Optimizing Cold Email Campaigns in 2025

In the fast-evolving world of cold outreach, navigating the complexities of email infrastructure and deliverability is crucial for success. Frank Sondors, the visionary behind Salesforge and Mailforge, offers invaluable insights into the challenges and opportunities that agencies and sales teams face today. Drawing from years of experience and deep technical expertise, Frank shares practical advice on optimizing cold email campaigns, leveraging AI, and adapting to shifting industry trends.

Understanding the Landscape: Why New Generation Tools Matter

The cold email space is crowded, with many legacy tools still dominating the market. However, these older platforms often treat deliverability issues as purely engineering problems, leaving sales teams and agencies to tackle the fallout on their own. Frank highlights that most companies lack dedicated deliverability experts, and IT teams typically prioritize product development over sales infrastructure.

"Back in the days, you could be blasting a bunch of emails from your primary domains. These days, you can't do that anymore." – Frank Sondors

This increasing complexity has created a demand for innovative, next-generation software solutions like Salesforge and Mailforge. These platforms not only provide advanced technical infrastructure but also emphasize customer support and collaboration, setting them apart from competitors who often distance themselves from their users.

Salesforge: Combining AI and Human Expertise for Cold Outreach

Salesforge is a cold email tool designed to empower users with AI-driven personalization and seamless sequence management. Unlike other tools, Salesforge integrates human sales expertise with AI Agents to optimize campaign performance and deliverability.

  • AI Email Personalization: Salesforge uses AI to tailor messages based on recipients' websites and LinkedIn profiles, increasing engagement rates.
  • Cold Email Sequence Management: Users can easily design and run multi-step outreach campaigns with built-in A/B testing.
  • Email Warm-Up: Automated warm-up features improve sender reputation and inbox placement.
  • Primebox™: A unified inbox view consolidates replies across all mailboxes and sequences for efficient management.
  • Automatic Dynamic IPs and ESP Matching: These features help maintain deliverability and reduce the risk of being flagged as spam.

Frank emphasizes that Salesforge is not just about software - it’s about building trust and offering direct access to the founding team, which is rare in this space. This approach creates a partnership where customers don’t just buy a tool; they “rent” the expertise and support of a dedicated team.

Mailforge: Simplifying Email Infrastructure for Deliverability

Mailforge addresses another critical piece of the cold outreach puzzle: the email sending infrastructure. As email providers like Gmail and Outlook tighten their filtering policies, Mailforge offers a robust SMTP infrastructure that agencies and businesses can plug into quickly and easily.

  • Quick Setup: Mailforge allows users to establish sending infrastructure in about five minutes, saving hours of technical setup.
  • Scalable Infrastructure: It supports high-volume sending with dynamic IPs and tools to manage spam and bounce rates.
  • Expert Support: Unlike large providers, Mailforge offers direct access to knowledgeable engineers who understand cold email deliverability challenges.

Frank notes that Google’s recent announcements about removing app passwords and mandating 2FA will make infrastructure management more complex, further increasing the need for specialized tools like Mailforge.

Key Trends and Patterns in Email Deliverability

One of the critical insights Frank shares is the pattern of account disconnections as an early warning sign of potential blocking. Repeated disconnections often correlate with high spam rates, high bounce rates, poor targeting, or over-sending.

"If your account gets disconnected once, reconnected, then disconnected again, and then reconnected twice - boom, the third time it’s usually blocked." – Frank Sondors

To mitigate these risks, Frank recommends sending emails slowly - aiming for 35 to 50 emails per day - and warming up accounts properly. This cautious approach helps maintain sender reputation and inbox placement.

Top Tips for Successful Lead Generation in Today’s Market

Predicting the future of cold outreach is challenging, but Frank offers three actionable tips for agencies and sales teams aiming to hit their targets in the current environment:

  1. Master the Basics of Copywriting: Ensure your email copy is clear, personalized, and doesn’t trigger spam filters. Test your messages by sharing them with colleagues or friends to identify potential issues.
  2. Network with Other Agencies: Regularly connect with peers - even competitors - to share insights, bounce ideas, and stay updated on industry trends. Frank schedules weekly “networking meetings” with other agencies to collaborate and learn.
  3. Run Rapid, Large-Scale Tests: Don’t rely on a single campaign or a small sample size. Instead, run multiple campaigns targeting different segments, offers, and personalization strategies. Analyze what works and double down on successful approaches.

Frank also highlights the importance of adopting a multichannel outreach strategy. Combining cold email with LinkedIn, cold calling, or other channels significantly improves conversion rates and helps reach prospects wherever they are most responsive.

Collaboration Over Competition: Building a Thriving Ecosystem

Both Salesforge and Mailforge embrace a collaborative mindset. Frank encourages agencies to partner with complementary service providers to offer comprehensive solutions for clients. Whether it’s cold email, LinkedIn outreach, or cold calling, working together creates more value and drives better results.

"You should work with others. It doesn't matter whether you compete or not. If you generate more pipeline for your customer, they will come to you." – Frank Sondors

This consultative approach positions agencies as strategic coordinators who orchestrate multi-channel campaigns, ultimately delivering superior outcomes for their clients.

Final Thoughts: The Future of Cold Outreach

Cold outreach is evolving rapidly, with increasing challenges around deliverability and infrastructure. Tools like Salesforge and Mailforge are designed to help agencies and businesses navigate this complexity with advanced technology, AI-driven personalization, and dedicated support.
