mailboxes_list | List the connected mailboxes that answer, each by the name a tool's mailbox input takes, and the tools its provider does not offer. The mail of every mailbox mailboxes_list names is read and written with Multi Mail's tools. |
messages_list | Search one connected mailbox in its own provider's query language, Gmail's or Outlook's. The mail of every mailbox mailboxes_list names is read and written with Multi Mail's tools. |
messages_list_all_mailboxes | Search every mailbox you have connected in one call. The answer names the mailbox each result came from, names any mailbox it could not search, and is merged newest first by when each message arrived, a thread by its newest. The mail of every mailbox mailboxes_list names is read and written with Mul |
threads_get | Read every message of one thread in a connected mailbox, oldest first. |
messages_get | Read one message in a connected mailbox, with its headers and its body. |
drafts_create | Compose a message in a connected mailbox and keep it there as a draft. |
drafts_update | Change a draft in a connected mailbox. A field the call leaves out stays as the draft has it. A mailbox whose provider is imap keeps the edited draft under a new id the answer names, and the old id then reads nothing; an old version its server did not remove stays in Drafts, named as previousVersion |
drafts_reply | Compose a reply to a message as a draft, inside the thread it answers and quoting it below the reply: to whoever wrote it, or with replyAll to everyone on it. Nothing leaves the mailbox until the draft is sent. |
drafts_forward | Compose a forward of a message as a draft, with the files it carries and inside the thread it already sits in. Nothing leaves the mailbox until the draft is sent. |
drafts_delete | Throw away a draft. Nothing already sent is touched. Gmail mailboxes only: an Outlook draft keeps its identifier once sent, so discarding one could delete sent mail. |
messages_send | Compose a new message in a connected mailbox and send it in one call. Call this only when the person asked for this message to go; when they asked to prepare one, draft it instead. A request id already spent sends nothing again: the answer says whether that send went or may have gone. |
drafts_send | Send a draft. It leaves the mailbox and consumes the draft. Only a draft is sent: a message already sent or received is refused, and nothing leaves. Call this only when the person asked for this message to go; when they asked to prepare one, draft it instead. A request id already spent sends nothing |
messages_reply | Reply to a message, inside its own thread and quoting it below the reply: to whoever wrote it, or with replyAll to everyone on it. Call this only when the person asked for this message to go; when they asked to prepare one, draft it instead. A request id already spent sends nothing again: the answer |
messages_forward | Forward one message to the addresses you name, with the files it carries, inside the thread it already sits in. Only the provider's own limit applies to what it carries. Call this only when the person asked for this message to go; when they asked to prepare one, draft it instead. A request id alread |
labels_list | List the labels a connected mailbox holds, by the id each is applied by. A mailbox whose provider is imap holds its folders as labels, nested by /, beside UNREAD, STARRED and SPAM. |
labels_create | Create a label in a connected mailbox and answer the id it is applied by. In a Gmail mailbox, and as a folder in one whose provider is imap, a / nests it under the label before it, made first where missing; in an Outlook mailbox a / is just a character. |
labels_update | Rename a label, recolour it, or both. The id comes from labels_list. An Outlook mailbox's categories are its labels, and Microsoft lets one take only a new colour. A mailbox whose provider is imap renames its folder, which takes no colour, and answers the label's new id. |
labels_delete | Delete one label, by its id from labels_list. No message is deleted: in a Gmail mailbox the label comes off every message; an Outlook mailbox's category leaves its list, and the messages that carried it keep its name. A mailbox whose provider is imap deletes only a folder holding no mail and no fold |
threads_modify | Apply and remove labels on one thread, or one message of it - an Outlook mailbox's categories are its labels. The ids come from labels_list. Adding SPAM junks it, and taking SPAM off brings it back to the inbox. In a Gmail mailbox adding TRASH bins it too; an Outlook mailbox takes UNREAD and STARRED |
threads_archive | Take one thread out of the inbox. It stays in the mailbox and in search. A mailbox whose provider is imap moves its inbox messages into its archive folder, made as Archive where it has none, each under a new id the answer names. |
threads_trash | Move one thread, or one message of it, to the trash - Gmail's bin, an Outlook mailbox's Deleted Items, the trash folder of a mailbox whose provider is imap - where it stays until threads_untrash brings it back or the provider's own retention ends it. In a mailbox whose provider is imap each moved me |
threads_untrash | Bring one thread, or one message of it, back out of the trash. A mailbox whose provider is imap puts a draft back in its drafts, the owner's own mail in sent mail and the rest in the inbox, each under a new id the answer names. |
messages_attachments_get | Read one attachment of a message. The answer is what it says, as plain text; with as original it is the file itself, base64. messages_get and threads_get name a message's attachments and their sizes. Either answer names the address the original is served at whole, to a GET carrying this same credent |
settings_filters_list | List the rules a connected mailbox files incoming mail by. |
settings_filters_create | Create a rule that files incoming mail in a connected mailbox. A rule that carries mail out of the mailbox, or that bins or junks what it matches, is refused, whether or not the provider would take it. An Outlook mailbox's rule files only under labels or out of the inbox (removeLabelIds INBOX). |
settings_filters_delete | Delete one rule by its id. Mail it already filed stays where it is. |
settings_send_as_patch | Replace the signature on the mailbox's own send-as identity. Nothing of the old one is kept, so read it first with settings_send_as_get. An empty signature clears it. Gmail mailboxes only: an Outlook mailbox exposes no signature to write. |
settings_send_as_get | Read the signature on the mailbox's own send-as identity, as HTML. A mailbox with no signature answers without one. Gmail mailboxes only: an Outlook mailbox exposes no signature to read. |
settings_get_vacation | Read whether a connected mailbox answers mail automatically, what it says, and any schedule or restriction it carries. |
settings_update_vacation | Turn the vacation responder on or off. A Gmail mailbox replaces the whole responder, so a schedule or a restriction it already held is not kept; an Outlook mailbox keeps what this call does not name, and holds no subject. |
