Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@ContactOut check if this LinkedIn profile has contact info available before I use credits: linkedin.com/in/jane-doe-product
ContactOut reports that this profile has a personal email and work email available, but no phone number on file. Because you used the availability-check endpoint, no credits were consumed. If you proceed to enrich the full profile, you will spend 1 search credit plus 1 email credit for each email type you request.
The Check LinkedIn Contact Availability tool lets you preview what data exists before committing credits. This is especially useful when prospecting at scale — you can filter candidates by data availability, then enrich only the profiles that meet your outreach requirements.
@ContactOut add these 15 LinkedIn URLs to my 'Q1 Outbound' campaign so they receive the sequence starting tomorrow.
ContactOut added 15 recipients to campaign 'Q1 Outbound' (ID: cmp_abc123). All profiles will enter the sequence at step 1 when the campaign resumes. Note that 2 profiles were already in the campaign and were skipped to avoid duplicate outreach. The campaign is currently active, so new recipients will begin receiving emails within 24 hours.
Add Campaign Recipients is a write operation that immediately modifies your live campaign. If the campaign is running, new recipients start receiving emails as soon as they're added. Always verify the campaign state and recipient list before bulk-adding contacts to avoid unintended outreach or duplicate sends.
@ContactOut estimate how many software engineers in San Francisco with 5+ years experience have verified work emails, then draft a short pitch for the top 10.
ContactOut's Count People endpoint estimates 3,200 matching profiles, with approximately 2,400 work emails available. The search has not yet consumed credits. Based on typical SaaS hiring needs, a concise pitch might open with: 'We're building tools that help senior engineers ship faster — would love to show you our new CI/CD integration.' Once you confirm the search parameters, I can enrich the top 10 profiles and personalize outreach using their current role and company context.
Count People provides a credit-free preview of search volume and data availability, letting you refine filters before committing to enrichment. Pairing this with AI-drafted messaging helps you move from audience sizing to personalized outreach in one workflow, but remember that actual enrichment will consume search and email credits per profile.
Use-case deep-dives
When ContactOut wins for high-volume prospecting campaigns
A 6-person sales team at a B2B SaaS company runs weekly campaigns targeting 200-300 prospects from LinkedIn Sales Navigator lists. ContactOut's batch job tools (Create LinkedIn Contact Info Batch Job, Add Campaign Recipients) let the team queue 1,000 profiles overnight and push verified emails straight into sequences without manual copy-paste. The credit model is transparent: you pay per enriched profile, so budgeting is predictable when you know your monthly target list size. The threshold: if your team closes fewer than 10 deals a quarter, the credit cost per closed deal gets steep compared to manual research. If you're running consistent outbound at 500+ contacts a month, ContactOut pays for itself in saved research hours and keeps your CRM current.
ContactOut for technical recruiting at 20-50 hires per year
A 3-person recruiting team at a 40-employee startup needs to fill 8 engineering roles over the next quarter. They source passive candidates from GitHub and LinkedIn, then use Enrich LinkedIn Profile and Check LinkedIn Contact Availability to verify reachable emails before cold outreach. The availability check is the key: it shows whether a profile has contact data without burning credits, so the team can prioritize high-signal candidates before enriching. The trade-off: ContactOut requires a paid production entitlement for these checks, so it's overkill if you're hiring fewer than 15 people a year. At 20+ hires annually, the time saved on manual email hunting and the higher reply rates from verified personal emails justify the subscription and per-contact cost.
When ContactOut is overkill for low-frequency relationship building
A 2-person partnerships team at a fintech company reaches out to 10-15 potential integration partners each quarter. They need decision-maker contact info, but the volume is low and the relationships are warm (often starting from a mutual connection or conference intro). ContactOut's Enrich Person and Enrich Companies by Domain tools work, but the API-key auth and credit-per-lookup model are built for scale, not sporadic research. The team would burn credits slowly and pay for capacity they don't use. The honest call: if you're doing fewer than 50 cold contacts a quarter, manual LinkedIn sleuthing or a one-time Hunter.io search is cheaper and just as fast. ContactOut makes sense when you need repeatable, automated enrichment that feeds a CRM or outreach tool daily.
Frequently asked
What does the ContactOut MCP let me do in Switchy?
It lets your team enrich LinkedIn profiles with personal emails and phone numbers, verify email deliverability, and add recipients to outreach campaigns — all from a Switchy chat. You can search for people by employer or job title, check contact availability before spending credits, and queue bulk jobs for up to 1,000 profiles at once. It's built for sales and recruiting teams who need contact data without leaving the workspace.
Do I need a paid ContactOut account to use this MCP?
Yes. The MCP requires an API key from a paid ContactOut production plan. Free-tier keys won't work for most tools — checking LinkedIn availability, counting search results, and enriching profiles all require an active subscription. You'll also consume ContactOut credits when you reveal emails or phone numbers, so make sure your plan has enough credits for your team's volume.
Can the MCP send cold emails or just add people to campaigns?
It can only add recipients to existing ContactOut campaigns; it doesn't compose or send emails directly. If you want to launch outreach, you'll create the campaign in ContactOut's web app first, then use the MCP to populate it with enriched contacts. For one-off emails or custom sequences outside ContactOut, you'll need a separate email tool or MCP.
How is this different from scraping LinkedIn myself or using the ContactOut Chrome extension?
The MCP automates bulk workflows that the Chrome extension can't handle — like enriching 1,000 profiles in one batch job or verifying 100 emails asynchronously. It also logs every action in Switchy's audit trail, so your team knows who revealed which contact and when. If you only need a handful of emails per week, the extension is faster; for systematic prospecting, the MCP saves hours.
Who on my team should connect the ContactOut API key?
Whoever owns your ContactOut subscription and is comfortable with the team consuming credits through Switchy. Once connected, any Switchy member can trigger enrichment or campaign actions, so you'll want to set workspace rules about credit budgets and approved use cases. If your sales ops or recruiting ops person manages ContactOut already, they're the natural owner.
