Live social proof
that grows itself
Every click (or open) bumps a live engagement counter in your email image — and everyone who opens afterward sees the bigger number. “1,501 people are loving this” builds with the audience, so urgency compounds after the send goes out.
The audience creates the urgency
Social Signals is a live engagement counter rendered as an email image. Count from clicks (then forward to your destination) or from opens — set once per image. After the campaign goes out, you do nothing: every interaction bumps the number, and the next open shows a bigger count.
nuid parameter — no extra setting required
Fresh counters from a single design
Append signal_key=ANY_VALUE to the image URL and each distinct value
keeps its own independent count. Reuse the same creative in every campaign with
a new key for a fresh counter — or pass a product merge tag and one image powers
per-item counts across an entire catalog.
signal_key value per campaign = fresh counter with zero reconfiguration
A counter you design, not a fixed badge
The Signal Counter is one layer on the full Studio canvas. Combine it with text, images, shapes, merge tags, data sources, and weather fields so the social-proof number sits inside a creative that matches your brand — not a bolted-on widget.
Cold starts that never look awkward
“3 people love this” is worse than nothing. Social Signals gives you real controls so low-volume sends still feel credible — without faking engagement.
Seed offset
Optionally add a fixed offset to the displayed number. Thresholds always compare the genuine count — never the seeded display.
Minimum count
Below your threshold, show fallback text (“Be the first ❤”) or hide the counter layer entirely until real engagement lands.
Default image threshold
Serve an uploaded default creative until the real count reaches a chosen number — then swap to the live counter design automatically.
Live in 3 steps
Design once. Drop in the image. Watch the count climb.
Design your creative
Start from a ready-made example template, upload a background, or open a blank canvas. Drop a Signal Counter layer and style it like any other text.
Choose how you count
Count clicks (with a destination URL) or opens. Add nuid for once-per-subscriber. Use signal_key for a fresh counter per campaign or product.
Send & watch it grow
Drop the image into your email. Counts update at low volume so test sends show movement right away — and a one-click reset zeroes every counter before the real send.
Where live social proof converts
Flash sales & FOMO
“X people are loving this deal” growing in real time across the send — urgency that compounds as the campaign performs.
Launches & events
Show live interest building on a product announcement or registration push — “2,340 are interested” that updates every open.
Per-item catalog counts
One design, a product merge tag as signal_key — independent live interest counts across retail, travel, or real-estate listings.
Loyalty & community
Celebrate members joining, redeeming, or engaging — social proof that makes the next subscriber feel like they are not alone.
Limited-time offers
Pair a Social Signal with a countdown timer — scarcity from the clock and social proof from the crowd in the same email.
Content & editorial
“X readers saved this story” or “Y people are reading this” — engagement signals that pull the next open deeper into the issue.
Social proof beside your full toolkit
Drop a Signal Counter next to countdown timers, personalized product shots, weather modules, and rule-based creatives. Every click does double duty — engagement for you, content for the counter — so the feature compounds with normal campaign goals instead of competing with them.
Works because it’s just an image
Social Signals render as standard images with optional click-through links. No JavaScript, no AMP, no special client support. If your ESP supports images and links — and they all do — Social Signals work.
