Build a funnel with the tools you already have: website, booking page and email

You already own most of a sales funnel: a website, a calendar, an email address and a phone. What is missing is the wiring, so that a visitor who is ready can book a call in a few taps, one who is not can stay in touch, and you can see which channel brought each enquiry. This is how to build a sales funnel from those pieces, in seven steps and mostly on free plans, for a business that sells in a conversation: a call, a visit or a quote.

There is a lot of noise in marketing, and a new tool is the easiest trap to fall into. My advice runs the other way: get the most out of the channels and tools you already use before you add another one.

If funnels are new to you, my guide to what a sales funnel is follows an example from first visit to booked call. This tutorial is part of my complete guide to sales funnels and newsletters.

How to build a sales funnel: the seven steps at a glance

The examples follow a kitchen fitter who offers a free 15-minute call before any home visit. It is an illustration, not a client story: swap in your own service.

Step 1: give one page a single call to action

Start where people already land: the service page Google sends visitors to, or a page made for one campaign. Not the homepage, which has too many jobs to do.

Give that page one action to take, at the top and again at the bottom: a “Book a free 15-minute call” button. Put your phone number next to it, not instead of it. In the cold email campaigns I run for one client, prospects called rather than replied: calling is faster, and people like real human contact.

Around the button, answer what people ask before booking: who the service is for, proof (reviews, photos of real jobs), how pricing works and what happens on the call.

I put clients who edit their own site on Squarespace, because they can change a word or a photo without the layout falling apart. There, the button is a Button block linked to your booking page. For a campaign page, you can hide the menu so that the button is the only way forward: gear icon next to the page in the Pages panel, Navigation tab, then switch off Show Header and Show Footer. On WordPress, a Buttons block does the same job; on Wix, a button element. If you have no site yet, my Squarespace tutorial builds one step by step.

Step 2: add a booking page with two or three qualifying questions

The button opens a booking page where people pick a free slot in your calendar. I use YouCanBookMe: for what I need, it does everything Calendly does, it is easy to find your way around and it costs a little less. Calendly is good too. At the time of writing (October 2026), YouCanBookMe’s free plan includes one booking page connected to one calendar, and Calendly’s free plan one event type. My YouCanBookMe tutorial covers the set-up, from working hours to time zones.

What makes the booking page a funnel step is the questions on its form. After the name and email, pick two or three that tell you whether the call is worth having and how to prepare for it:

1. Which service? A short list of your services, plus “Something else”.
2. Where? The town or postcode, if you travel to clients.
3. When? “Within a month”, “In the next three months”, “Just looking”.
4. How did you hear about us? Google, a recommendation, the newsletter, social media. Step 6 explains why.

Leave the budget for the call, where you can explain what drives the price. Each answer is personal data stored by a third-party tool, so ask only what you will use and name the booking tool in your privacy notice.

Then link your button to the booking page, or embed the calendar on a “Book a call” page. On Squarespace, the embed goes in a Code Block, where JavaScript needs the Core plan or above; on Basic, stay with the button.

Step 3: let the booking tool send the confirmation and reminders

After each booking, YouCanBookMe emails a confirmation to the person and a notification to you, free plan included. Rewrite the default confirmation: it is your first email to a new prospect, and it can do more than repeat the time.

Thank you for booking a call on [date] at [time].
We will call you on the number you gave us.
To make the most of 15 minutes, have a few photos of your kitchen to hand.
In the meantime, here is a kitchen we fitted recently: [link]

Read it on a phone, and check that it still contains the link to change or cancel the booking.

Reminders are usually the first paid feature worth having. YouCanBookMe lists reminder emails and text messages under its paid plans, from Individual upwards, and Calendly’s reminder workflows also need a paid plan. If a no-show costs you a wasted trip, reminders pay for themselves; for a 15-minute call, the confirmation may be enough.

Step 4: offer a sign-up form to people who are not ready

Most visitors will not book on their first visit: some are comparing, others are months away. Give them a reason to stay in touch, such as a monthly newsletter or a one-page price guide, a form to sign up and a welcome email that delivers what you promised.

Two email tools with free plans, at the time of writing (October 2026):

Brevo’s free plan mainly limits what you send each day, MailerLite’s the size of the list; my comparison of newsletter tools sets both against Mailchimp, Kit and beehiiv. On Squarespace, their form’s embed code goes in a Code Block; if it contains JavaScript or an iframe, the Core plan condition applies again.

Keep double opt-in switched on. It means the person confirms by clicking a link in an email before joining the list. It keeps typos, fake addresses and bots out, and it records proof of consent: Brevo’s logs, for example, keep the sign-up, the confirmation email and the time of the click. The GDPR does not mention double opt-in, but its Article 7(1) says that when you rely on consent, you must be able to demonstrate it.

Keep the lists apart, too: someone who booked a call did not ask for your newsletter. Exceptions exist, such as the soft opt-in of regulation 22 of the UK’s PECR and its French counterpart in article L34-5 of the Code des postes et des communications électroniques, but they come with conditions. This is a summary, not legal advice: before you email people who did not sign up, have a lawyer check the rules of their country.

Step 5: add one automation that logs every lead and alerts you

Leads arrive by form, booking, email and phone. Keep them in one list, with an alert as soon as one arrives, so that nobody waits two days for an answer: the settings below cover forms and bookings, and you add calls and emails by hand.

Start with forms, which Squarespace handles without any extra tool. In the form block’s storage settings, connect Google Drive: Squarespace creates a spreadsheet and adds a row for each submission. Do not rename that spreadsheet, or it disconnects, and keep the email notification on as well.

Bookings land in your calendar, and the booking tool notifies you. To copy them into the same spreadsheet, an automation tool can start on each new calendar event and add a row. Set it to pick only events whose title matches your bookings, so that your dentist appointment stays out: on Zapier, the Google Calendar trigger New Event Matching Search does this with a word that all your booking titles share. At the time of writing:

• Zapier: 100 tasks a month free; a booking that adds one row uses one task, as the trigger does not count.
• Make: 1,000 credits a month free, but a scheduled check uses a credit each time it runs, even when nothing new has arrived: checking every hour costs about 720 credits a month.
• n8n: the Community Edition is free if you host it yourself, on a server you keep up to date.

If you would rather depend on none of them, my tutorial to automate lead follow-up for free uses a Google Form, a Google Sheet and a short script: an email alert for each new lead, and a reminder if nobody has called back an hour later.

Step 6: track the funnel with UTM links and a GA4 key event

UTM links. Add three parameters to every link you control that points to your funnel page: the newsletter, your email signature, social profiles, your Google Business Profile, ads.

Use lower case, spell them the same way every time, and never add them to links between your own pages, where they would replace the real source of the visit. My UTM and GA4 tutorial covers naming and the reports to read.

A thank-you page. Create a page that people reach only after an enquiry: in Squarespace, put it in the Not linked section of the Pages panel and switch on Hide page from search results in its SEO tab. Then send people to it:

• after the form: form block, Content tab, Edit Post-Submit, then Redirect (Squarespace help). The redirect does not run while you are logged in, so test it in a private window;
• after a booking: YouCanBookMe sends bookers to your own page on its Professional and Teams plans (YouCanBookMe help), Calendly on its paid plans. On YouCanBookMe, the address must start with https, and an embedded calendar needs the option that updates the whole browser window.

Without a redirect (YouCanBookMe’s Free and Individual plans, Calendly’s free plan), count bookings in the booking tool and read the answers to “How did you hear about us?”.

The key event. In GA4, open Admin > Data display > Events and click Create event. Name it generate_lead, the name Google recommends for a lead, and switch on Mark as key event. Choose Create without code, pick page_view as the source event, enter the address of your thank-you page and click Create (Google’s help page). Do not mark page_view itself, or every page view would count. Counting starts on the day you set it up.

Step 7: test the whole path on your phone

Your prospects will meet the funnel on a phone, so test it there: in a private window (so you are logged out), on mobile data and with a second email address.

1. Open one of your UTM links and tap the button. The booking page loads and fits the screen.
2. Book a slot. The confirmation arrives (check the spam folder too), the event sits in your calendar at the right time, and a row appears in your spreadsheet.
3. Send the form. The thank-you page appears and the alert reaches you.
4. Sign up to your own newsletter. The confirmation email arrives, the link works and the welcome email follows.
5. Open GA4’s real-time report: your visit shows with its UTM source, and generate_lead appears.
6. Cancel the test booking and delete the test contacts, so they do not inflate your numbers.

Run the test again after any change to the site or the tools, and every few months anyway: links break quietly.

When to pay for more, and when to hand it over

Upgrade one piece at a time, when a real problem shows up:

• no-shows cost you trips: pay for reminders;
• you need to know which channel brings booked calls, not just form enquiries: pay for the booking redirect;
• your list outgrows the free plan: compare paid tiers.

A funnel builder such as Systeme.io or ClickFunnels earns its place when you sell online, with checkout pages and upsells; a service sold on a call rarely needs one. Once real visitors arrive, Microsoft Clarity, which is free, shows where they hesitate or leave: the copy, a photo or the layout.

You do not need me for any of this. It gets harder when the volume grows: Pilotech, an air conditioning installer in Paris and the Île-de-France, receives about ten prospects a day, and when the team could no longer keep up, I built an internal app so that nobody forgets to call a prospect back. Until you reach that point, the seven steps above will carry a small team a long way.
