Understanding Inbox Warmup

Understanding Inbox Warmup

Before ConvergeFlow sends cold emails from your inbox, we warm it up to build sender reputation.

What warmup does

Warmup sends a low volume of real emails between trusted accounts and automatically marks them as 'not spam'. This signals to Gmail and Outlook that your inbox is legitimate.

Duration

Warmup runs for 14 days by default. You can start campaigns before warmup completes, but higher deliverability is achieved after day 7.

Daily sending ramp

Days 1-3: 10 emails per day

Days 4-7: 30 emails per day

Days 8-14: 75 emails per day

Day 15+: 150 emails per day
