# Personalize Welcome Emails
> Personalize and send meaningful welcome emails to new users after a couple of hours.
Let's say we want to send a personalized welcome email to users a couple of hours after they've signed up on our app.
**We'll build a workflow that does this in 5 minutes**.

## 1. Create an event-based trigger
In this example, let's assume the frontend of our app connects user sign-ups to our PostgreSQL database. We'll start by setting up our Paragon workflow with an [Event-based trigger](/automate/building-workflows/triggers#event-based) so that our workflow runs when a new user is created in our PostgreSQL database.
[Connect your PostgreSQL database](/automate/resources/integrations-catalog/postgresql#setup-guide) to Paragon and create a new column labeled `signedUp`. We'll use this column to let us know the date and time our user signs-up.
Under **Choose an action**, select **New record created**.
Under **Table**, choose the table you'd like to check for new users.
Under **Order by**, choose the column that **represents the time and date** the user signed up. In this example, we'll select `signedUp`.
## 2. Delay immediately sending the email
We'll use the **Delay** step to wait a certain amount of time before executing the next steps in our workflow.
In this example, we want to delay our welcome email to our new users by 6 hours. Once the workflow reaches this point, it'll wait 6 hours before continuing with the next steps.
**Note:** Delaying a workflow doesn't prevent future executions of your workflow from starting.
Check out your workflow executions in your [Task History](/automate/building-workflows/viewing-task-history#overview).
## 3. Send the user an email
Paragon supports [several integrations](/automate/resources/integrations-catalog#messaging) for messaging – and for this example, we'll use [Sendgrid](/automate/resources/integrations-catalog/sendgrid) to send each user an email. Add a Sendgrid step to your workflow, connect your Sendgrid account, and choose the **Send Email** action.
Under **Recipients**, click the dropdown to bring up the variable menu and choose the user's email address from the [PostgreSQL event-based trigger.](/automate/resources/integrations-catalog/postgresql#event-trigger) In the **Subject** and **Message** fields, you can insert data from previous steps (e.g. your users' name, etc.) by typing `{{` to bring up the variable menu.
## 4. Deploy your workflow
Now that your workflow is all set up, deploy your workflow by clicking the "Deploy" button in the top-right of your screen. Once you do, your workflow's Trigger URL will go live and you can start making requests to it.
Great work! We just built a workflow to send personalized welcome emails to new users a couple of hours after they've signed up!
Of course, this is just a basic example of what you can do with Paragon, and there's much more we could add to this workflow, e.g. issuing a refund, marking the user as canceled in your database, etc. We hope it gives you an idea of how to use Paragon for your own internal workflows!
