Keep subject lines under 50 characters so they display fully on mobile devices. The sweet spot is 30–50 characters. On mobile, subject lines over 50 characters get cut off in most email apps.
Emojis can increase open rates by 25–45% when used sparingly and appropriately for your audience. One emoji at the start or end makes your email stand out in a crowded inbox without looking unprofessional.
