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.

The reality of email forms

When we talk about email forms, we mean forms that recipients can fill out directly within the email body. While this sounds ideal, most email clients block key HTML elements needed for true interactivity, such as:

• tags

• Text fields, radio buttons, and dropdowns

• Embedded scripts

• JavaScript-based logic

A few clients, like certain versions of Apple Mail, support fully functional forms, but relying on them will break the experience for most users.

Because of these limitations, truly embedded forms rarely work across all inboxes. To get reliable responses, marketers often need to use strategies that mimic forms or redirect users to a web-based form while keeping the experience smooth and engaging.

How to add forms in emails

The one true way to add forms directly in emails is through the AMP framework.

AMP (Accelerated Mobile Pages) for email allows interactive elements inside the email itself, such as text fields, radio buttons, dropdowns, and submit actions. Recipients can complete actions without leaving their inbox, providing a near-native form experience.

Supported by:

• Gmail Web & Android

• Yahoo Mail (partial)

Not supported by:

• Apple Mail

• Outlook

• Many corporate email systems

AMP forms are useful if your audience primarily uses supported clients and you have the development resources to implement and maintain them. They provide an engaging, interactive experience but require careful planning to avoid broken experiences for unsupported clients.

Mailmodo simplifies the process of adding forms to emails with its drag-and-drop editor. It allows you to place a form directly into your template and customize fields, questions, response types, and even multiple steps. You can also set a success message or redirect after submission and test the form before sending it to your audience.

While AMP forms provide the only fully interactive experience directly inside emails, not all email clients support them. Fortunately, there are other strategies that offer reliable workarounds to collect responses effectively.

Alternative ways to add forms in emails

The main reason to include a form in an email is to collect responses. If AMP isn’t suitable, consider these alternatives:

1. Use CTA buttons that lead to a web form

One of the simplest and most reliable solutions to collect form responses is to use a clear, visually prominent CTA button that directs recipients to a fully functional web form.

When a recipient clicks the button, it opens the web form in a new browser window or tab. The form can be prefilled with parameters from the email (such as the recipient’s name or email address) to reduce friction and improve data accuracy.

This approach works across all email clients and devices, avoids the technical limitations of embedded forms, and allows marketers to track clicks and conversions effectively using analytics or CRM integrations

2. Use images that look like a form

You can create the illusion of an embedded form by using images designed to resemble form fields or interactive elements. Each section of the image can be hyperlinked to the corresponding response page or form.

Examples

• A five-star rating image where each star links to a different URL

• A dropdown mockup that directs to a landing page

• A text-field visual paired with a button that opens the real form

This approach combines visual familiarity with universal compatibility, ensuring that the email looks interactive while still working perfectly in all clients.

3. Use reply-to surveys

Reply-to surveys ask recipients to respond by simply replying to the email with a short code or message. This is particularly effective for mobile users who can reply instantly without navigating to another page.

This method is simple, frictionless, and highly effective for gathering quick insights, especially when you need fast feedback or confirmations.

The best ways to increase email form responses

Reducing friction and making forms quick and easy to complete can greatly increase response rates. Keep these best practices in mind:

• Minimize friction: Cut down unnecessary clicks and steps wherever possible.
  Ask one question: Emails with a single question often see much higher response rates.

• Personalize the request: Use the recipient’s name and reference previous interactions to make the email feel relevant.

• Put the key question above the fold: Make sure the main action is visible without scrolling.

• Add urgency or a reason: Encourage responses with clear motivation, for example, your feedback shapes our next release, we’re picking beta testers—reply if interested.

• Use contrasting button colors: Strong visual contrast can improve click-through and form completions.

• Follow up: Many recipients respond after the second email, so a timely follow-up can capture additional responses.
