Marketing Automation
Marketing automation is software that triggers marketing actions — emails, texts, lead scoring updates, ad audience syncs — based on rules and customer behavior, without a human sending each one manually.

How marketing automation works
Marketing automation runs on a simple structure: a trigger, a condition, and an action. The trigger is an event — a form fill, a page visit, an email open, a set number of days since last contact. The condition filters which contacts qualify — for example, only leads tagged "trial signup" who haven't booked a demo. The action is what happens next: send an email, add a tag, notify a rep, or move the contact to a new list. Chained together, these rules replace what would otherwise be a person manually checking a spreadsheet and sending individual emails.
Most platforms support branching logic, so a single automation can send different follow-ups depending on whether a contact opened the last email, clicked a link, or did nothing at all.
Example
A contact fills out a "request a quote" form. The automation waits two hours, sends a pricing email if no reply comes in, tags the contact as "quote requested," and — if the contact opens that email twice without replying within three days — alerts the assigned rep to call instead of email.
Why teams use marketing automation
Manually tracking hundreds or thousands of leads through a nurture sequence isn't realistic past a small handful of contacts. Marketing automation lets a small team run consistent follow-up at a volume that would otherwise require hiring more people, and it removes the risk of a lead going cold because no one remembered to send the next email.
It also creates a consistent record: every automated touch is logged on the contact, so a rep picking up a lead later can see exactly what content the prospect already received instead of guessing.
Marketing automation vs. drip campaigns
A drip campaign is one specific type of marketing automation — a fixed sequence of messages sent on a schedule regardless of behavior. Marketing automation is the broader category, and it includes drip campaigns alongside behavior-triggered actions like lead scoring updates, list segmentation, internal notifications, and ad platform syncs that don't involve sending the contact anything at all.
What marketing automation typically triggers
Common actions include enrolling a contact in an email sequence, updating a lead score, assigning a lead to a rep based on territory or workload, adding a contact to a retargeting audience, and creating a task for a human to follow up manually when automation alone isn't enough — such as a high-value lead who needs a phone call instead of another email.
