How to Create an Opt-in Form in Flodesk

Opt-in forms help you grow your email list by collecting subscriber information directly from your website, blog, or social media. Whether you have a website or not, Flodesk offers flexible form types to match your brand and marketing goals.

This guide walks you through the types of opt-in forms in Flodesk and how to create, customize, and embed or publish them.

Important: For new members who joined Flodesk after April 2, 2025, double opt-in is turned on by default for opt-in forms. Be sure to review and customize your double opt-in email and confirmation page under Account settings > Opt-in setup.
Learn more about double opt-in here.

You can choose from four form types depending on how and where you want your form to appear:

Please note: if you’re on the free plan, your form can only collect subscriber data and move this data into a segment you specify in Flodesk.

To trigger a freebie email send or a welcome sequence once your subscribers are moved into the segment associated with your form, you'll need to upgrade to a plan that includes workflows.

1. In your Flodesk account, go to the Forms tab

2. Click + New form

Select:

• Popup – for overlaid forms on your website, comes with embed code

• Inline – for embedded forms, comes with embed codes

• Full page – standalone URL, no embed codes

• Link in bio – ideal for social media landing pages, comes with standalone URL, no embed codes
  

Not sure which one to choose? You can always go back and start a different form type later.

• Click Customize it to open the builder

Select an existing segment or create a new one. This is where new subscribers from your form will be stored.

Tip: Use a dedicated segment for each form to keep your audience organized and power automations.

• If using a Full page form, you can enable Form sharing so subscribers can share the form link with others. When turned on, the "Share with a friend" button will be visible. The button will inherit the font color that you choose for your thank you message. The font style cannot be edited and will always be Helvetica /Arial.

• Share it anywhere: your social media, emails, or blog

• On the free plan, forms can collect subscribers into a segment only. To send automated emails, upgrade to a paid plan with workflow support.

Creating a Flodesk opt-in form is easy and flexible:

1. Choose from Popup, Inline, Full page, or Link in bio

2. Customize the design, fields, and thank you message

3. Assign a segment for subscriber organization and automation

4. Embed on your site or share the link (depending on form type)

Is it possible to customize the design of a Flodesk inline form using custom CSS?

Yes. Select the "Advanced options" (bottom right corner), and then click the "Get raw HTML code". On the next screen, select "Disable CSS". This disables all form styles created in the Flodesk builder. You will have to style your form with custom CSS.

I accidentally deleted a form. Is there a way I can retrieve it?

If you have deleted a form from your Flodesk account, currently there's no way to get it back. To avoid accidental deletes, you will need to confirm that you want to proceed with deleting before tit happens.

If the form is already deleted, you would need to create a new form and replace the embed codes on your website (that is if it was a popup or an inline form).
