The pop up offers a guide, a discount, a template. The visitor types an email to get it. Somewhere in the small print, that email also became a marketing subscription, and both parties will remember that moment differently when the first campaign lands.
Lead magnet consent is not hard to do properly. It just requires giving up a conversion trick, the bundled signup, in exchange for a list that can actually defend itself.
Delivery is not consent
Exchanging an email for a resource is a transaction. The visitor agreed to receive the resource, full stop. Treating that act as agreement to ongoing marketing stretches the original act past anything the visitor understood themselves to be doing.
The clean pattern is two steps in one form: the email field that fulfils the offer, and a separate optional checkbox for marketing, unticked, in plain words. People who tick it are genuinely yours. People who do not still got what was promised, which is how trust in the brand survives.
Writing the sentence people see
The consent line beside the box does the legal and the human work. It should say what will be sent, roughly how often, and that unsubscribing is easy. Vague invitations to receive updates and offers from us and partners are where complaints are born.
Write the sentence you would accept as a visitor who has never heard of your company. Short, specific, no partner fog. Then freeze that wording under version control, because it becomes evidence later.
Discount pop ups: the awkward middle
First order discount pop ups sit between transaction and marketing more honestly: the discount is delivered by email, so an email is plainly required, but ongoing campaigns after the discount code are a separate ask again.
The pattern that holds up is to send the code as the promised transaction, then let the welcome flow ask, clearly, whether the shopper wants to stay subscribed. Smuggling them onto the full list from a discount claim is the complaint pattern regulators see constantly.
Evidence and list hygiene
For every subscriber, keep the timestamp, the form and wording version, and the choice made. If your tooling cannot show you which sentence a contact agreed to, your consent records are decorative, however large the list is.
Review pop up sourced subscribers separately in your metrics. They unsubscribe and complain at higher rates than deliberate signups, and watching that gap tells you whether your wording is honest or merely effective.

Frequently asked questions
Can I require marketing signup to deliver a lead magnet?
Requiring it makes the consent neither freely given nor clearly separate from the transaction, which undermines it in strict regimes and in subscriber trust everywhere. Deliver the resource on the email alone and ask for marketing as its own choice.
Is a pre ticked marketing box ever acceptable?
No. Pre ticked boxes are the classic invalid consent pattern, named in guidance and enforcement for years. The visitor must take a positive, unambiguous action. An unticked box they choose to tick is the whole mechanism.
What records should I keep for pop up signups?
Timestamp, source form, the exact consent wording version shown, and the choice state. Also keep later changes, especially unsubscribes, linked to the same record. That chain is what answers a complaint months later.
Why do my pop up subscribers complain more?
Because many of them never understood themselves to have subscribed. Bundled and rushed signups manufacture reluctant subscribers. Separating the marketing ask lowers raw list growth slightly and improves every quality metric after it.
