The Best Retell AI Alternative

Retell AI is a strong voice platform known for fast response times and realistic human-like talk. However, it is an enterprise tool built for advanced developers, specially in strict spaces needing SOC2 or HIPAA compliance. If you are a sales agency, real estate wholesaler, or B2B outreach team, starting with Retell is very hard. You cannot simply log in and start calling—you must build the software, connect data to your CRM, and manage the code.

Kolz Bulk solves this as the best Retell AI alternative for sales teams. We took the power of advanced AI and put it in an easy, no-code, "Excel-In, Excel-Out" platform. You do not need to build dashboards or hire engineers. With Kolz Bulk, you upload your standard CSV or Excel file, pick a ready-to-use sales template like Lead Qualification or Appointment Setting, and launch thousands of calls instantly.

Retell's pricing shows its focus on big businesses. Using their voice tools often costs between $0.13 to $0.31 per minute, depending on the specific AI and voice settings you pick. While this makes sense for highly complex customer service setups, it makes high-volume cold calling and finding new leads very expensive. Just 1,000 minutes on Retell can cost over $130.

As a better alternative, Kolz Bulk offers a very simple, flat rate of $0.03 per minute. There are no monthly payments, no base software fees, and no hidden AI costs. You pay only for exactly what you dial. Those same 1,000 minutes cost just $30 on Kolz Bulk, giving you a much better return on your money if your goal is getting more calls done.

Beyond the initial cost and setup, the output of the two platforms serves entirely different audiences. When an AI agent finishes a call on an API platform like Retell, it sends raw webhooks, JSON data, and audio logs that must be caught and routed by your own servers.

With Kolz Bulk, every campaign results in an Enriched Excel File that you can download directly from your dashboard. We automatically append new columns to your original uploaded list: Call Status, Lead Score (Hot/Warm/Cold), an AI-generated call summary, and a URL to the recording. This allows your human sales representatives to instantly filter for “Hot Leads” and start closing deals within minutes of the campaign finishing.
