What is lead capture?
Lead capture is the process of collecting contact details from people who are interested in what you offer, so you can follow up with them later. The details are usually an email address and a name, sometimes with a company, location, or answer to a question. A person who gives you those details becomes a lead. Common methods include web forms, paper sign-up sheets, trade show badge scanning, and text-to-join.
Lead capture covers the moment of collection. What happens next, the emails, calls, or invitations, is follow-up, and it usually lives in a different tool.
How does it work?
Most lead capture has the same four parts, whatever the method:
- A reason to sign up. People share details in exchange for something: slides, a guide, a discount, a giveaway entry, an answer to their question. That offer is often called a lead magnet.
- The ask. A form, a card, or a text conversation asks for the details. Shorter asks get finished more often.
- Storage. The details go into a list, CRM, or email tool, ideally without anyone retyping them.
- Follow-up. The organization uses the details for what it promised, and anything else the person agreed to.
Quality matters as much as quantity. A sign-up sheet full of unreadable handwriting or mistyped emails looks like a lot of leads and produces few contacts you can reach. Checking each answer when it's entered, and asking only what you'll use, gives you a cleaner list.
Consent is part of it too. The person should know what they're signing up for. When they take the action themselves, like filling in a form or texting a keyword, that's the start of an opt-in.
Why it matters at live events
Live events produce interest in bursts. A keynote ends and 400 people want the slides for about two minutes. A band's set ends and the crowd heads for the exit. A booth gets a rush after a session lets out. The usual tools don't fit those bursts well:
- Paper sheets have to be typed in later, and handwritten emails are hard to read.
- Web forms need people to type a URL and fill in fields on a small screen.
- Badge scanning at trade shows needs a staff member to scan each person, one at a time.
Text-to-join fits the burst because everyone can do it at once from their own phone. People scan a QR code or text a keyword to a short code, answer a question or two, and their details land in your list. On Textiful, that short conversation is called a capture flow; it can send a handout, tag the contact, and send them to Mailchimp, Kit, ActiveCampaign, HubSpot, or other tools.

Key takeaways
- Lead capture is collecting contact details from interested people so you can follow up.
- It works best with a clear offer, a short ask, and storage that needs no retyping.
- Live events produce short bursts of interest, so the method has to work for many people at once.
- Text-to-join lets a whole room sign up from their own phones in the same minute.

Questions people ask
A lead is a person who has shown interest in what you offer and given you a way to reach them, such as an email address. Lead capture is how you collect those details.
Web forms and landing pages, paper sign-up sheets, trade show badge scanners, and text-to-join by keyword or QR code are the most common.
As few as you need to follow up well. Each extra question gives people another reason to stop, so ask for what you'll use and leave out the rest.

Lead magnet
A lead magnet is something useful offered for free in exchange for a person's contact details, usually an email address. Common examples are slide decks, checklists, guides, templates, recordings, and discount codes.
ReadText-to-join
Text-to-join is a way to sign up by text: a person texts a keyword to a short code, or scans a QR code that opens a pre-filled text, and answers a question or two to join a list, get a download, or register for something.
ReadBadge scanning (lead retrieval)
Badge scanning, also called lead retrieval, is how trade show exhibitors collect visitor contact details by scanning the barcode or QR code on attendees' name badges with a device or app. Each scan pulls in the details the attendee gave when they registered for the show.
ReadCapture flow
A capture flow is a short, automated text conversation that starts when someone texts a keyword or scans a QR code. It asks for their details one question at a time, delivers what was promised, and sends the contact on to other tools. Capture flow is Textiful's name for this; it's also called a text-to-join flow.
