Weekly B2B Sales Roundup – Week of January 3, 2026

Main Story: Cold Email Deliverability Crisis – The Silent Killer of Outbound in Early 2026
Many B2B salespeople, founders, and SaaS teams are struggling with cold email campaigns landing in spam or failing to reach inboxes at all. Strict new rules from Google and Microsoft, combined with over-saturation and poor setups, have made high-volume blasting ineffective, leading to burned domains and plummeting reply rates. This hits hard as teams rely on outbound to fill drying pipelines amid slower inbound and higher ad costs.Why it matters right now: 2025 changes to email authentication (DMARC enforcement) and AI-driven spam filters have tightened, while economic uncertainty pushes more reliance on predictable outbound. Teams sending without proper warmup, rotation, or monitoring see inbox placement drop below 50%.Key takeaways or quick fixes:

  • Prioritize quality over quantity: Limit to 20-50 emails/day per inbox with ongoing warmup.
  • Use decentralized infrastructure (multiple domains, Google Workspace/MS accounts).
  • Monitor deliverability daily and verify lists aggressively.
  • Focus on hyper-personalization and value-driven copy.
  • Diversify with LinkedIn and calls as email becomes harder.
