WP Opt-in

Collect e-mail addresses from users with a simple form. Send them an e-mail automagically.

Can I send e-mail to all users who have asked for information through this plugin?

Yes. Simply copy all the e-mail addresses from the 'Bcc friendly format' section on the plugin options page. Paste them into the Bcc field in your favorite e-mail client software.

No e-mails are sent! Why?

Check if PHP is configured to use a working SMTP server, possibly in a file called php.ini.

What does Bcc mean?

Blind carbon copy. A receipient field for e-mail. Using it results in not revealing e-mail addresses between the recipients.

Why do the plugin mess up my theme when including it in the sidebar?

The options might be messed up. Try the default options:

  • Bad e-mail: <p><b>Bad e-mail address.</b></p>
  • Failed to send: <p><b>Failed sending to e-mail address.</b></p>
  • Success: <p><b>Sent requested e-mail.</b></p>
  • Form header: <div id="wpoi_form">Receive information automagically here.
  • Form footer: </div>
  • E-mail field: E-mail:
  • Submit button: Submit

Can spammers use this to get me in trouble?

Subject, sender and contents of the e-mail sent from this plugin is controlled by the plugin and you. There should be no reason for sending someone this information unless they asked for it.

What about security?

The input e-mail address is checked for suspicious characters before it's used.
