The Foundation: Infrastructure That Delivers

Before diving into strategies, let's address the elephant in the room: deliverability. The best cold email in the world is worthless if it never reaches the inbox.

Infrastructure Reality Check

Studies show that 78% of cold emails sent via shared infrastructure end up in spam folders. MailsBuddy's dedicated infrastructure ensures your cold emails reach decision-makers' inboxes, not their junk folders.

Essential Setup Requirements:

  • Dedicated IP addresses with clean reputation
  • Custom domain authentication (SPF, DKIM, DMARC)
  • Subdomain strategy to protect main domain reputation
  • Gradual volume ramping to build sender reputation
  • Real-time deliverability monitoring

The 15 Proven Cold Email Strategies

1
Hyper-Personalization at Scale

Go beyond {FirstName}. Research prospects' recent achievements, company news, or social media activity. Mention specific details that show you've done your homework.

2
The Problem-Agitate-Solution Framework

Identify a specific problem your prospect faces, agitate the pain point with consequences, then present your solution as the bridge to success.

3
Social Proof Integration

Include specific results from similar companies or competitors. Mention recognizable client names (with permission) to build instant credibility.

4
The Breakup Email Technique

Send a "final" email in your sequence suggesting you'll stop reaching out. This often generates the highest response rates due to urgency psychology.

5
Video Personalization

Record short, personalized video messages for high-value prospects. Tools like Loom make this scalable while maintaining personal touch.

6
Trigger-Based Outreach

Reach out when prospects experience specific triggers: funding rounds, new hires, product launches, or industry awards.
