I have purchased a domain from namecheap, let’s call it main.com Should I do warm up emails on this main domain, because my website will also be from this main domain. Or should I purchase other domains like “trymain.com” and “usemain.com” and do warmups on that and use those to send email marketing / cold emails? Also, I’m buying these domains from namecheap and I’ll set it up on google for Gmail and then I’ll use instantly for warming up, does that sound like a valid strategy? Would really appreciate a quick convo with someone who’s done all This before! Thanks in advance
