SIGN-UP FORMS
Grow your list with people who actually asked for it
Pop a sign-up form on your website or a landing page, and watch real, interested subscribers join your list — not bots, not typos, not a stranger's old inbox.
One embed, no developer needed
Bot protection built right in
Double opt-in with a single switch
THE PROBLEM
A form without protection fills your list with noise
Put a plain sign-up box on your website and you'll catch more than customers. Bots find open forms fast, and they fill them with addresses that bounce, complain or simply don't exist. Every one of those takes a seat on your list for no reason at all.
Typos sneak in too — a customer in a hurry types "gmial.con" and never sees another email from you. Meanwhile the people who actually meant to sign up get buried under junk entries that drag down the quality of every campaign you send.
None of this is your fault, and none of it has to stay that way. A sign-up form that's protected from the start keeps your list exactly what it's meant to be: people who raised a hand and asked to hear from you.
HOW IT WORKS
From click to confirmed subscriber
Here's what happens between someone finding your form and landing safely on your list.
Drop in the embed
Copy one snippet onto your website, or skip the website entirely and use a landing page instead.
Match your brand
The form picks up your colours and style automatically, so it looks like it belongs on your site.
Confirm, if you choose
Switch on double opt-in and a confirmation email goes out right away from your own sending domain.
Land on your list
Confirmed addresses join your list with their fields already mapped, ready for your next campaign.
IN DETAIL
Three ways your form earns a better list
From where it lives to who gets to join, here's exactly how a Mailer Moose sign-up form works.
ONE EMBED
Works on your website or without one
If you've got a website, one snippet of code is all it takes. Paste it where you want the form to sit and it's live — no plugin hunting, no developer invoice.
No website yet? Put the same form on a landing page and send people straight there from your social posts, your till receipts, or a sign on your counter.
One copy-paste embed
Or a landing page instead
Matches your site's look automatically
Subject: Confirm your subscription

PROTECTED FROM DAY ONE
Bot protection built in, not bolted on
Open sign-up forms are a magnet for automated junk. Bots can fill a plain form hundreds of times an hour, leaving you with a list full of addresses that were never a real person.
Every Mailer Moose form carries protection against automated sign-ups from the moment you publish it, so what lands on your list is what you actually wanted: real people, real interest.
Built-in protection, no setup
Keeps bounces and bots out
List quality protected from day one
DOUBLE OPT-IN
One switch, and every address is confirmed
Flip on double opt-in and anyone who signs up gets an email asking them to confirm, sent from your own sending domain so it looks and feels like you. Only the people who tap confirm join your list.
It's one extra step for your subscriber, and real peace of mind for you: nobody ends up on your list who didn't mean to be there, which matters under Canada's anti-spam law as much as it matters for your open rates.
Confirmation sent from your domain
Only confirmed addresses join
Meets CASL's consent expectations
Subject: Please confirm your subscription
Double opt-in

A list that converts, not just counts
Every sign-up is a real person who wants to hear from you. Here's what that buys you.
Every subscriber asked for it
No guessing who's interested — everyone on your list clicked "sign up" themselves, confirmed if you choose, so your opens reflect real interest instead of a crowded junk list.
Bots stay out
Automated sign-ups get blocked before they ever reach your list, so you're not paying to email addresses that were never real.
Fields ready for personalisation
Whatever you ask for on the form — name, birthday, favourite order — lands in matching list fields, ready for your next send.
On brand, every time
Your form picks up your colours and style, so it looks like part of your business, not a bolted-on box.
No website required
Use a landing page instead and start collecting confirmed sign-ups the same afternoon.
COMPARED
Some forms invite trouble. Yours won't.
A typical sign-up form
- Wide open. Any bot can submit it hundreds of times.
- Single opt-in only. Typos and fake addresses join straight away.
- Generic box. Looks bolted onto the page.
- Confirmation from a shared domain, if it sends one at all. Looks unfamiliar to your subscriber.
- Fields that don't connect. You re-enter data by hand.
Mailer Moose forms
- Protected. Automated sign-ups are blocked automatically.
- Double opt-in, one switch. Only confirmed people make your list.
- On brand. Matches your colours and style automatically.
- Confirmation from your own domain. Looks and feels like you.
- Fields mapped automatically. Ready for your next campaign.
QUESTIONS
What people ask about sign-up forms
What's double opt-in?
After someone signs up, they get an email asking them to confirm. Only confirmed addresses join your list, so every subscriber really asked to hear from you.
Do I need a website to use a sign-up form?
No. Put the form on a landing page instead and share that link anywhere — social posts, your till receipts, a QR code on the counter.
Will the form match my brand?
Yes. It picks up your colours and style automatically, so it looks like a natural part of your site, not an add-on box.
How do you stop bots from filling in the form?
Every form carries built-in protection against automated sign-ups, switched on from the moment you publish it. No extra setup on your end.
What happens to the fields people fill in?
Each field maps to a matching field on your list — name, birthday, whatever you ask for — so it's ready to personalise your very next campaign.
Does double opt-in help with Canada's anti-spam law?
It helps you show clear, confirmed consent, which is central to CASL. You'll still need to identify yourself as the sender and honour unsubscribes within 10 business days.
Can I turn double opt-in off?
Yes, it's one switch. Plenty of businesses leave it on for the extra confirmation step, but the choice is yours.
What happens to my existing list if I add a sign-up form now?
Nothing changes for the people already on it. The form only adds new, confirmed sign-ups going forward.
