Is an outsourced SDR worth it for a small agency?

It can be, for speed. You won’t own anything when it ends.

I never paid for it. I always thought it was overpriced. I built a signal agent instead that watches news feeds, target accounts, job boards, and decision-makers’ social posts.

Do AI SDR tools work?

They do exactly what you tell them, which is the good news and the bad news.

Can I combine options?

Yes. A built system with one part-time person making calls from it covers most of what a small agency needs.

Hire an SDR, use an AI SDR, or build your own outbound system?

How do the options compare?

Option	Cost	Time to start	What it handles	What it can’t do	Who maintains it
Hire an SDR	About $80,000 a year in on-target earnings, plus tools	Weeks to hire, then a ramp	Calls, emails, follow-up	Scale past one person’s day	You manage them
Cold email agency or outsourced SDR	$3,000 to $15,000 a month	Fast, often with a 3-to-6-month minimum	Lists, sending, booking	Run your other channels	The agency, while you pay
AI SDR tool	$12,000 to $45,000 a year and up	Days	High-volume sending	Judgment on what it finds	The vendor
Do it yourself with Apollo and Instantly	About $100 a month in entry plans, plus your time	As long as it takes you	Whatever you set up	Run while you’re selling	You
A built system (DoBetter)	Fixed fee, scoped after a $1,500 discovery	Weeks, depending on scope	List, enrichment, signals, sending, replies into your CRM	Take the meetings for you	Built for you, tuned with you

Sources: SDR pay from Bridge Group’s 2025 SDR report. Agency fees from IntentSignal’s 2026 pricing guide. AI SDR pricing from 11x (from $3,750 a month, billed annually) and Vendr’s data on Artisan (entry tier $12,000 a year). Tool prices from each vendor.

I’ve run most of this table myself. I built an AI SDR team when I first built my CRM, and I’ve paid for Apollo, Instantly, FullEnrich, and Apify.

When is hiring an SDR the better choice?

Hiring an SDR is the better choice when there’s enough work to fill 40 hours a week and someone who’ll actually train them. I was an SDR for my first year and a half in B2B insurance, and I’ve hired and worked alongside them since. The honest truth, about them and about me: half the time we didn’t know what we were doing. We were told to set appointments and not to sell the product. Sell time on the calendar. God forbid anybody asked what the product was, at which point we promptly vomited all over them. A good SDR is worth the salary. Getting one to good takes training most small agencies don’t have time to give.

When is a cold email agency the better choice?

A cold email agency is the better choice when email is the only channel you want and you’d rather rent it than build it. I’ve never hired one, and the reason is simple. Cold email is one channel in a go-to-market strategy and one tool in a go-to-market system. The list, the signals, the calls, and the follow-up still have to live somewhere, and when you stop paying the agency, the channel stops with it.

When is an AI SDR tool the better choice?

An AI SDR is the better choice when you already know exactly who you sell to and someone will keep its instructions current. I built my own AI SDR team: one agent to scout companies, one to find signals, one to qualify, one to write, and one to check the work.

The first failure was mine. It pulled in tens of thousands of what I thought were ideal leads, but the industry codes I filtered on couldn’t tell a real buyer from a lookalike. Once I fixed the list, the team was phenomenal at following instructions: qualifying, finding signals, writing, and checking the writing.

The bad news is they were really good at it. When I tweaked the copywriter’s instructions, I forgot to tweak the quality checker’s. It failed everything. The human was the bottleneck.

When is doing it yourself the better choice?

Doing it yourself is the better choice when the list is short. If you’ve got 20 prospects, ChatGPT and a sending tool like Instantly will do it. If you’ve got 2,000, the research has to run without you, and that’s where DIY stops.

When is a built system the better choice?

A built system is the better choice when you plan to run outbound for years and want to own it. The research, the voice rules, and the reply handling get built once around how you sell, and every campaign after that gets cheaper. I built one for my own outbound: 15 mailboxes, about 11,000 organizations, with every reply landing in my CRM with a drafted response.
