Sendscale is an all-in-one cold email software that combines AI automation, lead generation, and email infrastructure in a single workspace. Just tell Sendscale what your business does or drop your URL and the AI finds qualified leads from a 450M+ B2B database, loads them into a campaign, drafts your email sequences, and gets everything ready to send. No stack to assemble, no separate prospecting tool, no manual warmup.

Unlike most email outreach platforms that leave deliverability up to you, Sendscale handles the hard parts automatically: domain warm-up, DKIM/SPF/DMARC configuration, bounce management, spam complaint handling, and real-time inbox health monitoring. Every connected account gets free automated warmup from day one.

Sign up free and get 1,000 SmartSearch lead credits, a 48-hour pre-warmed inbox to test sending immediately, and an AI sales agent that's active from your first login. Scale up with transparent volume-based pricing, pay for the emails and leads you actually use, not per contact in a database.

Built for founders running their first outbound campaign, SDRs scaling across hundreds of inboxes, and agencies managing outreach for multiple clients. Sendscale is the cold email and lead generation tool that grows with your operation.
