Enveloop Email API
Enveloop lets developers design, send, and track email and text messages from Fly applications using a simple API. They can store all message content, images, HTML, and CSS in Enveloop – keeping Fly apps lightweight.
This service is in public beta on Fly.io. A couple of notes:
Enveloop is a production service. For our Fly.io launch, we are in public beta as we tighten up the integration.
During the beta period, you won’t be charged for Enveloop usage.
Create an Enveloop project
Creating an Enveloop project happens via the Fly.io CLI. Once the Fly.io CLI is installed, sign up for a Fly.io account and create your first Fly app. From there, you can add an Enveloop project to your app.
Running the following command in a Fly app context (inside an app directory or specifying -a yourapp) will create a new Enveloop project and Fly Secrets (sandbox & production) on your app.
flyctl ext enveloop create
? Select Organization: moon (moon)
? Choose a name, use the default, or leave blank to generate one:

Pricing and Billing
During the public beta, Enveloop is free to use on Fly.io.
Enveloop starts at $5 per month. With that, we include 1000 messages per month – each message over 1000 is $0.005. As you send more messages, individual messages sent cost less – the breakdown below illustrates. While we only charges for messages (email or text) sent, the $5 minimum helps cover logging, data retention, and support. You can view the official Enveloop Pricing page for additional information.
Here is a breakdown of the per message costs, per month, as your usage on Enveloop scales.
- $0.00500 - 1000-5000 (minimum $5 spend)
- $0.00250 - 5001-50,000
- $0.00170 - 50,001-100,000
- $0.00145 - 100,001-500,000
- $0.00140 - 500,001+
Enveloop usage fees are billed daily and will show up, throughout the month, on your Fly.io invoice.
Enveloop plans include unlimited use of our message builder, templates, analytics, logging, and our webhooks. Also, you can add as many users as you need. These features are accessible via the Enveloop web console.
Additional information about Enveloop capabilities are located in the Enveloop Docs.
