What it can do

Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.

• rapidmail_list_recipientlists

  List the recipient lists (newsletter audiences) of the rapidmail account with id, name, description, whether unsubscribed recipients are blacklisted, and which is the default. Use the ids for recipients and mailing filters. GET /recipientlists.

• rapidmail_get_recipientlist

  One recipient list by id. GET /recipientlists/{id}.

• rapidmail_get_recipientlist_activity_stats

  Subscription activity of one recipient list between two dates (for example new subscriptions and unsubscriptions). The range may be at most one year, must not start before the list was created and must not lie in the future. GET /recipientlists/{id}/stats/activity.

• rapidmail_list_recipients

  List the recipients (subscribers) of ONE recipient list, optionally filtered by e-mail address, external id or status. recipientlist_id is required. The long text fields (extrabig1-10) are only returned with include_extrabig. GET /recipients.

• rapidmail_get_recipient

  One recipient by id: e-mail, name, status, custom fields and timestamps. GET /recipients/{id}.

• rapidmail_create_recipient

  WRITE: add ONE recipient (subscriber) to a recipient list. By default double opt-in is used: the recipient is created with status 'new' and rapidmail sends ONE confirmation e-mail to that address; they only receive newsletters after confirming. Set double_opt_in=false only if you

• rapidmail_update_recipient

  WRITE: partially update ONE recipient (only the fields you pass change): e-mail, name, custom fields. The status and the recipient list cannot be changed here, and no e-mail is sent. An e-mail address that already exists in the list returns a conflict error. PATCH /recipients/{id

• rapidmail_unsubscribe_recipient

  WRITE: remove ONE recipient from their list. rapidmail only soft-deletes the record (status 'deleted', as if the person had unsubscribed) and the statistics count it as an unsubscription. No goodbye e-mail is sent. Single recipient only. DELETE /recipients/{id}.

• rapidmail_list_mailings

  List newsletters (mailings) with status, subject, sender, send time, recipient count and recipient lists. Filter by status, recipient list, created / updated / sent date. Read only: mailings are never created, sent or scheduled by this server. GET /mailings.

  One mailing by id: status, subject, sender, destinations (recipient lists), send time, size and attachments. GET /mailings/{id}.

• rapidmail_get_mailing_stats

  Statistics of one sent mailing (opens, clicks, bounces, unsubscriptions and similar totals). GET /mailings/{id}/stats.

• rapidmail_list_mailing_activity

  The recipients a mailing went to and what each did (delivered, opened, clicked, bounced). Detailed event information is only available if the respective plugin is enabled in the rapidmail account. GET /mailings/{id}/stats/activity.

• rapidmail_get_mailing_recipient_activity

  Delivery and engagement details of one recipient of one mailing. GET /mailings/{id}/stats/activity/{mailingrecipient_id}.

• rapidmail_list_mailing_folders

  The folders used to organise mailings, with id and name. GET /mailings/folders.

• rapidmail_list_blacklist

  The account's blacklist: e-mail addresses, domains and patterns that never receive mailings, with their type, source and dates. GET /blacklist.

• rapidmail_list_transactional_emails

  Transactional (SMTP) e-mails sent through the rapidmail account: sender, recipient, subject, status (queued, delivered, bounced...), delivery diagnostics and open/click counts. Metadata only, no message bodies. Filter by date, status, project or address. GET /trx/emails.
