How can MxToolbox or HetrixTools aid recovery?

Your domain landed on a blocklist and now emails aren't reaching inboxes. You need to know where you're blocked, what to do about it, and how to prove you've fixed it. That's where MXToolbox and HetrixTools come in.

What MXToolbox does for you. It's the all-in-one diagnostics tool. Run a blocklist check and you'll see if your domain or IP sits on Spamhaus, Barracuda, or any other major blocklist. You'll also see what those blocklists say about why you're listed (spam complaints, bounce rate, pattern abuse, etc.). Beyond blocklists, MXToolbox validates your DNS records, tests SPF and DKIM and DMARC implementation, and analyzes email headers. Use it to verify that your authentication fixes actually worked before you request delisting.

What HetrixTools adds. HetrixTools is the monitoring specialist. It watches your IP and domain continuously and alerts you the moment a new blocklist listing appears. You don't have to remember to check manually. If you're trying to recover from being listed, HetrixTools gives you the peace of mind that you'll catch any relisting immediately. It also maintains historical data so you can track your delisting progress over time.

The recovery sequence. Step 1. Use MXToolbox to check your current blocklist status. Step 2. If you're listed, read the specific reason and fix the root cause (usually list quality, bounce rate, or authentication). Step 3. Update your authentication records (SPF, DKIM, DMARC) and clean your list. Step 4. Use MXToolbox again to verify your records are correct and request delisting through the blocklist's process. Step 5. Set up HetrixTools monitoring so you never get caught surprised again. (Of course, delisting can take days to weeks.)

Start with bounce recovery and SPF validation. These are the most common blocklist triggers. If you're overwhelmed by the delisting process, Review My Emails SOS can walk you through your specific situation.
