Which one to pick

Pick Seamless.ai if you want to try the data before talking to anyone: 50 free credits, then a quote sized by how many contacts you need a month. Its credit back on invalid emails lowers the cost of bad data.

Pick ZoomInfo if the buyer is a revenue team, not one rep: separate sales and marketing packages, credits that cover exports and integration calls, and a free trial on the sales packages.

Both claim large databases. Claims are not measurements, so run the same 100 contacts through both trials and count what connects.

Where looot fits

An agent with one looot key covers the lookups both sell: people search by title, work emails, mobile numbers, company enrichment and email verification, paid per call with no seat. The live price of each is listed below.

Neither vendor's own API is in the catalog today, so the agent uses other providers for these jobs. ZoomInfo's intent signals and org charts have no match in the catalog.

Prompts

Ask your agent to take over the jobs

One prompt for each tool's jobs. Paste it into the agent you already use, after setting up looot.

Seamless.ai jobs
Use looot to find people with a given job title at the companies I list, then find their work emails and phone numbers. If you have not yet, set up https://looot.ai/skill.md first. Then search the looot catalog for each step, check the price of each endpoint before you call it, run the cheapest one that fits, and show me the results as a table.

ZoomInfo jobs
Use looot to find the decision makers at the companies I give you and return their titles, work emails and phone numbers. If you have not yet, set up https://looot.ai/skill.md first. Then search the looot catalog for each step, check the price of each endpoint before you call it, run the cheapest one that fits, and show me the results as a table.

Questions about Seamless.ai vs ZoomInfo

Seamless.ai, if you want to start free and pay by contacts with refunds on invalid emails. ZoomInfo, if several teams need contacts, intent and org data under one contract. Test both on the same list of your own target accounts before you sign.

Neither publishes a price, checked 2026-11-03. Seamless.ai sends you to a form that asks how many contacts you need a month. ZoomInfo prices by features, number of licenses and credit usage through its sales team.

Seamless.ai says it is not: it describes itself as a real-time search engine that finds and verifies contact data when you search. ZoomInfo sells access to its data by licenses and credits, with one credit per export.

Seamless.ai is free for up to 50 credits. ZoomInfo has no free plan; it offers a free trial on Professional, Copilot Advanced and Copilot Enterprise and a demo on its marketing packages.

Seamless.ai lists an API, MCP servers and bulk credits among its products. ZoomInfo lists no separate API plan on its pricing page, and its credits are used when its integrations make an API call. Ask either one which package includes API access.

Seamless.ai says it refunds the credit automatically when an email is invalid. ZoomInfo's pricing page does not describe a refund. Whatever you use, verify emails before a send, because a bounce hurts your domain more than the lost credit.

For the lookups, mostly. With one looot key an agent searches people by title, finds work emails and mobile numbers, enriches companies and verifies every email, paid per call. Intent signals and org charts are not in the catalog.
