Cold email continues to be one of the most effective ways for businesses to generate B2B leads and open conversations with potential clients. But in 2025, success with cold email is no longer about simply hitting “send.” Deliverability, scalability, personalization, and infrastructure all play a huge role in determining whether your email lands in the inbox or the spam folder.
