How to grow your SMS list with website pop-ups
How to design a website pop-up that collects SMS subscribers with proper consent: offer, timing, form fields, consent wording and the first message.
·2 min read
Most people who visit your website leave without buying or getting in touch. A pop-up that invites them to join your text list gives you a way to follow up with the ones who are interested.
Done well, it converts visitors without annoying them. Done badly, it gets closed instantly and can create consent problems.
Offer something worth a phone number
People share their number when they get something clear in return: a first-order discount, early access to sales, appointment reminders or a free guide. Say what they will receive and how often, so the sign-up feels like a fair trade.
Timing and design
Show the pop-up after a visitor has engaged, for example after scrolling halfway or spending some time on the page, or when they move to leave. Make it easy to close, keep the form to one or two fields, and make sure it works well on phones, where most visitors browse.
- ✓Trigger after engagement or on exit intent.
- ✓One or two fields: phone, and optionally first name.
- ✓An obvious close button.
- ✓Mobile-first layout.
Consent wording and the first text
Place consent language directly under the phone field: it should name your business, say that marketing texts may be sent with automated technology, state that consent is not required to purchase, mention that rates may apply and that replying STOP opts out, and link your terms and privacy policy. Send a welcome text right away that delivers the promised offer and confirms how to opt out.
Key takeaways
- →Offer a clear reason to share a phone number.
- →Trigger the pop-up after engagement, not instantly.
- →Put full consent wording under the phone field.
- →Deliver the promised offer in an immediate welcome text.

Frequently asked questions
Should I ask for email and phone in the same pop-up?
You can use a two-step form: email first, then phone. Keep each step short and get SMS consent separately.
Is double opt-in required for pop-ups?
Not always required, but a confirmation text strengthens your consent record and keeps typos off your list.
