⚡ 快速结论：
- 定价： Smartlead’s Basic Plan starts at $32/month with 4 transparent tiers. Warmy lists five plans from $49/month but requires a sales call for exact pricing.
- 最适合： Smartlead for full cold email campaigns and cold outreach 自动化. Warmy for dedicated email warm-up and inbox placement improvement.
- 主要区别： Smartlead is an all-in-one cold email software with built-in warm-up, unlimited mailboxes, and a centralized master inbox. Warmy is a specialized deliverability tool with 30+ language support and AI-driven warm-up analytics.
- 我们的选择： Smartlead for most sales teams — it covers the full outreach cycle in one platform at a lower starting price.
Most sales teams pick their cold email tool based on price alone.
That’s a mistake — and it usually ends with emails landing in the spam folder.
Smartlead and Warmy both promise to fix your email deliverability.
But they solve that problem in very different ways.
One is a full cold email platform. The other is a specialized warm-up tool.
Choosing the wrong one means paying for features you don’t need — or missing ones you do.

⚠️ 警告： Some users report slow response times from Smartlead’s customer support, particularly on the Basic Plan.

Smartlead also does not provide real-time inbox updates, so you may need to manually refresh to see new emails.

- 无限邮箱： Every plan includes unlimited email accounts and unlimited sender accounts. You can scale cold email outreach without hitting artificial caps.

- Centralized master inbox keeps all email interactions in one place
- AI-powered email warm-up runs automatically to protect sender reputation

Warmy是什么？
Warmy is an email deliverability tool that focuses entirely on the warm-up process.
Its goal is simple: get your emails into the primary inbox, not the spam folder.
Warmy uses artificial intelligence to send warm-up emails through a real network of inboxes.
Those emails get opened, replied to, and marked as important — signaling to email providers that your domain is trustworthy.
One standout feature is multi-language warm-up support across 30+ languages.
This matters for teams running international cold outreach where the warm-up language needs to match the target audience’s domain environment.
Warmy also includes a Template Checker so you can test your email copy before sending — catching spam triggers before they hurt your sender reputation.
Rated 4.6/5 on Trustpilot, Warmy receives strong praise for its customer support and measurable improvements to inbox placement over time.
温暖
A dedicated email warm-up and deliverability tool with AI-powered warm-up in 30+ languages, template checking, and Adeline AI. Best for teams whose emails keep landing in the spam folder.
温暖定价
Warmy offers five pricing plans, but all require contacting sales to get exact figures.
| 计划 | 价格 | 最适合 |
|---|---|---|
| B2B 发送方 | 请联系我们获取报价 | B2B sales teams warming up 商业 domains |
| B2C 发送方 | 请联系我们获取报价 | B2C marketers improving consumer inbox placement |
| 定制方案 | 请联系我们获取报价 | Enterprises and agencies needing tailored warm-up volume |
Pricing verified May 2026. Based on AI Facts research, Warmy’s five plans are reported to range from approximately $49/month to $429/month — contact Warmy for confirmed pricing.
免费试用： Warmy offers a 7-day free trial so you can test warm-up features before committing.
退款保证： No public refund policy is listed — confirm terms with Warmy’s support before purchasing.
📌 笔记： Warmy’s plans differ primarily by the number of warm-up emails sent daily. Higher tiers allow greater daily volume, which matters for teams running aggressive domain warming across multiple accounts simultaneously.
⚠️ 警告： Warmy is not an overnight fix — most users need 2-4 weeks before seeing meaningful improvements in inbox placement. It is also not the cheapest option in the warm-up category. The lack of transparent pricing on the main plans makes budgeting difficult before a sales call.
保暖的主要好处
Here’s what makes Warmy a solid choice for email deliverability:
- 30+ Language Warm-Up: Warmy warms up your domain using emails in over 30 languages. This is rare among deliverability tools and critical for international outreach campaigns.
- Adeline AI Assistant: Warmy’s Adeline AI gives personalized warm-up recommendations based on your domain health, bounce rates, and inbox placement trends.
- 送达率测试： Built-in testing lets you check your domain’s current deliverability score before launching any email campaign. This shows which providers your emails reach.
- 模板检查器： Submit your email copy for analysis before sending. Warmy flags spam triggers that could push your messages into the spam folder.
- SPF记录生成器： Warmy includes a built-in SPF record generator to help with domain authentication — reducing the chance of being blacklisted.
- Google Postmaster 集成： Connect your Google Postmaster data directly to Warmy for a fuller picture of your domain’s health and sender reputation.

功能对比
Let’s compare Smartlead and Warmy across the features that matter most to a sales team or outreach-focused business.
Both tools tackle email deliverability — but from opposite ends of the problem.

1. 电子邮件热身
Smartlead： Smartlead’s warm-up is built into every plan at no extra cost. The AI mimics human-like conversations by sending, opening, and replying to emails automatically. It also applies unique IP rotating per campaign to reduce the risk of emails hitting spam filters. SmartDelivery and SmartAdjust tools monitor inbox placement in real time and adjust sending behavior to protect your sender reputation.
温暖： Warmy’s entire product is built around the warm-up process. It uses artificial intelligence to send warm-up emails across a real network of inboxes, supporting 30+ languages for international domain warming. The Adeline AI assistant analyzes your domain health and gives specific recommendations to improve inbox placement. Users consistently report measurable improvements in open rates and reduced bounce rates after using Warmy’s warm-up process.
💡 主要区别： Smartlead’s warm-up is a supporting feature inside a larger cold email platform. Warmy’s warm-up is the entire product — more advanced, but requires pairing with a separate tool for actual campaign sending.
2. 冷邮件营销活动
Smartlead： Smartlead is purpose-built for cold email campaigns. You can create multi-step sequences, personalize emails using variables and spintax, set up follow-up automation, and A/B test subject lines. The platform supports outreach across email, LinkedIn, SMS, and WhatsApp — all managed from the unified inbox. This makes it a true email automation tool for teams running outreach at scale.
温暖： Warmy does not run cold email campaigns. It is purely a deliverability and warm-up tool. If you want to send actual cold emails, you need to pair Warmy with a separate cold email software. This is worth knowing upfront — Warmy improves your domain’s health, but it does not manage your outreach efforts directly.
3. 收件箱管理
Smartlead： The centralized master inbox (also called the unibox) is one of Smartlead’s strongest features. It pulls replies, follow-ups, and conversions from all your email accounts into a single location. Your sales team can manage campaigns, respond to leads, and track the full pipeline without switching between multiple accounts. Note: the inbox does not update in real time — a manual refresh is needed to see new emails.
温暖： Warmy does not include an inbox management feature. Its email activity is limited to automated warm-up exchanges — none of which are real conversations with your prospects. For actual lead management, you need a dedicated cold email tool alongside Warmy.
4. 送达率工具
Smartlead： Smartlead includes SmartDelivery to monitor inbox placement and SmartAdjust to protect against low reply rates automatically. It also rotates IPs per campaign to reduce spam filter triggers. These are solid deliverability tools, but they are more focused on campaign-level protection than on deep domain health diagnostics.
温暖： Warmy’s deliverability tools go deeper. The built-in Deliverability Test checks your domain score across major email providers. The Template Checker flags content-level spam triggers before you send. Google Postmaster Integration gives you visibility into your domain’s health over time. For teams whose primary problem is getting emails out of the spam folder, Warmy’s toolkit is more specialized.
5. 集成和 API
Smartlead： Smartlead integrates with CRM systems and third-party platforms through APIs and webhooks. The custom CRM feature is available on the Pro Plan and above, letting you manage qualified leads and the sales pipeline within the platform. Native integrations cover popular tools that sales teams use for data enrichment and lead management.
温暖： Warmy integrates with Google Postmaster and connects to most major email providers for warm-up. Its integration library is narrower than Smartlead’s because it focuses on deliverability infrastructure rather than the broader sales workflow. Teams needing CRM sync or webhook automation will find Warmy’s options limited.
6. Personalized Outreach
Smartlead： Personalization is a core strength. Smartlead lets you insert variables (name, company, job titles) and use spintax to create variations of each email. This hyper personalization improves engagement rates and helps more messages reach the primary inbox rather than being caught by spam filters. AI-driven capabilities adjust messaging based on what’s driving the best results for each target audience.
温暖： Warmy’s personalization applies to warm-up templates — you can add custom warm-up topics and choose from different template styles to match your outreach emails. The Sequence Builder lets you define the pattern and timing of warm-up activity. This is not the same as campaign-level personalization, but it gives you some control over the warm-up process for your specific domain environment.
7. White Labeling & Agency Features
Smartlead： Smartlead offers custom white labelling with full rebranding options. Agencies can manage multiple clients under sub-accounts, each with their own settings and campaigns. Adding clients to the Pro Plan costs $29 per client per month. The Basic Plan does not include client management — it is designed for individual users and smaller businesses.
温暖： Warmy does not offer white labeling or agency-specific client management. The Custom Plan can be tailored for enterprise needs, but there’s no built-in framework for managing multiple clients under one branded dashboard. Agencies using Warmy typically manage each client account separately.
8. 易用性
Smartlead： G2 reviews and user feedback frequently describe Smartlead’s interface as unintuitive, particularly for beginners. The platform packs a large number of features into one dashboard, which means the learning curve is real. That said, once you understand the layout, the workflow becomes more natural. Active support is available on higher-tier plans, but response times on the Basic Plan are reported as slow.
温暖： Warmy also has a learning curve. Setting up warm-up schedules and interpreting Adeline AI recommendations takes time. G2 reviews highlight customer support as a strong point — Warmy’s team is described as responsive and helpful for smaller companies getting started.
9. 定价与成本
| 计划 | Smartlead | 温暖 |
|---|---|---|
| 入门级 | Basic Plan: $32/month | ~$49/month (contact for pricing) |
| 中级 | Pro Plan: $78/month | Mid plans: contact for pricing |
| 高音量 | Unlimited Smart: $144/month | Higher tiers: contact for pricing |
| Max / Enterprise | Unlimited Prime: $315/month | Up to ~$429/month (contact for pricing) |
| 免费试用 | 14天 | 7天 |
Smartlead： Smartlead’s pricing is fully transparent. The Basic Plan at $32/month is cost effective for small businesses starting their first cold email campaigns. All plans include unlimited email accounts and warm-up at no extra charge. The flexible pricing structure scales from solo senders all the way to large enterprise teams without requiring a sales call at any tier.
温暖： Warmy’s pricing starts higher and requires contact with a sales rep to get firm numbers. For teams comparing tools on a budget, this friction is a real drawback. The Starter plan is reported to start around $49/month but lacks advanced warm-up features — teams needing the full feature set will pay more. Warmy is particularly beneficial for enterprises sending high email volumes who need the deepest deliverability tools available.
不同场景
Your specific situation — budget, team size, outreach strategy — should drive this decision.
| 如果您需要…… | 选择 | 为什么 |
|---|---|---|
| 完整的冷邮件自动化流程 | Smartlead | Built-in campaigns + warm-up |
| Pure domain warm-up only | 温暖 | 专业交付能力 |
| 无限量电子邮件帐户 | Smartlead | 所有套餐均无邮箱数量限制 |
| 多语言热身 | 温暖 | 支持 30 多种语言 |
| 透明定价 | Smartlead | Public tiers, no sales call |
| 代理机构白标 | Smartlead | Full rebrand + sub-accounts |
| 深度交付能力测试 | 温暖 | Template checker + domain score |
💰 您的预算
Smartlead’s Basic Plan at $32/month is the most cost effective entry point for cold email software. Warmy’s transparent starting figure is around $49/month, but you’ll need a sales call to confirm — making budget planning harder for smaller companies.
🔌 您的技术栈
If your sales team already uses a CRM, Smartlead’s native integrations and API support make it easier to connect your data enrichment tool and manage campaigns from a single location. Warmy focuses on email provider connections rather than broad tech stack integration.
📝 您的推广策略
Running cold email campaigns and need everything in one tool? Smartlead is the right tool. Running outreach on another platform but struggling with spam folders and low inbox placement? Warmy is worth adding alongside your current cold email software.
🎓您的经验水平
Both platforms have a learning curve. Smartlead’s interface is described as unintuitive by beginners, but it offers more features once mastered. Warmy’s customer support is praised for helping smaller companies get up to speed — a meaningful advantage for first-time users of deliverability tools.
🆓 免费试用和演示
Smartlead gives you 14 days of full access — enough time to run a small cold email campaign and test deliverability. Warmy’s 7-day trial is shorter and limited in features. Either way, testing before buying is the right approach for both tools.
🛟 支持选项
Warmy receives notably positive reviews for customer support — helpful and responsive even for newer users. Smartlead’s active support is stronger on higher-tier plans; users on the Basic Plan report slower response times, which can be frustrating when deliverability issues need urgent attention.

我们的评测没有涵盖的内容
This comparison focused on individual users, small teams, and agency use cases. We did not evaluate enterprise-scale deployments with dedicated account managers or deeply custom onboarding workflows. Warmy’s pricing beyond the entry tiers was not independently verified — figures cited from AI Facts research should be confirmed directly with Warmy’s sales team. Our observations reflect the May 2026 versions of both tools; pricing and features may have changed since this article was published.
