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.

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.
One place for the messages you send every month, and the ones you send once a year.
Write the message once. Each parent gets it with their own name, the fee amount and the due date filled in.

Messages go out with natural gaps, inside daily limits that grow as your number builds trust. A new number starts at 50 a day.
Set the fee reminder for the 1st and 5th of every month, once. It sends on its own.

Describe the notice. Sendrex drafts it in English, Hindi, Gujarati or Hinglish, in your tone.

Common questions about fees and timings get an instant reply. Everything else waits for you.

Every campaign shows how many were delivered, read and replied to, and exactly who it did not reach.

Enter the code Sendrex shows you in WhatsApp's Linked devices. Your number, your name, your chats.
Pick from your phone's contacts or a sheet. Tag them as Parent, Student or Class 10 to reuse later.
Check the preview, then send. Sendrex paces the messages and tells you when it is done.
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.
Start free. Move up when you need more messages or more numbers.
