Here's why you shouldn't forget about the warmup:
1️⃣ First, warming up your domain is a way to avoid spam filters.
Cold emails are unsolicited, and there's a higher risk of them being marked as spam or landing in the spam folder.
A warmed-up domain and inbox have a more established sending history, which allows internet service providers (ISPs) to see that you are an actual human rather than just spam.
2️⃣ Another thing warmup does is build your sender reputation.
ISPs evaluate your sender reputation based on how much email activity you have. Sudden spikes in email volume from a new or inactive domain can be seen as suspicious.
So, if you buy new domains and try to send thousands of emails the next day, it will immediately show that you are a spammer.
That's why it's important to grow your domains gradually.
