Email Batching
Limiting email to three times per day reduces stress and distraction significantly.
The Principle
Most people check email far more often than they need to — about 15 times per day on average. Batching email into a few dedicated windows reduces the constant micro-interruptions that fragment your focus and elevate your stress throughout the day.

Key Statistic
Limiting email to 3×/day reduces stress (d = 0.45) and distraction (d = 0.51) [19]
What The Research Shows
Kushlev & Dunn (2015) conducted a within-subjects RCT (N = 124): limiting email to 3×/day reduced daily stress (d = 0.45) and distraction (d = 0.51) compared to unlimited checking [19]. This is the strongest experimental evidence for email batching. Mark, Voida & Cardello (2012) found workers cut off from email for 5 days showed lower task switching and lower physiological stress via heart rate variability [20]. Mark et al. (2016) found email batching was associated with higher perceived productivity but not lower stress in an observational design [21]. Fitz et al. (2019) extended the batching principle to all smartphone notifications [22]. Limitation: Kushlev & Dunn had a relatively small sample and short duration.

Common Myths
Myth: 'You should respond to emails immediately to stay on top of things.' Reality: Constant email checking increases stress without improving responsiveness. Batching into 2–3 dedicated windows is more effective [19][20].

How Aftertone Applies This
Aftertone allows users to create dedicated 'Communication Batch' blocks for email and messages, separate from deep work blocks. The app can suggest optimal email windows based on your schedule and remind you to batch rather than check continuously.
