Of 700 different emoji domains, people love their cats, hearts, watermelon, rockets, smileys, etc ...

Also, are domains not $5-$10 say? ~$2000 on 'tiny projects'?

...ahh, read the full breakdown, it is approximately something like that, which seems crazy, but I dunno, guy has some money to spare and went nuts with the project and sold a bunch of accounts. (also weird, but tiktokers susceptible to random stuff I guess)

While reading the post, I realised that it was a really great idea to say the least but I was very shocked when I saw that OP earned $18000 off the project. Although, one down-side of using email addresses which contain emojis is that some email clients do not support them.
