Feature & Specification Comparison
Tools & Capabilities Breakdown
Email Spam Tester Tools (4)
get_test_address
Reserve a single-use address to send a draft email to, for a full check.
Returns the address and the URL its report will appear at. The address
accepts exactly one message and expires after an hour. The email has to be
sent by the person, from the platform or mailbox they really send from:
half the checks read what that platform adds. The report covers 42 checks
(SPF, DKIM, DMARC, reverse DNS, TLS, blocklists, content, links, the
Gmail and Yahoo bulk-sender rules) and a plan of what to fix.
lang is decided now because the message arrives minutes later over SMTP,
which carries no hint of who is waiting for it. What wait_for_report
returns quotes check lines in English whatever it is set to; the person
following report_url sees their own language.
wait_for_report
Wait until the message arrives and has been analysed, then summarise it.
Call it after the email has been sent to the address from
get_test_address. Blocks rather than returning "not ready yet": an agent
told to poll writes a sleep loop and usually gives up before the analysis
finishes. Provider placement keeps filling in for up to 30 minutes after
the report; get_report reads the latest.
get_report
Read a report by its slug without waiting, with provider placement so far.
Works for one-hour tests and for letters in the person's series mailboxes.
