Background info
Cold outreach success depends on email deliverability, and many businesses use Smartlead’s warmup feature to improve their inbox placement.
Smartlead users are typically B2B businesses running cold email campaigns, warming up their secondary or tertiary email addresses to improve sender reputation.
Most warmup email accounts are not actively monitored, making it difficult to engage with the real decision-makers behind them.
My goal is to bridge this gap by identifying the primary email addresses of businesses using Smartlead warmup, helping cold outreach campaigns reach actual decision-makers.
NOTE: This system is not for sale. This is made for Leadlake.co's internal use only.
The purpose
Automate lead identification by extracting primary email addresses from businesses actively engaging in cold outreach.
Eliminate wasted efforts by ensuring outreach emails are sent to the right contacts instead of unmonitored warmup accounts.
Streamline lead generation by integrating discovered email addresses directly into Google Sheets for easy access and tracking.
Prevent duplicate processing by automatically labeling emails that have already been handled.
The workflow
Monitor Gmail inbox for emails with the “warmup” label (these are Smartlead-generated warmup emails).
Extract the domain from the sender's email address (e.g., [email protected] → company.com).
Crawl the sender's website to find primary email addresses associated with real decision-makers.
Store extracted email addresses in Google Sheets, categorizing them alongside their corresponding domains.
Label processed emails to prevent duplicate handling, ensuring efficiency and accuracy.
This system ensures consistent, automated lead discovery for businesses engaged in cold email outreach. 🚀
