Top 6 Email Marketing Platforms for In-Email Forms and Surveys 

Email marketing remains one of the strongest marketing tools today, especially given a predicted increase in the number of email users worldwide. According to the latest email marketing statistics, “around three-quarters of marketers prefer email as their go-to channel for ROI, where up to 2x improvement can be achieved year over year.”

Traditional methods and surveys force subscribers to click through to landing pages, wait for pages to load, and interact with unfamiliar interfaces. Each of these hurdles introduces friction that costs you responses and quality data.

In-email forms and surveys remove this friction. Subscribers enter information and submit responses right in their inbox, no clicks, no waiting, no context switching. The result? 2-3x higher completion rates and quality data.

In this guide, I'll walk you through the top email marketing platforms that allow you to embed forms and surveys right in emails for maximum response rates.

Quick Summary

Here are the best platforms for in-email forms and surveys:

1. Mailmodo - Best for AI-powered interactive forms and surveys

2. Litmus - Best for testing forms across email clients

3. Typeform - Best for conversational in-email surveys

4. SurveyMonkey - Best for professional survey integration

5. Google Forms - Best free option with email integration

6. Formstack - Best for advanced form logic and workflows

Why In-Email Forms Matter

Forms and surveys sent to landing pages typically see 10-15% completion rates. In-email forms see 25-40% completion rates. That's a 2-3x improvement simply by removing friction.

Traditional Survey Flow: Email → Click → Landing Page Load → Start Survey → Submit → Confirmation (4+ clicks, 30+ seconds)

In-Email Survey Flow: Email → Fill Survey → Submit (1 click, 10 seconds)

Benefits of In-Email Forms

• Higher Completion Rates: No page loads or context switching means more people complete your forms.

• Better Mobile Experience: Mobile users especially benefit from in-email forms that don't require navigating to external pages.

• Faster Data Collection: Get responses in real-time as subscribers engage with emails immediately.

• Improved Data Quality: Less friction means respondents take time to give thoughtful answers.
