Where Do I Find Sent Emails?

  • Delivery services like Mailgun, SparkPost and Sendgrid also provide this information.

Selecting Recipients
  • Options to send mail to any user, or limit to users with first and last names on their profile.

  • Users need permission to list users, to view user list or change options. Minimum permission can be changed with an option or filter.

Sending Mail from Other Addresses
  • Uses Mailgun plugin settings for Administrators, if the plugin is activated, using Override "From" Details and Mailgun API.

  • Uses SparkPost plugin settings for Administrator name and email address, if plugin is activated and Overrides for name and email are set.

  • Option for administrators to use Sendgrid API.

  • Replace Quick Mail Sender is an experimental plugin that changes the Quick Mail sender’s name and email address.

  • Programmers can replace their credentials by adding a filter to replace_quick_mail_sender. This only works if you are not using another mail plugin’s credentials.

  • Requires permission to use your email address.

  • Requires permission to save email addresses. Saved addresses are cleared if permission option is changed.

  • Up to 12 manually entered recipients are saved in HTML Storage.

  • Additional recipients can be either CC or BCC but not both.

  • Multiple files can be uploaded from up to 6 folders (directories).

  • “Uploads are disabled” on some mobile devices.

Some devices cannot upload files. According to Modernizr :

iOS < 6 and some android version don’t support uploads.

File uploads are disabled for ancient IOS 5 devices. Please add a support message if uploads are disabled on your phone or tablet, so I can remove the upload button if your device is detected.

Address Validation
  • Address validation is an option to check recipient domain on manually entered addresses.

  • International (non-ASCII) domains must be converted to punycode with idn_to_ascii.

    Unfortunately, idn_to_ascii is not available on all systems.

  • “Cannot verify international domains because idn_to_ascii function not found”

    This is displayed when Quick Mail cannot verify domains containing non-ASCII characters.

  • checkdnsrr is used to check a domain for an MX record.

    An MX record tells senders how to send mail to the domain.

    This is not always accurate. Turn verification off if Quick Mail rejects a valid address.

Mail Errors
  • Quick Mail sends email with wp_mail.

    wp_mail error messages are displayed, if there is a problem.

  • You must provide at least one recipient email address.

    wp_mail rejected an address. Seen when Quick Mail verification is off.

Incompatible Plugins

Stop Emails displays To send emails, disable the plugin.

If you are using an email delivery service, you can ignore this message.
