TestSubject is a simple tool for testing how your email subject line and sender name look on the most popular mobile devices and email clients*. Just copy and paste your text and you’ll get instant previews.
This embarrassing subject line could've been avoided with ZURB's tool: http://imgur.com/r1oDxTc
The last word was supposed to be "cupom" ("coupon" in Portuguese); it became "anus" instead.
@dredurr It's important to see how your subject line, sender name, and preheader text all work together to influence someone to open your email. It's not purely about length. Also, some of the latest research indicates that depending on your industry, longer subject lines can work better.
@mrcodella Your statement sounds more like from a sales-y cold email point of view.
Subject line, sender name, and preheader only matter if your recipient never received an email from you ever.
If I receive a email from a trusted source I will open it period. 🤓
I try to keep subject lines to less than 100 characters because 60% of the people in N. America view email on mobile first. If you keep it short, it doesn't matter if it is mobile or desktop.
