Hello! My name is Norbert!
I can verify your email lists
Only $.003/email up to 500k and $.001/email above that. $2 min.
How many emails to verify?
I will only ask you:
They trust me with email verification
Norbert wants your email to reach real people.
...and doesn’t want to see you get blacklisted.
When emails are sent to invalid email addresses, they bounce. The more you bounce, the lower your sender score will drop. You'll be trapped by spam filters and eventually blacklisted. Norbert makes sure every email you send, reaches a real person. This will increase your deliverability, open rate and revenue.

We’ve been using VoilaNorbert for a while now at Salesflare and

The best thing about Norbert is how accurate it is.
Return rates are well above what I was used to from other tools and the emails don’t bounce either.
I imagine this is due to the fact that they also have a strong email verification engine running in the back which
is also available as a separate service.

I use the Norbert Chrome Extension for finding email addresses when doing link building.
Being able to do it all within Chrome without leaving the site is super helpful.
It's one of the quickest and one of the most accurate at uncovering email addresses.

Accuracy and precision: I trust Norbert 100%.
I have been doing cold mail outreaching for my company's in-house products for a while now.
Norbert always helps me out when I'm blocked and eases my work effectively than any other apps I have ever used.

Voila Norbert is great for getting the email addresses you need.
It’s also easy to use: you just type in the name, last name, domain and get the email address in return.
We’re using it for lead generation, retrieving contact information of marketing leaders, as well as advertising decision makers.

Have more questions about Norbert?
What kind of sorcery is this?
Hello! I'm the majordome behind Voila Norbert where I identify emails and maximize lead generation for my clients. During that process, I have to verify emails one by one. This tool above is coming handy if you only want to verify your email lists in bulk! A question? I'm always around.
Hmm.. so you verify emails, Norbert?
I already verify thousands of emails everyday as part of my incredible email identification algorithm. Now you can tap into this specific part of the algorithm as well!
What will you charge to verify my emails?
I'll charge you only $.003/email up to 500k and $.001/email above that. $2 minimum charge. The more you verify, the less you pay!
Does a "deliverable" email address have absolutely no chance of bouncing?
I can't guarantee 100%, error-free results. Email verification is very complex and depends on each specific email server that your clients are using. I spent the last couple of years trying to figure things out and I think it's working pretty well, but I can't say that it's foolproof.
You have a API I can use?
Our Verify API is fully documented and built to integrate into your work flow or site.
Do I have to sign a contract? Create an account?
No and no. You don't have to create an account and even less enter in some kind of agreement with me. Just submit your list of emails, I'll process them straight away and get back with an answer.
What kind of file format is accepted?
I currently accept CSV files. You can easily export as .CSV from Google Sheets or Excel. Too hard? just paste your email column in the copy/paste section!
What exactly does it mean when an email address is marked "risky"?
Certain email providers are restricting email verification on their servers. I found some ways to minimize that and provide as much information about an email I can, but that still happen from time to time. "Risky" means that I think it's deliverable, but there is a chance of bounce.
What do you check for when verifying emails?
I verify if the connection to the mail server owning this email address can be established properly, if the email still exists and if it doesn't appear to be a catch-all. After that, I also have some secret sauce ingredients to ensure proper accuracy!
