outsourced cold email outreach

Precision

Manual lead vetting is a non-negotiable

We hand-check every prospect against your buyer personas’ features — industry, role, challenges, and buying signals — so your team only meets people who matter.

Qualified meetings, not just replies

We go beyond “any reply” by qualifying for real buying intent, so your team steps into conversations that can move deals forward.

Engagement

Human touch in every message

Our dedicated strategists with industry-focused expertise tailor each template to your personas and study your unique brand voice to ensure every message feels like it came from your team.

Smart response handling

Whether it’s “not now,” “more info,” or even a negative, we process each reply manually to reengage at the right time and uncover hidden opportunities.

Execution

Compliance and deliverability by design

Belkins’ deliverability and tech specialists adhere to the latest GDPR/CAN-SPAM policies and monitor your domain health daily to protect your reputation and land safely in the inbox.

Pipeline acceleration beyond appointments

We always go the extra mile: reengage no-shows, nurture warm leads, support your reps with the context they need to close, and audit your entire marketing and sales strategy.

Cold email campaign launch

Our SDRs roll out your campaign with discipline and precision. They:

Apply your approved messaging sequences, personalized to each buyer segment
Follow a proven follow-up cadence — shorter intervals early on, then gradually longer
Monitor engagement metrics like opens, clicks, and reply types to adjust timing, content, and frequency
Ensure every prospect gets timely, respectful touchpoints without over-messaging

Amplifying email prospecting with intent-based data

We offer cross-channel outreach for even higher conversions. We can boost your performance by:

Gradually sending LinkedIn connection requests and messages for building stronger client relationships
Developing a professional B2B content strategy for your LinkedIn to position your company and its key personas as industry leaders
Incorporating warm calls based on the intent data and engagement to secure appointments scheduled via emails or LinkedIn
Doing warm calling in tandem with offline industry events to schedule face-to-face appointments
Reengaging with your inactive leads via cold calls
