The challenge

Email marketing is dying. Messaging marketing has no tooling.

Email open rates have been sliding for a decade. Marketers know it. They also know WhatsApp and Telegram messages get read 4–5× more often. The reason most teams don’t use messaging for campaigns isn’t skepticism — it’s the absence of a Mailchimp-equivalent. There’s no obvious way to upload a list, write a compliant message, schedule a send and read a report.

SaleBot was built to be that Mailchimp-for-messaging. Drag-and-drop campaign builder, AI-assisted copy generation, smart segmentation, A/B testing, scheduled and recurring sends, full analytics dashboard — across both WhatsApp Business Cloud API and the Telegram Bot API from one workspace.

Our approach

Two channels behind one abstraction

WhatsApp and Telegram have very different APIs, very different rate limits and very different content rules. We built an internal Channel abstraction that hides those differences from the marketer’s view: a campaign is a campaign. Behind the scenes, WhatsApp messages go through template approval; Telegram messages don’t; both get queued, rate-limited per the channel’s rules, and reported on with a unified delivered/read/clicked schema.

The AI campaign builder uses OpenAI under guardrails: it can suggest copy, rewrite for tone, translate to 30+ languages and generate template variants for A/B testing — but the marketer always sees the final text before it goes out, and every prompt+output pair is logged for compliance reviews.

Buyer FAQ — building a marketing SaaS like SaleBot

SaleBot is a multi-tenant marketing SaaS for WhatsApp and Telegram — a Mailchimp-style workspace with campaign builder, AI copy assistance, segmentation, scheduling, A/B testing and analytics. Bulk senders are a single feature; SaleBot is the whole marketing stack around messaging.

Industry benchmarks put WhatsApp and Telegram read rates at 80–98% versus 18–22% for email. Click-through rates are typically 5–7× higher. The trade-off is content rules (Meta template approval) and per-recipient cost — both of which SaleBot is built to manage.

A white-label SaleBot deployment with your branding, billing and onboarding takes 8 to 12 weeks. A fully custom multi-channel marketing SaaS (WhatsApp + Telegram + SMS + email) takes 16 to 26 weeks.

Yes. AI (OpenAI under guardrails) writes campaign copy, suggests A/B variants and translates to 30+ languages. Every prompt and output is logged for compliance, the marketer always sees the final text before send, and AI is opt-in per workspace — never silently in the path.

Yes — both channels run behind a single Channel abstraction, so a campaign can target one or both with the same audience, schedule and reporting. WhatsApp templates and Telegram’s open-message model are both handled correctly.

Yes. WhatsApp template approval is enforced before send, per-tier rate limits are respected, opt-outs are honoured, and Telegram bots respect spam-detection thresholds. Compliance is audited per tenant and surfaced in the admin dashboard.

Yes. Multi-tenant white-label deployments are explicitly supported. You set the pricing tiers, branding, login pages and billing; SpaGreen builds the customisation and trains your team on operations.

White-label SaleBot deployments start at $6,500 USD. Custom multi-tenant marketing SaaS with your own pricing, advanced analytics and reseller dashboards starts at $18,000 USD. Each project gets a fixed-price quote in 24 hours.
