Understanding IP Reputation ​

What is IP Reputation? ​

IP reputation is how much trust other email servers give to the IP addresses that send your emails. A good reputation means your emails are more likely to go to the inbox, not spam.

IP reputation depends on:

  • How often and how many emails you send
  • Spam complaints and bounce rates
  • Proper email authentication (SPF, DKIM, DMARC)
  • Quality of your email content

At OnePoundEmail, your emails share IP addresses with other users, so keeping these IPs trusted helps everyone, and equally, bad actors affect other users. This is why we take pride in our infrastructure and do the best we can do keep IPs clean.

Why IP Reputation Matters ​

Big email providers (like Gmail, Outlook, Yahoo) check IP reputation to decide if they accept your emails. Poor reputation can cause emails to be blocked or sent to spam.

OnePoundEmail works hard to keep IP reputation strong to improve your email delivery.

How We Protect IP Reputation ​

1. Monitoring and Restrictions ​

  • Block sending to invalid email addresses
  • Stop sending to unverified bulk mailing lists
  • Limit suspicious or spam-like sending behavior

2. Email Filtering ​

  • Automated tools scan emails for spam signals (no humans read your emails)
  • Check email format and authentication before sending

3. IP Rotation ​

  • If an IP has issues, we stop using it temporarily
  • Emails are sent from clean IPs to keep delivery smooth

4. Backup Delivery ​

  • If first delivery fails, emails are routed through alternate servers
  • Multiple attempts are made over 24 hours before bouncing

How You Can Help Maintain Good IP Reputation ​

  • Keep your email lists clean and updated
  • Always honor unsubscribe requests
  • Send emails only to people who asked for them
  • Use SPF, DKIM, and DMARC authentication correctly
  • Monitor bounce rates and fix problems quickly

What to Do If Emails Don’t Deliver ​

  • Check if emails are in recipients’ spam folders
  • Verify your SPF, DKIM, and DMARC records
  • Test your email with tools like mail-tester.com
  • Avoid spammy words or formatting in your emails
  • Check if the recipient’s email provider has strict filters
