Email (Only) Signup Collector:
Capture Email via SMS,
Build Both Lists Simultaneously
The Email Signup collector is a two-step flow — the contact opts in via SMS (capturing their verified phone number), then OTTO asks for their email address in the reply. One opt-in event builds both your SMS list and your email list simultaneously, with TCPA consent documented on both.
The Email Signup collector is the simplest multi-channel list building tool in TextingOnly. No complex configuration — just an entry point, a one-question email prompt, and a compliance confirmation. The power is in what it builds: a verified, dual-channel contact record from one SmartLink tap.
The Complete Flow
Unlike qualification collectors (Custom Questions, ITR), the Email Signup collector does not fire an email lead alert to your team. It’s a list-building tool — the “output” is the contact on the list, not a lead notification. Monitor list growth in the Lists dashboard and use outbound campaigns to engage the built list.
Common Use Cases
Add a SmartLink CTA to existing email campaigns: “Text JOIN to get our SMS deals.” Subscribers tap in from email, opt into SMS, and both channels now reach them.
QR code on the receipt or counter: “Join our text list for exclusive deals.” Customer scans, opts in, provides email. One QR builds both lists from every transaction.
QR on the booth banner: “Text to stay connected.” Attendee opts in during the event — you capture their verified phone and email simultaneously without a paper sign-up sheet.
SmartLink in Instagram or TikTok bio: “Join our inner circle.” Followers opt in from social, moving from a borrowed audience (social platform) to an owned one (your SMS + email list).
Connecting to Outbound Campaigns
The Email Signup collector becomes a list-building engine when combined with outbound campaigns. Associate the collector to a named list — every opt-in auto-populates it. When you’re ready to engage the list, create an SMS campaign targeting it. The lifecycle loop:
