Who can send mail?

  • Users must be able to publish a post to send an email. Minimum permission can be changed with a filter.

  • WP-CLI: Only administrators can send mail with the quick-mail WP-CLI command.

Who can send rich text messages?

  • User must have Visual Editor enabled on their profile, to compose messages with the Visual Editor.

  • Anyone can send HTML by pasting it into a message.

Where Do I Find Sent Emails?

  • You should be able to find sent emails in your email account’s Sent Mail folder.

  • 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.

Mail Delivery Services

  • 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.

Sending Mail from Other Addresses

  • Install the Replace Quick Mail Sender plugin, to change the Quick Mail sender’s name and email address.

  • NOTE: Other email plugins can change these settings.


  • 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.

  • 99 recipients for Gmail, others.

  • 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

  • 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.

  • Error: Invalid Role (WP-CLI error)

    You tried sending mail to an unknown WordPress role. Use wp list roles to get role names.

Incompatible Plugins

  • Stop Emails

Stop Emails displays To send emails, disable the plugin.

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