Seamless.AI
Pros
- + One credit returns both email and a phone number — the flat credit model beats the 5:1 and 10:1 phone ratios of Lusha and LeadIQ in my comparison
- + Free plan with 50 credits and no credit card is the easiest trial entry in the B2B data category (seamless.ai pricing page, captured September 2026)
- + Chrome extension pulls contacts while browsing LinkedIn Sales Navigator and company pages
- + Universal Credits pool across a team since June 2026, with admin-set per-user limits
- + G2 rating of 4.4 across 5,277+ reviews shows a large, genuinely satisfied user base for US outbound
Cons
- - Reported 20-30% of records inaccurate or outdated on G2; credits are spent even when the research returns a bounce
- - No published price for any paid plan — Pro and Enterprise route to sales and every third-party price is an estimate
- - Trustpilot sits at roughly 1.4/5 on billing disputes and auto-renewal friction; terms renew 12 months unless changed 60 days before renewal
- - GDPR concerns for EU/UK prospecting and a March 2025 LinkedIn restriction on its tooling
- - Buyer Intent, AI Assistant, Autopilot and Data Enrichment are paid add-ons on top of the subscription
Amplemarket
Pros
- + Consolidation that holds up: data, signals, sequences, dialing and deliverability in one platform replaced three-to-five tools for teams I compared
- + Job-change and intent triggers arrive pre-wired to a recommended sequence with mailbox rotation — the workflow I found myself acting on fastest
- + Deliverability layer is real: the Domain Health Center flagged SPF/DKIM issues in my first session and warm-up runs in the background
- + G2 record of about 4.6/5 across roughly 700 reviews, with implementation around a month and reported ROI at eight months
- + Natural-language prospect search beats boolean filter building for daily use
Cons
- - Startup plan at $600/month for two users (amplemarket.com/pricing) is expensive for teams under five sellers
- - Growth and Elite pricing is quote-only; the headline MCP and AI Agents capabilities are add-ons
- - The 96.5% phone accuracy and sub-3% bounce figures are vendor-run benchmarks; a customer testimonial reports about 60% phone coverage on target leads
- - G2's complaint tags — missing features, learning curve, sequence and integration issues — cluster at the edges of the platform
- - 140,000-contact cap on Startup and roughly a month of setup make the first quarter a project, not a plug-in
