Sender reputation in email marketing refers to the perception that email service providers (such as Gmail, Yahoo, Outlook, etc.) have of the email sender, based on various factors such as sending frequency, content quality, subscriber engagement, complaint rates, etc. A good sender reputation is crucial to ensuring the deliverability of emails into recipients' inboxes rather than into their spam folders. Senders with a poor reputation can have their emails blocked or filtered as spam, which can seriously affect the effectiveness of their email marketing campaigns. To maintain a good sender reputation, it's important to follow good email marketing practices, monitor performance statistics and respond quickly to any problems.
