Email Hygiene lets you clean any address list before outreach. Upload a CSV with an email column, and the tool tags each address as valid, risky, catch_all, role_based, invalid, disposable, or unknown. Download only the clean, deliverable addresses to protect your sender reputation.

One credit = one qualified lead: a lead scored Hot (75+) or Warm (50–74). Cold leads, invalid emails and duplicates are free, and a single file is never charged more than 500 credits. New accounts get 500 free credits; Starter includes 2,500 leads a month and Scale 10,000. Unused plan credits reset each month; top-up credits carry over. Your balance is shown on the Billing page.

Leedrush supports CSV, Excel (.xlsx, .xls) and JSON. Files are checked for encoding (UTF-8 preferred), column structure and your plan's row limits when you upload.

Open the file in My Batches and use Export: CSV, Excel or JSON, all leads or only Hot and Warm. You can also push Hot and Warm leads to a connected CRM from the same page.

Every row is checked: the email for format and then deliverability with mails.so, phone numbers for format, duplicate emails are left out, and each company's own website is read (plus Apollo data if you connect your own Apollo key). DeepSeek AI then scores every lead 0–100 against your ideal customer with a one-line reason: Hot 75+, Warm 50–74, Cold below 50.

Go to Integrations in your dashboard. You can connect HubSpot, Pipedrive, GoHighLevel, ActiveCampaign, Mailchimp, Reply.io, Outreach.io or Zapier with an API key or access token. Once connected, push Hot and Warm leads by hand or automatically after each file.

Yes. Starter and Scale can be cancelled at any time under Plans & Pricing → Manage billing. Your plan stays active until the end of the period you paid for, and you won't be charged again.
