Apollo.io vs lemlist: pricing, features and which to choose

Apollo.io is a sales intelligence and go-to-market platform made by ZenLeads, Inc., doing business as Apollo.io. Founded in 2015, it released its first product in 2016 and says it reached $150 million in annual recurring revenue in May 2025. Apollo also reports more than 500,000 companies using the platform and more than 50,000 weekly active users in 2025. Its 2023 Series D raised $100 million at a reported $1.6 billion valuation. The product combines a business contact database with prospect search, enrichment, sequencing, calling, pipeline support, analytics, and AI features. That combination places Apollo closer to a sales operating system than a standalone lead database, serving founders, sales teams, marketers, and revenue operations groups.

Apollo’s workflow usually begins with finding people or companies through filters, then selecting records for enrichment, lists, sequences, or exports. Email campaigns are available on every account. Free users can connect Gmail, while paid users can connect Microsoft Office and other providers. Teams can create sequences, manage pipeline activity, record calls, prepare for conversations, and review AI-generated insights. The AI Assistant accepts natural-language requests, uses Apollo data and saved messaging context, and can find decision-makers, research accounts, build sequences, export lists, and report on performance. Scheduled agents can run some outbound tasks in the background. Permissions still govern available actions, and Apollo advises reviewing generated messages, matches, and credit estimates before execution.

Apollo’s main limitation is pricing and usage complexity: the final amount depends on seats, billing frequency, credits, add-ons, and selected features. Basic includes one mailbox, 250 daily emails, five team workflows, and 1,000 records per selection, while Professional raises several limits and adds AI and call features. Standard plans are for internal business use, so powering external products, sharing data with customers, or reselling it requires a separate agreement. Apollo competes with ZoomInfo, Cognism, Outreach, Salesloft, and HubSpot Sales Hub. It combines data and enrichment more closely than Outreach or Salesloft, and adds execution tools beyond ZoomInfo or Cognism. Choose Apollo if one team needs prospect intelligence, outbound execution, enrichment, and AI actions together.

lemlist is a Paris-based B2B sales engagement company founded in 2018. It supports email, LinkedIn, SMS, WhatsApp, calling, lead discovery, enrichment, intent signals, AI personalization, deliverability, CRM connections, and a unified inbox. The company says it is bootstrapped and profitable and serves more than 20,000 customers. Tech.eu reported that its founders declined a $30 million venture offer and reached $5 million in annual recurring revenue without external funding. Other reports describe a 2021 $30 million secondary transaction in which Expedition Growth Capital acquired a 20 percent stake. In October 2025, lemlist announced a self-financed acquisition of Claap, a call recording, transcription, and sales intelligence company. The funding history is therefore better described as initially bootstrapped with a later reported growth-equity transaction.

A typical lemlist workflow starts with Lead Finder, CRM import, or an existing contact list. Users can enrich records, divide them into segments, and build sequences combining email with LinkedIn automation, SMS, WhatsApp, or calling. Replies are handled in a multichannel inbox, while CRM integrations connect campaign activity with HubSpot or Salesforce. AI Variables and lemAgent can generate personalized fields and signal-based actions. lemwarm prepares mailboxes and supports deliverability work. The company describes Lead Finder as drawing from more than 450 million B2B records, although records can be incomplete or outdated and must be checked before outreach. VoIP calling is included in Multichannel Expert, which documents 400 minutes per user each month. WhatsApp is available as a separate paid add-on.

lemlist covers more native channels than Smartlead, Instantly, or QuickMail, but the pricing structure is harder to forecast. Email is priced by monthly volume, Multichannel Expert by user, and enrichment, intent signals, and WhatsApp can add separate charges. The hosted service has no documented open-source core or customer-managed deployment. Its privacy materials describe service improvement and subprocessors without a blanket promise that customer content is never used to train general models. Customers remain responsible for list quality, consent, and outreach compliance. Smartlead is stronger for mailbox rotation and sending infrastructure, Instantly for high-volume cold email, and Apollo for data combined with engagement. lemlist is the better choice for B2B teams and agencies that want email, LinkedIn, SMS, WhatsApp, calling, enrichment, and CRM activity in one workspace.
