Some key principles include:

• Social proof: Showing that others trust or use your product to build credibility.

• Scarcity: Highlighting limited availability to encourage faster decision-making.

• Anchoring: Using reference points to make your offer seem more valuable.

• Reciprocity: Offering something for free (like a report or a discount) to trigger a sense of obligation.
  These principles, combined with data-driven insights, can help drive more meaningful results in your campaigns.
