There's also live chat, an extra that's a nice way to let people reach out to you when they're stuck. You can talk to people on your site directly from Interakt, leading them through your app or helping them see exactly which of your products is best for them. Combine that with in-app messages and email campaigns, and you have everything you need to lead your users through the sales process.
Marketing automation platforms allow companies to deliver promotions on, say, flash sales, to small segments of the customer universe based on targeted campaign objectives, or revenue goals for a particular territory or population. AI and analytics tools either can or soon will be able to create predictive models that can drive even more revenue with fewer customers contacted per campaign, depending on the tool and to which CRM platform it connects.
