WhatsApp first response time: how to measure it and bring it down

Why time to first reply is the indicator that weighs most in a WhatsApp sale, how to measure it properly and which changes reduce it without adding staff.

In a nutshell

People who write on WhatsApp often contact several businesses at once. The first one to reply with something useful has the edge. Measuring how long that first reply takes, by person and by time of day, shows where you're losing customers.

What exactly it measures

It's the time between the customer's first message and the business's first reply. It's worth measuring human replies and automated ones separately, because an instant automatic greeting doesn't answer the question.

Look at the average, but also at the extremes: ten customers who waited hours matter more than the average.

  • Customer's first message.
  • First useful reply.
  • People and automation measured separately.
  • Average and extreme cases.

Where the time gets lost

There's almost always a pattern: inquiries that arrive after hours, lunchtime peaks, a shift with fewer people or conversations nobody picked up because they had no owner.

Breaking the indicator down by time slot and by person shows which of those patterns is yours.

  • After hours.
  • Demand peaks.
  • Understaffed shifts.
  • Conversations without an owner.

How to bring it down without adding staff

Automatic assignment keeps a conversation from waiting for someone to pick it up. Phone notifications let people reply even when they're away from the computer.

An AI assistant can instantly answer frequent questions with your business information and hand off what needs human judgment, with the context already summarized.

  • Automatic assignment by department.
  • Push notifications.
  • After-hours replies that say when you'll respond.
  • AI for frequent questions.

Measuring it in Volga

Volga's reports show time to first reply for the team and for each agent, calculated from the messages in the period you choose. With the iOS and Android app, each person gets a notification when a conversation is assigned to them.

If the business uses the AI assistant, repeated questions are answered automatically and the team focuses on the ones that need a person.

  • Time to first reply by agent.
  • Filter by period.
  • Mobile app with notifications.
  • AI assistant with handoff.

Frequently asked questions

Questions about this guide

What's a good first response time on WhatsApp?

It depends on the industry, but for sales inquiries the edge is won in minutes. Rather than setting a universal number, measure your own and bring it down week by week in the time slots where it's slowest.

Does an automatic greeting count as a reply?

Better not to count it. An automatic greeting confirms the message arrived, but the customer is still waiting for an answer to their question.
