Soll ich mit SMTP oder API integrieren?

Wir empfehlen, je nach den Möglichkeiten und Anforderungen Ihrer Anwendung die am besten geeignete Methode zu verwenden.

Below given are few facts for your information on HTTP API integration:

It is faster than SMTP
You can send emails at a much larger scale than SMTP
Saves your server resources as the email generation is taken care by us.

SMTP on the other hand is easy to integrate as you just need to replace your existing SMTP credentials along with SMTP relay host within your application.
