White-Label Excel SMS Plugin for Resellers

Let your clients send bulk SMS straight from Excel, under your own brand

Illustration about Excel SMS Plugin
White-Label Add-In

A Ready-Built Excel Plugin, Branded to You

Plenty of your clients already run their contact lists and campaigns out of Excel. Instead of asking them to learn a new panel or building a spreadsheet integration yourself, license the Excel SMS plugin and point it at your own branded API endpoint. Your clients install it, see your brand in the ribbon, and send bulk SMS straight from the spreadsheet they already use, on top of the traffic they're already sending through you.

What the Ribbon Actually Does

Ribbon Function What It Does
Send SMS Send a single message directly from the spreadsheet.
Group SMS Send a bulk campaign straight from a column of numbers and messages.
Sent Report Track delivery status for messages already sent.
Check Balance See remaining account credit without leaving Excel.
Settings / Admin Manage login credentials and configuration.

Built for Reseller Distribution

Your Brand, Not Ours

  • Point the add-in at your own branded API endpoint before you distribute it.
  • Your clients connect through your platform, using your credentials, your branding.

Ready-Built, Not a Dev Project

  • A finished Excel-DNA (.xll) application, not a spec you have to build from scratch.
  • License it and start distributing, instead of scoping your own integration.

Credentials Handled Securely

  • Login credentials encrypted with Windows DPAPI under each user's own profile, not stored as plain text.
  • API traffic runs over HTTPS with TLS 1.2 or higher.

Straightforward for Your Clients

  • Runs on Windows 10 or 11, Excel 2013+ or Microsoft 365 (64-bit).
  • One-time install with administrator rights, then it's just a ribbon tab in Excel.

FAQ

Frequently Asked Questions

Yes. The add-in can be pointed at your own branded API endpoint, so when your downstream clients install it and send SMS, they're connecting through your platform, not ours. Your name is what they see.

A native SMSGatewayCenter-style ribbon tab with five functions: Send SMS for individual messages, Group SMS for bulk campaigns straight from a spreadsheet column, Sent Report for delivery tracking, Check Balance for credit visibility, and Settings/Admin for configuration.

Windows 10 or 11, Excel 2013 or later (or Microsoft 365, 64-bit only), and .NET Framework 4.8. Installation needs administrator rights, a one-time step when first setting it up.

Credentials are encrypted using Windows DPAPI under the installing user's own profile, not stored as plain text, and the add-in connects to the API over HTTPS with TLS 1.2 or higher.

No. The add-in is a ready-built Excel-DNA (.xll) application. You license it, point it at your branded endpoint, and distribute it to your clients, instead of scoping and building a spreadsheet integration from scratch.

Payment reminders, promotional campaigns, OTP distribution, and any bulk send built from a contact list they already manage in Excel, without needing a separate desktop tool or asking a developer to write an integration.
