The short answer
Free plan and trial, in one look.
Both have a free plan and a trial of the paid plans. Warmerly Free needs no card and covers 1 mailbox with 100 campaign sends a month; the paid trial is 7 days and needs a card. Apollo Free allows 1 mailbox per user, 250 emails a day and 2 sequences per team, on Gmail only, and its trial is 14 days on Basic or Professional. Apollo is ahead on free sending and trial length. Last checked 22 October 2026.

Warmerly, in detail.
A free plan that does not expire, and a short card-first trial on paid plans.
01
Free has no card and no end date
Free is $0. It includes 1 mailbox, 1 active campaign, 500 leads per campaign, 500 active prospects and 100 campaign sends a month. Warmup is included and not metered.

02
A sandbox mailbox from signup

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

04
Longer trials for two groups
A visitor who claims the website's 30-day offer gets 30 days. An approved Warmerly for Startups application gets 90 days of Agency.

05
What else Free includes
Free also includes 250 email verifications, 50 email lookups, 50 LinkedIn lookups, 100 lead exports and 3 placement tests a month. It has no AI credits and no API access.

06
Free is not a countdown
The docs call Free a real plan: no card, no expiry. The 100 campaign sends a month are described there as an abuse guard, not a trial clock.

07
What a paid trial gives you
During a trial the monthly allowances are Starter's whatever tier you trial, while the mailbox and campaign ceilings are the trialled tier's own. Warmerly for Startups is the exception and gets full Agency allowances.
Warmerly product, checked 21 October 2026
08
A 30-day claim has a window
The 30-day offer is honoured only if the visitor claims it within 14 days of creating the account, and it is used once. A Startups grant ignores the offer and the two never stack.

Where Warmerly is behind
Warmerly's trial is shorter than Apollo's, and its free plan sends far less.

How Apollo.io does it
Apollo.io, in detail.
A free plan with real sending, and a 14-day trial of two paid plans with limits during the trial.
01
Free plan limits
Free is $0 with 1 mailbox per user, 250 emails a day, 2 sequences per team and 900 credits per seat per year. The FAQ says that on free plans you can connect Gmail accounts only.

14-day trial of Basic or Professional
Basic and Professional show a Start 14-day trial button. The help article says a team on a free plan can start a 14-day trial of either, and that Apollo does not offer a trial of Organization.

Once only
The help article says you can activate a free trial of Apollo only once, and that upgrading during the 14 days ends the trial at once, with any remaining days and trial credits lost.

Trial limits
The help article lists a record selection limit of 25, access to 20 phone numbers for the whole trial whatever credits remain, and 60 minutes of calls with 10 minutes at most per call. Upgrading removes the phone and dialling cap.

Switching plans mid-trial
You can try the other plan during the trial from Settings, Billing and credits, Plan overview. Apollo keeps the original number of days: switching on day 7 leaves 7 days. The dialer is on the Professional trial only.

Going back down
Moving from a paid plan to Free limits you to one seat and you lose the other seats ten days after the downgrade. Downgrades take effect at once and the help article says no refund is given for unused time.

What Apollo.io does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether a card is needed to start the 14-day trial
- Whether unused monthly Free credits carry over within the year
- How Apollo defines 'active use' for the one hundred days on Free
Where the sources disagree
We report each version rather than pick one.
- Apollo's pricing FAQ says a trial moves you to a free Starter plan, while the price cards name the free plan Free. We treat them as the same plan.
- Apollo's pricing FAQ says free plans connect Gmail accounts only, while its rendered compare table lists Gmail & Microsoft for the Free plan. We cannot say which is current.
- Apollo's pricing FAQ names the plans Free, Basic, Professional and Custom and says API access is on Custom plans, while the price cards show Organization at $119 a seat with a minimum of 3 seats and the table lists API Enrichment on Basic and above.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Try the thing you will pay for
Warmerly Free is enough to connect a mailbox, watch warmup and run a small campaign. Apollo Free is enough to search a little data and send up to 250 a day on Gmail.
A longer clock is real value
Fourteen days is long enough to see a few days of warmup movement. Seven days is short, which is why Warmerly's free plan has no end date.
What 75 trial credits buy
At 1 credit per email and 8 per phone number, 75 credits is 75 emails or 9 phone numbers (72 credits). The trial's own cap of 20 phone numbers is therefore not the first limit you meet.
Free credits by the month
900 credits a year, granted monthly, is 75 a month on average. One linked mailbox's warmup costs 200 credits per 30 days on a free plan, by the warmup help article, which is more than a month's share.
Trial length against a warmup ramp
Warmerly's warmup ramp reaches 15 a day on day 7 and 50 on day 30. A 7-day trial ends where the ramp is at 15, a 14-day trial at 25, and a 30-day trial at the full 50. Apollo's warmup help article recommends at least a two-week warmup.
Mailboxes in a team trial
Warmerly's Free plan covers 1 mailbox, and a Starter trial covers up to 5, so a team of three with one mailbox each can all be connected in one workspace. Apollo's Free and Basic list 1 mailbox per user, so each person connects their own.
Who it suits
Pick the one that fits.
Warmerly
Warmerly is the better fit if
- You want a free plan with no card and no end date
- You want to see warmup working before paying

Apollo.io
Apollo.io is the better fit if
- You want more free sending
- You want a 14-day trial of a paid plan with the dialer on Professional
