Email Warmup

Gradually ramp sending volume on new domains and IPs so mailbox providers trust you before you need to send at scale.

When to use this skill

• Setting up a new sending domain or subdomain
• Switching to a dedicated IP address
• Moving to a new email service provider (even with an existing domain)
• Resuming sending after a long period of inactivity (30+ days)
• Scaling up from low volume to high volume sending
• Seeing deferrals, throttling, or spam folder placement on a new domain
• An AI agent needs to send email and you haven't established sending history yet
