🔎 What is the sender reputation?

Sender reputation refers to the trust  "score" given by ISPs (Internet Service Providers) to domains and IPs that send emails. The higher it is, the higher will be the deliverability (i.e. inbox placement of the outgoing emails). If it's low, ISPs will consider your domain/IP as suspicious and your emails will land in spam.

Sender reputation is affected by:

• The history of the sending domain
• The bounce rate of the sender
• The authentication protocols used (SPF, DKIM, DMARC, etc.)
• Eventual spam complaints or spam traps triggering
