Collect leads from your posts

Lead capture is turned off in PostSignOff right now. You won’t see the Lead Capture section, the Email capture choice or the Contacts page. Any capture form link shows “This form isn’t available.” This page explains how lead capture works for when it comes back.

Put a link to your capture form (your branded signup page) in your posts. Readers who click it can leave their email. You can ask for their name and phone number, too. Each signup lands on your Contacts page.

Before you start

Lead capture needs a paid plan. If your plan doesn’t include it, the Lead Capture section on the Brands page shows this instead of its settings:

“Add a capture link to any post and collect emails — plus names and phone numbers — through a branded signup page. Available on paid plans — upgrade to unlock.”

Select upgrade to unlock to go to the Billing page.

Each brand has its own capture form and its own link.

Steps

1. Check that your form is on

  1. Select Brands in the sidebar and pick a brand.
  2. Find the Lead Capture section. Its Enabled box starts out checked.
  3. If the box isn’t checked, check it and select Save.

2. Set up your form

In the same section, set:

  • Headline: the title at the top of your form. Up to 120 characters.
  • Collect name / Collect phone: check either one to add that field to the form. Name starts out on and phone starts out off. Email is always asked for.
  • Consent text: the words next to a box people must check to sign up. Up to 500 characters. Each contact’s record saves the consent text from their latest signup. So update it whenever your consent wording changes.
  • Thank-you message: what people see right after they sign up. Up to 300 characters.

Select Save. The button stays grayed out until Headline, Consent text and Thank-you message all have text. When the save works, Saved shows for a moment.

The Public form link box shows your form’s web address. Select Copy. The button says Copied! for a moment.

A link you copy here isn’t tied to any post. People who sign up through it show as Direct.

4. Add a capture link to a post

  1. Open the post from the Posts page.
  2. Put your cursor where the link should go.
  3. Select Capture in the editor toolbar.
  4. In the Add a link dialog, keep Email capture picked. It’s the default.
  5. Select Insert. The link goes in at your cursor. If you selected text first, the link replaces it.

Each link you add this way is tied to that post. When someone signs up through it, that post shows as their Source post on the Contacts page. You see the start of the post’s text as a link, or View post if there’s no text to show.

Selecting New link swaps your form’s web address for a brand-new one.

That breaks every copy of the old link right away. It breaks links in posts you’ve already published, too. Anyone who clicks an old link sees “This form isn’t available.” There’s no way for them to get to the new form from there.

Before it changes, you see “Generate a new link?” and “The current link stops working immediately — posts that already include it will point to a dead page.” Select Generate new link to go ahead.

Only do this if you have a real reason, for example the link is being abused. Otherwise keep the same link, so links in older posts keep working.

How signups show up in Contacts

New signups show up on the Contacts page for that brand. If someone signed up through a link you added to a post, that post shows in the Source post column. Signups through your plain form link show Direct.

If the same email signs up again on the same brand’s form, PostSignOff updates that contact. It doesn’t add a second one.

Your plan caps how many contacts you can keep, counted across all your brands. The Contacts page shows {used} of {limit} contacts stored. On a plan with no cap, it reads {used} contacts stored.

When you hit the cap, new emails can’t sign up. They see “This form is not accepting submissions right now.” under the form. Emails you already have for that brand can still sign up again. To make room, delete old contacts or upgrade your plan.

If something goes wrong

“Your capture form is disabled. Enable it in brand settings.”: You see this in the Capture dialog, and “brand settings” is a link. The form is turned off for this brand. Check Enabled in the Lead Capture section and select Save.

“Lead capture is available on paid plans.”: You see this in the Capture dialog. Your plan doesn’t include lead capture. Select Upgrade to unlock to go to the Billing page.

“Could not load your capture form. Try again.”: The Capture dialog couldn’t reach PostSignOff. Close the dialog and try again.

“Could not load lead-capture settings.”: The Lead Capture section couldn’t load. Refresh the page.

If a save fails, no message shows. So if you don’t see Saved after you select Save, refresh the page and check your settings.

“Verification failed — please try again.”: A visitor sees this on your form when its bot check fails. They can try again.

Your form shows “This form isn’t available.”

Visitors see this one message for several reasons, on purpose. The page never says which one. If someone tells you your form is dead, check these:

  1. Is lead capture turned on in PostSignOff? Right now it’s off, so every capture form link shows this message.
  2. Is your form turned on? On the Brands page, check that Enabled is checked in the Lead Capture section.
  3. Does your plan include lead capture? If the section shows the paid-plans message instead of your settings, it doesn’t. Upgrade to bring the form back.
  4. Was the link changed? If someone selected New link after the link was shared, the old link is dead for good. Copy the current Public form link and share or add that one instead.

A full contacts cap doesn’t cause this message. Your form still loads. Only new emails get turned away, with the message in the section above.
