Monitor inbox placement and bounce rates to understand exactly how your emails are performing and make data-driven decisions to improve your sender reputation and engagement over time.

Intelligent Suppression & Deliverability Engine

Protect your sender reputation automatically with AutoSend's advanced global suppression system. This proprietary engine validates every contact and proactively suppresses emails sent to risky addresses, including unsubscribes, previous hard bounces, and spam complaints.

ProspectBuddy

One-Click Save to Airtable or Trello

Eliminate tedious switching between tabs and messy copy-paste forever. With ProspectBuddy installed, you can save any LinkedIn profile directly to your connected Airtable base or Trello board with a single click. The extension seamlessly integrates into your LinkedIn experience, capturing leads instantly and keeping your prospecting workflow incredibly fast and focused. No more manual entry errors or lost leads.

Smart, Selective Data Capture

Not every field on a LinkedIn profile is relevant to your process. ProspectBuddy gives you complete control by letting you select only the specific data points you need—like name, current role, skills, about section, or job experience—before sending. This ensures your Airtable or Trello records are clean, structured, and contain only the most valuable information for your outreach or recruitment pipeline.

Verified Contact Enrichment

Go beyond the public profile. ProspectBuddy helps you find verified business emails and direct phone numbers (for B2B users) associated with the LinkedIn profile. This powerful enrichment feature, powered by secure credits, puts accurate contact information directly into your workflow, dramatically increasing your reachability and saving you hours of manual searching across different platforms.

AI-Personalized Outreach Generation

Turn profile data into compelling conversations in seconds. Using the rich data from the LinkedIn profile, ProspectBuddy's AI can generate tailored outreach messages for you. This feature helps you craft personalized connection requests or follow-up emails that resonate, boosting your response rates without sacrificing the personal touch that manual prospecting requires.

ProspectBuddy

Sales Teams & SDRs Building Pipelines

Sales development representatives and account executives can rapidly build targeted prospect lists.

Recruiters & Talent Acquisition Specialists

Recruiters managing high-volume candidate sourcing can save precious time. ProspectBuddy allows them to capture promising candidate profiles from LinkedIn and instantly add them as structured cards to a Trello hiring pipeline or an Airtable talent database. This ensures all candidate information is organized, accessible, and ready for the next stage without administrative drag.

Founders & Startup Operators Networking

Founders and operators building their network or seeking partnerships can do so efficiently. Instead of losing track of interesting contacts, they can one-click save profiles to a dedicated Airtable or Trello board. They can then capture key details and use the AI to help draft a relevant, personalized outreach message, making every new connection intentional and impactful.

Agencies Managing Client Prospecting

Marketing, PR, or lead gen agencies managing prospecting for multiple clients can maintain clean, separate workflows. By using different Airtable bases or Trello boards for each client, teams can use ProspectBuddy to manually gather and enrich leads from LinkedIn, ensuring all captured data is perfectly formatted and ready for client reporting or handoff.

ProspectBuddy FAQ

Is ProspectBuddy safe to use with LinkedIn?

Absolutely. ProspectBuddy is built explicitly for safe, manual LinkedIn prospecting. It does not perform any automated actions, scraping, or bot-like behavior on your behalf. You remain in full control, working directly from the LinkedIn profile page. This manual approach makes it a fully compliant and safer alternative to bulk scraping tools and risky automation workflows that can jeopardize your account.

How do I connect my Airtable base?

Connecting is quick and easy. Simply click “Airtable” on the Connect screen within the ProspectBuddy extension. You'll then select the specific bases or workspaces you want to grant access to and click “Grant access.” Once connected, the status will be visible on your Profile page. You can disconnect this access at any time with just a few clicks.

How do credits work in ProspectBuddy?

Credits are your internal balance used for specific premium actions within the extension, such as searching for a verified business email. You purchase credits securely via Stripe, and your balance updates automatically after successful payment. For example, an email search costs 10 credits, and importantly, credits are only consumed if a valid email is successfully found.

Why are some of my Airtable fields not showing up?

ProspectBuddy supports specific, compatible Airtable field types to ensure data integrity. Supported types include: Attachment (for photos), URL, Text (for name, skills, about, etc.), Email, and Phone. If you have a field in your table with an unsupported type (like a checkbox, formula, or rollup), it will not appear in the dropdown menu for field mapping during setup.
