ERPNext ships a basic Newsletter DocType and Email Campaign scaffolding, but marketing teams hit a wall fast: no visual builder, no true drip sequencing off customer behavior, no per-recipient open and click analytics, and segmentation that means hand-writing filters or maintaining Email Group lists by CSV. The result is that most teams bolt on Mailchimp, Brevo, or HubSpot — and immediately lose the single source of truth. Contact consent, unsubscribe state, and engagement history now live outside tabContact and tabLead, sync jobs drift, and your sales team can no longer see in ERPNext who opened what. That disconnect is exactly where native ERPNext runs out of road.

ECOSIRE builds Email Marketing Automation as a proper Frappe app (its own module, installed via bench get-app and bench install-app) so the entire lifecycle lives inside ERPNext. We add first-class DocTypes — Campaign, Email Template, Automation Flow, Flow Step, and Email Event — plus a visual, drag-and-drop email builder backed by a reusable template library. Behavioral automation is driven by hooks.py doc events (for example, on_update of a Lead crossing a status, or after_insert of a Sales Order) and by scheduler_events that advance time-delayed drip steps through the Frappe background queue, so a sequence can fire "3 days after signup" or "when deal stage changes" without external cron. Every send is enqueued through Frappe's email queue against your configured Email Account / SMTP.

Tracking is engineered, not guessed. We embed a per-recipient tracking pixel and rewrite links through a whitelisted redirect endpoint, so opens, clicks, and bounces are captured as Email Event records and rolled up onto the Campaign and back onto the originating Contact/Lead — visible in the ERPNext form and queryable via report. Segmentation is built directly on ERPNext data: saved segments compile to Frappe query filters across Contact, Lead, Customer, and any linked DocType, so "customers in UAE with an open opportunity and no order in 90 days" is a live, self-refreshing audience rather than a stale list. A/B subject-line testing splits the audience, measures open rate on the winning variant, and can auto-promote the winner. All of it respects Frappe permissions and role profiles — a Marketing Manager role sees campaigns; a Sales User sees engagement on their own leads — and exposes whitelisted REST methods so your website or app can trigger flows programmatically.

Because this is build-to-order, nothing ships as a blind download. We start with a short scoping call to confirm your ERPNext version (v15 or v16), your sending infrastructure, consent/unsubscribe requirements, and the exact triggers and segments you need. We then build against your requirements, validate on a staging bench, run UAT with your team, and install into production with a documented rollback. Typical delivery is 2–4 weeks from confirmed scope, and you receive the full source and git repository so the app is yours to keep and extend.
