Hi, Newsletter premium plan offers a feature to integrate with outside email provider.
I want to know that if I upgrade to Premium plan and integrate with an outside email service, will I need to pay for both Newsletter and outside service?
The external mailing services we refer are integrated to deliver the emails you create with Newsletter. All them offers the SMTP if you want to try them without or addons (but the bounce management and the more performant delivering via API won’t be available).
Yes, they are paid services. If you can deliver emails from your hosting, you don’t need to pay an external service.
