Domain warm-up
Also called Email warm-up.
Domain warm-up is sending a small, slowly growing number of emails from a new domain, so inboxes learn to trust it.
A new domain has no sending history. If it sends hundreds of emails on day one, inboxes may put them in spam. So you start with a few real emails a day and raise the number each week, while people open and reply.
Send cold email from a second domain, not your main one, so a problem never hurts your normal email. Set up SPF, DKIM and DMARC first. Warm up for 2 to 4 weeks, then spread your 100 cold emails a day over several inboxes. Warm up the domain step by step.
