1. Email Warmup
Instantáneamente: Email warmup is included on every plan. The warmup network has over 1.5 million users, creating one of the largest peer-to-peer deliverability pools. Warmup runs automatically once you connect an account. You don’t need to configure anything.

Cálido: Warmup is the core focus. The Adeline AI engine sends up to 5,000 warmup emails per day on premium plans. You can customize warmup speed with Slow, Medium, or Fast modes. Slow takes 70 days but looks most natural. Fast takes less time but may raise flags.

💡 Test Result: Both tools delivered similar warmup results. New inboxes reached 85-87% inbox placement after 4 weeks. Warmy edged ahead slightly with 87% vs Instantly’s 85%.
2. Email Sending Capabilities
Instantáneamente: This is where Instantly shines. You can connect unlimited email accounts across all plans. The platform handles inbox rotation automatically. You can send thousands of cold emails daily by spreading volume across accounts. The Growth plan supports 5,000 emails and 1,000 contacts. Hypergrowth jumps to 100,000 emails and 25,000 contacts.

Cálido: Warmy does not send emails at all. It only warms up your inbox. You need a separate tool like Lemlist, Mailshake, or Instantly itself to actually send cold emails. This means you’ll pay for two tools instead of one.
3. Generación de clientes potenciales
Instantáneamente: The SuperSearch feature gives you access to 160 million+ verified B2B contacts. Filter by job title, industry, company size, location, and more. Leads come with verified email addresses. Credits are required but the database lives inside the platform.

Cálido: No lead generation features. You need to source leads from another tool like Apollo, Información de zoom, or Hunter.io. This adds another cost and another platform to your workflow.
4. Campaign Builder
Instantáneamente: The campaign builder is intuitive. Create email sequences with follow-ups. Use AI to generate subject lines and body copy. Add custom variables like first name, company, or any personalization field. Set up A/B tests to find winning messages (Hypergrowth and above).

Cálido: No campaign builder. Warmy focuses purely on warmup and deliverability testing. If you need to build email sequences, you’ll need a separate tool.
5. Funciones de IA
Instantáneamente: AI Reply Agent handles responses automatically for 5 credits per reply. AI writes email sequences and subject lines. The AI Prompts feature lets you personalize each email with custom AI-generated content. These features are available on mid-tier plans and above.

Cálido: The Adeline AI engine powers warmup automatización. It analyzes hundreds of parameters to adjust warmup pace. AI generates human-like warmup conversations. But AI features are limited to warmup only. There’s no AI for campaign creation.

6. Deliverability Testing
Instantáneamente: Run unlimited inbox placement tests. See where your emails land across major providers. The deliverability network includes blacklist monitoring. Light Speed plan adds SISR (Server & IP Sharding and Rotation) for dedicated IP pools.
Cálido: Inbox placement testing shows results across Gmail, Outlook, Yahoo, Google Workspace, and more. Each ESP includes 5 test accounts for 35 seed emails total. The inbox-wise placement report shows exactly where each test email lands. Testing is a strength here.

7. CRM and Pipeline Management
Instantáneamente: The built-in CRM tracks leads through your pipeline. Unibox consolidates replies from all connected accounts. Mark leads by status. Track deal stages. The CRM plans start at $47/month for Growth CRM and $97/month for Hyper CRM with calling and SMS.

Cálido: No CRM features. You’ll need to use a separate CRM like Fuerza de ventas, HubSpot, or Pipedrive. Warmy integrates with some tools via Zapier, but it doesn’t manage your sales pipeline.
8. Multi-Language Support
Instantáneamente: Primarily English-focused. The platform works for any language campaign, but warmup emails are mainly in English. This can be limiting for non-English markets where warmup relevance matters.
Cálido: Supports warmup in 30+ languages. This is a significant advantage for global campaigns. Your warmup emails match the language of your actual campaigns. This creates more natural inbox behavior.
⚠️ Warning: If you run campaigns in non-English languages, Warmy’s multi-language warmup may improve deliverability. English-only warmup can look unnatural in multilingual inboxes.
9. Integraciones
Instantáneamente: Connects with Gmail, Outlook, and SMTP providers. Slack and Webhook integrations on Hypergrowth. API access for custom integrations. Works with Zapier for connecting to other tools. The platform is designed to be all-in-one, reducing integration needs.

10. Pricing & Cost
| Comparación | Instantáneamente | Cálido |
|---|---|---|
| Entry Price | $30/mes | $49/month per inbox |
| 10 Inboxes Cost | $30/month (same price) | ~$400-500/month |
| 20 Inboxes Cost | $30/month (same price) | $1,000+/month |
| What’s Included | Send + Warmup + CRM | Warmup only |
| Annual Discount | ~20% off | ~15-20% off |
Instantáneamente: Flat monthly fee regardless of how many email accounts you connect. This is huge for scaling. The $30 Growth plan includes unlimited accounts. You could connect 50 inboxes and still pay $30/month for warmup and sending.
Cálido: Per-inbox pricing adds up fast. Warming 19 accounts can cost over $2,000/month. Volume discounts help, but the pricing model doesn’t scale well. You also need to pay for a separate sending tool.
💡 Test Result: For most users, Instantly is significantly cheaper. You get warmup + sending + leads for $30/month. Warmy charges $49/month just for warmup on ONE inbox.
