Hi can you send a welcome email to newsletter subscribers from Shopify's own email app? I used to use Smartrmail but I have gone over the subscriber cap.
My shop is mainly physical with some online sales so I am trying to see if how to set the rules/automation from the Shopify Email to be able to send these without an additional app.
Unfortunately, the Shopify Email app doesn't offer any automation. You can only send one-off campaigns. The closest you can get without using an additional app is the Customer account welcome notification (in Settings > Notifications).
However, Shopify sends the welcome email to customers who signed up for an account in your store, and not to those who subscribed to your newsletter.
You'll need to use a 3rd party service if you want to send an automated welcome email to your newsletter subscribers.
