Saleshandy email verification with BillionVerify
Saleshandy is a cold email outreach platform that helps sales teams automate personalized email sequences, track engagement, and scale prospecting without landing in spam. Because cold outreach starts with no prior relationship, list quality is the single most important factor in deliverability and reply rates.
Why verify before the send
Cold email to unverified addresses is a fast path to high bounce rates, which erodes your sending domain's reputation and triggers spam filters for every subsequent email you send. BillionVerify screens prospect lists before they are loaded into Saleshandy, removing invalid, disposable, and catch-all addresses so your sequences reach real decision-makers and your domain stays healthy.

How it works
- 1
Export your prospect list or connect your lead source to BillionVerify via the REST API or n8n.

- 3
Receive a per-address status and a cleaned list with invalid records removed or flagged.
- 4
Import only verified addresses into Saleshandy as contacts or leads.
- 5

When to use this
Scrub prospect lists before importing to Saleshandy
Upload your prospect CSV to BillionVerify before importing into Saleshandy. Remove invalid, disposable, and risky addresses from the list so every sequence you launch starts with a deliverable audience.
Verify leads from enrichment tools in real time
When prospect emails come from data enrichment tools or scraped sources, pipe them through BillionVerify via the REST API before they reach Saleshandy. Filter out unverifiable addresses automatically to protect your cold outreach reputation.
FAQ
Why is email verification especially important for cold outreach?
Cold email contacts have never opted in, so prospect data is often lower quality. A high bounce rate on cold sends can blacklist your sending domain, harming not just future cold campaigns but also transactional email delivery.
Can I verify addresses in real time as I find prospects?
Yes. BillionVerify's REST API lets you verify individual addresses programmatically, so you can integrate verification into any prospecting workflow or CRM enrichment step before contacts reach Saleshandy.
What is a catch-all address and should I include them in Saleshandy?
Catch-all domains accept email for any address, so you cannot confirm a specific address is valid. For cold outreach, sending to catch-all addresses carries risk. BillionVerify flags them so you can make an informed decision.
