Yes, warming up a new domain plays a big role in inbox placement, especially when you're sending emails to promote affiliate offers. If you start sending large volumes of emails from a brand-new domain without any warm-up, email providers may see it as suspicious. This can lead to your emails going to the spam folder or getting blocked completely. Warming up means you start by sending a few emails to trusted contacts, then gradually increase the number over time. This shows email providers that you’re not a spammer and that people are engaging with your messages. When you’re doing affiliate marketing, this process helps build a good sending history. It also improves your chances of landing in the inbox where your offers can actually be seen and clicked. Inbox placement is important for getting results, especially when promoting offers.
