Challenges of Verifying Emails at wolterkoops.nl

Verifying emails at wolterkoops.nl can be challenging due to several reasons:

• No Bounce Messages: wolterkoops.nl may not always return a bounce message even if you send test messages to an invalid email address, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails

Failing to verify emails at wolterkoops.nl can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list may contain invalid or non-existent addresses, leading to a high bounce rate, which can damage your sending reputation and result in a lower delivery rate, open rate, and click rate.
