Subject: Quick question about your Q3 growth targets

Hi Sarah,

I noticed your team recently expanded into the enterprise segment — congrats on the move.

We helped The City Recruiter generate 71 qualified leads in their first week using a similar approach.

Would it make sense to share how we did it over a quick 15-min call?

Best,
Scott

FAQs

Frequently Asked Questions

What is your definition of a lead?

We define a lead as a prospect who matches your Ideal Customer Profile (ICP) and has expressed positive interest in starting a conversation or booking a meeting.

Are you GDPR compliant?

Yes, we are fully GDPR compliant. We only process data on the basis of Legitimate Interest and ensure all prospect data is handled securely and transparently.

What is a warm up process?

Warm-up is the process of gradually increasing the volume of emails sent from a new domain. This builds a positive reputation with ISPs to ensure your emails land in the primary inbox, not spam.

How do we receive the leads?

Leads are delivered in real-time. You can receive them via direct email notifications, a shared Google Sheet, or through a direct integration with your CRM.

Where do you get the data from?

We aggregate data from premium B2B databases, public registries, and LinkedIn. Every contact is verified in real-time before outreach to ensure valid email addresses.

Do I need LinkedIn Sales Navigator?

While not strictly mandatory, we highly recommend Sales Navigator. It allows for much deeper filtering and targeting, which significantly improves campaign relevance and results.

When can I expect results?

Most campaigns launch within 5 days. While results vary by industry, clients typically see their first qualified leads start trickling in during the second or third week of active outreach.

How long should I use your services?

We recommend a minimum engagement of 3 months. The first month is often about testing and data gathering, while months 2 and 3 are where optimization and scaling occur.

Do you offer campaign reviews?

Yes. We provide monthly performance reports and strategy calls to review metrics, discuss lead quality, and refine our approach for the upcoming month.

Can I change my campaign?

Absolutely. We operate with an agile mindset. If you want to pivot to a new vertical or change your offer, we can adjust the targeting and messaging scripts accordingly.

Do you access our LinkedIn account?

For LinkedIn outreach campaigns, we use secure, cloud-based access that mimics human behavior to keep your account safe while we manage connections and messaging.

Can I pause my campaign?

Yes, we understand business needs fluctuate. You can pause your campaign and billing with a 30-day notice period to allow us to wrap up current conversations.

What are your current campaign results?

On average, our clients see a 3-5% positive reply rate on cold email and a 15-20% connection acceptance rate on LinkedIn.
