Comparación de características
Apollo and Warmy serve completely different purposes in your sales stack.

1. Generación de clientes potenciales
Apolo: This is Apollo’s core strength. The platform includes a database of over 270 million B2B contacts and 60 million companies. You can filter by job title, industry, company size, location, and 200+ other data points. The Chrome extension lets you pull contact info from LinkedIn profiles and company websites instantáneamente.
Cálido: Warmy does not offer any lead generation features. It’s a specialized deliverability tool, not a prospecting platform. You’ll need a separate tool like Apollo, ZoomInfo, or Hunter to find contacts before using Warmy to warm up your sending domain.
2. Email Warm-Up
Apolo: Apollo does not include email warm-up features. If you’re starting cold outreach from a new domain, your emails may land in spam. Many Apollo users pair it with a dedicated warm-up tool to improve deliverability before launching campaigns.
Cálido: This is Warmy’s entire focus. The AI engine “Adeline” connects your inbox to a network of 20,000+ real email accounts. These accounts open your emails, reply to them, and mark them as important. This activity builds your sender reputation gradually over 2-3 weeks.
⚠️ Warning: Many sales teams use both tools together. Apollo finds the leads, Warmy ensures emails actually reach inboxes. They’re complementary, not competitive.
3. Email Sequences & Automation
Apolo: Apollo includes powerful email sequence automation. Create multi-touch campaigns with automatic follow-ups based on recipient behavior. A/B test subject lines, track open rates, and set custom delays between messages. The sequences integrate directly with Apollo’s database.
Cálido: Warmy includes a basic “Cold Email Sequencer” as a free tool, but it’s not its core function. The tool is designed for warm-up, not outreach automation. For serious email campaigns, you’ll need a dedicated platform like Apollo, Mailshake, or Lemlist.
4. Sales Dialer
Apolo: The platform includes a cloud-based dialer for making sales calls. Click-to-dial from any contact record, record calls automatically, and log everything to your CRM. The Organization plan adds an international dialer for global sales teams.
Cálido: Warmy does not include any calling features. It’s focused entirely on email deliverability. If phone outreach is part of your sales process, you’ll need a separate tool.
5. Deliverability Testing
Apolo: Apollo tracks email open rates and bounces, but doesn’t offer dedicated deliverability testing. You can see which emails were delivered, but not whether they landed in Primary inbox, Promotions, or Spam folders.
Cálido: Warmy includes detailed inbox placement testing. See exactly where your emails land across Gmail, Outlook, Yahoo, and other providers. The template checker analyzes your email content for spam triggers before you send.
6. CRM Integration
Apolo: Apollo integrates natively with Salesforce, HubSpot, Outreach, SalesLoft, and Marketo. Two-way sync keeps your data consistent across platforms. Custom API access is available on Organization plans for advanced integrations.
Cálido: Warmy offers basic integrations with platforms like Zapier. However, CRM integration isn’t really relevant here since Warmy doesn’t manage contacts or campaigns. It’s a background tool that runs independently of your sales workflow.
7. Data Accuracy
Apolo: User reviews report data accuracy around 65-70%, with email bounce rates of 15-25% on some segments. Mobile numbers tend to be less accurate than email addresses. Many teams add a third-party verification tool to clean Apollo data before sending.
Cálido: Data accuracy isn’t applicable here since Warmy doesn’t provide contact data. However, Warmy does include email verification to check your existing lists before warm-up. This helps identify invalid addresses that could hurt your sender reputation.
8. Facilidad de uso
Apolo: Apollo has a steeper learning curve due to its extensive feature set. New users often feel overwhelmed by the number of options. The interface is functional but feels cluttered at times. Expect 1-2 weeks to get comfortable with the platform.
Cálido: Warmy is simple to set up. Connect your email account via OAuth, adjust your warm-up settings, and let it run. The dashboard shows your deliverability score and progress clearly. Most users are up and running within 10 minutes.
9. Atención al cliente
Apolo: Support quality varies by plan. Free users get limited help. Paid plans include email and chat support. User reviews mention that billing questions often get routed between departments. Response times can be slow during busy periods.
Cálido: Customer support consistently receives high praise in reviews. Higher-tier plans include dedicated customer success managers. Users report quick responses via WhatsApp and email. The team provides hands-on help with deliverability issues.
10. Pricing & Cost
| Plan Level | Apolo | Cálido |
|---|---|---|
| Entry Level | $0 (Free) / $49/month | Contact us for pricing |
| Mid Tier | $79/mes | Contact us for pricing |
| Empresa | $119/mes | Contact us for pricing |
| Prueba gratuita | Free forever plan | 7-day trial |
Apolo: Apollo offers more value per dollar since it’s an all-in-one platform. However, the credit system creates unpredictable costs. Mobile number lookups cost 8 credits each, and credits expire monthly. Budget carefully to avoid overage charges.
Cálido: Warmy charges per inbox, which gets expensive when scaling. Warming 10 inboxes on the Negocio plan costs about $900/month. Volume discounts are available, but you’ll need to contact sales for custom pricing at scale.
💡 Test Result: Apollo’s transparent pricing at $49/month provides clear value for cold outreach. Warmy requires contacting sales for pricing, making it harder to budget upfront. If you already have leads and just need better deliverability, Warmy’s focused approach may still deliver faster results.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|
| Finding new leads | Apolo | 270M+ contact database built-in |
| Better inbox placement | Cálido | Specialized AI warm-up engine |
| Secuencias de correo electrónico | Apolo | Full automation included |
| Sales calling | Apolo | Cloud dialer built-in |
| Plataforma todo en uno | Apolo | Replaces multiple tools |
| Fast deliverability fix | Cálido | 90%+ inbox in 2-3 weeks |
💰 Your Budget
Apollo offers transparent pricing starting at $49/month with a free plan available. Warmy requires contacting sales for custom quotes, making budgeting harder. If you need lead generation and outreach in one platform, Apollo provides clearer value upfront.
🔌 Your Tech Stack
If you already have a lead source like LinkedIn Sales Navigator or Información de zoom, you might just need Warmy for deliverability. But if you’re building a sales stack from scratch, Apollo replaces multiple tools in one platform.
📝 Your Outreach Style
High-volume cold emailers often need both tools working together. Apollo finds and sequences leads while Warmy keeps your domain healthy. For low-volume, targeted outreach, Apollo alone may be enough.
🎓 Your Experience Level
Beginners should start with Apollo since it handles the entire sales workflow. Warmy requires you already understand cold email best practices. It fixes deliverability but won’t help you write better emails or target better leads.
🆓 Free Trials and Demos
Apollo’s free forever plan lets you test extensively before paying. Warmy offers a 7-day trial with full features. Test both tools with your actual workflow before committing to paid plans.
🛟 Support Options
Warmy consistently wins on customer support quality. Dedicated reps and quick WhatsApp responses stand out. Apollo’s support varies by plan and can be slow for billing questions.
