Three promises

01

Your data

  • Third-party keys, such as your Apollo key, are encrypted and only the last four characters are ever shown.
  • Team roles and permissions control who can send, bill and export.
  • Certifications: we list only those we hold. None are claimed today.
02

Your domain

  • Warm-up, several mailboxes per sequence, and a health score that pauses sending at critical bounce or complaint levels.
  • Help setting up SPF, DKIM and DMARC for each sending domain.
  • Dedicated IPs for high-volume senders.
03

Your buyers

  • An unsubscribe link on every marketing email and a do-not-contact list for outreach.
  • WhatsApp only for people who opted in.
  • An acceptable-use and anti-spam policy; accounts that break it are paused.
