How to recover a burned domain?

Your open rates have cratered. Replies have stopped. Emails you know are good are landing in spam everywhere. If that's where you are right now, your domain's reputation is probably burned, and the first question you'll ask is: can I fix this, or do I just start over?

The honest answer is: it depends on how bad the damage is. Let's walk through how to find out, and what to do either way.

Step 1: Figure out how burned it actually is

Before you do anything, get a clear picture of where you stand.

• Check Gmail Postmaster Tools. Look at your domain reputation score. "Low" or "Bad" means you have real work ahead. "Medium" is recoverable faster.
• Check the major blocklists. Spamhaus is the most important. If you're on the Spamhaus DBL (domain blocklist), that's serious. Barracuda and Spamcop matter too, but they're generally easier to get off.
• Check Microsoft SNDS if you send to Outlook or Microsoft 365 users.
• Pull your recent sending data. High bounce rates, high spam complaint rates, and sudden drops in opens are all clues about what caused this.

Our free blocklist checker can show you where your domain is listed right now. Worth doing before you decide on a path.

Step 2: Stop the bleeding immediately

Whatever you were doing that caused the damage needs to stop today. Cold outreach to stale lists, sending without proper SPF and DKIM, emailing people who never opted in, ignoring bounce and complaint signals. None of that continues while you're in recovery mode.

Request delisting from any blocklists you're on. Follow their specific processes (Spamhaus has a removal form, Barracuda has one too). Don't just submit and forget. Actually fix the underlying issue first, then submit, or they'll just relist you.

Step 3: Rebuild with your best senders

Pause all cold campaigns entirely. For now, you only send to people who have actively opted in and recently engaged with your emails. This is the audience that opens, clicks, and doesn't report you as spam. Their positive signals are what rebuilds your reputation with mailbox providers.

Think of it like a warm-up starting from near-zero. Low volume, high engagement, very clean list. You're re-teaching mailbox providers that mail from your domain is wanted.

This process takes weeks to months, not days. A "Medium" Gmail reputation might recover in 4 to 6 weeks of disciplined sending. A "Bad" reputation can take 3 to 6 months, sometimes longer. There's no shortcut. Sending more aggressively during recovery will make things worse, not better.

When to start fresh instead

Sometimes recovery isn't the right call. Consider retiring the domain if:

• You're listed on Spamhaus DBL and the listing was due to sustained abuse (not a one-time mistake). Spamhaus doesn't forget easily.
• Your domain has a long history of high complaint rates. That history follows the domain even after you clean up your practices.
• You've been in recovery for 60 or 90 days and metrics aren't moving. At some point, the time and effort cost more than a fresh start.
• The domain is a cold outreach subdomain anyway. It costs less to spin up a new one than to spend months nursing a damaged one back.

And if you do start fresh, don't just copy your old habits onto a new domain. A new domain doesn't fix a broken process. You'll burn it too, usually faster, because mailbox providers are watching new domains extra carefully. Do the warm-up properly from day one.

The recovery decision in plain terms

Mild damage with a fixable cause and a good opted-in list to work with? Recovery is worth attempting. Severe blocklisting, long-term abuse history, or no engaged audience to rebuild with? Starting fresh is probably the faster path. (And yes, it's frustrating to abandon a domain you've had for years. But the domain doesn't have feelings. Your deliverability does matter.)
