The language of outbound, defined
Plain-English definitions of the terms that run modern B2B outbound, from ICP and buying signals to deliverability, cadences and ABM. Written by the team that builds these systems every day.
Outbound sales
Outbound sales is the practice of proactively reaching prospects who have not contacted you first, through channels like cold email, cold calling and LinkedIn, to start sales conversations. It contrasts with inbound, where prospects come to you through content, search or referrals.
Outbound agency
An outbound agency is a service provider that builds and runs a company's outbound sales motion, including targeting, sending infrastructure, copy and multichannel outreach, to book qualified meetings. A modern outbound agency is measured on meetings booked, not on activity like emails sent.
Cold email
Cold email is an unsolicited but permission-compliant email sent to a prospect who fits your ideal customer profile, with the goal of starting a relevant business conversation. Effective cold email depends as much on deliverability and targeting as on the message itself.
Cold calling
Cold calling is reaching prospects by phone without a prior relationship to qualify interest and book meetings. It still works in B2B when calls are tightly targeted and paired with other channels rather than used as a standalone volume play.
Email deliverability
Email deliverability is the ability of your emails to reach the recipient's inbox rather than the spam folder or being blocked. It is driven by domain reputation, authentication (SPF, DKIM, DMARC), list quality and engagement, and it determines whether any of your outreach is even seen.
Inbox placement
Inbox placement is the share of delivered emails that actually land in the primary inbox rather than spam or a promotions tab. It is a more honest measure of deliverability than a simple delivered rate, because a delivered email in spam is effectively invisible.
Email warmup
Email warmup is the process of gradually increasing sending volume from a new domain or mailbox while generating positive engagement, so mailbox providers learn to trust it. Skipping warmup is one of the fastest ways to land new cold email campaigns in spam.
SPF (Sender Policy Framework)
SPF is an email authentication standard that lets a domain owner publish which servers are allowed to send mail on its behalf. Receiving servers check SPF to help verify that a message is not spoofed, and missing or misconfigured SPF hurts deliverability.
DKIM (DomainKeys Identified Mail)
DKIM is an authentication method that attaches a cryptographic signature to outgoing email, letting receivers confirm the message was not altered and genuinely came from the sending domain. It is one of the three core records (with SPF and DMARC) that protect deliverability.
DMARC
DMARC is a policy layer built on SPF and DKIM that tells receiving servers what to do with mail that fails authentication, and sends reports back to the domain owner. A correct DMARC policy is now effectively required for reliable bulk sending to major providers.
Sending domain
A sending domain is the domain used to send outreach email. Outbound teams typically use dedicated secondary domains, separate from the company's primary domain, so that any deliverability damage from cold campaigns never harms the main business email.
ICP (Ideal Customer Profile)
An ICP is a precise description of the companies that get the most value from your product and are most likely to buy, defined by attributes like industry, size, business model and technology. A sharp ICP is the foundation of outbound, because targeting the wrong accounts wastes every other effort downstream.
Buying signal
A buying signal is an observable event or attribute suggesting an account may be ready to buy, such as new funding, relevant hiring, leadership changes, technology adoption or website intent. Signal-driven outbound reaches prospects when a signal gives them a reason to respond now.
Trigger event
A trigger event is a specific change at a target account that creates a timely reason to reach out, like a funding round, a new executive, a product launch or a merger. Anchoring outreach to a trigger event dramatically increases relevance and reply rates.
Lead generation
Lead generation is the process of identifying and engaging potential customers and capturing their interest so they can enter the sales pipeline. In B2B it spans both inbound (content, search) and outbound (cold email, calling, LinkedIn) sources.
Demand generation
Demand generation is the broader marketing effort to create awareness and interest in a category or product, often before a buyer is ready to talk to sales. It differs from lead generation, which focuses on capturing and qualifying individual prospects.
Appointment setting
Appointment setting is the outbound activity of booking qualified sales meetings directly onto a sales rep's calendar. Quality appointment setting prioritizes fit and intent so reps spend time on real opportunities rather than no-shows and bad-fit calls.
SDR (Sales Development Representative)
An SDR is a salesperson focused on the top of the funnel: prospecting, qualifying inbound and outbound leads, and booking meetings for account executives to close. SDR and BDR roles are often used interchangeably.
BDR (Business Development Representative)
A BDR is a rep focused on generating new pipeline, typically through outbound prospecting into accounts that have not engaged yet. The role overlaps heavily with the SDR role, with the label varying by company.
Sales cadence
A cadence (or sequence) is a planned series of outreach touches across channels and days, for example a mix of emails, LinkedIn actions and calls over a few weeks. Most replies come from follow-up steps, so a structured cadence outperforms one-off sends.
Multichannel outreach
Multichannel outreach coordinates several channels, such as email, LinkedIn and phone, into one sequence aimed at the same prospect. Coordinated touches across channels raise the odds a buyer notices and responds compared with relying on a single channel.
ABM (Account-Based Marketing)
ABM is a strategy that treats specific high-value accounts as markets of one, coordinating sales and marketing (including targeted ads) around a defined list of companies. In outbound, ABM ads warm named accounts so cold outreach lands against a familiar brand.
Data enrichment
Data enrichment is the process of adding accurate, useful attributes to a contact or company record, such as role, company size, technologies, funding or verified email. Enrichment turns a thin list into the targeting and personalization fuel that outbound depends on.
Waterfall enrichment
Waterfall enrichment queries multiple data providers in sequence for each record, taking the first reliable result so coverage and accuracy are higher than any single source. It is a common pattern in modern data tooling like Clay.
Personalization at scale
Personalization at scale is the use of data and automation to make each outbound message specifically relevant to its recipient without writing every one by hand. Done well it references a real reason to reach out; done badly it produces generic openers that read as templates.
Open rate
Open rate is the share of emails recorded as opened. It has become an unreliable metric because privacy features like Apple Mail Privacy Protection inflate opens, so experienced teams optimize for replies and meetings instead.
Bounce rate
Bounce rate is the percentage of emails that could not be delivered, often due to invalid or outdated addresses. High bounce rates flag your domain to mailbox providers and quietly damage deliverability, which is why list verification matters.
Spam trap
A spam trap is an email address used by providers and blocklists to catch senders with poor list hygiene. Hitting traps signals that you are emailing addresses you should not, and can severely harm sender reputation.
MQL vs SQL
An MQL (marketing qualified lead) has shown enough interest to be worth sales follow-up, while an SQL (sales qualified lead) has been vetted by sales as a real opportunity. Outbound aims to produce SQLs and booked meetings, not just top-of-funnel interest.
Lead scoring
Lead scoring assigns a value to leads based on fit and behavior so teams prioritize the prospects most likely to convert. In signal-driven outbound, scoring on real buying signals decides who gets contacted first.
GTM (go-to-market)
Go-to-market is the overall strategy for how a company reaches customers and drives revenue, spanning positioning, channels, pricing and sales motion. Outbound is one engine within a broader GTM system.
Pipeline
Pipeline is the collection of active sales opportunities at each stage from first meeting to close, and its size and quality forecast future revenue. The purpose of outbound is to create qualified pipeline predictably.
CAN-SPAM and opt-out
CAN-SPAM is the US law governing commercial email, requiring honest headers, accurate subject lines, a valid physical address and a working unsubscribe. Compliant outbound always honors opt-out requests promptly and identifies the sender clearly.
CRM (Customer Relationship Management)
A CRM is the system of record for contacts, accounts and deals, such as HubSpot or Salesforce. Wiring outbound activity and replies into the CRM keeps reporting accurate and ensures no booked meeting or interested prospect falls through the cracks.
