The record

Purpose: SendScale says its warmup service uses AI to warm email accounts automatically and build sender reputation for cold outreach.
Conversation simulation: SendScale says its AI sends unique emails between accounts, opens and scrolls through them, and replies using human-style language.
Spam rescue: When a warmup email lands in spam, SendScale says it automatically moves the message out, marks it important, and replies to it.
Diagnostics: The dashboard shows daily warmup sent and reply counts, spam versus inbox placement trends, and a readiness indicator.
Warmup duration: SendScale recommends a 14-day warmup period for new domains and says the dashboard indicates when it is complete.
Ongoing warmup: Warmup continues at a lower volume while campaigns run, according to SendScale, to help maintain sender reputation.
Email providers: SendScale says existing Google Workspace and Microsoft 365 inboxes can connect through OAuth.
Account management: SendScale says it can rotate connected accounts for load balancing and consolidate replies in its Master Smartbox.
Account limits: SendScale says Growth tiers allow unlimited sending accounts and that Gmail and Outlook accounts can be mixed.
Security and privacy: The privacy policy says database servers are located exclusively within the European Union and describes industry-standard security measures for personal data.
Privacy commitments: SendScale says it does not sell or rent personal data for marketing and that it does not sell, share, or rent customer contact lists to third parties.
Support: The pricing page lists general support tickets and priority support among plan benefits, but the opened page does not specify which tiers include each.
Intended users: The email warmup page names SDRs, agencies, founders, marketers, staffing agencies, growth teams, freelancers, and recruiters as audiences.
Price from: $3,528/mo
