Several factors can lead to user frustration in the context of email marketing. These include:
Overwhelming Frequency: Sending emails too often can lead to inbox clutter and frustration. Irrelevant Content: Emails that do not align with the recipient's interests or needs are often ignored or marked as spam. Complex Unsubscribe Process: Making it difficult for users to opt-out can lead to negative feelings and complaints. Poor Design and Usability: Emails that are hard to read or navigate can frustrate users. Lack of Personalization: Generic content that does not speak to the individual can cause disengagement.
