Opt-In Form Builder for Your Website

What Makes an Opt-In Form Work

An opt-in form is a request, and requests succeed or fail on three things: what you are asking for, what you are offering in return, and how much work the answer takes. Most forms lose on all three. They ask for five fields when two would do, they promise updates rather than anything a person actually wants, and they appear at a moment when the visitor has not yet decided they like you. Fixing that is mostly subtraction. Keep the fields to the minimum, which for a mailing list is usually an email address and perhaps a first name so you can write like a human. Say plainly what someone gets and how often. Ask at a point where you have already been useful, such as the end of an article or the moment someone tries to leave. In BrandBits the same opt-in can appear as a modal, a slide-in or a bar, so you can place it where it fits, and a consent checkbox with your own wording is a single toggle away, which matters if you send marketing email in a jurisdiction that expects proof of permission.

How It Works

One builder, one snippet, and nothing to install or maintain afterwards.

1

Build your campaign

Start from a template or from scratch: popup, floating bar, slide-in or prize wheel. Upload an image or generate one with AI, add a countdown or a two-step question, and match the design to your site.

2

Choose when it appears

Show it on exit intent, after a delay, at a scroll depth, on page load or when a visitor clicks a link. Limit it to certain pages, devices or first-time visitors.

3

Paste one snippet

Add the embed to your site once and every campaign you create afterwards appears through the same snippet. Leads flow straight into your inbox.

Why It Works

Most of the people on your website today will leave without a trace. A well timed message is the cheapest way to keep some of them.

Short forms win

Every extra field costs you subscribers. Ask for an email, add a first name if you will actually use it, and stop.

Consent you can prove

A clear consent checkbox with your own wording keeps your list clean and your marketing defensible.

One form, several placements

The same opt-in can be a modal, a corner slide-in or a bar, without rebuilding it.

Straight into your email tool

Subscribers arrive in Lead Management and can be emailed from BrandBits immediately.

Ways to use opt-in form

What You Can Do

Ask for less, explain the value better, and place the form where you have already earned the answer.

  • Collect email subscribers with a two field form.
  • Add a consent checkbox with wording you control.
  • Show the same opt-in as a popup on desktop and a bar on mobile.
  • Send a welcome email automatically to every new subscriber.
  • Reuse an existing FormGuard form inside the popup.

Everything Popups & Bars Includes

Four Formats

Modal popups, floating bars, corner slide-ins and a spin-to-win prize wheel from the same builder.

Images and Templates

Start from a ready-made template, add your own pictures, choose layouts, animations and placements.

AI Image Generation

No photo at hand? Describe the image you want and it is generated, hosted and dropped into your campaign in seconds.

Exit Intent and Click Triggers

Catch visitors on the way out, or open a campaign the moment they click one of your links.

Two-Step Popups

Ask a yes/no question first. People who click yes convert far more often.

Countdown Timers

Fixed deadlines or a per-visitor timer that starts when they first see the offer.

Social Proof and Teaser Tabs

Show a live signup count under the form, and leave a small reopen tab behind when someone closes the campaign.

A/B Testing

Run two versions of a campaign against each other and promote the winner in one click.

Mobile-Friendly Modes

Bottom sheets and slim banners on phones keep you within Google's popup guidelines.

Leads Flow Onward

Submissions land in Lead Management and are ready for Email Marketing, with impressions, conversions and dismissals all measured.

FAQ

What is an opt-in form?

An opt-in form is a form where someone actively agrees to hear from you, usually by submitting an email address. It is how a permission based mailing list is built.

How many fields should an opt-in form have?

As few as possible. An email address is enough for most lists, and a first name is worth adding only if you will use it in your emails. Every extra field reduces the number of people who finish.

Can I add a consent checkbox?

Yes, with your own wording. That is worth turning on if you send marketing email in a jurisdiction where you may need to show permission was given.

Where do the subscribers go?

Into Lead Management, tagged with the campaign that captured them, and available to Email Marketing audiences and automations straight away.

Can I use a form I already built?

Yes. A popup can display an existing FormGuard form instead of a quick form, so a form you have already designed and protected can be reused.
