The Hidden Problem
Most AI SDRs are just spam machines
Any AI can write a thousand cold emails before lunch. None of it books a meeting if it lands in spam. The hard part was never writing, it's reaching a human. That's the part every other AI SDR skips.
Your AI SDR Is Filling Spam Folders
It fires off 100 perfectly-written emails. You refresh obsessively. 15 opens. Maybe 2 replies if you're lucky. The other 83 vanished into spam folders you'll never see, and torched your domain on the way out.
Smart Warm-Up + List Cleaning = Protected Domain
1 in 5 cold emails land in spam (Mailshake 2025 Report). Smart warm-up gradually builds trust with inbox providers over 21 days. Automatic list cleaning removes invalid emails, spam traps, and dead accounts before they crater your reputation.
87% Inbox Placement vs. Industry 60-70%
Real-time monitoring shows exactly where your emails land, updated hourly. Catch problems within 2 hours, not 2 weeks. Multi-inbox rotation protects you when one account goes down. Your campaigns keep running with zero interruption.
THE DELIVERABILITY ENGINE
Three features that make the SDR loop actually work
Warm-up, list cleaning, and live monitoring working together so every email your AI SDR sends reaches a human inbox, not a spam folder.
Smart 21-Day Warm-Up
Your AI SDR sends cold email all day long. Without a warm inbox, those emails hit spam. FirstSales runs a 21-day warm-up that mimics genuine human behavior across Gmail, Outlook, and every major provider, building sender reputation before your first campaign fires.
Days 1-7 Low volume with positive engagement signals
Days 8-14 Gradual increases, reputation monitored continuously
Days 15-21 Full sending capacity, protected reputation
Result 87% inbox placement vs. the 60-70% industry average
Auto List Cleaning Before Every Send
The AI SDR scrapes the web to build your list. Before it sends a single email, FirstSales strips every invalid address, spam trap, and dead inbox from that list automatically. Competitors charge +$47/mo for this. We include it, because a bounced email is a domain reputation you cannot afford to lose.
Invalid syntax removed before the first send
Spam traps caught protects against blacklists
Inactive accounts filtered out automatically
Result bounce rates under 2%
Real-Time Deliverability Monitoring
See exactly where your AI SDR's emails are landing, refreshed every hour. If inbox placement dips, you catch it within 2 hours, not 2 weeks, and get a plain-English fix before the campaign burns your domain.

Custom AI Instructions generate personalized outreach for every contact. Auto Learning improves copy as replies come in.
