Apps need to email people: confirm a sign-up, send a receipt, reset a password. JustDeploy sends those from your own address, so the people you email see hello@yourdomain.com rather than something borrowed.
Add your domain
Before anything can be sent, you have to prove the domain is yours. This is the one part your AI cannot do for you, because it happens at the company you bought the domain from.
Open Email in the console, click Add domain, and enter the domain you own. You get three records to publish. Copy each one into your domain provider, where they may be called DNS records or a DNS zone.
JustDeploy checks for the records every few minutes for up to 3 days. Most domains verify within minutes, but some take several hours. If it still has not verified after 3 days, use Try again to restart the check.
JustDeploy sends through Amazon SES. Keep the three DKIM records shown in the console: they sign your mail, even if the provider name matches an older email setup.
Let your app send
Once the row says Verified, your app can send. There is no compose window in the console: sending happens from inside your app, at the moment it has something to say.
Want your app to send? On the Email page, click Copy to grab a short guide (MAIL.md), then paste it into your coding AI. The copied text already tells it what to do, so you don’t type anything. It adds sending to your app for you.
One thing worth knowing, because it shapes what you can ask for: each message goes to one person. Sending to fifty people is fifty messages, not one message with fifty names on it. That keeps a bad address from taking down the other forty-nine.
HTML messages include an open-tracking image, with no per-message off option. Image blocking and preloading make open counts approximate. Delivered means the receiving server accepted the mail, not that it reached the inbox.
What it costs
$0.50 per thousand messages. It comes out of the same credit as your app and your files, so there is no separate email bill, and the $4 of free monthly credit covers around 8,000 messages if you spend it all here.
Keeping your sending healthy
Two things decide whether your email reaches inboxes at all: how many of your messages bounce, and how many people mark them as spam. Both are counted against you by every mail provider in the world, and a bad record is slow to repair.
So we watch those numbers and stop sending if they get too high. It stops for the whole organization, not just one domain, and you will get an email telling you why. Write to support@justdeploy.ai and we will look into it with you.
The best way to avoid this is to send only to people who asked to hear from you, and never buy or reuse an old list. A list bought or left sitting for a year is the usual cause. While you are still building, send to addresses you own.
