Auto-Reply

Every conversation followed up — automatically.

Auto-Reply sends an instant, on-brand message the moment something happens — a call ends, a customer writes first, or a keyword lands — on WhatsApp and SMS alike. No code, live in minutes, working around the clock.

What it is

A reply ready before you are.

Auto-Reply listens for the moments that matter — a finished call, a first message, a keyword, the end of business hours — and answers instantly in your brand’s voice. The same rule can follow up on WhatsApp and SMS at once, so customers always hear back and your team never starts from zero.

01

Always on

Replies fire 24/7 — nights, weekends and holidays included — so no moment is missed.

02

Two channels

Follow up on WhatsApp and SMS from one rule, each formatted for its channel.

03

No code

Build rules from simple triggers in minutes. No developers, no flowcharts.

Live in four simple steps.

1

Link your WhatsApp number and SMS Sender ID to Mersal in a few clicks.

2

Pick a trigger

Choose what starts a reply: a finished call, a first message, business hours, or a keyword.

3

Write the message

Compose on-brand replies with merge fields, links and quick-reply buttons.

4
