GetResponse's built-in tools cover the basics, but the inbox preview workflow often benefits from a dedicated, browser-only preprocessor before uploading. {ESP_NAME}'s built-in preview shows one rendering — usually their own webmail. Real cross-client testing means simulating Gmail Web, Apple Mail iOS, and Outlook desktop side-by-side before you send.

Why pre-process before uploading to GetResponse

GetResponse's spam-trigger check is rule-based but limited to subject and body word patterns.
