Update campaign
Change the name, subject or sender of a draft campaign.
MCP tool mailjet_write → update_campaign
write
Sets the campaign name, the subject line and the From name and address of a draft. A scheduled or sent campaign cannot be edited and returns an error. The sender address must be one you may use in Mailjet. The design is not touched. The change reaches no one and is undone by calling the tool again, so it does not wait for your OK.
