The Real Cost of Hiring
In Phoenix, a competent executive assistant costs $45,000-$75,000 per year in salary. But salary is not the real number. Add employer payroll taxes (7.65%), health insurance ($5,000-$15,000/year), PTO (10-15 days), equipment, software licenses, and office space. The fully loaded cost of a full-time assistant is $55,000-$100,000 per year.
Then there is the hiring process itself: job postings, interviews, background checks, and the 2-4 weeks of training before they understand your practice, your clients, and your communication style. If they quit — and turnover for administrative roles is roughly 25% annually — you start over.
AssistantAI costs $199-$500 per month ($2,388-$6,000 per year) for email management. No hiring. No training. No turnover. No benefits. It starts working within 48 hours.

What a Human Assistant Does Better
Let's be honest about where humans win. A great executive assistant does far more than email. They manage your calendar with nuance, coordinate complex multi-party scheduling, handle physical mail and packages, run errands, prepare for meetings with contextual judgment, manage travel logistics, and serve as a gatekeeper who understands your priorities intuitively.
If you need a full-spectrum assistant who handles your entire professional life, hire a human. No AI replaces that — not yet, and maybe not ever for certain tasks. A good EA is a competitive advantage.
Why Email Is the One Task AI Handles Well
Email is text-based, asynchronous, and pattern-heavy. The vast majority of professional email falls into repeatable categories: scheduling requests, status updates, information requests, follow-ups, and routine correspondence. These patterns are exactly what AI excels at.
AssistantAI reads incoming email, classifies it by priority and type, drafts a response using your voice profile and practice context, and puts it in your approval queue. You review each draft and tap approve. Nothing sends without you. For an attorney spending 2 hours per day on email, that drops to 15 minutes of review time.
The Hybrid Approach
Some of our clients have executive assistants AND use AssistantAI. The EA handles calendar, travel, physical tasks, and phone calls. AssistantAI handles the email inbox. This frees the EA to focus on higher-value tasks instead of spending half their day processing email — which makes them more effective and more satisfied in their role.
For solo practitioners and small firms where hiring a full-time assistant is not financially viable, AssistantAI handles the single biggest time drain — email — at a price point that any practice can justify.
The Math
A professional billing $300/hour who spends 2 hours per day on email loses $600 in potential billable time daily. That is $156,000 per year. AssistantAI reduces that to 15 minutes of review time, recovering roughly $525 per day in billable capacity. At $199/month, the ROI is not close. Run the calculation for your practice.
