How to reduce spam score?
Smartlead’s email verification tool checks the validity of each email address in your list by performing several checks: syntax validation, domain DNS lookup, SMTP server verification, and detection of temporary or disposable emails. It also checks for catch-all domains and ensures emails aren’t listed on blacklists. Once the verification process is complete, Smartlead provides a report showing which emails are valid, invalid, or risky, allowing you to optimize your outreach.

Verifying emails ensures you're sending messages to real, active addresses, which improves inbox placement. Invalid emails and low-quality addresses can damage your sender reputation, leading to higher bounce rates and spam filtering. By cleaning your email list and removing these addresses, you increase the chances that your emails land in the inbox, not the spam folder. This leads to higher engagement rates, more opens, and better overall deliverability.
