Funktionsvergleich
Let’s break down how these platforms compare across 8 critical features.
This side-by-side analysis reveals which tool fits your specific needs.
I tested both platforms for four weeks using identical prospect lists.
The results surprised me in several areas.
Klenty excels at multi-channel selling where multiple touchpoints matter.
Instantly dominates when pure email volume is the priority.
| Besonderheit | Sofort | Klenty |
|---|---|---|
| Startpreis | $30/month (flat) | 50 $/Nutzer/Monat |
| Email Accounts | Unbegrenzt | Limited by plan |
| Multi-Channel Outreach | ❌ Email only | ✅ Email, Phone, LinkedIn, SMS, WhatsApp |
| Built-in Dialer | ❌ | ✅ Power & Parallel Dialer |

| Am besten geeignet für | High-volume cold email | Multi-channel sales teams |
1. Email Outreach & Volume
Email volume matters for cold outreach at scale.
More sends mean more opportunities to connect with prospects.
But raw numbers aren’t everything.
Quality and deliverability determine actual results.
Klenty: Allows up to 500 emails per day on the Startup plan. The platform focuses on quality over quantity with behavior-triggered sequences. Email personalization uses AI templates that adapt based on prospect engagement signals. Higher tiers unlock increased sending limits for growing teams.
Sofort: Sends up to 500,000 emails monthly on the Light Speed plan. Unlimited email accounts let you spread volume across dozens of domains. The inbox rotation feature automatically distributes sends to protect sender reputation.
⚠️ Warning: High volume doesn’t guarantee results. Instantly users report best results with 30 emails per inbox per day. Going higher risks deliverability issues even with warmup.
2. Multi-Channel-Kommunikation
Modern B2B buyers don’t respond to email alone.
They check LinkedIn, answer phone calls, and read Text Nachrichten.
Multi-channel outreach increases reply rates by reaching prospects where they’re active.
Klenty: Runs cadences across five channels: email, phone, LinkedIn, SMS, and WhatsApp. LinkedIn automation sends connection requests and messages automatically. Multi-step playbooks adapt based on which channel gets engagement. This unified approach prevents tool sprawl.
Sofort: Focuses exclusively on email outreach. No phone dialer, LinkedIn automation, or SMS capabilities exist. If you need multi-channel sequences, you’ll need additional tools alongside Instantly.
3. E-Mail-Zustellbarkeit
Deliverability determines whether your emails land in inboxes or spam folders.
Without proper warmup and monitoring, your campaigns fail before prospects see them.
Both platforms offer warmup features, but the approaches differ significantly.
Klenty: The Deliverability Suite monitors domain health and provides inbox placement insights. Email verification prevents bounces before sending. The warmup network is smaller than competitors but integrates natively with the platform.
Sofort: Operates the largest warmup network in the industry with 4.2 million accounts. Automated warmup runs on every connected inbox. SISR (Server & IP Sharding and Rotation) on Light Speed rotates away from underperforming IPs.
4. CRM Integration
Klenty: Offers native bidirectional sync with Salesforce, HubSpot, Pipedrive, Zoho, and Microsoft Dynamics. Activities log automatically without manual entry. The CRM Acceleration framework ensures your pipeline stays current.
Sofort: Relies on API connections and Zapier for CRM integration. No native sync with major CRMs exists on any plan. Teams must build custom workflows to push data between Instantly and their CRM.
⚠️ Warning: If your team lives in Salesforce or HubSpot, Instantly’s lack of native integration creates significant friction. Manual syncing wastes SDR time.
5. Phone Dialer & Calling
Klenty: Includes a built-in Power Dialer and AI Parallel Dialer that calls up to five prospects simultaneously. Conversation intelligence records calls and generates insights. Sales managers can coach reps based on call analytics.
Sofort: Has no phone dialer or calling capabilities. The platform focuses entirely on email. Sales teams that need calling must purchase a separate tool like Aircall or RingCentral.
6. AI Features & Automation
Klenty: Deploys 6 AI agents including Action AI that generates follow-up tasks from call conversations. AI identifies buying signals across touchpoints. Personalization goes beyond mail merge to context-aware messaging.
Sofort: Uses AI for email copy generation, subject lines, and sequence creation. The AI Reply Agent automates responses with intent categorization. Over 100 community templates provide starting points for campaigns.
7. Lead Generation Database
Klenty: ProspectIQ provides access to 440 million B2B contacts globally. You can enrich existing CRM records with professional and company details. Data integrates directly into your sales workflows without exports.
Sofort: SuperSearch offers 450 million B2B contacts with waterfall verification across multiple providers. Credits are purchased separately starting at $47/month. The database is slightly larger than Klenty’s offering.
8. Pricing & Cost
| Team Size | Instantly Cost | Klenty Cost |
|---|---|---|
| 1 User | 30 $/Monat | 50 $/Monat |
| 3 Users | 30 $/Monat | 150 $/Monat |
| 5 Users | 77,60 €/Monat | 250 $/Monat |
| 10 Users | 77,60 €/Monat | 500 US-Dollar/Monat |
Klenty: Per-user pricing makes sense for small teams but scales up fast. A 5-person SDR team pays $250-$495/month depending on plan tier. Enterprise features require the Plus plan at $99/user.
Sofort: Flat monthly pricing stays the same regardless of team size. The $77.60 Hypergrowth plan covers unlimited users. Agencies especially benefit from this model when managing multiple client accounts.
💡 Test Result: For a 5-person SDR team, Klenty costs 2.5x more than Instantly monthly. But Klenty’s multi-channel features may reduce the need for other tools, balancing total stack costs.
