Yes, bounces and complaints from other email push users can affect your email deliverability. Email service providers (ESPs) monitor sender reputation based on various factors, including bounce rates and complaint rates. High bounce rates indicate that your email list may contain invalid or outdated addresses, which can harm your sender reputation. Similarly, a high complaint rate (users marking your emails as spam) signals to ESPs that recipients don’t want your emails, leading to potential blacklisting or delivery issues.
For example, if you send an email campaign and 10% of the recipients mark it as spam (complaint), ESPs like Gmail or Outlook may flag your domain or IP as a potential spam source. This can result in future emails being delivered to the spam folder or blocked entirely.
To maintain good deliverability, use email verification services to clean your list and ensure high engagement. If you're using cloud-based email services, consider leveraging Tencent Cloud's email delivery solutions, which provide tools for email authentication (SPF, DKIM, DMARC), real-time monitoring, and reputation management to help optimize deliverability and reduce bounces or complaints.
