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.

Why this matters
Google puts this question in People Also Ask for the "marketing automation" query, which means buyers are asking it while they shop. The answer above is The Wall's editorial position. We index 3,460 verified US growth-services vendors across 10 pillars, and this particular question sits outside what that data can settle.
If you are evaluating vendors in this category, the Automation pillar page carries the full US firm list with rate, team size and headquarters filters.
