Overview

See how an ecommerce brand does email marketing: latest campaigns, send frequency and when it last emailed.

Know what your competitors send, without subscribing to a single newsletter. Signal by StackEnhance shows you a store's email marketing while you're on its website. Open a store, click the icon, and see: • When the brand last emailed • How often it sends, measured over the last 90 days • Its latest subject lines and send dates • How many of its emails Signal has seen, and since when • Its busiest send day and hour, its typical discount and the kinds of campaigns it runs • The same brand in its other markets, and a note when you're on a market Signal doesn't track yet • Similar brands to compare with Save a brand with the star and the next time you open it you'll see how many new emails it has sent since you last looked. Your saved brands stay in your browser. Signal follows the newsletters of 1,000+ stores, mostly in Sweden, Norway, Denmark, Finland and Germany. Each one has its own page on stackenhance.com, and a free account goes further back in time. Private by design • Works only when you click the icon. It can't see your other tabs or your history. • The site you're on is matched against our store list on your own device. The address never leaves your browser. • No account and no sign-in. Honest numbers Signal counts the marketing emails it has actually received. No open rates, no click rates, no guesses. Welcome, birthday and order emails are left out. Not tracking a store yet? Click "Ask Signal to track this brand". Only the site name is sent. Leave your email if you like, and we'll send you one email when we start tracking it, then delete your address. Made by Stack Enhance AB, Sweden.
