If you’re sending a drip campaign, you can use Postmark broadcast messages. It is basically like marketing emails where you have to add an unsubscribe link somewhere on the email. So basically, I’m implying that using some type of marketing email service would be best for announcing new features.

Postmark is also doing a webinar for their broadcast messages if you’re interested: https://twitter.com/postmarkapp/status/1367504956270510081

Hope this helped! :blush:
