Definition
Software that automates repetitive marketing tasks (email sequences, social posting, lead nurturing) based on rules or triggers. A trigger is an event like a form submission or a completed job; the rule decides what message goes out next. It predates AI marketing but is increasingly powered by AI for content and decisioning.
What it looks like in practice
A pest control company sets three triggers. When a quote request comes through the website form, the system tags the lead by service type and sends a same-day quote confirmation, then a check-in two days later if no reply. When a quarterly treatment is marked complete in the job software, a different rule fires a reminder ninety days out with a booking link. When a customer's card fails, a third rule pauses all promotional sends so nobody gets a coupon while their invoice is overdue. The owner writes each message once; the triggers decide when it goes.
Why it matters
The value for a small business isn't the sending. It's that the sequence encodes decisions the owner would otherwise have to make one at a time. Once a trigger is defined, every lead of that type gets the same treatment, which makes the marketing predictable enough to actually improve. The tradeoff is drift: rules written for last spring keep firing after the service mix, pricing, or seasonality has changed, so messages arrive that no longer match the business. Automation also amplifies bad segmentation; one wrong tag and the whole list gets the wrong email. Someone has to audit the triggers periodically, the same way you'd review a lead nurture sequence.
