How to Add Forms in Emails to Increase Responses

Let’s be honest, getting your recipients to click a link and fill out a form on a separate page is a big ask. Drop-off is high. Attention spans are short. And traditional email forms — which require redirection — just aren’t cutting it anymore.

What if you could let users fill out and submit forms right inside the email?

No new tabs. No waiting. Just seamless interaction. That’s the promise of embedded email forms.

In this guide, we’ll break down everything you need to know about adding forms in emails — what works, what doesn’t, and how to do it in the simplest way.

How to add forms in emails

Adding forms in emails traditionally involves writing custom HTML code and stitching together complex interactivity using JavaScript. But there's a much simpler — and more effective — solution: Mailmodo.

Instead of wrangling with code, Mailmodo lets you create and embed fully functional, interactive forms directly inside your emails with just a few clicks.

It offers two core types of forms, depending on your use case:

1. Simple forms for simple interactions

Best for: Surveys, referrals, signups

Simple forms are ideal for basic data collection. Think of them like quick lead capture forms or single-question NPS surveys.

How to set up a simple form:

Step 1: Open your email template in Mailmodo editor.

Step 2: Choose the ‘Form’ tab from the left menu bar and drag the Simple Form block into your layout.

Step 3: Customize the form by adding your desired fields or questions and defining the response type, options, etc. You can also add multiple steps to the form.

Once this is done, you can test your form and send it to your recipients.

2. Advanced forms for logic-based interactions

Best for: Quizzes, calculators, product recommendations, registrations

Advanced Forms are powerful, interactive, and highly customizable. You can use them to guide users through multi-step journeys based on their responses.

How to set up an advanced form:

Step 1: Open the email template in Mailmodo that you want to add the form to.

Step 2: Navigate to the Forms section and drag and drop the Advanced form block to the template.
