Your inbox is costing you clients & money.
Every hour an email sits unanswered is a potential deal gone. Hiring staff is expensive, slow, and error-prone.
Employee Cost is Draining You
Hiring someone just to manage emails costs $2,000–$5,000/month. They take breaks, miss emails, and make mistakes — that money goes straight to profit with Zylos.
Slow Replies = Lost Deals
78% of customers buy from the vendor who responds first. If you reply in 5 hours instead of 5 minutes, your competitor already closed the deal.
No One Watches at Night
Clients in New York email at noon — that's midnight in London. Without 24/7 coverage, you're gifting those leads to competitors who respond faster.
Spam Clogs Your Real Work
30–50% of business emails are noise. Your team wastes hours sorting through newsletters and promotions to find the emails that actually drive revenue.
One AI agent, total inbox control.
Zylos works silently in the background — classifying, replying, and surfacing leads so you never miss revenue.
