Definition of the “Hard Bounced emails”

In general, the addresses you find in Hard Bounced emails are emails addresses to which the message has not arrived and never arrive in the inbox for the following reasons:

  • The email address is incorrect
  • Email address does not exist
  • The address is considered suspicious by ISPs because used for creating Spamtraps (all the email addresses with an alias as: abuse@, sales@, admin@, info@ are classed as Hard Bounce.)

These email addresses (abuse@, sales@, admin@, info@) are not personal and they are published on the website so they are easily copied without the consent of the end user. This is why Email providers create Spam traps using these common aliases, and this is also the reason why we block them. Internet Service Provides discard as spam all the email campaigns sent to these email addresses and they can blacklist the sender and their IP addresses.

Why are invalid email addresses (hard bounced emails) bad for your campaign?

When an email provider (as Gmail, Hotmail, Yahoo or others) detects a high number of invalid or incorrect emails, they block all the messages coming from the same sender. In fact they suppose that the sender has collected his mailing list illegally and therefore the messages are classed as spam.

Verification system of email addresses

Our system performs a double checking of your emails in order to verify their validity.

The first verification is done when you import your contacts, with a tool that allows us to identify 80% of invalid addresses.

The second verification consists in a system of logs and feedbacks after sending your first email campaign. Every invalid address is recorded in our system as Hard Bounced email and isolated. The addresses are therefore automatically excluded from any future sending of your email campaigns. Even if you delete your mailing list, or your contacts, we keep track of Hard bounced emails in order to avoid users to reimport them and send another email campaign on the same invalid addresses. The email address stays in your mailing list but you
