Auto WhatsApp after call in brief

Auto WhatsApp after call is the core job of WappBlaster's Android app, a post-call follow-up tool priced at ₹2499 ($22.99) per user per year after a 3-day trial. Running in the background, the app notices when an incoming, outgoing or missed call ends, picks the template saved for that call type, and sends it through the phone's own WhatsApp account within seconds. Setup takes about 5 minutes: install from Google Play, grant phone and accessibility permissions, write the three templates, set a cooldown and switch the app on. The cooldown keeps the habit polite, and 7 days is the suggested gap before the same number hears from you again. A good template stays under 100 words, names the sender and business, and links the free lifetime catalogue website that comes with the app. An offline queue holds messages while the phone is locked or out of signal, and analytics count how many went out.

What is auto WhatsApp after call?

Auto WhatsApp after call is phone automation that sends a prepared WhatsApp message to the other person as soon as an incoming, outgoing or missed call ends.

WappBlaster's Android app does this for ₹2499 ($22.99) per user each year, and a 3-day trial comes first.

  • Every caller gets a follow-up even when you are busy or on the road.
  • Separate messages can be set for incoming, outgoing and missed calls.

Auto WhatsApp after call benefits

  • Follow-up on every call

    Callers receive your details even when you are driving or between meetings.

  • Missed callers kept warm

    Someone you could not answer gets a message instead of silence, while their interest is still fresh.

  • Contact details in the chat

    Your name, business and number sit in the message, so the caller can save or forward them later.

  • Catalogue in front of every caller

    The included catalogue website link lets people browse products right after the conversation.

  • No manual copy-paste

    Nobody on the team types numbers into WhatsApp by hand after each call.

  • No repeat messages

    A 7-day cooldown stops regular callers getting the same note every single time.

When auto WhatsApp after call is the wrong choice

  • If you want to reach people who have not called you or been called from this phone, post-call follow-up does not cover them.
  • Teams that take calls on an iPhone or a desk landline need another setup, since the app detects calls on an Android phone.
  • For large promotional broadcasts, use an official WhatsApp Business API tool instead; after-call messages are one-to-one, not bulk sending.
