GuideEvery field you add costs you leads.
That is the only rule of lead capture forms that holds everywhere. The interesting question is which fields are worth paying for — and for most stores the honest answer is none of them.
Field by field.
What each one costs, and when it earns its place.
Email address
AlwaysThe only field that is genuinely required. Everything else is a trade you are choosing to make.
First name
Rarely worth itUsually added so future emails can say “Hi Sarah”. That personalisation is worth less than the completions it costs, and most email platforms handle a missing name gracefully. Collect it at checkout, where they are giving you a name anyway.
Phone number
Only as its own campaignSMS consent is legally distinct from email consent in most regimes and asking for both in one form muddies which one you were given. If SMS matters, run a separate campaign for it rather than a second field.
Birthday
Later, not hereIt powers a birthday campaign that will not run for up to a year. There is no reason to pay for it in completion rate today when a subscriber will happily give it to a preference centre next month.
Company or job title
Only if you qualifyThis is where B2B lead capture genuinely diverges from ecommerce. If a human will follow up and their time is expensive, filtering at the form is rational. If nobody follows up individually, you are paying for a field you will never read.
What we do with a captured lead.
We sync the email address or phone number, and nothing else to whichever of the 6 connected providers you use. No enrichment, no scoring, no CRM — the capture layer hands off to the tools that are better at the next step than we would be. If the popup is meant to feed a sales process rather than a mailing list, that hand-off is the part to check carefully before buying anything in this category.
Lead capture, answered plainly.
Including whether a popup can qualify a lead. It cannot, here.
A popup whose purpose is to collect a contact detail — usually an email address — in exchange for something the visitor wants. It differs from an announcement or promotional popup in that it has a form and a specific downstream job: getting a person onto a list where you can reach them again.
One, unless you can name what the second field will be used for and when. Every additional field reduces completions, and the majority of the extra data collected at signup is never used, or is used for something that could have waited. The exception is genuine qualification: if a person will follow up individually and their time is costly, filtering early is worth the lost volume.
Usually not. The common justification is personalising future emails, and that is a small gain against a measurable cost in completion rate. You will get the name at checkout from anyone who buys, and email platforms handle a missing first name without breaking. If you want it, ask in a welcome email rather than at the door.
Mostly a difference in vocabulary and in what happens next. “Lead capture” carries the implication that someone will follow up — it is the B2B phrasing — while “email signup” usually means the address joins an automated program. The form looks the same; the field count often should not, because qualification only pays when there is a human at the other end.
In BetterPopup: it syncs the email address or phone number, and nothing else to whichever of the 6 connected providers you use, and appears in the dashboard. With double opt-in selected it stays provisional until confirmed, so unconfirmed addresses never reach your provider. There is no enrichment step, no scoring and no CRM — those live in the tools you already run, and we would rather point at them than pretend to replace them.
Not here, and this is worth being exact about because the category talks loosely. Our mini-quiz is a first-click warm-up, not segmentation — answers are not stored or synced — the answers are not stored and not sent anywhere. If you need answers attached to the contact record for routing or scoring, you want a dedicated quiz or form tool, and you should ask any vendor claiming otherwise which field the answer lands in and whether you can export it.
Audience rules. There are 6 conditions, the first being whether this person has already signed up, and one that reads the marketing cookies other providers set — so someone who joined a list elsewhere can be excluded too. Both 2 opt-in modes respect it.
