The "Invalid Addresses" function helps you identify email addresses that are technically undeliverable due to obvious errors. This useful cleaning function improves the quality of your subscriber lists and increases the efficiency of your email campaigns.

Key features:

• Automatic detection of technically invalid email addresses
• Identification of typical errors such as missing @ symbols or incomplete domains
• Verification of all or selected subscriber lists
• Flexible handling of identified invalid addresses: Delete or export

The function identifies various types of errors, including:

• Missing structural elements (e.g., no @ symbol)
• Incomplete domain information
• Prohibited special characters in the local part

After verification, you have the option to either delete the invalid addresses directly or export them for manual post-processing. Note that making corrections on your own without the recipient's consent is not recommended for legal reasons.
