Práce s AMP HTML e‑maily

O AMP

AMP (Accelerated Mobile Pages) je open‑source framework od Google vytvořený z HTML, CSS a JavaScriptu. Umožňuje vytvářet lehké e‑maily s rychlejším načítáním. AMP poskytuje mnoho komponent, jako jsou karusely, formuláře, obrázky atd. Kromě rychlosti umožňuje AMP e‑mailům zobrazovat plně interaktivní e‑maily přímo v e‑mailovém klientovi, kde mohou uživatelé přímo interagovat, například vyplnit formulář nebo odpovědět na průzkum, aniž by opustili klienta.

Práce s AMP HTML e‑maily

Aspose.Email poskytuje AmpMessage který představuje AMP e‑mail. Aspose.Email poskytuje mnoho tříd pro přidání komponent do AMP e‑mailů, jako jsou AmpImage, AmpCarousel, AmpAccordion, AmpForm, atd. Úplný seznam tříd najdete na Aspose.Email.Amp stránka. Následující úryvek kódu demonstruje vytvoření, uložení a aktualizaci AMP e‑mailů pomocí Aspose.Email API.
