Seamless.AI Review (2026): Pricing, Features, Pros and Cons

In short Free plan with 50 credits that do not replenish, no card. Seamless.AI publishes no paid prices; sales quotes every paid plan.

In short Of the 10 B2B data provider features we compare, Seamless.AI has 8 in full and 1 more as a paid add-on.

• Says it has 1.8B+ verified business emails and 414M+ phone numbers.
• One credit reveals a contact's emails, cell phones and direct dials together, with no separate phone price.
• Credits for invalid emails come back automatically, without a refund request.
• API access is included on every plan, Free too, and draws from the plan's existing credits.
• Native Salesforce, HubSpot and Microsoft Dynamics integrations, plus a Chrome extension.

• No public prices: the pricing page redirects to a demo form, so every quote goes through sales.
• The Free plan's 50 credits do not replenish.
• Subscriptions auto-renew, and cancelling needs a request at least 60 days before renewal plus a meeting with Customer Success.
• Basic licenses include 250 credits a month, so high-volume research needs Pro or bulk credits.

In short Seamless.AI is a real-time search engine for B2B emails, cell phones and direct dials with built-in emailing, sold to sales teams through custom quotes.

• You want emails, cell phones and direct dials revealed with one credit per contact.
• You plan to pull contacts into your own agents or workflows through the API on any plan.
• You prefer a sales-built package with a credit pool shared across the team.

In short Ken's view: worth it for sales teams that call as much as they email and want phone numbers without a separate credit price, less so for buyers who want to see a public price before talking to sales, or to cancel without a 60-day notice window.

• Seamless.AI does not publish prices: its pricing page redirects to a demo request form. Contact sales for a quote.
• Researching or enriching a contact uses 1 Universal Credit and returns its emails and phone numbers together. AI Assistant interactions and AI-written messages use 0.2 credits each.
• Credits for invalid emails are refunded automatically.
• API access is included on every plan, Free too, and draws from the plan's credits.
• Subscriptions renew automatically. To cancel or stop the renewal, an admin must file a request at least 60 days before the renewal date and meet with Customer Success.

In short Ken is first because it is our product and its Ken Search module competes with Seamless.AI; Apollo.io, RocketReach and UpLead follow.
