Getting into the inbox requires a level of verification that only we can provide. Our 5 stage approach catches more “bad” addresses than anyone else. Finally, a B2B email verification company you can believe in.

Trailblaze runs layered checks to determine whether a B2B email is deliverable or not — screening each email address as if it were going through customs at an airport. This is how we keep bounce rates lower than any other company, period.
The stages · Gate to gate
No cost is incurred here. Before a single verification mile is spent, your file is cleaned against the records you already own.
Every address is inspected and, where it can be, corrected — so a fixable record is repaired instead of thrown away.
DNS verification and an MX record lookup confirm that the domain is real and that a mail server is standing behind it.
The “Ping.” An SMTP connection is opened to the receiving server to confirm the inbox itself exists — without sending an email.
Advanced classification and filtering separate the addresses that are technically real from the ones that will still hurt you when you send.
We provide B2B email verification at a lower cost along with included tools that you actually will want. Select any item below to view details.

Whether you are sending 200 emails or 200,000, high bounce rates will absolutely ruin your campaign. You will get blocked, spammed, blacklisted, etc.
If your data isn’t “super” clean, you won’t make it in the inbox, let alone be able to stay there. Your sending accounts will be ruined, your email platform will potentially cut you off and your content will be spammed.
Basically, you will have to create more sending accounts, maybe switch platforms, create new content and… spend more money!
Seems like all the other companies claiming “99% accuracy” are good at only one thing: making you spend more money and waste more time.
Here’s what we did to help you understand the difference — and to come up with our Guarantee.
We scraped social media sites and compiled 12,000 unique business records containing email addresses.
After formatting and normalizing the data, we randomized it and split it into 6 individual files of 2,000 records each.
We then took each individual, unique file and verified it with 6 companies, us included.The other five are above, but we’ll leave their names out for this
We took the “Good” — sometimes called “Deliverable” — results only from each company and loaded them into 6 separate email campaigns. Each campaign had fresh and warmed sender accounts and fully tested content.
We pushed all 6 campaigns live, and the results weren’t exactly surprising.

Every company received an identical, randomized 2,000 record file. Where the emails sent figure is lower than the deliverable count, the sending account was suspended or the campaign was stopped part way through — those lists never finished sending.
Only the email account and campaign that used data verified by Trailblaze stayed alive, with perfect domain reputation, copy health and no spam reporting.
3 of the other accounts using the other companies’ verification were completely shut down after only a portion of the list was emailed.
The other 2 that even finished sending were completely dead after about half were sent. Everything went to spam at that point, and those accounts and domains are now only good for the trash can.
If a competitor of ours provides better, safer results than us, we will refund you the verification cost of that list and we can part as friends.
You just need to submit the request and supporting documentation showing the same list (business data) and accompanying results. We won’t make it difficult.
Upload a CSV or XLSX file and get results on up to 500 records without creating an account… Yes, we believe in our results that much.
