Email Warmup: Email marketing keeps changing fast. New spam filters, strict rules, and innovative tools make sending emails harder. To land emails in inboxes, warmup is key. This matters most for agencies and brands sending lots of emails.
Why Email Warmup Is Important
Email providers watch for sudden jumps in sending. They check for real replies, opens, or clicks. If an account sends too much, too soon, with little action, emails can land in spam or get blocked. That hurts budgets and stops sales. The email warmup trends 2025 show that sending slowly and acting like a human helps avoid these problems.
