Prospi

Prospi is an all-in-one AI cold email platform built to replace a separate lead database, sending tool, warmup service, and inbox manager with a single system. It pairs a database of more than 325 million verified contacts with an AI agent that researches each prospect and writes personalized opening lines, then sends through inboxes the platform can provision and warm automatically. The product is aimed at B2B companies, agencies, consultants, and sales teams that run outbound without a dedicated SDR function. Prospi's stated positioning is that it measures positive replies rather than total replies, on the argument that standard reply-rate metrics count rejections and opt-outs as wins. The company states that more than 300 B2B companies use the platform.

Features

     
• 325M+ Verified Lead Database: Contact and company records can be filtered by job title, industry, company size, location, revenue, and technology stack, alongside a separate ecommerce database of over 187 million leads.
     
• AI Personalization Agent: The AI scrapes each prospect's website and public data to write unique opening lines rather than filling variables into a generic template.
     
• Built-In Deliverability Engine: Warmup, SPF, DKIM and DMARC configuration, inbox rotation, and deliverability monitoring run automatically, with the company reporting inbox placement above 96 percent.
     
• In-App Inbox Provisioning: Domains and Google Workspace inboxes can be purchased inside the platform at $3.50 per account, with DNS handled automatically.
     
• Smart Inbox and Reply Sorting: Replies are categorized automatically as interested, not interested, meeting-ready, or out of office, with suggested responses, calendar scheduling, and mobile push notifications on positive replies.
     
• Agency Whitelabel: Agencies can run the platform under their own brand, logo, colors, and domain, with unlimited workspaces and no per-seat fees.
   

Pricing

Prospi runs a single plan priced by verified contact credits rather than by seat:

     
• Base Plan: $197 per month. Includes 2,000 double-verified contacts at 10 cents each, with sending, warmup, AI personalization, campaigns, and inbox access unlimited.
     
• Higher Credit Tiers: 5,000, 10,000, and 15,000 contacts per month. Volume discounts of 20, 30, and 40 percent apply against the base per-contact rate.
     
• Annual Billing: 25 percent discount. Applied to the monthly price when paid yearly.
     
• Email Accounts: $3.50 per account. Google Workspace inboxes bought inside the app, billed separately from credits.
   

Credits are consumed only when a contact email is double-verified, so unverified lookups are not charged. A free tier is available to explore the platform before paying for verified leads, and every customer is assigned an account manager for technical issues and a cold email specialist for campaign performance.

Pros

     
• Stable Sending: Reviewers report fewer disconnected inboxes and more consistent sending than on platforms they used previously.
     
• Responsive Support: Customers repeatedly credit the support team with quick troubleshooting and hands-on help improving campaigns.
     
• Quick to Learn: Users describe the interface as straightforward, with several launching a first campaign soon after signing up.
     
• Replaces Multiple Tools: Reviewers say it consolidated their lead, sending, warmup, and inbox tools, in some cases reducing monthly outreach costs.
     
• Guided Onboarding: Customers new to cold email note that an assigned specialist walked them through their first setup.
     
• Pay Only for Verified Contacts: Credits are charged only when an email passes double verification, so failed lookups do not consume budget.
   

Cons

     
• Reliability Complaints: Some reviewers describe recurring technical failures and downtime, which the company attributes in part to a wider suspension of Google email accounts affecting outreach platforms generally.
     
• Slow Refunds: A negative review describes a refund process that took several weeks to resolve.
     
• Lean Feature Set: One reviewer notes the platform covers the essentials rather than offering deep advanced functionality.
     
• Results Take Time: Reviewers caution that performance improves only after several campaigns, so buyers expecting immediate returns may be disappointed.
