Message every parent on WhatsApp. In minutes.

Sendrex sends fee reminders, notices and admission offers from your own WhatsApp number, each one addressed by name.

Free to start. 1,000 messages a month on the free plan.

Built for the way a tuition class talks to parents.

One place for the messages you send every month, and the ones you send once a year.

Personal, to hundreds at once

Write the message once. Each parent gets it with their own name, the fee amount and the due date filled in.

Writing a campaign in Sendrex

Sends at a safe pace

Messages go out with natural gaps, inside daily limits that grow as your number builds trust. A new number starts at 50 a day.

Reminders that repeat themselves

Set the fee reminder for the 1st and 5th of every month, once. It sends on its own.

Three steps to your first message.

  1. 1

    Link your WhatsApp

    Enter the code Sendrex shows you in WhatsApp's Linked devices. Your number, your name, your chats.

  2. 2

    Choose who gets it

    Pick from your phone's contacts or a sheet. Tag them as Parent, Student or Class 10 to reuse later.

  3. 3

    Send now or schedule

    Check the preview, then send. Sendrex paces the messages and tells you when it is done.

Your contacts are yours.

Your contacts are kept on your phone, not on our servers. A number is sent to us only to deliver a message, and removed once it is sent. Anyone who replies STOP is skipped from then on. You can delete your account and everything in it from the app, at any time.

  • Contacts stay on your phone
  • STOP is always respected
  • Delete everything in two taps

Questions.

Is Sendrex an official WhatsApp product?

No. Sendrex links to your WhatsApp the same way WhatsApp Web does, using a library that WhatsApp does not provide or support. Sendrex is not affiliated with WhatsApp or Meta.

Can my number get restricted?

It can, if WhatsApp sees your messages as spam. Message only people who know your tuition class, keep the default limits, and let people opt out. Sendrex paces sending to lower the risk, but it cannot remove it.

Does my phone need to stay on?

No. Once your number is linked, campaigns and scheduled reminders send from our servers, even with your phone off.

I do not want to link my number. Can I still use it?

Yes. Choose "My WhatsApp app" when sending. Sendrex opens each chat with the message ready and you tap Send yourself.

Which languages does it write in?

English, Hindi, Gujarati and Hinglish. The app itself is available in English, Hindi and Gujarati.

Can I cancel?

Yes, at any time. You keep your plan until the end of the period you paid for, then move to the free plan. Nothing is deleted.
