What to look for in an outbound agency in Belgium?‍

Choosing the right outbound agency can be the difference between a full pipeline and wasted budget.
With so many options out there, it's important to focus on agencies that understand your target market, personalize at scale, and deliver measurable results.

Clear ICP & List Building Process
Cold Email Framework That Converts
Domain Safety and Deliverability
Protecting your sender reputation is critical. The right agency will set up SPF, DKIM, and DMARC, warm up your domains, and follow sending limits to keep you out of spam folders.
Personalization at Scale
Great cold emails feel human. Look for an agency that uses smart data, tools, or AI to personalize each message in a way that actually resonates with the reader.
Multichannel Outreach Options
Top agencies don’t rely on just one channel. If needed, they can blend cold email with LinkedIn, calls, or even retargeting to increase your chances of getting noticed.
Transparent Reporting and Feedback
You deserve to know what’s working. Great agencies share real performance metrics, explain what they’re testing, and constantly iterate to improve campaign results.
Frequently Asked Questions about Cold outreach agencies
What does a cold outreach agency actually do?

A cold outreach agency helps B2B companies generate qualified leads by running outbound email campaigns. They handle everything from building your ideal customer profile, sourcing leads, writing personalized cold emails, and booking meetings directly for your team. This lets your sales reps focus on closing, while the agency fills your pipeline consistently with high-intent prospects.

How can a cold outreach agency help grow my business?

A cold outreach agency drives growth by getting your product or service in front of the right people at scale. Instead of spending hours manually prospecting, you get a team that uses tools like Clay or Apollo to find leads based on real buying signals. They create and manage cold email sequences that generate replies, drive conversions, and increase your monthly sales pipeline with minimal lift from your team.

How much does it cost to hire a cold outreach agency?

Prices usually range from $2,000 to $10,000 per month. It depends on how many leads you want, how complex your targeting is, and whether you need guaranteed meetings. Some agencies offer packages with a fixed number of leads or booked calls. Others charge based on performance. The key is to measure ROI. One good deal often covers the entire cost.

How long does it take to see results from cold outreach?

Most campaigns take around 2 to 3 weeks to start showing signs of traction. That includes email deliverability setup, warming up domains, testing subject lines, and refining your messaging. By the end of the first month, you should start seeing consistent replies and meetings. Cold outreach isn’t instant, but when it’s done right, it scales fast and keeps your pipeline healthy.

What should I look for when choosing a cold outreach agency?

Look for an agency that understands your industry, uses modern prospecting tools, and can show you proof of results. Ask if they personalize emails, test different messaging angles, and track performance transparently. Agencies that use Clay, Instantly, or Smartlead tend to be more advanced. A good agency doesn’t just send emails, they act like a strategic partner that helps you convert outreach into revenue.
