In their own words
SendScale Email Warmup
SendScale Email Warmup is a service for warming email accounts and building sender reputation for cold outreach. It connects Google Workspace and Microsoft 365 inboxes through OAuth, then uses AI to exchange unique messages between accounts in a private network SendScale says contains more than one million inboxes. The service says its system opens and scrolls through messages and replies in human-style language. If a warmup email lands in spam, SendScale says it moves the message out, marks it important, and replies. A dashboard tracks daily sends and replies, spam-versus-inbox placement trends, and readiness. SendScale recommends 14 days for new domains and says the dashboard indicates when warmup is complete; warmup can continue at lower volume while campaigns run. The service also describes account rotation for load balancing and a Master Smartbox for consolidating replies. Its free plan includes pre-warmed inboxes, warmup tools, in-product conversational guidance, and campaign access. Paid plans start at $28/mo billed annually. The privacy policy places database servers exclusively in the European Union and describes industry-standard security measures.
