Why
Why Are People Switching From Seamless.AI to Outbound System
Seamless.AI sells credits on quote-based plans. Teams choose Unlimited B2B Data for flat, published pricing and unlimited exports.
Published Pricing
Seamless.AI's pricing page is a form that asks for your monthly contact volume and company size before you see a number. Our plans are published: $199, $499, or $999 a month for Unlimited B2B Data. You can compare all three on the site, and the only differences are search speed and the number of team seats included.
No Credits at All
Credits are the unit Seamless.AI sells, and it refunds a credit when an email turns out to be invalid. Unlimited B2B Data has no credits at all, so there is nothing to refund, ration, or track. Every search and export is unlimited on every plan, and your team never has to budget leads against a balance.
Mobile Numbers Included
Mobile numbers come with every Unlimited B2B Data plan. The database includes 53M+ mobile numbers and direct dials, and they export alongside emails with no extra credits or phone add-on. Your callers get complete records in the same file, and building a larger calling list never changes what you pay Outbound System.
Build Full Lists
Search 390M+ contacts with 100+ filters and buying signals, using boolean logic or plain English, then export as many as you need in one pass. Starter builds a 50,000-lead list in about 5 minutes, and Scale does it in about 12 seconds. Each contact carries up to 165 data fields, so your list arrives enriched and ready to use.
Works With Your AI Assistant
Your AI assistant can build lists directly. API, dashboard, and MCP access are included on every plan, so Claude, ChatGPT, Cursor, or your own agents can ask for a list in plain English and get contacts back from 390M+ records. There is no extra license for API access and no credit charged per contact on Unlimited B2B Data.
Month-to-Month, Cancel Anytime
Contract terms on Seamless.AI are not published, so you learn them in the quote. Unlimited B2B Data runs month to month with no minimum term, and you can cancel from your dashboard in seconds. Before you pay, pull 5,000 fully enriched leads free with no card required and see what Outbound System covers in your market.
What to Ask in a Seamless.AI Quote
Seamless.AI prices by quote and credits, so ask three things first. How many credits do you get a month, and do unused ones expire? Is it billed per seat, and on what term? Are job changes, buyer intent, and enrichment extra? Unlimited B2B Data answers all three up front, with unlimited exports and 3 to 25 seats from $199 a month.
Want Us to Run the Outreach Too?
With Seamless.AI, your reps still prospect and run outreach themselves. Our done-for-you service takes that work off your team. Our people build the list, set up inboxes and domains, write the copy, manage deliverability, and run cold email, AI cold calling, and LinkedIn for you, from $1,499 a month, with a dedicated account manager.
