Warm before you switch
Start warm-up weeks ahead, so the new domain has history on switch day.
For domain migration
Move to a new domain without losing the inbox.
Short answerWhen a company moves to a new email domain or provider, the new domain starts with no reputation. RoxInbox sets up authentication, warms the new mailboxes before the switch, and tests placement at each step so customers keep receiving your email.
The job
Switch domains or email providers without customers and prospects losing your email to spam.
