About
We believe cold email is broken
Generic tools blast thousands of identical messages from shared infrastructure. Deliverability tanks. Domains get burned. Agencies lose clients.
The problem
Most email tools treat deliverability as an afterthought. They cram hundreds of users onto shared IPs, offer zero campaign isolation, and call it “scale.” The result is predictable: spam folders, blacklists, and burned domains.
Our approach
Arcsend was built from the infrastructure up. Every campaign runs in its own sandboxed environment. AI writes personalized copy that passes the human test. Smart warmup builds reputation before you go full volume.
Team
Built by people who've done this before
Our team includes ex-engineers from Mailgun, Sendgrid, and Apollo. We've spent years building the infrastructure that powers billions of emails. Now we're applying that expertise to outbound.
Principles
What we stand for
Deliverability over volume
We'd rather you send 1,000 emails that land in the inbox than 100,000 that hit spam. Every feature we build optimizes for placement first.
Privacy by default
Your data stays yours. Complete campaign isolation means one client's activity never touches another's infrastructure.
AI as copilot, not autopilot
Our AI generates and suggests. You review and approve. The human stays in the loop because outreach is a relationship, not a broadcast.
