Send daily price-drop digest emails for Amazon, Walmart and Google via ScraperAPI
Pull contacts, verify each address with BillionVerify, and continue to ScraperAPI — only deliverable addresses get through.
Why verify before the send
Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the ScraperAPI step removes that risk automatically — only deliverable addresses continue, the rest are flagged.
The workflow
BillionVerify — verification sits right before the send.
