Best Warmy alternatives worth switching to in 2026
Warmy hid its 2026 pricing behind a demo call. Compare 4 real Warmy alternatives, Instantly, Smartlead, MailReach, and Lemwarm, with public pricing.
Warmy.io pulled its pricing page in 2026 and now routes every signup through a demo call. Warmy is a dedicated email warmup tool with spam-test scoring and deliverability monitoring, but sales-gated pricing, per-mailbox costs, and no built-in sending push teams elsewhere. The strongest Warmy alternatives in 2026 are Instantly for bundled warmup and sending, Smartlead for unlimited free warmup on every plan, and MailReach for transparent per-mailbox pricing.

At a glance
- Best overall: Instantly.ai bundles unlimited warmup with sending from $37/mo, so you stop paying twice.
- Best for agencies: Smartlead gives unlimited warmup on unlimited mailboxes from $32.50/mo.
- Best standalone specialist: MailReach, warmup only, from $20-25/mailbox/month with public pricing.
- Honest reframe: Warmy isn't broken. It's priced like enterprise software now.
Where Warmy actually loses to its alternatives
Warmy charges per mailbox and now hides that number behind a sales call, per MailReach's breakdown of Warmy's 2026 pricing. Every alternative below bundles warmup into a platform you already pay for, or keeps its per-mailbox price public. The real gap is transparency and bundling, not warmup quality.
- Warmy: spam-test scoring, no sending, pricing hidden behind a demo call.
- Instantly and Smartlead: warmup bundled free into a sending platform.
- MailReach and Lemwarm: standalone specialists with public per-mailbox pricing.
| Tool | Starting Price | Best For | Standout Feature |
|---|---|---|---|
| Warmy | Demo-gated (was $49/mo) | Dedicated spam-test scoring | Old tiers ran $49 to $429/mo by volume, per Findstack |
| Instantly.ai | $37/mo (annual) | 500+ emails/month senders | Unlimited warmup on every plan, no per-inbox fee |
| Smartlead | $32.50/mo (annual) | Agencies running 20+ mailboxes | Unlimited mailboxes and warmup on the Base plan |
| MailReach | $20-25/mailbox/mo | Founders with a few mailboxes | Public pricing, drops near $16 past 51 inboxes |
| Lemwarm | $24/inbox, free with Lemlist | Existing Lemlist Email Pro users | Free warmup bundled into an active subscription |
1. Instantly.ai
Instantly's Growth plan includes unlimited warmup at no extra charge, a real saving against Warmy's old rates, per Instantly's pricing page. The catch: Instantly runs several billed products under one login, and SDR teams often pay $200-400/mo after credits, per Landbase's 2026 breakdown.
Where it falls short: the headline price rarely matches the final invoice.
2. Smartlead
All four Smartlead plans include unlimited accounts and unlimited warmup, so an agency running 30 mailboxes pays the same $32.50/mo as one running 3, per Smartlead's pricing page.
Where it falls short: add-ons like SmartInfra and SmartProspect bill separately and add up fast.
3. MailReach
MailReach charges $25/mailbox/mo monthly or $20 annual, dropping toward $16 past 51 mailboxes, per MailReach's own pricing tiers. It's a dedicated warmup and spam-test tool, not a sender, so it slots in beside whatever you already use.
Where it falls short: cost still scales linearly with every mailbox, same as Warmy.
4. Lemwarm
Standalone Lemwarm runs $29/mo per inbox ($24 annual), but it's free with an active Lemlist subscription starting near $63/user/mo annual, per Lemlist's pricing page.
Where it falls short: Lemwarm alone, without Lemlist's sending tools, is a worse deal than most options here.
FAQ
Is Warmy.io worth it in 2026?
Warmy still works as a dedicated warmup tool, but it removed public pricing in 2026 and now requires a demo call, per Findstack's pricing breakdown. If you want a number upfront, MailReach or Smartlead are easier to budget against.
What is the cheapest Warmy alternative?
Smartlead's Base plan at $32.50/mo annual includes unlimited mailboxes and warmup, making it the cheapest option for teams running more than a couple of inboxes, per Smartlead's pricing page.
Does Instantly.ai include email warmup for free?
Yes. Every Instantly Outreach plan, from $37/mo annual, includes unlimited warmup with no separate per-inbox fee, per Instantly's pricing page.
Can I use Lemwarm without buying Lemlist?
Yes. Standalone Lemwarm starts at $29/mo per inbox ($24 annual), but it's free once you're on an active Lemlist subscription, per Lemlist's pricing page.
Picking a warmup tool fixes deliverability. It doesn't fix a mailbox that's empty because nobody's replying. That's the part Modern Inbound handles: sourcing, copy, and campaign execution built around inboxes that are already warm. See how pay-per-lead pricing works.
