How the Email Validation Tool works

2. Click Import File to upload a CSV or TXT file, or add individual contacts manually.
3. The tool checks your addresses and sorts them into categories, including Valid, Invalid, Spamtrap, Catch-All and more.
4. Once validation is complete, download your cleaned list of valid email addresses, ready for your next campaign.
Good to know
The Email Validation Tool has its own credit balance and purchasing system, separate from your TurboSMTP account.
You can validate email addresses as long as you have sufficient validation credits.
How to read your validation results
Valid: Email addresses with a bounce risk below 2%.
Invalid: Non-existent addresses or addresses with permanent errors. These should be removed from your list.
Catch-All: Addresses on domains configured to accept emails even when the recipient’s mailbox doesn’t exist.
Spamtrap: Addresses used to detect spam. Sending to them can damage your sender reputation.
Abuse: Addresses associated with recipients who frequently report emails as spam.
Do not mail: Addresses, including temporary ones, that are best excluded from your campaigns.
Unknown: Addresses that couldn’t be validated due to inactive servers or spam filters.
How often should I validate my email lists?
We recommend validating your email lists every 8–12 months and regularly monitoring contact engagement. This helps you keep your lists up to date and reduce the risk of sending to invalid addresses.

FAQ
An email validation tool is a software that helps verify the accuracy and validity of email addresses in your contact list. It checks if the emails are properly formatted, exist, and are not associated with spam traps or invalid domains.
A spam trap is an email address set up to catch spammers. If you send emails to a spam trap, it can damage your sender reputation and lead to your emails being flagged as spam or blacklisted.
While both terms are often used interchangeably, an email validator typically refers to a tool that checks the format and validity of an email address, whereas an email verifier might also include checks against known databases and real-time verification.
