What is sender reputation?

What is the sender reputation and why it is so important today?

🔎 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

💡 Why it is so important?

DMARC is an extension of existing email authentication methods like DKIM and SPF. It makes sure that no unauthenticated users will be able to send email from your domain, protecting your brand and the trustworthiness of your domain.

It's also an indicator used by ISPs to flag emails as spam or not. Having a DMARC set up for your domain will improve your overall email deliverability.
