B2B Sales Glossary
Clear, practical definitions for the terms that matter in modern B2B sales outreach, cold email, and AI-powered prospecting.
Cold Email
A cold email is an unsolicited email sent to a recipient who has no prior relationship with the sender. In B2B sales, cold email is one of the most effective outbound prospecting channels — used to introduce a product, request a meeting, or start a sales conversation with a potential buyer.
Read definitionSales Engagement Platform
A sales engagement platform (SEP) is software that helps sales teams automate and manage their outreach across multiple communication channels — typically email, phone, LinkedIn, and SMS. SEPs centralize prospect interactions, automate follow-up sequences, and provide analytics to optimize conversion rates.
Read definitionAI SDR
An AI SDR (AI Sales Development Representative) is an artificial intelligence system that performs the core functions of a human SDR: identifying prospects, sending personalized outreach, handling replies, following up, and booking meetings. AI SDRs can operate 24/7 across multiple channels including email, LinkedIn, SMS, and phone.
Read definitionMulti-Channel Outreach
Multi-channel outreach is a sales prospecting strategy where reps engage potential customers across multiple communication channels — typically email, LinkedIn, phone calls, and SMS — in a coordinated, automated sequence. The goal is to increase touchpoints and response rates beyond what any single channel can achieve.
Read definitionEmail Deliverability
Email deliverability refers to the ability of an email to successfully reach the recipient's primary inbox rather than being filtered to spam, promotions, or blocked entirely. In B2B cold email, deliverability is the single most important technical factor — because even the best-written email is worthless if it never reaches the prospect.
Read definitionSales Automation
Sales automation is the use of software, AI, and technology to automate repetitive tasks in the sales process — including prospect research, email outreach, follow-ups, data entry, meeting scheduling, and CRM updates. The goal is to let sales reps focus on high-value activities like building relationships and closing deals.
