AI Email Assistant Cost Comparison for Contractors

A $297 per month managed AI email assistant pays for itself if it gives a contractor back about four hours a month: $297 divided by a $75 hourly value is 3.96 hours, using the $75 hourly rate in alfred_'s ROI calculator. Software tools cost far less, such as Superhuman at $30 a month, but you set them up and run them yourself, and a human executive assistant costs $60,000 to $120,000 a year fully loaded. Both of those pages come from alfred_, which sells its own AI email assistant, so treat the figures as a seller's numbers.

Quick version

• The $297 per month figure is the price this article tests, with a setup fee on top. Riot Digital publishes this site, so I am an interested party. Confirm current numbers on the Riot Digital pricing page.
• Before setup, $297 a month breaks even at about 0.9 hours of work recovered per week at a $75 hourly value. The math is below.
• Cheaper software runs from about $7 to $36 a month for sorting and suggested replies. It does less of the work for you.
• A custom build or a human hire costs far more up front or per year than the managed plan.
• The premium is worth it only if you will use the hours you get back. In my view, that is the real test.

What each option costs

This table repeats published prices from sellers. Annual figures are my arithmetic, shown in each cell.

One more reference point: Majordomo's own guide says most AI email tools cost $25 to $50 a month. Majordomo sells a $9 tool, so it has a reason to call that range expensive.

What the cheaper tools do and do not do

Most low-cost tools work inside your inbox. They sort, filter, and suggest. For example, Gmail's Smart Reply suggests three short responses. That helps with quick answers. It does not chase a client who never replied, and it does not book the estimate.

A managed service is a different kind of purchase. Riot Digital describes its product as an AI employee that handles email, calendar, and follow-ups. The AI Employees page lists what that covers. Riot Digital sets it up for you, which is part of what the extra money pays for.

My take: if your only problem is a messy inbox, a $7 to $30 tool is probably enough. If your problem is missed follow-ups and appointment back-and-forth, software that only suggests replies leaves most of that work on your desk. This is my judgment, not a sourced fact.

How many hours can you get back

The sourced numbers are about office workers in general, not contractors. Treat them as a rough starting point.

• McKinsey research puts the average knowledge worker at 28% of the workweek on email, roughly 11 hours per week. That is alfred_'s summary of the research.
• A mid-range AI assistant that cuts email time by 30% saves approximately 3.3 hours per week. The arithmetic checks out: 11 hours times 30% is 3.3 hours.
• Independent benchmarks cited by alfred_ show a 30% to 60% cut in active email time on high-volume inboxes of 50 or more messages per day. Again, the page belongs to a seller.

My take: many contractors are on job sites, not in an inbox all day, so the 50 messages per day case may not describe you. Count your own messages for a week before you trust any of these percentages. That is an opinion, not a finding.

Break-even math

Start with the formula. Halo Technology Lab, a UK firm that sells automation consulting, gives it as Annual ROI = ((Annual Savings minus Annual Cost) divided by Annual Cost) times 100.

Next, pick an hourly value. The $75 rate is from alfred_'s calculator. Your own rate may be higher or lower. The same page says to divide your gross annual salary by 2,080 to get a base hourly figure. An owner who does not pay themselves a salary can still estimate what an hour of billable work earns.

Here is a made-up example, not real data. It uses the $75 rate, the 3.3 hours per week from the table above, and the $297 monthly price. It leaves out setup because I have no sourced setup figure.

The break-even point is $3,564 divided by $75 times 52, which is $3,564 divided by $3,900, or about 0.9 hours a week. Add your setup fee to the cost side and the break-even moves up a little. Halo says well-chosen automations typically deliver 200% to 500% ROI, so the first row sits inside that range and the second falls below it.

Compare that with a $30 tool. At a $75 hourly value, $30 divided by $75 is 0.4 hours, or 24 minutes a month. It is much easier to clear that bar. The question is how much work it takes off your plate once you clear it.

A caution about the big numbers you will see elsewhere. alfred_'s calculator claims roughly 75x return on a $25 per month tool and over $90,000 a year in savings at $300 per hour. Those are marketing figures from a seller, and the page itself is built to promote the purchase. I would not plan around them.

If you want a floor before you buy anything, Halo suggests a process should consume at least 5 hours per month to justify automating it. Email and follow-ups usually clear that for a small contractor, but check yours.

Versus hiring a person

The human option is the most expensive one in the table. A human executive assistant costs $60,000 to $120,000 per year fully loaded. At the low end, $60,000 divided by the $3,564 yearly managed cost is about 16.8, so the person costs nearly 17 times as much.

That comparison is not fair in every case. A person can show up at a job site, call a supplier, and handle problems nobody planned for. alfred_ claims an AI assistant handles 80% to 90% of the same email work as a human assistant, and I treat that as a vendor claim. The honest comparison is email, calendar, and follow-ups only, and a full-time hire is probably more than most small contractors need.

Versus building your own

A custom build is a real option, but it is mostly a poor fit for a small contractor. Appwrk, which sells AI email assistant development, puts MVP builds at $8,000 to $12,000 and enterprise-grade builds at $30,000 to $48,000. At the low end, $8,000 divided by $3,564 is about 2.2, so a basic build costs over two years of the managed plan. You would also still need to maintain it. Appwrk says a typical SaaS build takes 6 to 10 weeks, which is a long time to wait.

When the premium is and is not worth it

In my view, the $297 plan makes sense when:

1. You lose leads or jobs because replies and follow-ups go out late.
2. Calendar back-and-forth takes real time each week.
3. You will spend the hours you get back on billable work or on time off.
4. You would rather pay someone to set it up than spend a weekend on it.

It probably does not make sense when your inbox is light, when you only need sorting, or when you enjoy tinkering and would happily run a $9 tool. This is my judgment, not a sourced fact.

A simple way to test it

• Track your email, scheduling, and follow-up time for one week.
• Multiply those hours by 52, then by your own hourly value.
• Compare the result with 12 times the monthly price, plus setup.
• Ask any vendor what happens if the hours do not materialize.

If the numbers hold up with your own figures, a managed plan is easier to defend. If you want to run your numbers against Riot Digital's setup fee and monthly price, the pricing page is the place to start, and you can Book a call if you want to talk through whether it fits your business.

Frequently asked questions

Is a $297 per month AI email assistant worth it for a small contractor?

It can be. At a $75 hourly value, $297 divided by $75 is 3.96, so it breaks even at about four recovered hours a month before setup. Whether you actually recover those hours depends on your inbox and how much follow-up work you do.

How much do cheaper AI email tools cost?

Published prices run from $9 a month for Majordomo to $7 to $36 for SaneBox and $30 for Superhuman. Majordomo, alfred_ and the other sellers behind those pages have reasons to favor their own prices, so check each vendor directly.

How much does a custom-built AI email assistant cost?

Appwrk, a company that sells AI email assistant development, says MVP builds typically cost $8,000 to $12,000 and enterprise-grade builds $30,000 to $48,000. That is a one-time build cost, and it does not include maintenance.

How do I calculate ROI on an AI email assistant?

Use Annual ROI = ((Annual Savings minus Annual Cost) divided by Annual Cost) times 100. Estimate savings as hours saved times your hourly value times 52, and count setup as part of cost.
