Short clips of real prompts with the Seamless and Claude plugin. Start with the walkthrough then checkout our full playlist at your own pace.
The Seamless app connects Claude directly to our real-time contact and company data, as well as our prospecting automation products.
Claude can search for accounts, build lists, verify emails, surface direct dials, research companies, enrich your CRM, and write the outreach — all inside one thread, without you ever leaving the chat.
Build a list in one tool. Export a CSV. Clean it. Re-verify it. Paste names into a research tab. Research each person. Write custom emails 40 times. Upload it all somewhere else.
Describe what you want. Claude finds the accounts, pulls verified contact data, researches each one, and hand writes a personalized campaign ready to send to each person 1-on-1.
A list-build, research, and campaign cycle that took an afternoon now takes one prompt.
Emails and direct dials are validated in real time — not pulled from a stale database dump.
Claude reads the research it just pulled and writes to it: 50 emails, 50 different messages.
No filters, no boolean, no saved-search syntax. If you can describe your ICP, you can run it.
Data, research, and writing in the same thread. Combine it with your CRM, calendar, and email.
No new seat, no new contract. Connect it with the Seamless credentials you already have.
Watch Claude find the accounts, verify the contacts, and write the campaign — without a single export.
Describe the buyer and it returns real matches by title, company, and city.
Work emails and direct dials, each with a confidence score you can see.
Personalized per person from the research it just pulled, in your voice.
Multi-step sequences from your own sending address, paused until you approve.
Opens, replies, and bounces come back into the same conversation.
Re-verify contacts and catch job changes without leaving the chat.
Copy and paste any of these into Claude with the Seamless app switched on. Swap the titles, industries, and geographies for your own ICP.
Twenty verified contacts in one ask — no filters, no list builder, no export.
Every stakeholder who touches the deal, with tenure so you know who is new and who is entrenched.
Size the market, count it by title, and carve the territories in one sitting.
Using Seamless, find US companies in Computer Software with 501+ employees. Give me the total company count. Then for these five titles — VP of Sales, Director of Sales, Sales Manager, Account Executive, CRO — run a separate contact search for each and report the count. Then split the total across 6 balanced territories by region.
One person, one ask. The email, three talking points, and the pain point to lead with.
Email, LinkedIn, and a cold call script — all built off the same researched list.
Find 25 CEOs at SaaS companies in Florida. Research their verified emails, direct phone numbers, and LinkedIn profiles, then build a 3-touch campaign with an email, LinkedIn message, and 30-second cold call script. Personalize the outreach around reducing manual prospecting and generating more pipeline, with a CTA to book 15 minutes this week.
Your champions took new jobs. That is a warm intro at a brand new logo.
Find contacts who previously worked at Anthropic and changed jobs in the last 90 days. Enrich their new work email, then draft a personalized ‘congrats on the new role’ email reintroducing our company and how Seamless can best support them — friendly tone, no hard pitch, under 120 words. Save all as drafts in Seamless. Do not send.
Reverse-engineer what your best customers share, then go find more of them.
Using Seamless, look up Salesforce, HubSpot, Zendesk, and Intercom and summarize what they have in common. Then find 10 similar US companies: Computer Software, 1,001–10,000 employees. At each, find the VP or Head of Customer Success — filter to the Support department and VP or C-Level seniority. Return title, LinkedIn, company size, industry, and revenue. Then enrich those 10 contacts for verified email and phone.
Thirty minutes to the call and nothing in the record? Get the committee and the questions.
