Increase the quality of your e-mail addresses
Correct typos live during form entry or afterwards in the mailing list to lower your error rate.
Newly gained e-mail addresses can be invalid and incorrect. The main reasons are typos in top level domains (e.g. web.dw, gmail.co, hotmeil.com), unused domains, domains that are no longer valid, throw-away addresses, spam traps for identifying spam mails, Bot addresses which are automatically generated via script or addresses or Robinson list addresses.
The Address Check actively lowers your error rate: It recognizes errors and many other problems and already eliminates these during their entry into the online form if necessary. In some cases typos can be particularly painful. For example in the travel sector or online shops where travel documents or invoices are sent via e-mail as attachments.
