Subscribe forms
Subscribe forms are how new contacts sign up for a mailing list. Each form is linked to one mailing list — when someone fills it in, they're added as a contact to that list. You decide which details you collect: email address, first name, company, topic preferences, and more.
Subscribe forms are how new contacts sign up for a mailing list. Each form is linked to one mailing list — when someone fills it in, they're added as a contact to that list. You decide which details you collect: email address, first name, company, topic preferences, and more.
A subscribe form stays linked to the same mailing list — to send signups to a different list, you create a new form. On accounts that use a single mailing list, you won't pick a list at all: new forms are attached to your default list automatically.
Creating a subscribe form
- Choose a name and mailing list. Click "New subscribe form", give it a clear name, and select the mailing list that new signups should be added to.
- Design the form. Add the fields you want to show — email is required, all other fields are optional. Per field you can set the label, placeholder and whether it's required, so the same field can be optional on one form and required on another.
- Set what happens after signup. You can show a thank-you page, redirect to an external URL, or send a confirmation email for double opt-in.
- Finish up. Set the status to Completed — only completed forms can be shared or used on your website. From the overview you can then copy the public URL, grab an embed code, or open a live preview.
The form wizard, step by step
1. Subscribe form
This is the form your visitors fill in. Open the editor to arrange the fields: email is required, everything else is up to you. Per field you set the label, placeholder and whether it's required — the same field can be optional on one form and required on another.
2. Confirmation page
New subscribers see this page right after submitting the form. Its job is to say "check your inbox": a confirmation email is on its way and they need to follow the link in it to finish signing up. Design the page in the editor, or redirect to a page on your own website instead.
3. Confirmation email
The double opt-in email. It proves the new subscriber is a real person with access to that inbox, and keeps bots off your list. Set the sender name, subject, preheader and the addresses to send from and reply to, then design the email itself — including the confirm button — in the editor.
4. Thank-you page
After clicking the confirmation link, the new subscriber lands here — the signup is now complete. A short thank-you is the custom; the rest is up to you. Like the confirmation page, you can design it in the editor or redirect to your own website.
5. Thank-you email
Sent once the subscription is confirmed — a welcome in their inbox. This step is optional: use the toggle to skip it if you'd rather not send one. If you do send it, the settings and editor work the same as the confirmation email.
6. Your form is ready
The form is now Completed and ready to share. Copy the public URL, grab the embed code for your website, or open a live preview to walk the full signup flow yourself before you share it.
Subscribe form, not popup (yet)Today the wizard builds a hosted, page-style form — reachable at its own URL or embeddable on your site. A popup-style form (an overlay on your existing site) is on the roadmap but not available yet.
Double opt-inWith double opt-in, new signups must first confirm their email address via a confirmation email. Until they do, the contact stays unconfirmed; after confirming, it's automatically activated for the mailing list. It helps prevent typos, spam signups and unwanted subscriptions.
Topic preferencesIf the linked list uses topics, you can show them on the form. New subscribers then pick which subjects they want to hear about, and those preferences are saved straight to the contact.
One form per mailing listA subscribe form is linked to one mailing list, and that link can't be changed after the form is created. To send signups somewhere else, build a new form.
Test before you shareUse the live preview to test the form yourself before you publish. Walk the full signup flow, including any confirmation emails, redirects and thank-you pages, so new contacts get a good first impression.
Can one form add a contact to multiple lists?
No — each subscribe form sends signups to exactly one list. To collect for multiple lists, build a separate form for each.
How do I embed the form on my website?
On the overview row's actions, choose the publish/embed option to copy a snippet you paste into your site's HTML. Alternatively, link directly to the form's public URL — the form is fully usable on its own page without an embed.
Why is my new signup showing as Unconfirmed?
You have double opt-in enabled. Unconfirmed contacts are real signups who have not yet clicked the confirmation link in the email we sent them. They are not skipped because anything is wrong — they are skipped to protect you from sending to addresses that have not actually verified themselves.
A required field is missing on my form — what do I do?
Open the form in the editor, drag the field into the layout from the side panel, then use the fine-tune panel on the right to toggle "required" for that specific form. The same field can be optional on one form and required on another.
Can I change the redirect URL after publishing?
Yes — open the form, jump to the post-signup configuration step, change the URL, save. The change applies to every subsequent signup; previous signups are unaffected.
