The four layers of a marketing technology stack (data, engagement, content and measurement), what joins them, when to build, buy or compose, and a procedure for choosing vendors on use cases, interfaces, data, consent and exit terms.
How companies use what they know about their customers to keep them: segmentation by recency, frequency and value, lifecycle marketing, loyalty programmes from points and tiers to paid memberships and coalitions, how retention and the Net Promoter Score are measured, and the rules on profiling and loyalty data.
How direct marketing reaches one named person or household and asks for a reply, how its response rates and tests work, what lists and preference services allow, and how the rules on calls changed in 2026, from the UK's TPS and the US Do Not Call Registry to France's move to prior consent.
Email marketing reaches people who chose to hear from you, on a list you own. Whether it works depends on three things: consent that meets each country's law, authentication that Gmail, Yahoo and Outlook now require from bulk senders, and messages relevant enough that readers stay subscribed.
