Blacklist and reputation repair, in the order that works.

Usually, yes. The order of operations matters enormously and most people make it worse before they make it better. Typically it means stopping all outbound on the affected domain, running placement and blocklist testing to establish where you actually stand, increasing warmup activity, giving it a genuine recovery window, then applying for delisting where required. Meanwhile new outbound moves to separate, properly built infrastructure so the business is not waiting on the repair.

Weeks rather than days, and the honest range is wide because it depends on which lists you are on, how long the behavior ran, and whether sending stopped promptly. Anyone promising same-week recovery on a live sending domain is describing a different service.

Not on the affected domain, and this is the instruction people most want to negotiate. Continuing to send while listed is the most common reason a recoverable situation becomes permanent. New outbound moves to separate infrastructure instead, which keeps the business running without feeding the problem.

Sometimes, and we will say so when it is genuinely the cheaper answer. But it is not a clean escape: a brand new domain has no reputation at all and needs four to six weeks of warmup before it carries volume. Abandoning a domain also abandons whatever good history it had.

Almost always one of three things: a ramp that climbed faster than the receiving domains would tolerate, unverified data producing hard bounces at scale, or a spam trap hit. The repair is only half the work. If the cause is not fixed the new infrastructure follows the old infrastructure.

That is a different and faster conversation. See emergency rescue, which is about getting you sending again this week on separate infrastructure while the repair runs in parallel.
