Used For

• +**Your email bounce rate hit 8% and your ESP sent a scary warning email** → Clean lists before sending, bounce rate drops to under 2%
• +**Half your signups are fake emails breaking your onboarding sequences** → Real-time widget catches fakes at signup, only real users get through
• +**Spending 2 hours manually validating prospect lists before cold email** → Bulk upload CSV, get clean list back in minutes
• +Catches catch-all domains that accept any email - flags risky addresses other tools miss
• +Widget + reCAPTCHA combo only verifies human signups - saves money on bot traffic

Best For

• >Your email campaigns are bouncing 15%+ and Mailchimp is threatening to suspend you
• >Getting flooded with fake signups from disposable emails like 10minutemail.com
• >Sales team manually checking if prospect emails are real before cold outreach

Not For

• -High-volume senders doing 1M+ emails monthly - you need enterprise-grade tools with SLAs
• -Teams sending under 100 emails monthly - even $7 for 1,000 credits is overkill vs free alternatives
• -Anyone needing advanced enterprise features like A/B testing integration or custom reporting

Pairs With

• *Mailchimp (to clean lists before campaigns so you don't get suspended for high bounces)
• *HubSpot (validates leads before they enter your nurture sequences)
• *Klaviyo (prevents fake signups from breaking your e-commerce email flows)
• *Zapier (automatically verifies new signups from forms before adding to your CRM)
• *Google Sheets (upload messy prospect lists, download clean ones)
• *Your signup forms (widget catches fake emails before they pollute your database)

The Catch

• !Only 200 free credits to test - too small if you have a big list to validate upfront
• !Catch-all detection might flag some valid but risky emails, requiring manual review
• !No mention of handling server delays that temporarily block verification attempts

Bottom Line

Stops your marketing emails from bouncing and getting you blacklisted by Gmail.
