I setup 9 emails (with 3 domains) two months ago on SmartLead and have not sent any emails. At that time, I bought domains from Google and host them on Google workspace. Two questions (a) Should I get rid of them and buy new domains from Porkbun and host email on Outlook or should I still keep these domains? (b) Smartlead gives me a 'Warmup enabled' feature. Should I just turn it on even though I am not ready to send emails yet? Will it take 2 weeks to 'warmup' or are they already warmed up? Thanks!
