Reciprocity plays a crucial role in email marketing for several reasons:
1. Builds Trust: By consistently providing valuable content or offers, you can build trust with your subscribers. 2. Enhances Engagement: Subscribers are more likely to open and engage with emails from a sender who has provided them with value in the past. 3. Boosts Conversions: When subscribers feel they have received something valuable, they are more likely to reciprocate by making a purchase or taking another desired action.
