How do I request removal from Barracuda?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
If you're a B2B sender and your emails keep getting blocked at corporate firewalls, there's a good chance you're on the Barracuda blocklist. Barracuda is used heavily in enterprise environments, so a listing here can quietly kill your B2B outreach even when everything else looks fine.
Before you request removal, check whether you're actually listed. Head to barracudacentral.org, enter your IP address, and look at your reputation score. If you're listed, that page will tell you so. Don't skip this step and go straight to the form.
Once you've confirmed you're listed, you need to understand why before you write anything. Common reasons include high spam complaint rates, sending to invalid addresses, sudden spikes in sending volume, and landing on a spam trap. If you submit a removal request without knowing the cause, you'll either get denied or re-listed within days. Take a look at your bounce logs and complaint data first.
When you're ready to submit, use the removal request form at barracudacentral.org. Here's what to actually write:
- Your IP address (the one that's listed, not your domain)
- What you send (newsletters, transactional, sales outreach, etc.) and to whom
- What went wrong (be honest, even if it's embarrassing, they've seen it all)
- What you've already fixed (cleaned your list, removed unengaged contacts, added authentication, tightened opt-in, reduced sending volume, whatever applies)
- Contact email so they can follow up if needed
Still the phrase "fixed the problem" means nothing without specifics. If you cleaned your list, say how many contacts you removed and why. If you added SPF or DKIM, mention that. Barracuda reviews these manually, and a vague form submission won't move things forward.
Barracuda typically responds within a few days. They may ask follow-up questions, and if they do, answer them fully. A short, dismissive reply is a fast track to denial.
After removal, keep a close eye on your sending metrics for the next few weeks. Getting re-listed quickly tells Barracuda the underlying problem wasn't actually solved, and that makes a second removal much harder. Think of removal as a checkpoint, not the finish line.
If you're not sure what caused the listing or want a second set of eyes before you write the request, our SOS hotline is free and we actually help (no sales pitch, promise).
