  • Deliverability (Emails land in spam)
  • Engagement rates (Low opens/clicks = poor sender reputation)
  • ROI (Wasted spend on uninterested leads)

Focus on attracting the right subscribers—people who genuinely want your content—instead of chasing vanity metrics.

Tools to Capture and Verify Leads

1. Optimized Opt-In Forms

  • Landing pages (Dedicated signup pages)
  • Exit-intent popups ("Wait! Get X before you go.")
  • Embedded forms (Blog sidebar, footer CTAs)

2. No2Bounce’s Real-Time Verification API

Stop invalid emails at signup with instant email validation, preventing:
❌ Typos (Gmaill.com → Gmail.com)
❌ Disposable emails (TempMail, 10MinuteMail)
❌ Spam traps & risky domains

Result? A cleaner list from day one.

Avoiding Spam Traps in New Lists

Spam traps are honeypot emails used by ISPs to catch spammers. Hitting them can destroy your sender reputation.

How to Avoid Them:
✔ Never buy or scrape lists (Only use opt-in leads)
✔ Use double opt-in (Confirms real users)
✔ Clean lists regularly (Remove inactive subscribers)
