Targeting the incorrect range can lead to several issues: - Low Engagement: If your emails are not relevant to the recipients, they are less likely to open, read, or click through them. - Higher Unsubscribes: Irrelevant emails can annoy recipients, leading them to unsubscribe from your mailing list. - Poor Deliverability: Consistently low engagement rates can signal to ISPs that your emails are spam, affecting your overall deliverability. - Wasted Resources: Time and resources spent on creating and sending emails will be wasted if they don't reach the right audience.
