The best Warmy alternative
Warmy is an email-deliverability service built around seed-inbox placement testing and reputation monitoring, pointed at whatever sender you already use. The best Warmy alternative is Autocloz: it runs the same multichannel cadences across email, calling and LinkedIn that Warmy is known for, then adds native SMS and WhatsApp and a free-forever CRM — with a built-in compliance gate and bring-your-own-key AI. The biggest difference is pricing: Autocloz includes 10–50 users on every paid plan, so you scale on per-channel volume instead of buying seats.
Why teams look for a Warmy alternative
Warmy measures where your mail lands. It cannot change the send rate that put it there, because it does not hold the send. Autocloz warms the same mailboxes it sends from, so a bad placement result and the pacing that caused it are governed by one set of limits instead of two tools negotiating across a gap.
Outreach is spread across too many tools
Warmy sequences none — a deliverability service, but SMS and WhatsApp aren't first-class and the CRM is an integration — so part of the journey always lives somewhere else.
Warmy vs Autocloz at a glance
On placement testing, Warmy gives you seed-inbox tests across the major providers; Autocloz gives you seed placement tests, plus the pacing that acts on the result. The full picture:
| Dimension | Warmy | Autocloz |
|---|---|---|
| Placement testing | Seed-inbox tests across the major providers | Seed placement tests, plus the pacing that acts on the result |
| When a test comes back bad | It is reported; you go and change the sender yourself | Per-mailbox hourly and daily caps and a bounce-rate auto-pause fire unattended |
| Works with any sender | Yes — points at your existing ESP or SMTP | Warms only the mailboxes it also sends from |
| Domain-level ramp | Warmup is per mailbox | 14-day sigmoid ramp at the domain level too (day 1 is about 10% of cap), skipped under roughly 50 sends a day so small workspaces are not throttled |
| Channels beyond email | None — a deliverability service | Email, calling, LinkedIn, SMS & WhatsApp in one login |
| Pricing shape | Per mailbox warmed, on top of your sender | Warmup included; 10–50 users on every paid plan |
Where Autocloz pulls ahead
Five channels in one cadence
Mix email, calling, LinkedIn, SMS and WhatsApp steps in a single sequence, with native SMS and WhatsApp rather than integrations. A lead can be emailed, called and messaged from one cadence, all logged to one timeline.
Free-forever CRM, no per-seat fee
The CRM core is free forever with 3 users and 100,000 contacts, and paid plans lift that to 10–50 users — so you can invite every rep, SDR and contractor without raising the bill. You only move to a paid plan to lift per-channel daily limits, mailboxes, contacts and verifications, so spend tracks volume, not headcount.
A compliance gate on every send
TCPA, DNC, quiet hours and 10DLC/WhatsApp opt-in are enforced at the dispatch gate across all channels, so a sequence can't reach a number or contact it shouldn't. Compliance is structural, not a checkbox you remember to tick.
One unified inbox for every channel
Email, LinkedIn, SMS, WhatsApp and call notes federate into a single Unibox, so a rep works one queue instead of switching between apps. AI-assisted replies are available with your own model key — no per-credit metering.
Who should switch from Warmy — and who shouldn’t
An honest read. The best switch is the one that fits your motion, so here’s where Autocloz is a clear win — and where Warmy or a specialist tool might still suit you better.
- Outbound sales teams that want email, calling, LinkedIn, SMS and WhatsApp on one timeline instead of stitching Warmy to four other tools
- Teams tired of per-seat pricing — every paid plan includes 10–50 users, so a growing team doesn't mean a growing bill
- Anyone who wants a real CRM under their outreach without paying for a second subscription
- SMBs and agencies that want enterprise-style multichannel cadences without enterprise seat minimums
- Large enterprise revenue orgs that depend on Warmy's deepest forecasting, RevOps and admin tooling and have the seat budget for it
How to switch from Warmy
- 1
Import your contacts and deals
Export your contacts, companies and pipeline from Warmy and bring them in by CSV or API. The free plan covers up to 100,000 contacts and 3 users, and any paid plan lifts that to unlimited, so the whole team and book of business land in one workspace.
- 2
Connect your mailboxes and channels
Connect your mailboxes (Google, Microsoft or SMTP) — built-in warmup and DMARC/DKIM/SPF mean you can move sending over safely — then add your carrier for calling, plus LinkedIn, SMS and WhatsApp. Every channel now lives under one login.
- 3
Rebuild your sequences as multichannel
Recreate your best-performing Warmy sequences in Autocloz and enrich them: drop in a call step, a LinkedIn touch or a WhatsApp follow-up where the old flow had only email. The compliance gate (TCPA, DNC, quiet hours, opt-in) checks every send for you.
- 4
Go live and watch one timeline
Enroll your leads and switch sending over. From here every email, call, LinkedIn message, SMS and WhatsApp writes to one lead timeline and federates into a single inbox — so the whole team sees the full story per prospect, with nothing left behind in Warmy.

What is the best free alternative to Warmy?
Autocloz is the strongest free alternative for outbound teams: a free-forever, AI-native CRM with email and calling (SMS and WhatsApp from Growth, LinkedIn on Scale) built into one login. Unlike most Warmy alternatives, the core CRM stays free for 3 users and 100,000 contacts, and every paid plan lifts the seat count to unlimited — you only pay to raise per-channel daily limits.
Is Autocloz cheaper than Warmy?
For most teams, yes. Autocloz charges no per-seat fee, so adding users within your plan's 10–50 seats never raises the bill, and the CRM is free forever for 3 users. Calling uses carrier pass-through (your own Telnyx, DIDLogic or FreJun rates, with no per-minute markup), so you scale on volume instead of seats or bundled minutes.
How do I migrate from Warmy to Autocloz?
Import your contacts, companies and deals by CSV or API, connect your mailboxes (Google, Microsoft or SMTP) and carrier, and rebuild your sequences as multichannel. You keep every channel — email, calling, LinkedIn, SMS and WhatsApp — on one lead timeline, and built-in warmup means you can move sending over without rebuilding your stack.
Does Autocloz do everything Warmy does?
For multichannel engagement, yes — Autocloz runs the email, calling and LinkedIn cadences Warmy is known for and adds native SMS and WhatsApp, a free CRM and a compliance gate. The main thing it doesn't chase is enterprise-only RevOps tooling, which is where the largest orgs may still prefer Warmy.
Is there a contract or per-seat fee?
No. Every paid Autocloz plan includes 10–50 users with no per-seat fee, and the CRM is free forever for 3 users — you can start without a card and invite the whole team. Paid plans simply raise per-channel daily limits, mailboxes, contacts and verifications, and you can change or cancel any time.
How long does it take to switch from Warmy?
Most teams are sending the same day. Importing contacts and connecting a mailbox takes minutes; rebuilding your best sequences as multichannel is the bulk of the work. Built-in warmup and deliverability tooling mean you can ramp sending safely rather than cutting over cold.
Can I keep Warmy and still send with Autocloz?
Yes, and for an evaluation that is the sensible order. Warmy points at a mailbox rather than at a platform, so you can leave it running on the mailboxes you have not migrated and let it grade Autocloz's sending independently. Nothing in Autocloz disconnects a mailbox from another service.
What does Warmy do that Autocloz does not?
It works against senders Autocloz does not replace. If your team is committed to an ESP, a marketing automation suite or a homegrown SMTP pipeline and that is not changing, Autocloz has nothing to attach to and a sender-agnostic deliverability service is the right shape. Autocloz's warmup is only useful on mailboxes Autocloz sends from.
Why does it matter that warmup shares the campaign ceiling?
Because warmup traffic and campaign traffic spend the same domain reputation, and a separate service cannot see your campaign volume. Run both at once and the domain can quietly exceed a safe daily rate while each tool believes it is behaving. In Autocloz warmup volume counts toward the same per-mailbox ceiling as campaigns, so the total is capped rather than the halves.
What is the 14-day domain ramp?
A new sending domain does not get its full daily allowance on day one even if fully-warmed mailboxes sit on it. The cap follows a sigmoid across 14 days — roughly 10% on day 1, full allowance by day 14 — because reputation filters react to a fresh domain producing hundreds of sends a day. It is deliberately skipped below about 50 sends a day, since a five-lead campaign was never the risk.
Does Autocloz grade my email copy for spam triggers?
No. Autocloz monitors authentication, placement and bounce behaviour, but it does not score your wording. If content-level diagnosis is what you are buying, that is a real gap and a dedicated deliverability tool covers it better.
