We've recently introduced some new typography into TalkBox – specifically we've worked on increasing line heights to improve the appearance and legibility of type within emails. All new emails will apply the new typography automatically.
If you have an old template that uses the old typography and you'd like the new typography, take heart – there's an easy fix. Simply drag a new text block into your template and copy/paste your old text into the new text box. The type should automatically adjust to the new line heights.
Be careful, though, you may lose some custom formatting such as font colours, and you may need to reapply some styles.
