is a plan, not a countdown
Free costs $0 and needs no card. It has no end date and includes 1 mailbox, 1 active campaign and 100 campaign sends a month.

02
The paid trial takes a card
Starter, Growth and Agency start with a 7-day trial. A card is needed to start it, nothing is charged until day 8, and you can cancel before then. It is once per workspace.

05
The first charge is on day 8
When a standard 7-day trial ends, the card is charged the day after the last trial day, and the plan carries on as a normal paid plan. Cancelling before then means no charge. The end date is shown in Settings, then Billing.

06
Cancelling ends the trial at once
Cancelling during a trial ends it straight away, not at its end date, and moves the workspace to the Free plan. Nothing is deleted and you can pick a plan again whenever you want.

07
One trial for each workspace
A workspace gets one trial. If it has already had one and you subscribe again, you are charged straight away and the card form says so before you confirm.

08
Monthly allowances are held at Starter levels
During a trial, allowances such as verifications, lookups, lead exports, placement tests and AI credits are held at Starter levels, even on a Growth or Agency trial. The mailbox and campaign limits of the plan you chose do apply.

09
You can skip the trial
In the workspace setup step you can choose to subscribe now instead of taking the trial, and the card is charged immediately.

- What happens when the trial ends and whether it renews
- Cancellation and refund terms
- Which plan the trial runs on, and whether you can pick
- Whether the trial limits volume, mailboxes or credits

Per month, billed monthly. Mailivery prices were read on mailivery.io/pricing on 21 October 2026; the page also shows two per-account cards ($80 and $140 a month) that it does not explain. Warmerly's email plans cover mailboxes; 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.
Read the trial terms first
Mailivery's pages leave out whether a card is needed and what happens after day 7, so ask or test with care.
Warmerly lets you stay free
If one mailbox is enough for now, the Free plan has no clock.
The cost of a mistake on day 8
On Warmerly a trial of Growth that you forget ends with a first charge on day 8 of $49, at the list price, unless you cancelled. The help centre says how to avoid it. On Mailivery the first charge could be $29, $79 or $199 depending on the plan, but its pages do not say when, so ask before you rely on the trial.
Test with a real mailbox, not a spare
A 7-day trial is shorter than the first two weeks of any warm-up ramp on either side: Mailivery shows a 14-day window and Warmerly a 30-day ramp. A trial will show you the dashboard and the controls. It will not show you finished warm-up, so judge the interface and the settings, not the final placement.
Free as a place to learn the product
Warmerly's Free plan has 1 mailbox and no clock, so you can connect one mailbox, watch the warmup page for a month and decide later. Mailivery has no equivalent, so a month of looking costs a month of Starter, $29 at list price.
Placement tests during the trial
On Mailivery, 10 credits on Starter at $0.25 each, if you bought them as a pack, would cost $2.50. On Warmerly a trial holds placement tests at Starter allowances, so a Growth trial does not give you the larger allowance early.

Questions
Does Mailivery need a card for the trial?
Its pages do not say. They show a 7-day trial button on each plan and give no terms.
Is Warmerly really free?
Yes. The Free plan has no card and no end date, with 1 mailbox and 100 campaign sends a month.
When is a Warmerly trial first charged?
The day after the last trial day, which is day 8 of a 7-day trial. Cancel before then and nothing is charged.
What happens to my data if I cancel a Warmerly trial?
The workspace moves to the Free plan and nothing is deleted. If it has more mailboxes or campaigns than Free allows, sending pauses until you reduce usage or pick a plan.
Does Mailivery's trial include everything?
Its pages say every feature is on every plan and the trial is offered on each, but they do not say whether the trial limits anything.
