What is Overloop?
Overloop is a sales engagement platform that automates multi-channel outbound campaigns for B2B sales teams and founders. It sources prospects, writes personalized emails, and runs LinkedIn outreach without manual input. The platform draws from a database of over 450 million verified B2B contacts to build targeted lead lists. Users define their ideal customer profile and Overloop populates and works those lists automatically. Campaign sequences are built from a decade of real outbound data covering timing, messaging, and follow-up steps. Overloop also offers free tools including an ROI calculator, email spam checker, domain health checker, and email infrastructure calculator.

Real-World Applications
A founder running outbound without a sales team can use Overloop to source contacts, write emails, and run sequences across email and LinkedIn without hiring an SDR. The sales engagement platform handles lead generation and follow-up work so the founder stays focused on calls and closing.
A B2B sales team at a SaaS company can set an ideal customer profile, let Overloop pull matching contacts from the database, and launch personalized multi-channel campaigns within minutes. The sales engagement platform tracks replies, clicks, and bounces across every sequence and feeds that data back into campaign refinement.
A recruiting firm or staffing agency prospecting for new clients can filter the contact database by company size, location, and industry to reach decision-makers directly. Automated LinkedIn outreach runs alongside email to build visibility and grow the agency’s network at scale.
A marketing or growth agency managing outbound for multiple clients can run separate campaigns per account with messaging tailored to each client’s voice and brand. Overloop’s personalization layer pulls context from each prospect’s website and social profiles so every email reads as individually written rather than templated.
