Marketing Automation
What Is Marketing Automation?
- Automating repetitive marketing with rules and data
- A 'when they act, send this' scenario
- Personalized communication at scale
Adopting MA shifts a marketer’s job from “what do we send this month?” to “what should go out once which conditions are met?” Planning a single campaign and blasting it to the whole list falls apart once leads pass a few hundred, because there aren’t enough hands. Switch to a structure where a scenario, once designed, keeps running, and every new lead gets follow-up of the same quality. What decides results is no longer how hard the marketer works but how well the workflow is designed.
The boundaries between these tools are often confused. A bulk email tool handles only 'sending to a list,' a CRM handles records after sales has met the lead, and MA takes responsibility for the stretch in between, from the moment a lead shows interest until it is ready for sales to take over. Scoring also has to be split along two axes. Using both attribute scores such as job title, industry, and company size and behavior scores such as pricing page visits and email clicks is what separates 'someone highly interested but without decision-making power' from 'someone quiet who holds the budget.' Using attribute scores alone amounts to grading business cards.
Running it in Korea also means weighing the legal conditions. Under the Network Act (Act on Promotion of Information and Communications Network Utilization), promotional messages require prior consent, and sending between 9 p.m. and 8 a.m. requires separate consent. You also need to factor in up front that running a single scenario takes at least 3 to 5 pieces of content. Before adopting a tool, counting how many usable assets you have comes ahead of comparing tools.
The most common misconception is that buying MA will generate leads. Automation only handles the leads that come in; it doesn’t create inflow, so adopting it when monthly inflow is not even in the double digits turns it into an expensive email sender. Setting the threshold by gut feel and funneling dozens of leads to sales every month is also risky. Within a couple of months you hear 'another useless list,' and from then on the very term MQL gets ignored.

It took shape within the marketing tech industry rather than through any single founder.
Consider a hypothetical case. Company A makes industrial measuring equipment, with 140 employees and annual revenue of KRW 32 billion (≈ US$23,941,300). Leads downloading technical white papers from its website piled up at 180 a month, but the three-person marketing team managed them in Excel, so only a small fraction reached sales. Here is how they set up MA over six months.
- When Manager Kim on the marketing team opened the download list for the past six months, 1,080 entries, sales had actually contacted only 210 of them, and the rest were sitting untouched in Excel.
- Sales director Park insisted, 'We won’t take just anyone.' So the teams agreed to give 20 points for job title and company size and 30 points for a pricing-page visit, and to hand over a lead only once it scores above 60.
- They built a three-email scenario: a thank-you email on the day of the whitepaper download, a case study three days later, and a quote guide seven days later. With too little content, they split an existing proposal into four pieces to fill it.
- When the open rate stalled at 18% in the first month, Manager Kim changed the subject line to a field problem, such as 'Three Ways to Reduce Measurement Error,' and moved the send time to Tuesday at 9 a.m., raising it to 29%.
- Leads that didn’t respond were moved to a monthly newsletter and watched for two months. The 34 who reopened the materials automatically returned to the nurture scenario, and 9 of them led to sales conversations.
- Six months later, leads passed to sales rose from 35 to 62 a month and the close rate on sales conversations climbed from 22% to 41%. Director Park said, “This is good enough to adopt.”
