Yes, using ActiveCampaign Webhooks + Zapier/Make/n8n with our /api/v1/verify endpoint.
ActiveCampaign enforces a strict 1.0% hard bounce review threshold across all automated Customer Experience Automation (CXA) deals, site tracking events, and drip sequences. When unverified webinar leads or legacy CSV imports trigger 550 User Unknown rejections inside ActiveCampaign, Postmark/SparkPost upstream gateways throttle your workspace sending speed.
Connecting KaijuVerifier to ActiveCampaign via POST /api/3/contact/sync or automated webhook actions tags every incoming contact with kaiju_valid, kaiju_catchall, or kaiju_invalid before your first welcome automation fires — keeping your ActiveCampaign bounce ratio under 0.20% while eliminating wasted contact-tier fees.
