How to setup emails in your Makerkit SaaS application
Sending emails is a critical part of your SaaS application. Makerkit uses emails to send invites to your users only, but it's likely you'll want to send other emails to your users.
To set up emails in your Makerkit application, you should add the following environment variables to your project, using a secure environment:
EMAIL_HOST=EMAIL_PORT=587EMAIL_USER=EMAIL_PASSWORD=EMAIL_SENDER='MakerKit Team <info@makerkit.dev>'Makerkit will use these values to send emails on your behalf using the node library nodemailer.
NB: this does not refer to emails sent by Firebase.
Where do I get these values?
These values are normally provided by your service provider.
Which services are supported?
Any service that supports SMTP should work. We recommend using Resend.
How do I test emails locally?
Makerkit uses InBucket - a platform to testing emails.
InBucket saves time during development since we can test our emails without setting up a real SMTP service - and works locally and offline.
To run the InBucket platform, we need Docker running on our machine.
To start the InBucket service, run the following command:
npm run inbucket:startInBucket will now be running at localhost:9000. When we send an email using the sendEmail function in the kit, we can visualize it using the InBucket UI.
InBucket is used by default during development. Instead, for production usage, you will need to set up a real SMTP service.
Ethereal
In previous versions Makerkit used Ethereal. If you are running an older version, please refer to the below.
Makerkit used Ethereal to allow you testing your emails without using a real email account. To use Ethereal, you should add the following environment variables to your project, using a secure environment:
ETHEREAL_EMAIL=ETHEREAL_PASSWORD=If not set, Makerkit will automatically create an account for you on-the-fly and print the credentials in the console. You can then use these credentials to log in to Ethereal and see your emails.
