⚡ Quick Verdict:
- 価格: Warmbox starts at $15/mo vs Apollo at $49/mo for paid plans (both have free options)
- 最適な用途: Apollo for sales teams needing lead generation and sales engagement; Warmbox for cold email marketers focused on inbox deliverability
- 主な違い： Apollo is an all-in-one sales platform with 270M+ contacts; Warmbox specializes in email warm up and sender reputation
- Our pick: Apollo for most users — it handles lead generation, sales engagement, and deal management in one platform
Apollo and Warmbox solve different halves of the cold email problem.
Apollo finds the people you want to reach and helps you contact them. Warmbox makes sure those emails actually land in inboxes instead of spam folders.
The confusion happens because both tools touch email outreach.
But comparing them directly is like comparing a fishing rod to a cooler — they work together, but they do completely different jobs.
Sales professionals running cold email campaigns often need both: Apollo for lead intelligence and outreach sequences, Warmbox for protecting their sender reputation before emails go out.
This comparison breaks down which tool you actually need based on where you’re stuck in your sales process.
If you’re struggling to find potential leads with verified emails and phone numbers, that’s an Apollo problem.
If your emails keep landing in spam despite having good contact info, that’s a Warmbox problem.

機能比較
Apollo and Warmbox serve fundamentally different purposes in the sales process. Apollo is a sales intelligence and engagement platform, while Warmbox focuses exclusively on email warm up. This comparison looks at how each tool handles key features — and where their capabilities overlap or diverge completely.
| 特徴 | アポロ | ウォームボックス |
|---|---|---|
| 開始価格 | $49/month (Free plan available) | 月額15ドル |
| リードジェネレーション | ✅ 270M+ contact database | ❌ 利用できません |

| Chrome拡張機能 | ✅ LinkedIn and web | ❌ 利用できません |
| 最適な用途 | Lead generation and sales engagement | Email deliverability and warm up |
1. リードジェネレーション
アポロ： The Apollo platform provides access to a B2B database of over 270 million contacts and 60 million companies. Sales teams can use advanced search filters to find ideal buyers by job title, company information, industry, location, and hundreds of other data points. The platform includes data enrichment that pulls verified emails and phone numbers, helping sales professionals build targeted prospect lists without manual research on company websites and ソーシャルメディア プラットフォーム。
ウォームボックス: Warmbox does not offer lead generation capabilities. The platform focuses exclusively on email warm up and sender reputation management. If you need to find potential leads with contact info, you’ll need a separate tool like Apollo or another lead intelligence platform before using Warmbox to warm your sending domain.
2. メールのウォームアップ
アポロ： Apollo does not include built-in email warm up features. Users have reported that without proper warm up, some Apollo emails land in spam despite having accurate data. Sales teams running cold email campaigns through Apollo typically need to use a separate email warm up service to protect their sender reputation before launching outreach sequences.
ウォームボックス: This is Warmbox’s core function. The service uses a network of over 35,000 private inboxes to warm up your email account over 2-4 weeks. The warm up process involves automatically sending, opening, and replying to warm up emails — all actions that signal legitimacy to email providers like Gmail and Outlook. Warmbox offers multiple warm up options and custom warm up schedules based on your campaign timeline.
3. 営業活動
アポロ： Apollo provides full sales engagement capabilities including customizable sequences, automated follow-ups, and multi channel capabilities across email and phone. Sales professionals can create sequences with multiple touchpoints, schedule outreach based on prospect behavior, and use ai assisted email writing to クラフト personalized outreach at scale. The platform also includes a meetings scheduler that eliminates back-and-forth scheduling and integrates with Google Calendar.
ウォームボックス: Warmbox does not handle sales engagement or outreach. The tool warms your inbox before you send cold emails through other tools, but it doesn’t send campaigns, track responses, or manage follow-ups. You’ll need a separate sales engagement platform like Apollo, セールスハンディ, or Smartlead to actually run cold email campaigns after your inbox is warmed.
4. データ精度
アポロ： Apollo claims to provide accurate data with over 200 data points on each contact, including verified emails, phone numbers, job titles, and company information. However, user reviews show mixed experiences with data accuracy — some praise the most accurate data they’ve found, while others report outdated contacts and bounced emails. The Apollo Chrome extension helps by pulling fresh data from LinkedIn profiles, ensuring data accuracy when prospecting from live profiles.
ウォームボックス: Data accuracy isn’t relevant for Warmbox since it doesn’t provide contact data. The platform’s accuracy relates to its warm up process — specifically, how effectively it improves your sender reputation. Warmbox provides detailed reports on your spam score and inbox reputation, letting you monitor whether the warm up process is working.
5. Automation Tools
アポロ： Apollo’s automation tools cover the entire sales process. You can build sequences that intelligently automate outreach based on prospect actions, set up automated follow-ups on custom schedules, and trigger actions when leads hit certain engagement thresholds. The platform also automates deal management tasks, moving deals through your pipeline and alerting sales managers when action is needed.
ウォームボックス: Warmbox automates the email warm up process. The platform handles sending warm up emails, opening them, marking them as important, removing emails from spam, and generating replies — all without manual intervention. Once you connect your inbox, the automated interactions run on your warm up schedule until your sender reputation reaches optimal levels.
6. 分析とレポート
アポロ： Apollo provides detailed analytics on sales performance, email engagement, and team performance across your entire sales process. Sales managers can track open rates, reply rates, meeting bookings, and deal progression. The conversation intelligence features analyze call recordings, while the sales analytics dashboard shows pipeline health and forecasting data.
ウォームボックス: Warmbox offers detailed analytics focused specifically on email deliverability metrics. The dashboard shows your spam score, inbox placement rate, sender reputation trends, and how the warm up process is improving your deliverability over time. These detailed reports help you understand whether your emails reach inboxes or land in spam anymore.
7. 統合
アポロ： Apollo integrates with major CRM platforms including セールスフォース, HubSpot, and others to sync contact data and engagement history. The platform also connects with Google Calendar for meeting scheduling, LinkedIn for prospecting via the Chrome extension, and various other tools through API access. These integrations keep your sales processes connected across your entire tech stack.
ウォームボックス: Warmbox integrates primarily with email providers — Gmail, Outlook, Yahoo Mail, and various email providers. The setup connects your inbox to the warm up network, but Warmbox doesn’t integrate deeply with other tools like CRMs or sales platforms. For businesses using multiple sales tools, Warmbox operates as a standalone email warm up service that prepares your inbox for outreach done elsewhere.
8. 使いやすさ
アポロ： Apollo has a steeper learning curve due to its extensive feature set. Users report that the platform is powerful but can feel overwhelming for new users unfamiliar with sales engagement tools. Many find the user interface outdated compared to newer alternatives, though the advanced features justify the complexity for sales teams needing more advanced features.
ウォームボックス: Warmbox emphasizes its user friendly approach. The plug and play setup takes about 2 minutes with no technical skills required — you just connect your email account and choose a warm up schedule. The platform is designed to be intuitive even for users seeking their first email warm up service who have no prior experience with deliverability tools.
9. Intent Data
アポロ： Apollo provides intent data showing which companies are actively researching products like yours. This helps sales teams prioritize outreach efforts toward companies showing buying signals, focusing on relevant leads most likely to convert. The lead scoring system incorporates intent data alongside firmographic and engagement data to surface high quality leads.
ウォームボックス: Warmbox does not provide intent data or any lead intelligence features. The platform focuses solely on warming up your inbox — it has no visibility into prospect behavior or buying intent. For intent data, you’ll need a sales intelligence platform like Apollo or other tools designed for lead scoring and prioritization.
10. 価格設定とコスト
料金プランを並べて比較してみましょう。
| プランレベル | アポロ | ウォームボックス |
|---|---|---|
| 入場無料 | $0 (60 credits/month) | 月額15ドル（一人暮らしの場合） |
| Basic/Start-up | 月額49ドル | 月額69ドル |
| Professional/Growth | 月額79ドル | 月額139ドル |
| Enterprise/Team | 月額119ドル | 価格についてはお問い合わせください |
アポロ： Apollo’s pricing reflects its position as an all-in-one sales platform. The free plan with 60 monthly email credits works for solopreneurs testing the service. The Basic plan at $49/month suits growing sales teams needing more export credits and features. For sales teams needing conversation intelligence, deal management, and advanced analytics, the Professional and Organization plans justify the higher cost with their full feature set.
ウォームボックス: Warmbox offers a more affordable entry point at $15/month for the Solo plan, making it accessible for individual cold emailers and medium sized businesses watching their budget. The pricing scales with the number of inboxes you need to warm — start-up and growth plans add capacity for teams running multiple sending accounts. For enterprise needs with dozens of inboxes, the Team plan offers custom pricing.
⚠️ 警告： Don’t compare Apollo and Warmbox pricing directly — they solve different problems. Many sales teams use both: Apollo for lead generation and outreach ($49+/month) plus Warmbox for deliverability ($15+/month). Budget for both if you’re running cold email campaigns and need to find leads AND ensure your emails reach inboxes.

💰 あなたの予算
If you’re running cold email campaigns, expect to pay for both tools. Apollo handles the “who to contact” problem starting at $49/month (or free with limits), while Warmbox handles the “emails reaching inboxes” problem starting at $15/month. Tight budget? Start with Apollo’s free plan and add Warmbox’s Solo tier — that’s $15/month total to begin.
🔌 あなたの技術スタック
Apollo integrates deeply with CRMs like Salesforce and HubSpot, Google Calendar, and other sales tools through API access. Warmbox connects to email providers (Gmail, Outlook, Yahoo) but operates independently of your other sales tools. If CRM integration matters for your sales processes, Apollo is essential — Warmbox will run alongside whatever else you’re using.
📝 販売プロセス
If you already have a contact database and just need to ensure email deliverability, Warmbox alone might suffice. But if you’re building outbound from scratch — finding ideal buyers, enriching data, creating sequences, and tracking engagement — you need Apollo as your foundation. Warmbox becomes relevant once you have emails to send.
🎓 あなたの経験レベル
Warmbox is simpler — connect your inbox and it works. Apollo has a steeper learning curve because it does so much more. New sales professionals might find Apollo overwhelming at first, especially with advanced features like conversation intelligence and lead scoring. Warmbox requires almost no learning curve for users seeking a straightforward warm up service.
🆓 無料トライアルとデモ
Apollo offers a genuinely useful free plan with 60 monthly email credits — enough to test the platform on real campaigns. Warmbox offers a freemium model with basic features free before upgrading. Both let you test before committing to paid plans, so try both to see which addresses your specific bottleneck.
🛟 サポートオプション
Warmbox provides customer support through live chat and a detailed help center. Apollo offers support but some users report mixed experiences with response times. Both platforms have documentation, but Warmbox’s narrower focus means fewer things can go wrong. Apollo’s complexity means you may need more support to get the full value from advanced features.

What Our Review Didn’t Cover
This comparison focused on individual users and small-to-medium sales teams. We didn’t test enterprise-level features like Apollo’s Organization plan or Warmbox’s Team tier with custom pricing. Our observations are based on the April 2026 versions — features may have changed since then. If you’re managing 50+ sales reps, your needs around team collaboration, sales coaching, and advanced security features may differ from what we’ve covered.

最適な用途: Sales professionals who need lead generation, sales intelligence, and engagement tools in one platform
Apollo and Warmbox serve completely different purposes in the cold email workflow. Comparing them head-to-head is a bit unfair because they’re designed to solve different problems. Apollo is where you find people and reach out; Warmbox is how you ensure those messages actually land.
Apollo wins because it handles more of the sales process. With lead generation, data enrichment, sales engagement, deal management, and conversation intelligence all in one platform, sales teams can run their entire outbound operation from Apollo. The 270M+ contact database and advanced search filters help you find ideal buyers faster than manual research on company websites and social media platforms.
Warmbox excels at its narrow focus — email warm up and sender reputation. If your emails keep landing in spam despite having good contact info, Warmbox solves that specific problem better than most alternatives. The $15/month Solo plan makes it accessible for businesses watching their email marketing budget.
For most sales teams running cold email campaigns, the right answer is both tools working together. Use Apollo to find and contact prospects, add Warmbox to protect your sender reputation. The combined cost starts at $64/month (Apollo Basic + Warmbox Solo), which is reasonable for a complete cold outreach stack.
