Used For

• +**Your email campaigns bounce 10-15% and Gmail starts marking you as spam** → Clean lists before sending, bounce rates drop to under 2%
• +**Fake accounts flood your WooCommerce store during promotions** → Real-time blocking stops throwaway emails at signup
• +**Your sales team wastes time calling dead email leads** → Bulk validation flags bad contacts before they hit your CRM
• +Processes 100k emails in 45 minutes - no waiting overnight for results like some competitors
• +Email scoring (0-10) tells you which catch-all emails are worth keeping vs deleting

Best For

• >Your email bounce rate is above 5% and your marketing platform is threatening to suspend you
• >Fake signups are clogging your ecommerce site and skewing your conversion data
• >You're about to send to a big list and can't afford to tank your sender reputation

Not For

• -Solo creators sending under 2,000 emails per month — the free tier covers you, but paid credits add up fast for sporadic use
• -Companies wanting flat monthly pricing — this is pay-per-email credits that scale with your usage
• -Teams needing advanced workflow automation — it validates emails well but won't replace your marketing automation platform

Pairs With

• *Mailchimp (to clean lists before campaigns since Mailchimp's built-in validation is basic)
• *WordPress (blocks fake signups on contact forms and WooCommerce checkouts in real-time)
• *HubSpot (validates leads before they pollute your CRM with bad contact data)
• *ActiveCampaign (ensures your email sequences actually reach people instead of bouncing)
• *Zapier (automatically validates new signups from other tools before adding them anywhere)
• *Google Sheets (where you'll export the validation results to manually review the questionable ones)

The Catch

• !Credits cost around $0.007-$0.009 per email, so cleaning a 100k list runs about $700 one-time
• !Bulk processing can take longer than advertised 45 minutes when anti-spam systems add delays
• !Advanced integrations are limited — works great with WordPress and major platforms but custom setups need developer time

Bottom Line

Prevents your email campaigns from face-planting into spam folders by catching fake addresses before you send.
