What the sequence engine does
Sequences as production infrastructure — not a campaign tab.
One engine across email, SMS, WhatsApp, retargeting, push, in-app — picking channel + send-time + variant per lead, enforcing suppression and quiet hours, auditing every send. Deployable inside your stack, embeddable in agency client books.
Cross-channel orchestration · one engine
Email, SMS, WhatsApp, LINE, retargeting ads, push, in-app messaging — all running on a single sequence engine with shared lead state, not five disconnected platforms duplicating sends.
AI next-best-channel selection per lead
The system reads engagement history, channel fatigue, opt-in state, region, and recent intent — then picks the channel most likely to land for each lead, with confidence and reasoning attached.
Send-time optimisation per recipient
Send-time model learns each lead's response curve — when do they actually open, click, reply — and queues sends at the moment with the highest expected engagement, per their timezone.
Variant selection · A/B without rebuild
Subject, copy, CTA, creative — variants tested live with bandit allocation. The winning variant gets more traffic automatically. No spreadsheet copy-paste, no campaign rebuild to ship a winner.
Frequency caps · suppressions · quiet hours
Per-channel cooldowns, global frequency caps, suppression lists, region-specific quiet hours — enforced before any send. Leads don't get blasted because two flows fired the same hour.
Multi-tenant for agencies — per-client channel inventory
Each client workspace gets its own channel inventory, sender identities, branded templates, and suppression rules. Run nurture sequences across an entire agency roster from one engine.
Where sequences earn their keep
Same engine. Many motions.
Same channel adapters, same picker model, same suppression rules — tuned per motion. Trial-to-paid, cart recovery, B2B mid-market nurture, agency multi-tenant, marketplace lifecycle, and long-cycle services all run on the same engine; only channels, templates, and policies change.
B2B SaaS · trial-to-paid conversion
Email opens trail → SMS book-the-call → retargeting boost → AE Slack alert — all in one orchestrated sequence. AI picks the next channel based on what's working for that specific lead, not a static playbook.
E-commerce · cart recovery + lifecycle
Cart-save Email at 10 minutes, WhatsApp recovery code at 30, retarget on Day 2, post-purchase review at +72h — channel-aware, region-aware, suppression-respecting cart and lifecycle automation.
B2B mid-market · multi-touch nurture
30-touch sequences across email, retargeting, LinkedIn, and direct mail orchestrated by the same engine. AI rebalances the channel mix as the lead's intent shifts week over week.
Agencies · sequences as a productised offering
One engine running channel-orchestrated sequences across an entire client roster. Per-client sender identities, branded templates, channel inventory, and suppression rules — workspace-isolated.
Marketplace · two-sided lifecycle
Buyer-side email + retargeting nurture; supplier-side WhatsApp + SMS onboarding. Same sequence engine, two ICP-aware channel-mix policies, separate suppression and quiet-hour rules per audience.
Long-cycle services · consulting · education
Multi-month nurture cycles where channel fatigue is the biggest enemy. Channel rotation, send-time tuning, and bandit-tested variants keep the sequence relevant when it would otherwise stale out.
Models inside the engine
Multiple models. One auditable send.
Channel picker, send-time optimiser, variant selector, suppression manager — each handles a distinct part of the send decision and combines into one auditable action per lead, per moment.
LLM-backed model that reads engagement history + channel fatigue + opt-in state, returns the next-best channel with confidence and a plain-English reason for the pick.
Learns each lead's individual open/click pattern across channels and timezones. Queues sends at the moment of peak expected engagement rather than a global default.
Multi-armed bandit allocates more traffic to winning variants live. Subject, body, CTA, creative — tested in production, no statistical significance ceremonies before shipping.
Enforces per-channel frequency caps, global suppression lists, and region-specific quiet hours. Idempotent and audit-logged so a replay never double-sends.
Channel adapters wired into every workspace
Every channel a lead lives on — integrated.
Email, SMS, WhatsApp / LINE, ad platforms, push, in-app, CRM — each as a first-class adapter with delivery, engagement, and suppression signals fed into the channel picker.
Solution & technology — not a campaign service
Built to deploy. Built to co-deploy.
Multi-channel orchestration shouldn't be locked behind a managed-service contract. The sequence engine is infrastructure you deploy inside your own stack — directly, with your engineers, or alongside us. Agencies productise it across a client roster; in-house teams embed it into their growth ops; founders run it as the spine of their CRM.
- In-house growth teams — Run the sequence engine as a permanent component of your nurture stack. Your engineers own the deployment, we tune the picker + variant models.
- Agencies + consultancies — Embed it in client engagements with workspace isolation, branded sender identities, and white-label outputs. One deployment, many client books.
- Founder-led ops — Spin up email + SMS + WhatsApp orchestrated nurture in weeks. The system carries the channel-picking + suppression load — no ops team needed to make it work.
Why Axccelerate for sequences
Not a single-channel tool with a calendar.
A sequence engine.
Most marketing automation runs on one channel, with a tab for each other. Our engine runs all channels under one decision layer, with shared state, shared suppressions, and explainability your team and your clients can read.
Pricing
Priced to the deployment, not the send volume.
We scope against your channels, your sequence library, and your client/book footprint before quoting. Agency multi-tenant deployments price differently from a single in-house team — both are first-class citizens.
Your sequence engine — engineered.
30-minute scoping with a senior engineer. You'll leave with a deployment plan, integration sketch, and realistic timeline — whether you're shipping it for your own pipeline or for a client roster.
