Does switching domains reset reputation?

Partially true. A new domain starts with zero reputation, not zero problems. Mailbox providers like Gmail and Outlook watch new domains closely, and if you carry the same bad habits over, you'll burn the new domain just as fast.

Think of it this way: switching domains is like moving to a new neighborhood. The neighbors don't know you yet, but if you show up playing loud music at 2am, you'll have the same reputation problem within a week. The domain isn't the issue. Your sending behavior is.

So before you make the switch, here's what actually needs to change:

• Clean your list first. Remove addresses that haven't opened in 6-12 months, hard bounces, and anything flagged as a spam trap. If your old domain got burned by list quality, the same list will burn the new one. A stale list is the most common culprit, and it follows you everywhere.
• Fix your complaint rate. If subscribers are hitting "spam" instead of "unsubscribe," that's a consent problem, not a domain problem. Audit your signup flow. Make sure people genuinely opted in and know what they signed up for. A complaint rate above 0.1% will damage a new domain fast.
• Check your bounce handling. Are you removing hard bounces immediately? Are you monitoring soft bounces? Sending to dead addresses tells mailbox providers you're not maintaining your list, and that signal moves with you to any domain.
• Set up authentication on the new domain before you send a single email. SPF, DKIM, and DMARC need to be in place from day one. A fresh domain with broken or missing authentication looks suspicious immediately. You can check your SPF and generate your DMARC record for free before you even publish the new domain.
• Warm up the new domain slowly. Start with your most engaged subscribers (recent openers, clickers) and ramp up volume over 4-6 weeks. Don't migrate your full list on day one. Warmup takes time, and skipping it is how new domains end up in spam before they've even had a chance.

One more thing worth knowing: some reputation associations can follow you even after switching. If your brand name is well known as a spam source, or if you're on a shared IP that has its own baggage, a new domain alone won't fully reset how filters see you. Fixing the underlying sending practices is the only real reset.
