Consider switching to ZoomInfo: Similar functionality in lead generation and data verification.
Seamless.AI is a real-time search engine that crawls and verifies contact data at the moment of lookup, while ZoomInfo maintains a static database that is periodically refreshed. Seamless.AI claims 1.8B+ verified business emails and 414M+ mobile numbers with real-time verification. ZoomInfo generally offers deeper firmographic data, more detailed org charts for mapping buying committees in large enterprises, and manually verified records — but at a significantly higher price point. Seamless.AI does not publish its paid plan pricing (Pro and Enterprise require contacting sales), though it is widely regarded as more affordable than ZoomInfo for teams that prioritize volume over firmographic depth.
Seamless.AI claims 98% data accuracy on its marketing materials. Real-world user reviews on G2 and Capterra report that email accuracy is generally strong but can produce 20–30% bounce rates in cold campaigns, and phone number accuracy — particularly for mobile numbers and non-executive roles — is lower. Data coverage is strongest for North American professionals and tends to be less comprehensive for mid-market companies, smaller firms, and international contacts. Users consistently recommend running email verification tools on exported lists before launching campaigns, regardless of the provider.
One Seamless.AI credit equals one contact lookup that returns both a phone number and an email address. The Free plan provides 1,000 credits per user per year, granted monthly. Pro plans offer a daily credit refresh with volume determined during the sales process. Credits are consumed per search attempt — meaning a credit is used even if Seamless.AI cannot find complete data for a contact, which is a recurring user complaint. Credits do not roll over between periods on the Free plan. Enterprise plans offer custom credit packages negotiated with sales.
Yes. Seamless.AI does not publish dollar amounts for its Pro or Enterprise plans on its pricing page. Both require contacting sales for custom quotes. The Free plan ($0, 1,000 credits/user/year) is the only self-serve tier. The vendor's FAQ mentions that annual subscriptions receive a discount, but no specific dollar amounts are disclosed publicly. Seamless.AI also offers a Switch and Save Program with up to 50% off for prospects switching from a competing provider. This pricing opacity is reflected in the platform's CTI transparency score.
Seamless.AI integrates with 6,000+ tools via one-click connections. Native CRM integrations include Salesforce, HubSpot, Salesloft, Zoho, Pipedrive, Microsoft Dynamics, and Outreach. The platform also offers an API (available as an add-on on Pro and Enterprise plans) for embedding contact data directly into custom workflows. The Chrome Extension works alongside LinkedIn and company websites for real-time prospecting. Enterprise plans support SSO via Okta, Google, and other providers for centralized authentication.
Seamless.AI holds SOC 2 Type II certification across all plan tiers — including the Free plan. The platform is also ISO 27001 certified, GDPR compliant, and CCPA compliant. Enterprise security features include SSO options (Okta, Google, and more), military-grade encryption, Enterprise DDoS and bot protection, multi-region redundancy, and automated weekly security updates. These compliance standards are available to all users, not gated behind Enterprise-only access.
Seamless.AI has expanded beyond data into a full revenue platform. The Engagement Hub product called Connect — now included on all plans — provides built-in emailing with sending and automation, an AI-powered calling dialer, social selling tools, and task management. This means users can prospect, find contacts, and execute multichannel outreach without leaving the platform. Additionally, AI Agents automate multi-step workflows like outbound campaign creation, inbound lead response, CRM data hygiene, and customer success monitoring.
The Free plan supports 1 user with 1,000 credits per year (granted monthly), includes the real-time search engine, Connect (emailing, calling, tasks), Pitch Intelligence, Job Changes filter, and premium integrations — but excludes Admin Seat, Advanced Org Management, and all add-ons (Buyer Intent, Data Enrichment, Autopilot, API, AI Assistant). Pro adds per-user pricing with a daily credit refresh, unlimited exports, Free Admin Seat, Advanced Org Management, priority support queue, live chat, and eligibility for all add-ons. Enterprise unlocks unlimited users, custom credit packages, a Dedicated Success Manager, Quarterly Business Reviews, and phone support.
