The short version: most website platforms let you collect email addresses through a form, but "collect" and "own" are two very different things. WordPress needs a plugin, Squarespace has its own paid email tool with contact limits, Wix bolts email marketing on as a separate app, and Webflow gives you a spreadsheet and nothing else. The question you need answered isn't "can it collect emails" but "can I export that list, in a usable format, whenever I want, without paying extra to get my own data back."
What people mean when they ask this question
When someone asks me "does my platform have an email list feature," they usually mean one of three separate things, and mixing them up is how businesses end up with a signup form that's been quietly collecting names into a black hole for months.
- Form collection - a box on your site where someone types their name and email.
- Storage - somewhere that data lives, that you can see and search.
- Sending - the ability to email that list a newsletter or offer, with unsubscribe links, deliverability tracking, and open rates.
A lot of platforms give you the first two and quietly assume you'll pay someone else, usually them, for the third.
What the big platforms give you, honestly
WordPress gives you nothing out of the box. No form, no storage, no sending. You need a form plugin like WPForms or Fluent Forms to collect the email, and then either a plugin such as MailPoet or a connection to an outside tool like Mailchimp, ConvertKit, or ActiveCampaign to send anything. This surprises people constantly because WordPress feels like it should do everything. It's a content management system, not a marketing platform, and treating it like one is where a lot of small businesses go wrong.
Squarespace has built its own tool called Squarespace Email Campaigns, launched in 2020. It sits inside your site dashboard, pulls your brand colours automatically, and lets you send to your contacts without leaving the platform. The catch is the pricing tiers: as of 2026 you're looking at roughly $5 a month for a Starter tier capped at a small number of sends, climbing to around $48 a month once your list and sending volume grow. It's convenient, but it's not free once you're past a few hundred contacts.
Wix separates form collection from sending almost completely. Wix Forms and Wix Automations will happily capture a name and email and drop it into your contacts list. But to send a newsletter you need the Wix Email Marketing app, which runs on its own pricing, generally starting around $10 a month for a few thousand contacts. I've had clients discover this the hard way, they'd built a beautiful popup, watched the "contacts" number climb, and then found out that number living in your contacts list is not the same as a list you can email.
Shopify is the most generous of the big four here. Shopify Email is built in and free for your first 10,000 emails sent per month, then charges roughly $1 per 1,000 emails after that. If you're running a store, this is one of the better native setups, though it's still worth watching how it handles segmentation once your list passes a few thousand people, because the free tier's automation options are thinner than a dedicated tool like Klaviyo.
Webflow is the one that catches people out most. Webflow form submissions land in a table inside your project settings and can be exported as a CSV. That's it. There is no native sending tool at all. If you're on Webflow, you are building your list on someone else's foundation from day one and need a proper email platform connected via Zapier, Make, or a native integration.
The bit almost nobody tells you before you build the form
Here's the uncomfortable part. Even when a platform does let you send email, the list you're building inside it is usually harder to move than people expect. Export formats vary. Some platforms strip out engagement history, so when you move to a proper email service provider you lose the data on who's opened what, and you start every relationship from zero. And some platforms quietly delete unengaged contacts from your count after a set period to keep you under a pricing tier, which means your "1,200 subscribers" might be 900 by the time you go to export them. Nobody selling you the website builder mentions this at signup, because the point of the built-in tool is to keep you inside their ecosystem, not to make switching easy.
This is not a reason to avoid the built-in tools. It's a reason to check the export function on day one, not the day you decide to leave.
What happened to a client of mine
An interior designer I worked with had a Squarespace site with a nice popup offering a free mood board guide in exchange for an email address. She assumed, reasonably, that every signup was going straight into her email marketing tool. It wasn't. The popup was connected to a generic Squarespace form block that saved submissions into the general "Contacts" panel, not into Squarespace Email Campaigns' subscriber list, because the two had never been linked in her account settings. For four months, roughly 280 people signed up for that guide, received nothing, and were never added to a single send. She only found out when she went looking for a spike in signups after a Pinterest push and couldn't find the names anywhere in her campaign tool. Those 280 people were sitting in a contacts export she'd never opened. That's four months of warm leads, people who'd already said yes to hearing from her, gone cold with zero emails sent. It took twenty minutes to fix once she knew where to look, but the damage to that particular batch of leads was already done.
How to check your own platform in five minutes
- Find your form or popup settings and check where submissions are stored. Look for the words "list," "audience," or "contacts," not just "form responses."
- Send yourself a test signup right now, using an email address you check, and time how long it takes to arrive in whatever tool you use to send campaigns.
- Try to export your list as a CSV today, before you need to. If the export button is missing, greyed out, or locked behind a higher pricing tier, that's your answer about who really owns this list.
- Check for an unsubscribe link on any automated email your site sends. If there isn't one, you're not legally compliant to send marketing email from that list at all, under UK GDPR or the US CAN-SPAM Act.
- Look at your form's conversion rate against your site traffic. If you don't know that number, it's worth comparing yours against typical figures in our piece on average conversion rates for small business websites, because a broken sync is often invisible until you notice signups aren't matching traffic.
When to stop relying on the built-in tool
I generally tell clients to move off the native platform tool once one of three things happens: your list passes around 2,000 to 3,000 contacts and the platform pricing starts competing with a proper email service provider, you want automation more advanced than "send one email to everyone who signed up," or you're running paid ads and need your list synced with something like Facebook Lead Ads without manual exports. If that last one is your situation, it's worth reading through how to connect your email marketing with Facebook Lead Ads without losing half your leads, because the sync problem I described above with Squarespace is almost identical to what happens with ad platforms that don't talk to your list.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Tools like Mailchimp, ConvertKit, ActiveCampaign, and Klaviyo all connect to every platform I've mentioned, usually through a native integration or a Zapier bridge, and they give you segmentation, tagging, and automation sequences that no website builder's native tool comes close to matching. The website platform's job is to build the site. Growing a list into a genuine sales channel is a different job, and pretending your site builder can do both indefinitely is how businesses end up with the Squarespace situation I described above, a list that exists but isn't working for anyone.
Where this matters most
If you're building anything with a paid product behind it, a membership, a downloadable guide, or something like an online course, your email list is doing more work than your homepage. Course sales, in my experience and in most of the data I've seen from course creators, come overwhelmingly from email sequences rather than cold website traffic. If your platform's native list tool caps you at 500 contacts or hides your export button, you're building your entire launch strategy on a foundation you don't fully control. Check it before you build the funnel, not after your first launch underperforms and you go looking for why.
It's also worth checking your form submissions against your actual site analytics. If Google Analytics shows a healthy number of what it counts as active users on your signup page but your list isn't growing to match, that gap is usually the sync problem, not a traffic problem.

Frequently asked questions
Does Squarespace have a built-in email list feature?
Yes. Squarespace Email Campaigns is built into the platform and lets you send newsletters directly from your site dashboard, with pricing starting around $5 a month on a limited tier and rising to roughly $48 a month for larger lists as of 2026. You still need to check that your signup forms are linked to the Email Campaigns subscriber list and not just saving to a general contacts panel.
Can I collect emails on WordPress without a plugin?
No. WordPress has no native form or email storage feature at all. You need a form plugin such as WPForms or Fluent Forms to collect the email, and a separate tool or plugin, such as MailPoet or a Mailchimp connection, to store and send to that list.
Is Shopify Email free?
Shopify Email is free for the first 10,000 emails you send each month, then costs roughly $1 per 1,000 emails after that, making it one of the more generous native email tools among the major website platforms.
What happens to my email list if I switch website platforms?
It depends entirely on whether the platform lets you export your subscribers as a CSV file with their email addresses and, ideally, their engagement history. Some platforms make this easy, others hide the export behind a paid tier or strip out useful data like open rates, so it's worth testing the export function on day one rather than assuming it will work when you need it.
