Sending product announcements without considering your audience is like writing a love letter and then addressing it “to whom it may concern” - Every week you'll receive a dozen emails from companies you know nothing about, telling you about some feature you don't understand, that was added to a product you don't use. People lament how email marketing has become less effective these days, but when reviewing some of these mails, it's not surprising. At Intercom, we encourage customers to send well-targeted messages, treating their userbase as distinct groups: active and inactive, with each group requiring personalized approaches. Active users should receive relevant updates tailored to their usage, while inactive users need a more nuanced approach, considering individual characteristics and behaviors.
