Cold Email for Staffing Agencies

For staffing agencies, outbound is the engine for client acquisition. But most teams are stuck in a loop of manual prospecting, using fragmented tools, and sending from their primary domain—a recipe for inconsistent results and major deliverability risk.

Scaling a pipeline of new client accounts isn't about finding a magic template. It's an infrastructure problem. The agencies winning in 2025 are building scalable, multi-channel outbound systems, not just sending more emails.

The competition for new client accounts is fierce. Hiring managers are inundated with pitches from other agencies. Relying on brute force tactics no longer works. Here’s where most agencies get stuck:

1. Inconsistent Pipeline: Your pipeline is feast or famine because manual outreach doesn't scale predictably. When your team is busy filling roles, prospecting stops, and the pipeline dries up.
2. Your Main Domain is a Single Point of Failure: Sending outreach from your primary @myagency.com domain is a massive risk. One spam complaint can get your domain blacklisted, crippling communication with existing clients and candidates.
3. Fragmented Outreach: Your reps use LinkedIn, email, and maybe a CRM, but nothing is coordinated. Follow-ups are missed, prospects get mixed messages, and you have no visibility into what's actually working.
4. Generic Messaging Gets Deleted: Most agency outreach is self-serving, focusing on process instead of client problems. Without a system to test and measure what resonates, you're just guessing.

The top-performing agencies treat outbound like a disciplined, repeatable system. It's less about creative genius and more about operational excellence.

1. Hyper-Targeted Lists: Don't just buy a list of "companies in tech." Build targeted segments based on buying signals: companies that just raised funding, have multiple open roles for a specific position, or recently hired a new department head. Quality over quantity is key.

2. Problem-Centric Messaging: Don't lead with "We're a staffing agency." Lead with their problem. Your messaging should prove you understand their specific hiring challenges.

Example 1: Targeting a Head of Engineering

Subject: Senior DevOps roles

"Hi [Name], saw your team is hiring for three Senior DevOps Engineers. My team specializes in placing SRE/DevOps talent in the fintech space—we recently filled a similar role at [Relevant Company] in under four weeks. Is it worth a brief chat to see if we can accelerate your timeline?"

3. Multi-Channel Follow-up: Relying on email alone is a mistake. A modern sequence involves 5-7 touches across email and LinkedIn over two to three weeks. The goal is to be professionally persistent without being annoying. An email followed by a LinkedIn connection request a day later is a simple but effective pattern.

An outbound strategy is useless if your emails land in spam. Once you try to send more than 50-100 emails a day, you move from a messaging problem to an infrastructure problem.

Sending hundreds of emails from a single Google Workspace account will get you shut down. It wasn't built for that. At scale, you need a dedicated sending infrastructure:

1. Dedicated Sending Domains: Never send from your primary corporate domain. Use variations like [agency]partners.com or [agency]results.com to protect your main brand's reputation.
2. Multiple Warmed-Up Inboxes: Distribute your sending volume across dozens of inboxes (e.g., kurtis@agencypartners.com, k.tryber@agencypartners.com). Each inbox should be properly warmed up over weeks to build a positive sending reputation.
3. Automated Inbox Rotation: A platform should automatically rotate which inbox sends the next email, keeping volume per inbox low and safe.

Recruiting agencies send to personal inboxes (Gmail, Yahoo, Outlook.com) and corporate domains. This mix is highly sensitive to deliverability issues. Using primary domains is a massive risk—once Gmail flags your domain, your entire agency's deliverability suffers. This is why agencies rely on secondary domains + inbox rotation.

Here are a few repeatable plays you can run with the right infrastructure.

1. Net New Account Outreach: Target hiring managers at companies with clear hiring signals. Use a 5-touch sequence over two weeks, blending 3 emails with 2 LinkedIn touches (a connection request and an InMail/message). The goal is to book a discovery call.
2. Market-Specific Campaign: Target a niche, like "Series B fintech companies hiring for sales roles." The copy is highly specific to that market's pain points. This is a 4-touch, email-only sequence designed to establish authority quickly.
3. Reactivation of Old Clients: Target past clients you haven't spoken to in over six months. A simple 3-touch email sequence can uncover new hiring needs and restart conversations. The message is low-pressure: "Checking in, saw you're hiring for X, wanted to see if you had it covered."

You've crossed the threshold when outbound stops being "one rep hacking in a spreadsheet" and becomes a core business process. This happens when you need to manage multiple reps, send from 10+ inboxes, and coordinate multi-channel sequences without anything falling through the cracks.

This is the point where you need an infrastructure-first platform like SuperSend. It’s not another CRM or a lead database. It’s the sending engine that manages your domains, automates inbox warmup and rotation, and executes coordinated sequences over email and LinkedIn.
