Embed your first form question directly in your email

Respondents click their answer inside the email body. Your form opens with that answer already saved. One step instead of three.

Works in every major client Mailchimp, Brevo, HubSpot, ConvertKit Pre-fill carries the answer through

Pick the first question

Choose any single-click question type: NPS, CSAT, star rating, thumbs up/down, multiple choice, yes/no.
Copy the email snippet

Formester generates an HTML block you paste into Mailchimp, Brevo, HubSpot, ConvertKit, or any ESP that supports custom HTML. Each answer is a tracked link back to your form.
The respondent clicks once, finishes in your form

The click registers as their answer. Your form opens with that answer already filled in. They complete any follow-up questions and submit. The whole flow takes 15 seconds.

Client	First-question buttons render	Notes
Gmail (web + mobile)	Yes	Most reliable.
Outlook (web + new desktop)	Yes	Buttons render as styled links. Click-through always works.
Outlook (classic Windows desktop)	Yes	Word-engine fallback. Some styling simplifies; clicks still carry through.
Apple Mail (iOS + macOS)	Yes	Renders cleanly with full styling.
Yahoo Mail	Yes	Buttons render as links.
Mobile webmail (Gmail / Outlook apps)	Yes	Same behavior as web.

Gmail is the visually-richest render. Every other client receives the same buttons as fully-styled clickable links that carry the answer to your form. No client is unsupported.

Custom SMTP for transactional sends

If you send transactional email through Formester directly (notifications, response copies), Formester delivers via your connected SMTP provider. The same identity sends the campaign.

Caveat: Some ESPs (notably older Mailchimp templates) strip non-standard HTML attributes. If the buttons do not render, switch the template to "Plain HTML" or "Code Your Own" and paste the snippet directly.

Caveat: Pre-fill works for every question type, not just the inline one. Hidden fields (UTM parameters, contact ID from your ESP, customer segment) also flow through. Use it to skip "What is your email?" when you already know.

Post-purchase CSAT

Star-rating inline. Open with the order number. "How was your order #1834?" Click. Optional comment field on the page.

NPS tracking

0 to 10 buttons inline, single open-text follow-up on the page. Quarterly send to your customer list.

Event RSVP

Yes / No inline. Pre-fill captures the choice. Form asks for dietary requirements only if Yes.

Webinar follow-up

"Did you attend?" Yes opens a feedback form. No opens a re-watch link form. Conditional branching from a single click.

Support ticket CSAT

Thumbs up / down on ticket close. Down opens a "What went wrong?" form. Up writes the rating and exits.

Content feedback

"Which topic next?" multiple choice. The click is the data point. Optional comment on the form page.

Build the form

Drag-and-drop builder. Add the question you want inline as Q1, follow-ups after. Save.

Open the Share modal

Click Share in the top right. Pick Email. The modal renders a live preview of how each answer button will appear in an inbox and outputs an HTML snippet.

Paste into your ESP

In Mailchimp, Brevo, or wherever you send from, pick a template that accepts custom HTML. Paste the block where the question should appear. Send.

Formester offers a ton of features and my developer loves using it to integrate to various marketing pages. It's quick and easy to create using drag and drop. It allowed me to remove branding unlike Typeform that has branding even in paid plans. Their support is top notch.

Beautiful and easy to use. The templates and the floating button feature with easy-to-use integration with Google Sheet is crazy. I was looking for a simple and beautiful form to put on my website for free.

Does the form actually submit from inside Gmail?

The first answer registers as a click and travels through to the form as a pre-filled value. With Partial Submissions enabled, that value is captured the moment the click lands, even if the respondent never opens the rest of the form.

Will the buttons look right in Outlook?

Yes for new Outlook (web and the rebuilt desktop client). Outlook classic on Windows uses Word's HTML engine and may strip rounded corners or background colors, but the click-through always works. Test against Litmus's client matrix before any major campaign.

Can I track who clicked which answer?

Yes. Every answer button is a tracked link with the respondent's ID baked into the URL. Click data flows back to your form's analytics view. ESPs (Mailchimp, HubSpot) also see the click in their own reports.

What if someone clicks twice or changes their mind?

The latest click wins. The pre-filled answer on the form page reflects the most recent button they tapped. They can also change it on the form before submitting.

Why only one question in the email?

Because every additional question is a reason to delete the email. Inbox attention is measured in seconds. One question, one click, then the form. Multi-question email surveys exist (AMP-for-Email) but render only in Gmail, so they ship lower completion in mixed-audience lists than the one-click pattern.

Will this work with my ESP?

If your ESP supports custom HTML blocks, which Mailchimp, Brevo, HubSpot, Klaviyo, ConvertKit, and Constant Contact all do, yes. Paste the snippet into a "Code Your Own" or "Custom HTML" content block.

Can I make the form anonymous?

Yes. Turn off the hidden ID parameter in the share modal. The form treats the click as a stand-alone submission with no respondent tag. The flip side: you lose pre-fill for any other personalised fields, so use this only when respondent identity is not part of the analysis.

How is this different from sending a survey link?

A link asks the recipient to commit before they know what they are committing to. An inline question shows the first question in the inbox, so the decision is "answer this," not "give us five minutes."
