I understand. So, we will be able to look into this matter should we get a client (one of our customers currently using the TalkTalk domain) to inform us about this matter. Alternatively, on your end, I will suggest for you to check on the following steps:
1) Check Your IP Reputation: Use online tools like MXToolbox, SenderScore, or Talos Intelligence to check the reputation of your mail server's IP address. This will help you understand if your IP is blacklisted or has a poor reputation.
2) Request Delisting from Blacklists: If your IP is listed on any blacklists, follow the procedures to request delisting. Each blacklist has its own process, which usually involves filling out a form and providing information about your mail server and practices.
3) Improve Email Practices: Ensure that your email practices comply with best practices to improve your reputation:
- Use SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate your emails.
- Regularly clean your mailing list to remove inactive or invalid email addresses.
- Monitor bounce rates and complaints, and take action to address any issues.
4) Monitor Feedback Loops: Sign up for feedback loops with major ISPs. This will help you receive notifications when users mark your emails as spam, allowing you to take corrective action.
Thanks,
