Then, you'll want to decide on the messages you want to send, and the intervals at which you want to send them. First write the copy and create templates using your email service—you could even use plain-text messages to get started. Then work on your schedule. Perhaps you'll want to send one email immediately after a new user is added to your list—just connect your spreadsheet to an email app, and have that message sent directly. The others you'll want to delay, perhaps sending new messages three and seven days after they first signed up.

And of course the password. Keep your email account safe and remember that the length of a password determines its security strength as the time required to crack longer passwords increases exponentially. Therefore, your password should consist of at least 8 characters and contain both capital and lower case lettering, as well as numbers and special characters (e.g., "!", "&", "-".). We recommend you change your password from time to time in order to increase the security. Do not choose a password that is easy to guess, e.g. personal data such as: your initials, your date of birth, or the name of a family member or a pet.
