Email Verification Explained

Since 2012 Internet Service Providers have worked hard to reduce the ever growing number of SPAM emails sent every day. ISP’s identify email senders as spammers if they email invalid email accounts because it indicates that they might not be real subscribers.

This is a huge problem for email marketers who have legitim email lists with real subscribers. If their contact list is older than 3 months they could be easily mistaken for spammers and their email sending reputation will be permanently damaged. And as a consequence their email sending account will be suspended.

Email marketers must verify their email lists if they haven’t sent an email for at least 3 months in order to keep their contact lists up-to-date and legitimate. No more paying $500 to verify 100,000 subscribers, at HuBuCo you can clean your lists at affordable prices with guaranteed great results.
HuBuCo is committed to delivering the highest quality email verification service with strict data protection policies set in place to protect our customers' data. 

Email Verification Process

During email verification we remove any duplicates from your file, we check email syntaxes, check the email servers DNS, create an SMTP connection with the recipients' server to find out if the email accounts exist. We do this without sending an email to your contacts.
We also detect catch all servers and temporary email addresses, and highlight free and role email accounts.

You can upload your contacts in TXT, CSV or XLSX file and our results are available to download in a standard CSV file. If you would like you can send us files programmatically or you can program our single API into your system to verify email addresses in real time.

We follow strict data protection principles and comply with European GDPR. Should you need more information please contact our support team.
