Approximate read time: 9 minutes
Imagine this: A visitor fills out a form on your website, and seconds later, they get a friendly email in their inbox.
It could be a thank you note, a reminder, or helpful guide. And it's all sent automatically while you focus on other tasks. Sounds pretty nice, right?
Setting up email autoresponders in WordPress is an easy way to do it.
In this step-by-step guide, we'll show you how to create custom autoresponders to save hours of work and delight website visitors.
Let's get started.
Upgrade your WordPress site with powerful, flexible forms.
Autoresponders are convenient, but they're also incredibly powerful.
For example, they can improve communication with subscribers by sending a friendly welcome email or improving sales by delivering an upsell email. But that's just the start. Here are a few of the benefits:
So, let's show you how to get an autoresponder email in WordPress in a few easy steps.
From Idea to Reality in Minutes. Build Powerful Forms, Dashboards, Apps and More.
Formidable Forms makes advanced site building simple. Launch forms, directories, dashboards, and custom WordPress apps faster than ever before.
The easiest way to set up an email autoresponder in WordPress is by using Formidable Forms, the most advanced WordPress form builder.
With its Form Action Automation, setting up an autoresponder and customizing it to your liking only takes a few steps. So, use the button below to grab a Formidable paid plan (autoresponders are included in the Elite plan) and get started.
Once you have it, then itโs a few easy steps:
For our example, we have a business called Good Air, Good Life, where customers can buy the best air filters for their houses.
We want to keep our customers coming back to us for business. And we thought one of the best ways to do that is by setting up an autoresponder that sends an email reminding customers to replace their air filters.
Let's dive in.

First, let's get Formidable Forms installed and activated.
Open your WordPress dashboard and go to Plugins โ Add New. Next, search for Formidable and click the Install and Activate buttons.

This installs the free online form builder, which is needed for the Pro version.
So, after that's activated, go to Formidable โ Global Settings page and click the Connect an Account button.

This will open a page that takes you to your Formidable Forms account, where it connects Formidable Pro and WordPress. Once finished, it'll return you to the WordPress dashboard and show your active license type.

Once it's active, we need to activate the Form Action Automation add-on.
To do this, go to Formidable โ Add-ons, find the Form Action Automation, and click the toggle to activate it.

Now that the primary tools are activated, let's create a form.
Now we need an order form for the customer's initial purchase.
To start the form, go to Formidable โ Forms and click the Add New button.

Next, you will have three options:
Since we're creating an order form, we'll use the Order/Billing Form Template to get us started. Then, we can adjust a few things to make it work for what we need.

Next, it will open the drag and drop form builder, which makes it easy to create any type of form in a few clicks. You can drag and drop the form fields or simply click them to add them.

While our order form has most of the fields we need, we must change a few things.
For example, customers can choose between two types of filters and how frequently they want the filter delivered โ once or recurring. They can also choose how often to deliver it and how many they want.
And that means we'll need a total field to do advanced calculations. Formidable Forms Number field can handle this (and more).
So, after some adjustments, our form looks like this:

While it's out of the scope of this article (you can check out our guide on creating a custom calculator for more information on how to do this), here's a quick overview:
([336] == 1) ? (1 * [329]) : ([336] == 2) ? (2 * [329]) : ([336] == 3) ? (3 * [329]) : ([336] == 4) ? (4 * [329]) : ([336] == 5) ? (5 * [329]) : (5 * [329])
This isn't necessary for every order form. But we wanted to show how much Formidable can help your business or site.
So here's what our form looks like on a page:

Now that it's set up (and the form uses PayPal for the order form payments), we can set up the autoresponder.
Now, itโs time to set up our autoresponder settings.
We want to remind people that changing their air filters every 3 months is a good idea if they don't choose the Auto-delivery option.
First, weโll go to Settings and the Actions & Notifications tab and click the Send Email button to create an email.

Next, weโll name the action (customers donโt see this). Then, we'll set the Trigger this action when field to Successful Payment so it doesn't send to incomplete orders.
Then, we'll customize the To section. We want it sent to the userโs provided email address, so weโll click in the To field and select the three dots to the right.

Thereโs a list of the fields you used in our form. So, weโll choose the Email field.
Then, weโll customize our email template with the Subject and Message fields to remind our customers.

But we want this sent only to certain customers, and we'll use conditional logic again to help us do this.
We can click the Add Conditional Logic button, then set up our parameters for when it shows:

We didn't label the field where the customer chooses the frequency, so it appears blank before the equals. This automation we'll set up will only run for the target customer.
Now, all thatโs left to do is set up our automation features. To do so, scroll down and select Setup Automation.
Here, weโll customize our automation to Ignore the trigger action setting above (which would send immediately) and instead send the notification 90 days after the creation date.

That way, once the customer's payment goes through, the automation automatically sends their reminder email for 90 days.
So, the last thing we need to do is click Update to save our changes and display our form!
To show our form, weโll head to our post or page where customers will land to complete the order.
Then, weโll add a WordPress block and search Formidable to add the Formidable Forms WordPress block.

Next, weโll choose our form from the dropdown menu, and thatโs it! When we update our page, the order form will be live and ready!
We only need to change the autoresponder settings to update the automated email messaging or the time period it's set for. Otherwise, it's set-it-and-forget-it!
The example above is only one way an autoresponder can help your website.
