Domain names need to render the same way everywhere to work.
I send out a weekly newsletter matching podcasters with guests for their shows. (If you don’t subscribe, you should.)
The newsletter is powered by MailChimp, and the service has an easy system for inserting emojis in the subject line of your email. I imagine having an emoji or two draws attention to the subject line. For this week’s email, I included a megaphone emoji.
When the email showed up in my Gmail inbox today, the subject line looked like this:
That’s what it looked like in MailChimp, too. Then I opened the email and the subject line looked like this:
If I look at the email on the Gmail app on my iPhone it looks different again:
It’s a megaphone in all three examples but they all look different. This sort of inconsistency is OK for email marketing, but not for domain names.
This is just one of the reasons I believe emoji domain names will remain just a niche marketing gimmick.
