What does your marketing stack look like right now?

An honest question, and we would rather hear the real answer than the tidy one. Most stacks are not designed, they accumulate — a CRM someone picked four years ago, an email tool bought for one campaign, a form builder that came free with the website, and a spreadsheet quietly holding the whole thing together. So: what are you actually running? Where does something get typed in twice? Which part breaks when the person who set it up is on holiday? And which tool would you drop tomorrow if the thing it does lived somewhere else? Genuinely useful to us, and usually useful to whoever reads the thread next and recognises their own setup in it.
