Everything You Need to Deliver

  • Intelligent send volume ramp-up that mimics human behavior
  • Realistic reply, open, and click patterns
  • Progress tracking with inbox placement rate monitoring
  • Daily warmup targets with configurable volume

Email Verification

Bad email addresses damage your sender reputation. Verify every address before you send — via API, CSV upload, or single lookup.

  • Syntax validation, domain/MX check, mailbox probing
  • Catch-all detection, disposable email detection
  • Batch processing with progress tracking
  • Export results as CSV for your CRM

Campaign Sequences

Build multi-step follow-up sequences that adapt based on recipient behavior. Send smarter, not harder.

  • Smart conditions: if_no_reply, if_replied_positive, if_replied_negative
  • Configurable delay windows between steps
  • Sentiment-based reply detection (positive/negative keywords)
  • Detailed sequence analytics with conversion funnel
