What is Sender score?

Sender score is a numerical representation of a sender's reputation in email marketing. It is used by internet service providers to assess the trustworthiness of an email sender. Maintaining a high sender score is essential for achieving good deliverability rates and ensuring that marketing emails reach recipients' inboxes rather than being marked as spam.

1. Reflects the reputation of a sender's IP address for email deliverability.
2. Maintains a positive sender score to avoid spam filters.
3. Ensures consistent email delivery to recipients' inboxes.

Reputation Management: A high sender score is crucial for maintaining a positive sender reputation. Email service providers (ESPs) use sender scores to assess the sender's email sending practices.

Inbox Placement: A good sender score increases the likelihood of emails landing in recipients' inboxes rather than being filtered into spam folders.

Email Deliverability: Sender scores are a key factor in determining overall email deliverability rates. A positive sender reputation is associated with trustworthy and legitimate email senders.

High Bounce Rates: Excessive bounces, both hard and soft, can negatively impact sender scores. Regularly clean email lists to remove invalid or inactive addresses.

High Complaint Rates: If recipients mark emails as spam, it adversely affects sender scores. Provide clear opt-in options, relevant content, and easy opt-out processes to minimize complaints.

Consistency in Sending Practices: Abrupt changes in email sending patterns or sudden spikes in volume can be viewed negatively. Maintain a consistent and gradual approach to sending emails.
