From their README


A Workflow for Alfred.

Quickly select recipients from your Mac's Contacts database and send them to your email client of choice. Also works with Groups/Distribution Lists.


You can install MailTo either from GitHub releases.

Note: Versions 2.2 and later are only compatible with Alfred 3. If you're using Alfred 2, please install version v2.1.4.


Note: The first time you run MailTo, you will probably be asked to grant access to your Contacts. Obviously enough, if you refuse access, MailTo won't work.

Use the @ keyword in Alfred to access MailTo and search your Mac's Address Book.

Recipients will be suggested from matching contacts and groups in the accounts configured in your Contacts app (see the help file for supported account types).

Hit to autocomplete the recipient list from the selected result, or or ⌘+NUM to add the address to the recipient list and start composing a mail.

You can add multiple recipients by adding a comma between them.

Use mailto to view/change settings.

See the online help for more information.

Supported email clients

MailTo should work with any email client, as it uses the standard mailto: URI scheme to call them.

See the online help for a full list of supported and unsupported clients.
