01
Shared Team Inbox
Assign conversations to agents or teams, resolve and reopen them, and keep internal notes. Canned replies, macros, labels, SLA policies by priority and CSAT surveys come with it.
What You Get
02
Bulk Campaigns
Build audiences from pasted numbers, groups, tags or saved segments. Duplicates and opted-out contacts are removed, and you can schedule, repeat on a cron rule, set send windows and watch progress live.
03
A/B Tests And Link Tracking
Test message variants on a sample group and let Zender pick the winner automatically. Links become short tracked links per recipient, with clicks counted, bot clicks filtered and an optional custom link domain.
04
Chatbot Flow Builder
Build flows on a visual editor with triggers such as inbound messages, schedules, webhooks, form submissions and link clicks. Add conditions, delays, waits for a reply and HTTP requests, then review every run step by step.
05
Drips, Forms And Reviews
Enroll contacts in multi-step sequences, collect subscribers with public subscribe forms that confirm opt-in, and send review requests with review links.
06
16 SMS Providers
Connect Twilio, Telnyx, ClickSend, Routee, Vonage, Plivo, Infobip, Bird, Sinch, SignalWire, Bandwidth, Clickatell, TextMagic, Africa's Talking or MSG91. A Custom HTTP driver connects compatible public HTTP SMS APIs using GET, POST or PUT with JSON or form fields.
07
WhatsApp Business API
Create, sync and send templates, browse a template library, send reply buttons, lists, media and reactions, and run campaigns. Click-to-WhatsApp ad attribution shows which ad started each chat.
08
Verify API For OTP
Create, check, resend and cancel verifications over the channels you have installed, with fallback channels and fraud protection. Inbound verification lets a user reply to confirm.
09
REST API And Webhooks
Send messages and manage contacts with token auth and named abilities. Outgoing webhooks include a delivery log and secret rotation, idempotent requests are supported and an OpenAPI contract is published.
10
Plans, Credits And Payments
Build plans with feature switches, wallet credits, credit packs and vouchers, with PDF invoices and usage alerts. Bank Transfer and PayPal are included, and more gateways are paid plugins.
11
Roles, Branding And Domains
Workspaces get admin, manager, supervisor and agent roles, plus custom roles when the plan allows. Messenger can run on a custom domain, and plans can switch on workspace branding.
12
AI Assist In Messenger
Agents get suggested replies, conversation summaries, draft rewrites and message translation. Connect your own provider key from Anthropic, OpenAI, Grok, DeepSeek or OpenRouter.
13
Partner Network
Workspaces can share Android SIM or Phone Bridge lines with per-unit and per-country rates. Partners request payouts and follow balances, and an optional referral program pays commission.
14
Languages And RTL
The interface ships in English, Arabic and Japanese. Arabic is set up right to left, and admins can manage languages and translation overrides.

Frequently Asked Questions
What is Zender?
Zender is a self-hosted messaging platform. Customers send campaigns, build chatbot flows and answer conversations from a shared inbox, and you run it as a service with your own plans, credits and payment options.
Is there a live demo of Zender?
Yes. Zender has a live demo at https://zender.titansys.dev where you can try the dashboard before buying.
Which channels are included?
The WhatsApp Business API (WABA) and SMS providers are built in. Every other channel is an optional plugin that you upload in Admin > Plugins, so you only install what you need.
Which SMS providers does it support?
Sixteen drivers are built in: Twilio, Telnyx, ClickSend, Routee, Vonage, Plivo, Infobip, Bird, Sinch, SignalWire, Bandwidth, Clickatell, TextMagic, Africa's Talking, MSG91 and Custom HTTP. SMPP is available as a free plugin.
Which plugins are free and which are paid?
Android Gateway, WhatsApp (unofficial), Email, SMPP and WhatsApp Embedded Signup are free for verified buyers. Every other plugin is sold separately, including Telegram, Website Chat, Web Push, Phone Bridge, GSM Modems and the payment gateway and integration plugins.
Can I send SMS from my own Android phones?
Yes, with the free Android Gateway plugin. Pair a phone by scanning a QR code, use multiple SIMs with per-SIM limits and destination prefix routes, and run USSD codes from the dashboard.
Can I upgrade from an earlier Zender version?
No. Zender 5 is a new product with no upgrade path from earlier Zender versions, so you install it fresh.
What is the difference between the Regular and Extended license?
Both licenses include Zender 5. The Extended license also gives reduced prices on most paid plugins and free access to the WordPress, WHMCS and Perfex plugins. MCP, RCS and other extras are not discounted.
How do I get Zender after buying?
After buying, sign in at https://dashboard.titansys.dev with the Envato login button to download it and get support.
