Automate

Journeys that run while you sleep

Welcome new subscribers, recover abandoned carts and fire event-triggered journeys. Each step reports its own sends, clicks and click rate, with quiet hours and frequency caps to keep you welcome.

  • Welcome and multi-step drip journeys
  • Cart, back-in-stock and price-drop triggers
  • Per-time-zone and smart send times
A welcome journey in relaybell: a trigger when someone subscribes, timed message steps, a preview and the step's sends, clicks and click rate.

Target and measure

Reach the right people, then see what it earned

Build segments from country, language, page, device, tags and behaviour, with a live count as you refine the rules. Every send reports delivery, clicks, conversions and the revenue it drove.

  • Saved segments and exclude rules
  • A/B tests with an automatic winner
  • Revenue and conversion attribution

FAQ

Questions, answered

Straight answers — no fine print. More on the pricing page and in the setup guide.

Is relaybell really free?
Yes. During early access relaybell is free for early adopters — no credit card required. You get up to 5,000 subscribers, unlimited notifications and every core feature.
Do my users need to install an app?
No. Web push works right in the browser. Visitors tap “Allow” once and start receiving notifications — nothing to download, no app store.
Which browsers and devices are supported?
Web push works across Chrome, Edge, Firefox, Opera, Brave and Samsung Internet on desktop and Android — and on Safari, including iPhone and iPad on iOS 16.4+ (after adding your site to the Home Screen). It's standards-based Web Push (VAPID), so coverage keeps growing.
What counts as a subscriber?
A subscriber is one browser on one device that has opted in to your notifications. If someone opts in on both their laptop and phone, that counts as two subscribers.
What happens after early access ends?
Paid plans arrive later — but early adopters lock in founder pricing. You will always get plenty of notice, and nothing changes for you mid-flight.
