Pros & Cons
Apollo
Pros
- Prospect database, email sequencing, dialer and enrichment come in one subscription, so teams buy fewer tools.
- The free plan has no time limit and lets a team try the full prospecting workflow.
- Reviewers rate ease of use highly, and G2 shows about 4.7 out of 5 from roughly 9,700 reviews.
- Admins can pool credits across the team and set per-user caps.
Cons
- Many reviews report inaccurate data, especially mobile numbers and contacts outside North America.
- Credits expire each cycle, phone reveals cost about eight times as much as an email, and credits are spent even on bad records.
- Support is the lowest-rated G2 subcategory, and Trustpilot shows a TrustScore of about 3.1.
- API access and SSO require the top Custom plan, and every seat must be on the same plan.
Kustomer
Pros
- The CRM timeline shows orders and history for each customer in one view, which gives both AI agents and reps full context.
- Channel coverage is broad and includes voice, WhatsApp and TikTok Shop alongside email and chat.
- The developer platform is extensive, with 10 REST APIs, webhooks, mobile chat SDKs and an MCP server.
- Its compliance coverage is strong: SOC 2, ISO 27001, ISO 27701, ISO/IEC 42001 and GDPR.
- G2 reviewers rate it 4.5 out of 5 across more than 500 reviews.
Cons
- No prices are published, so every buyer must go through a sales quote.
- G2 reviewers report pricing model changes announced with short notice.
- Reviews describe a steep learning curve and setup that often needs dedicated admin staff.
- Some end users on Trustpilot criticise the customer-facing AI for rigid flows and difficulty reaching a human.
- AI features are billed on top of the platform, which raises total cost.
