A Plain-English Marketing Glossary for Small Business Owners
Marketing has its own language, and if you didn’t grow up in it, the jargon moves fast. Deliverability, segmentation, DMARC, drip campaigns, MQL, suppression lists, these terms show up constantly in tools, proposals, and vendor conversations. If you don’t know what they mean, it’s easy to nod along and make expensive decisions based on incomplete information.
This glossary is built for small business owners who want to understand what they’re being sold, what their tools are actually doing, and what the metrics on their reports actually measure. No unnecessary complexity, just clear working definition of the terms that come up most in marketing, emails automation and website management.
Most the the terms here relate to email marketing and marketing automation, the area where jargon causes the most confusion and the most costly mistakes for small businesses. We will continue adding terms across SEO, web design, social media, and paid advertising as the glossary grows. If you come across a term that isn’t here yet, the contact page is the fastest way to ask.
