Warmboxとは何ですか？
Warmbox is an email warm-up service designed to increase your sender reputation and improve email deliverability.
When you send cold email campaigns from a new domain or inbox, email providers treat your account with suspicion.
Without a warm-up process, a lot of your emails land in the spam folder before your prospects ever see them.
Warmbox fixes this by connecting your inbox to a network of over 35,000 private inboxes that generate positive interactions — opens, replies, and spam removals — to build your email reputation automatically.
The platform supports multiple email providers including Gmail, Outlook, Yahoo Mail, and any custom SMTP connection.
ウォームボックス
Stop landing in the spam folder. Warmbox uses a network of 35,000+ private inboxes to build your inbox reputation automatically. Setup takes 2 minutes — no technical skills required.
ウォームボックスの価格
Here is what Warmbox costs in 2026. Plans are based on the number of inboxes you need to warm up.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| ソロ | 月額15ドル | Individuals warming up one cold email inbox |
| 起動する | 月額69ドル | Small teams with multiple email accounts |
| 成長 | 月額139ドル | Agencies and growing outreach teams |
| チーム | 価格についてはお問い合わせください | Large teams needing custom warm-up plans |
Pricing verified May 2026.
無料トライアル: Warmboxはフリーミアムモデルを採用しており、ユーザーは有料プランにアップグレードする前に、基本的な機能を無料で試用できる。
返金保証: Contact Warmbox support directly for refund policy details before purchasing a paid plan.
📌 注記： Warmbox’s Solo plan charges per inbox — costs scale as you add more email accounts. At the Growth tier ($139/month) you get multiple inboxes for agency-level outreach. The freemium option lets you test the warm-up process before committing.
⚠️ 警告： Warmbox does not provide email content checks. Spam trigger words in your email copy can still cause deliverability problems even after a full warm-up. Warmbox improves your sender reputation — it does not fix poor email writing.
Warmboxの主な利点
Here is what makes Warmbox worth considering for your email marketing efforts:
- 35,000以上のプライベート受信箱ネットワーク： Warmbox connects to over 35,000 private inboxes across various email providers. This generates positive interactions that look natural to email providers like Gmail and Outlook.
- AIを活用したウォーミングアップ： The platform interacts with your emails in a natural way — opening them, removing them from spam, and generating replies. This proactive approach builds your email reputation without manual effort.
- Detailed Analytics and Reports: Monitor your inbox reputation, spam score, and deliverability trends over time. Warmbox provides detailed reports so you can track exactly how your warm-up process is progressing.
- DNS配信可能性チェッカー： Monitor your DNS records and get alerted to configuration issues that could affect whether your emails reach the inbox or land in spam anymore.
- 複数のメールプロバイダーに対応： Works with Gmail, Outlook, Yahoo Mail, and any custom SMTP provider. Warm up accounts across various email providers from one dashboard.
- Email Templates for Warm-Up: Warmbox uses built-in email templates to generate realistic warm-up emails. These templates create natural-sounding conversations across your network of private inboxes.
- Automated Warm-Up Emails & Replies: The platform automatically sends warm-up emails, opens them, and generates replies to remove emails from spam folders. Higher reply rate signals during warm-up help build trust with email providers faster.
- More Leads Reach Inboxes: Once your warm-up is complete, more leads actually see your outreach. Warmbox’s proactive approach means fewer messages land in spam — directly improving your cold email reply rate over other tools that skip this step.
What Our Team Noticed
Our writer connected a cold email inbox to Warmbox and monitored the warm-up schedule for several days. Here is what stood out:
Warmboxの長所と短所
✅ メリット
- Fast setup with no learning curve — 2 minutes to get started
- 35,000+ private inbox network generates positive interactions automatically
- Supports various email providers including Gmail, Outlook, and custom SMTP
- Detailed analytics and reports on email reputation and spam score
- Freemium model lets users test basic features before upgrading
❌ デメリット
- Does not check email content for spam trigger words
- Per-inbox pricing adds up quickly when warming up multiple accounts
- Some users have reported mixed results — warm-up alone does not guarantee inbox placement
- Focuses only on warm-up activities — does not address broader email deliverability issues
💡 Warmbox Review Note: After completing the initial setup and proceeding to your first warm-up run, you may see a “verification successful — waiting” status as Warmbox confirms your inbox connection. This is normal. Some email providers display a Ray ID reference in their security logs when verifying new SMTP connections. Security checks like these ensure your domain is properly authenticated before warm-up emails begin.

1. Contact Database & Prospecting
アップリード: UpLead provides access to over 160 million business contacts across more than 200 countries. You can search by company name, job title, industry, mobile numbers, and 50+ other filters to find your next best customers. The database includes up-to-date contacts built for account-based marketing and targeted prospecting.
ウォームボックス: Warmbox does not provide any contact data or prospecting features. It is purely a deliverability tool. You bring the leads — Warmbox ensures your emails reach those contacts’ inboxes instead of landing in spam.
2. Email Verification & Data Accuracy
アップリード: UpLead verifies every email address in real time before you download it — delivering 95%+ data accuracy. This means fewer hard bounces and better deliverability for your cold email campaigns from the start. Users have praised this feature as a key reason UpLead enhances lead quality and boosts conversion rates.
ウォームボックス: Warmbox does not verify email addresses. It assumes your contact list is already clean. Pair Warmbox with a tool like UpLead to verify before you send — then use Warmbox to make sure those emails actually land in the inbox.
3. Email Warm-Up & Sender Reputation
アップリード: UpLead focuses strictly on data — it does not include email warm-up or inbox reputation features. Once you download verified contacts, you need a separate tool to manage your warm-up process and sender reputation before launching cold email campaigns.
ウォームボックス: This is Warmbox’s core strength. The platform uses 35,000+ private inboxes to generate positive interactions with your cold email inbox. It removes emails from spam, marks them important, and sends natural replies — gradually building your inbox reputation so your emails reach prospects, not the spam folder.
💡 プロのヒント: Email warm-up involves gradually increasing sending volume to build sender reputation. Without it, email providers can blacklist your domain. Warmbox automates this warm-up process entirely.
4. Intent Data & Account-Based Marketing
アップリード: UpLead’s intent data feature identifies companies actively researching products in your category. This helps you find in-market buyers at the exact moment they are ready to take action — making your prospecting far more targeted. Intent data is available on the Professional plan and helps identify consumption patterns that can grow businesses.
ウォームボックス: Warmbox does not provide intent data or account-based marketing features. The platform is focused entirely on email deliverability — it cannot help you identify which companies to target or when they are ready to buy.
5. CRM Integrations & Workflow Automation
アップリード: UpLead integrates with Salesforce, HubSpot, and other leading CRMs — plus Zapier to automate workflows with 1,500+ additional apps. Export leads directly into your existing sales workflow with one click. You can also use the API to build custom connection points with your tech stack.
ウォームボックス: Warmbox has limited integration options compared to UpLead. The platform is built around a single workflow — connecting your inbox and monitoring the warm-up. It does not natively integrate with leading CRMs or sales tools.
6. Deliverability Monitoring & Spam Score
アップリード: UpLead does not monitor inbox reputation or spam score. Its value is upstream — ensuring the contact data you use is accurate before you send. Clean data reduces bounce rates, which indirectly helps your sender reputation over time.
ウォームボックス: Warmbox provides detailed analytics and reports on your email reputation and deliverability score. The DNS deliverability checker flags configuration issues, and spam score monitoring shows how email providers view your domain — all updated in real time.
7. Technographic Data & Company Intelligence
アップリード: UpLead tracks over 16,000 technologies, letting you build contact lists based on the specific tools companies use. This is ideal for SaaS sales teams targeting companies using competitor products — or teams building account-based marketing lists around a specific tech stack.
ウォームボックス: Warmbox does not provide technographic data, company intelligence, or any form of contact enrichment. The platform’s scope is focused entirely on the email warm-up process and inbox health.
8. 使いやすさとセットアップ
アップリード: G2 reviewers describe UpLead as easy to navigate, with minimal training needed for sales teams to start building prospect lists. The interface is designed with a user-friendly approach so teams can search, filter, and import contact data without a steep learning curve.
ウォームボックス: Warmbox is designed to be intuitive and easy to set up — even for users seeking no technical skills. The setup process takes as little as 2 minutes. Its user-friendly approach means you connect your inbox and the warm-up schedule starts automatically with no manual work.
9. Chrome Extension & LinkedIn Prospecting
アップリード: UpLead’s Chrome extension enriches LinkedIn profiles and company websites with verified contact data while you ブラウズ. You can find phone numbers, mobile numbers, and real-time verified emails without leaving your current tab — making LinkedIn prospecting much faster.
ウォームボックス: Warmbox does not offer a Chrome extension or any LinkedIn integration. All features are managed through the web dashboard. The tool does not touch prospecting or contact discovery at any point in the workflow.
10. 価格設定とコスト
Here is the side-by-side pricing comparison:
| プランレベル | アップリード | ウォームボックス |
|---|---|---|
| エントリーレベル | 月額99ドル（170クレジット） | 月額15ドル（受信トレイ1つ） |
| 中級クラス | 月額199ドル（400クレジット） | 月額69ドル（初期費用） |
| 成長 | カスタム価格設定 | 月額139ドル（成長プラン） |
| 企業 | カスタム価格設定 | 価格についてはお問い合わせください |
アップリード: At $99/month, UpLead costs more upfront — but it replaces tools that cost three times as much. The cost includes real-time email verification, CRM integration, and access to millions of up-to-date contacts. G2 reviewers rate it #1 for best ROI among leading sales intelligence platforms.
ウォームボックス: At $15/month, Warmbox has one of the lowest entry points in the email warm-up service category. The cost grows as you add inboxes — so agencies warming up many accounts will see costs scale quickly toward the Growth or Team tier.
⚠️ 警告： These tools serve different parts of the same workflow — not the same need. Many teams use UpLead to find verified contact data, then use Warmbox to ensure their cold email campaigns actually reach the inbox. Consider whether you need one or both.

What Our Review Didn’t Cover
This comparison focused on individual sales teams and small-to-mid-sized businesses. We did not evaluate enterprise-level API usage, bulk data licensing, or how either tool performs for teams warming up hundreds of inboxes simultaneously. UpLead’s Professional plan includes custom pricing and 1,000+ credits — those details go beyond the scope of this review. If you are managing a large outbound team, test both tools directly before committing to a plan.

UpLead wins 4 out of 7 categories in this comparison.
最適な用途: B2B prospecting, real-time verified email data, account-based marketing, CRM-driven outbound sales
UpLead and Warmbox solve two different problems in the same cold email workflow.
UpLead gives you access to up-to-date contacts, real-time verified emails, mobile numbers, and intent data to find in-market buyers.
Warmbox ensures those emails actually reach the inbox — not the spam folder — by building your sender reputation through automated positive interactions.
If you can only choose one, UpLead is the stronger pick for most sales teams. Without verified contact data, even a perfectly warmed inbox has nothing to send.
But if your list is already clean and your emails keep landing in spam, Warmbox is exactly the tool you need next.
