How to setup emails in your Makerkit SaaS application | Next.js Supabase Lite SaaS Kit

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=587
EMAIL_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 Supabase. These have to be setup from within the Supabase Dashboard. You can reuse the same SMTP settings.

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.

InBucket will run automatically when starting the local Supabase environment.

InBucket will now be running at localhost:54324. 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.
