ActiveHow Email Warmup Works
Your sending reputation builds daily, silently, while you focus on what matters.
Connect Your Inbox
Link your Gmail, Outlook, or custom SMTP account. We support unlimited accounts in parallel for faster scaling.
Automated Interactions
Our system exchanges emails with a network of warm, trusted inboxes. Emails are opened, starred, and replied to — exactly like a real human would.
Watch Your Score Rise
The daily send volume gradually increases (from 10 → 50+ emails/day) while your spam rate drops to 0%. Track every metric in real-time on your dashboard.
