Most cold email tools charge per credit to unlock email addresses and charge again for contact storage above a few thousand. You get 50,000+ verified leads every month included, with unlimited contact storage so you stop deleting old leads to free up room.


New mailboxes require 4 to 8 weeks to warm up before you can safely send. Pre-warmed mailboxes are ready when you sign up, so you can launch real campaigns in days without burning your sender reputation.
Cold email has 15+ technical settings most teams never should learn. DKIM, DMARC, warmup pacing, suppression lists, sending limits, sequence design, deliverability monitoring. SmartAssistant handles all of it. You describe what you want, it takes real actions against your live account data. Not a chatbot or a UI button, an actual assistant that does the work for you.

Teams ship their first campaign in 15 minutes instead of weeks.
