Custom preview text (aka preheader) enters the editor!
This feature is available for accounts on the new Google Cloud infrastructure. Your email’s preview text is one of the first things your users see. Also called the ‘preheader,’ it’s the small block of text which displays next to or underneath the subject line, and gives users incentive to open and read: Before, you could define this in Customer.io, but only with some code-based workarounds. Now, you can easily add it as part of your email-composition workflow. Technically, this is the first piece of text in your email body. Sometimes, this is OK— if your content begins right away, and is short enough to be a summary. But you might have text like ‘Is this email not displaying correctly?’, code, or other administrative details at the top of your email, and this doesn’t make for a great preview of your email’s content!
