How to send email from an app you built with AI

Short answer: Add an email provider to Croft as a connector — SendGrid, Postmark, Mailgun, Resend, and more — then ask your assistant to send email through it. The key stays with Croft; your app never holds it.

Sending email is one of the most common things a small app needs to do: a booking confirmation, a “your request was approved” note, a weekly summary. You just don’t want the email service’s API key sitting inside an app your AI generated.

How to do it

1. Add an email connector. In your croft, add a connector for your email provider and paste its key — or ask your assistant, “connect our SendGrid account.” Croft holds the key, encrypted.
2. Ask your app to send. “When a booking is confirmed, email the customer.” Your assistant calls the email API through Croft’s connector broker — no SDK, no stored key.
3. That’s it. The key is attached on the way out, and the broker only ever calls the provider’s own domain.

Bonus: send on a schedule

Combine it with an automation and your app can email on its own — a daily digest, a Monday report, a reminder the day before something’s due. Ask for a schedule and Croft runs it on time, every time.
