Predicate-based segments, drag-drop designer, RFC 8058 one-click unsub on every send. Built for teams who care about open rates and unsubscribes equally.
Mailchimp tops out at 5 conditions per segment. Our DSL supports arbitrary nesting. Segments evaluate live against your contact base — campaigns hit the live count, not a frozen snapshot.
What you preview is what every Outlook installation sees. Block-based editor, MJML under the hood, exports as email-safe HTML at send time.
We learn each recipient's best engagement window over the first 3 sends. The histogram tightens; open rates climb.
Run subject-line tests. We pick the winner once the confidence interval beats a threshold you set.
Gmail and Yahoo's bulk-sender requirements (5,000+ emails/day) demand it. We default it on; competitors charge extra to enable it.
If your Black Friday blast tanks Gmail's view of one IP, we see it before you do — and route subsequent sends around it for 24h.
Trigger an abandoned-cart flow.
await relayly.events.create({ email: customer.email, metric: "Cart Abandoned", properties: { cart_id: cart.id, cart_value: cart.totalCents / 100, items: cart.items.map(i => i.title), }, }); // Your "Abandoned Cart" flow in the dashboard: // Wait 30 min → Send "still thinking?" email // Branch on opened? → Yes: send 24h-later "10% off" // → No: send 48h-later "we miss you"
The honest answers to "but why not just X?".
Klaviyo bills by active profile — your cleaning effort doesn't reduce the bill. We bill by send volume only. At 200k profiles + 1M sends/mo: Klaviyo $720, Relayly $130. The migration script keeps your segments and templates intact.
Mailchimp's audience-based pricing punishes growth. Their segment builder maxes at 5 conditions. Our predicate DSL has no such cap, and migration carries Customer Journeys → Flows automatically.
You can't move sender reputation between providers. Use our 14-day warmup curve in parallel — most teams see equivalent inbox rates by day 7. Run dual-send for a week and compare; if Relayly isn't equal-or-better, we'll spot you 10,000 more verification sends.
