Using Welcome Mat’s ‘Instant Landing Page’ feature you can lock the signup page in place so users can’t scroll down without signing up. A full screen minimalist landing page like this works wonders for activation rates. In some cases we’ve seen 10%-30% conversion to email signup! Be sure to test different variations of design and copy as it can make a big difference to performance. If you find this too intrusive for the first visit, it can still be very effective if shown on visit 2 or on the 2nd page visited.
