2026-10-15threads_untrashchangeddescription
before
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.

Bring one thread, or one message of it, back out of the trash. An Outlook mailbox and a mailbox whose provider is imap put a draft back in its drafts, the owner's own mail in sent mail and the rest in the inbox - a Gmail one with every label it carried, each message keeping its id, any other imap one each under a new id the answer names.
2026-10-15threads_trashchangeddescription
before
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 message takes a new id, which the answer names.

A Gmail mailbox whose provider is imap keeps every label but the inbox on it and each message its id; in any other mailbox whose provider is imap each moved message takes a new id, which the answer names.

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.
after · 80% of words in common
Take one thread out of the inbox: a Gmail mailbox, whatever its provider, takes its inbox label off, and an Outlook one moves it into its archive folder. It stays in the mailbox and in search. Any other 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.
2026-10-15threads_modifychangeddescription

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 beside its categories and SPAM, and no other id; a mailbox whose provider is imap takes only UNREAD, STARRED, SPAM and its folders' labels, one folder a call: adding a folder's label moves the inbox messages into it and removing it moves its messages back to the inbox, each message moved taking a new id, which the answer names.

Tools (30)

`drafts_create`	Compose a message in a connected mailbox and keep it there as a draft.
`drafts_delete`destructive	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.
`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_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_send`destructive	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 again: the answer says whether that send went or may have gone.
`drafts_update`destructive	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 previousVersionId.
`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_delete`destructive	Delete one label, by its id from labels_list. No message is deleted: in a Gmail mailbox whose provider is google 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, a Gmail one included, deletes only a folder holding no mail and no folder.
`labels_list`read-only	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_update`destructive	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.
`mailboxes_list`read-only	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_attachments_get`read-only	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 credential.
`messages_forward`destructive	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 already spent sends nothing again: the answer says whether that send went or may have gone.
`messages_get`read-only	Read one message in a connected mailbox, with its headers and its body.
`messages_list`read-only	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`read-only	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 Multi Mail's tools.
`messages_reply`destructive	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 says whether that send went or may have gone.
`messages_send`destructive	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.
`settings_filters_create`destructive	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`destructive	Delete one rule by its id. Mail it already filed stays where it is.
`settings_filters_list`read-only	List the rules a connected mailbox files incoming mail by.
`settings_get_vacation`read-only	Read whether a connected mailbox answers mail automatically, what it says, and any schedule or restriction it carries.
`settings_send_as_get`read-only	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_send_as_patch`destructive	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_update_vacation`destructive	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.
`threads_archive`	Take one thread out of the inbox: a Gmail mailbox, whatever its provider, takes its inbox label off, and an Outlook one moves it into its archive folder. It stays in the mailbox and in search. Any other 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_get`read-only	Read every message of one thread in a connected mailbox, oldest first.
`threads_modify`destructive	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 beside its categories and SPAM, and no other id; a Gmail mailbox whose provider is imap takes only UNREAD, STARRED, SPAM and its own labels, several a call, as Gmail does, each message keeping its id; any other mailbox whose provider is imap takes only UNREAD, STARRED, SPAM and its folders' labels, one folder a call: adding a folder's label moves the inbox messages into it and removing it moves its messages back to the inbox, each message moved taking a new id, which the answer names.
`threads_trash`destructive	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. A Gmail mailbox whose provider is imap keeps every label but the inbox on it and each message its id; in any other mailbox whose provider is imap each moved message takes a new id, which the answer names.
`threads_untrash`	Bring one thread, or one message of it, back out of the trash. An Outlook mailbox and a mailbox whose provider is imap put a draft back in its drafts, the owner's own mail in sent mail and the rest in the inbox - a Gmail one with every label it carried, each message keeping its id, any other imap one each under a new id the answer names.
