My immediate first thought is...are emoji loving folks worth keeping? Not meant as an insult. But if your retention rate is up 50% with 18 year olds, and down 25% with 30+ers, is that good? My hangup is that it's a bank. As another so eloquently described, I prefer an ultra professional appearance. Money is important, and banking is ultra regulated. I want to feel they are on top of everything. Pizza places all started using emojis in communications to me. And that's ok, it's just pizza. But I don't want my doctor sending me an email with a crab and a skull.
