How to choose an outbound agency
An outbound agency runs prospecting for you: building lists, writing and sending outreach, following up and booking meetings with your sales team. A good one can get you meetings faster than hiring and training your own SDRs. A poor fit wastes months, so it pays to compare carefully.
Questions to ask before you sign
- Who is it for? Ask for results with companies like yours, in your industry, deal size and target market. An agency that books meetings for marketing agencies may struggle with enterprise software.
- Which channels? Cold email, LinkedIn, calling or a mix. Multichannel programmes usually reach more people, but cost more.
- Who owns the assets? Check who owns the sending domains, inboxes, lead lists and CRM data if you part ways. Ideally, you do.
- What counts as a qualified meeting? Agree the definition in writing: job titles, company size, need and whether the prospect has to show up.
- How will you see results? Ask for regular reporting on emails sent, replies, positive replies and meetings, not only activity.
- What are the terms? Minimum commitments, notice periods, setup fees and what a guarantee actually promises.
How agencies charge
Most charge a monthly retainer, which buys the team's time and tools. Others charge per meeting or per lead, which lowers your risk but often costs more per meeting and depends heavily on how "qualified" is defined. Some combine a smaller retainer with a performance fee. Retainers for full-service outbound commonly run from a few thousand dollars a month upwards.
Setting expectations
The first few weeks usually go on research, messaging and infrastructure setup, especially for cold email, where new inboxes need warming up. Judge an agency on the quality of meetings over the first two or three months rather than the first fortnight. Browse agencies by service using the links above, or compare the tools they use.
Frequently asked questions
How much does an outbound agency cost?
Full-service outbound agencies commonly charge monthly retainers starting from a few thousand dollars, rising with channels, volume and the number of SDRs. Pay-per-meeting agencies charge for each qualified meeting instead, which usually costs more per meeting but less up front.
Is a retainer or pay per meeting better?
A retainer suits companies that want a long-term partner and control over messaging and targeting. Pay per meeting lowers your risk when testing outbound, but check carefully how a qualified meeting is defined.
How long does it take to see results from an agency?
Expect the first weeks to go on setup: research, messaging and infrastructure. Many agencies start booking meetings within the first month or two, and results usually improve as campaigns are tested and refined.
Should I hire an agency or an in-house SDR?
An agency gets you started faster, with tools, data and experience included, and is easier to stop. An in-house SDR costs more to hire and ramp but builds knowledge inside your company. Many companies start with an agency to prove outbound works, then hire.
Who should own the domains and data?
Ideally you should. Agree in writing that the sending domains, inboxes, lead lists and CRM records belong to you, so you keep them if the engagement ends.
