Email bounces are a pain. They waste your time, mess up your stats, and can even tank your sender reputation if you’re not careful. If you send cold emails, newsletters, or any kind of outreach, you’ve probably seen your fair share of them.
This guide is for anyone who wants straightforward, practical steps to cut down on bounces—without getting lost in hype or empty promises. We’ll walk through how to actually verify emails using Voilanorbert, what to expect, what’s worth paying attention to, and what you can safely ignore.
Why Bother Verifying Email Addresses?
First off, why verify at all? Simple: email bounces hurt. Here’s what happens if you don’t:
- Wasted effort: You spend time crafting emails that never reach a real person.
- Damaged sender reputation: Too many bounces, and your emails start landing in spam—even for the good addresses.
- Skewed metrics: Your open and click rates look worse than they are.
- Potential blacklisting: In extreme cases, your domain gets flagged and your emails stop getting through everywhere.
If you’re emailing in bulk or reaching out to people you don’t know personally, verifying addresses is table stakes. It’s not magic, but it works.
What Voilanorbert Actually Does (and Doesn’t)
Before we get into the how-to, let’s get real about what Voilanorbert is good for:
- Finds and checks emails: You can use it to both find emails from names/domains, and (more relevant here) verify if an address is likely to work.
- Bulk verification: Upload a big list, and it’ll process them all.
- Gives a confidence rating: You’ll get “valid,” “invalid,” or “catch-all” (more on that below).
But here’s what it won’t do:
- Guarantee 100% deliverability: No tool can promise that. Some domains hide behind catch-alls, and some addresses just stop working overnight.
- Fix your content: If your emails look spammy, they’ll still go to spam—even if the address is real.
Think of Voilanorbert as a solid filter, not a silver bullet.
Step 1: Get Your Email List Ready
Don’t just throw your whole CRM export at a verifier. A little prep saves a lot of money (and headaches):
- Clean obvious junk first: Remove addresses like
test@,info@,no-reply@, or anything that looks fake. - Deduplicate: No point paying to verify the same address twice.
- Format as CSV: Voilanorbert prefers CSV files. First column should be the email, nothing fancy.
Pro tip: If you use LinkedIn scraping tools, expect a lot of dirty data. Spend 5 minutes cleaning it up—your wallet will thank you.
Step 2: Set Up Your Voilanorbert Account
If you’re new to Voilanorbert:
- Sign up for a free trial if you’re just testing (they usually offer a small batch of free verifications).
- Paid plans are based on credits—one verification = one credit. Don’t buy more than you need at first.
Once you’re logged in, head to the “Email Verifier” section.
Step 3: Upload and Start Verifying
Here’s where the magic (well, the automation) happens.
- Upload your CSV: Follow the prompts to upload your cleaned list.
- Map the columns: Usually straightforward if you followed step 1.
- Hit “Start” and wait: For smaller lists, it’s quick. Bigger uploads can take a few minutes.
You’ll get results in three buckets:
- Valid: Safe to send. As close to a sure thing as you’ll get.
- Invalid: Dead, misspelled, or non-existent. Remove these.
- Catch-all: The domain accepts all emails, but you can’t be sure if the address exists. These are the trickiest.
What to do with “Catch-all” addresses?
Honestly, it’s a judgment call. For cold outreach, you might risk it (but send slowly). For important campaigns, skip them—they’re more likely to bounce.
Step 4: Download and Segment Your Results
Export your results and break them down:
- Send only to “Valid” addresses: This is non-negotiable if you care about bounce rates.
- Flag or remove “Invalid”: Don’t waste a single send here.
- Decide on “Catch-all”: If you send, maybe do it in small batches and monitor bounces.
Pro tip: Keep your cleaned list separate from your raw list. You’ll want to re-verify occasionally, especially if you’re emailing the same list months later.
Step 5: Import into Your Email Platform (the Right Way)
Don’t just drag-and-drop your new list into your email platform. Here’s what can go wrong:
- Triggers: Some platforms send welcome emails or add people to sequences right away. Double-check defaults.
- List hygiene: Tag or label your lists so you know what’s verified, what’s not, and what’s “maybe.”
If your platform supports it, segment by verification status. It’ll save you a lot of pain later.
What Actually Lowers Your Bounce Rate (and What Doesn’t)
What Works
- Regular verification: Especially for old lists or scraped data.
- Manual review: Even the best tools miss weird typos or oddball cases.
- Removing catch-alls if you’re risk-averse: Yes, it means a smaller list. But it’s safer.
What’s Overhyped
- “AI-powered” verification: It’s mostly a fancy way of saying “we check with the mail server.” Don’t pay extra for buzzwords.
- One-time cleaning: If you keep emailing the same list, repeat the process every few months. Emails go stale fast.
- Third-party deliverability promises: No one can guarantee inbox placement. Only that the address is (probably) real.
The Limits of Email Verification (Don’t Ignore These)
No matter how good a tool is, you can’t avoid all bounces. Here’s why:
- Some domains use “catch-all” to hide invalid addresses.
- People leave jobs, abandon inboxes, or switch roles.
- Server errors happen—sometimes you’ll get a bounce anyway.
Aim for progress, not perfection. If your bounce rate is under 2%, you’re in good shape. If it’s higher, keep cleaning and double-checking your sources.
Common Gotchas and How to Avoid Them
- Forgetting to clean before uploading: You’ll pay to verify trash addresses.
- Blindly trusting any tool’s results: Always spot-check. Mistakes happen.
- Not re-verifying over time: Even a “valid” list will decay.
- Assuming verification fixes spam issues: Bad content still gets filtered.
Wrapping Up: Keep It Simple and Iterate
Email verification isn’t glamorous, but it’s one of those boring tasks that pays off fast. Use tools like Voilanorbert as a helper, not a crutch. Clean your list, verify, double-check the results, and don’t overthink the process. Start small, see what works for you, and update your workflow as you go.
Don’t obsess over a perfect list—just focus on steady improvements, and your bounce rates will drop.
