Mobile marketing can feel too close to personal space because customers use the same phone for family, work, payments, private conversations, and daily communication.
A promotional SMS can appear in the same inbox where the customer receives OTPs, delivery updates, bank alerts, and personal messages.
A push notification can light up the lock screen during work, study, meetings, meals, or rest time.
A WhatsApp promotion can enter the same chat app where the customer talks with family, friends, clients, or coworkers.
Repeated phone alerts can make the customer check the screen even when the message is only a sale update or product promotion.
Marketing notifications can become more irritating when they use sound, vibration, or banners on a device the customer keeps nearby most of the day.
