When do I need this?

Before you send a newsletter or offer: find the addresses that do not exist, have typos (gmial.com) or are throw-away, so your mails do not bounce or land in spam.

Good to know

  • We never send any e-mail to the addresses; we only check that they look right and the domain can receive mail.

Words explained

bounce
An e-mail that comes back because the address does not exist.
Excel
A spreadsheet program (tables with rows and columns). Google Sheets and LibreOffice open the same files.
CSV
A very simple table file. Excel and Google Sheets open it.
domain
Your website name, e.g. mybakery.com. It is also the part of an e-mail address after the @.
