What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

• click2mail_list_return_addresses

  The addresses of one type saved on the account (return addresses, billing, business reply, courtesy reply, EDDM mailer addresses) with their ids; use an id as `return_address_id` when creating a job. GET /molpro/account/addresses.

• click2mail_get_product_options

  The mail products and valid option combinations (document class, layout, production time, envelope, color, paper, print option, mail class) for the account. Use the exact strings from this reply in click2mail_create_job and click2mail_estimate_cost. GET /molpro/productOptions.

• click2mail_estimate_cost

  Estimate the cost of a mailing from its print options and quantity without creating anything (nothing is charged). Use the exact option strings from click2mail_get_product_options. GET /molpro/costEstimate.

• click2mail_list_documents

  List the documents uploaded to the account (id, name, class, pages), most recent first. Use a document id when creating a job. GET /molpro/documents.

• click2mail_get_address_list

  Status of an uploaded address list: processing state (3 = CASS-standardized and ready for a job), name and counts. GET /molpro/addressLists/{id}.

• click2mail_get_address_list_info

  Details of an address list: its addresses with the standardization result of each. Click2Mail returns 10 addresses by default: page with limit and offset. GET /molpro/addressLists/info.

• click2mail_check_addresses

  Validate and standardize up to 100 US postal addresses (USPS/CASS correction) before mailing. Read-only: nothing is saved or sent. POST /molpro/addressCorrection.

• click2mail_create_address_list

  WRITE: upload a recipient address list (up to 500 addresses) to the account. The list is standardized (CASS) by Click2Mail; poll click2mail_get_address_list until status 3, then use its id in click2mail_create_job. Creates data only; nothing is mailed or charged. POST /molpro/add

• click2mail_upload_document_from_url

  WRITE: have Click2Mail fetch a PDF (or other supported file) from a public http(s) URL and store it as a document on the account. Returns the document id for click2mail_create_job. Creates data only; nothing is mailed or charged. POST /molpro/documents/url.

• click2mail_list_projects

  List the account's projects (jobs are grouped by project; jobs without one are grouped by month, e.g. "March 2022"), most recently updated first. Use a project name with click2mail_list_project_jobs. GET /molpro/projects.

• click2mail_list_project_jobs

  List the mailing jobs of one project (id, status, description). This is how to see the account's jobs: pick a project from click2mail_list_projects. GET /molpro/projects/jobs.

• click2mail_list_jobs_by_app_signature

  Full details of a job: print options, document, address list, dates, cost and payment. GET /molpro/jobs/info/{id}.

• click2mail_get_job_tracking

  USPS tracking for a submitted job: per mail piece barcode, address, status, date and location. Tracking updates once a day, so one call per day is enough; nothing is tracked on staging. GET /molpro/jobs/{id}/tracking.

• click2mail_get_job_cost

  The exact cost of a created job (postage, printing, fees) for a payment type. Read it before click2mail_submit_job. GET /molpro/jobs/{id}/cost.

• click2mail_create_job

  WRITE: create a mailing job from an uploaded document and an address list. The job stays a draft (status Editing): nothing is printed, mailed or charged until click2mail_submit_job. Use the exact option strings from click2mail_get_product_options. Returns the job id. POST /molpro

• click2mail_request_job_proof

  WRITE: ask Click2Mail to render a proof (preview PDF) of a draft job. Free; nothing is mailed or charged. The reply names the proof; it takes a moment to render. POST /molpro/jobs/{id}/proof.

• click2mail_submit_job

  WRITE, SPENDS MONEY, NOT REVERSIBLE: submit a draft job for printing and USPS mailing. This charges postage and printing to the account (User Credit = prepaid balance, or Invoice) and the physical mail is sent to every recipient. Before calling: read click2mail_get_job_cost and c

• click2mail_cancel_job

  WRITE: cancel a SUBMITTED job. The vendor documents this only for jobs paid by invoice and only before processing for mailing has started; otherwise it fails. The mailing is stopped for good, so get the user's explicit go-ahead first; `confirm` must be true. To remove a draft use

• click2mail_delete_job

  WRITE: delete a job that has not been submitted (status Editing or PendingProofAcceptence). Submitted jobs cannot be deleted; use click2mail_cancel_job. POST /molpro/jobs/{id}/delete.
