What is meant by marketing automation?
Marketing automation is software that executes marketing workflows on rules and triggers instead of manual sends — welcome emails, drip campaigns, lead scoring, behavioral segmentation, personalization, cross-channel orchestration. HubSpot, Marketo, ActiveCampaign, and Klaviyo are the market leaders. It's what lets a 5-person marketing team run programs that would otherwise require 20 people.
