Irrelevant Content: One of the primary reasons for high unsubscribe rates is sending content that does not align with the interests or needs of your audience. Frequency: Sending emails too frequently can overwhelm recipients, prompting them to unsubscribe. Conversely, sending too infrequently can cause them to forget about you, resulting in surprise or irritation when they do receive an email. Expectations: If your emails do not meet the expectations set when users subscribed, they are likely to opt out. Poor Design: Emails that are difficult to read or navigate can frustrate recipients, leading to a higher unsubscribe rate. Spammy Content: Subject lines or content that appear spammy will not only cause unsubscribes but may also lead to your emails being marked as spam.
