Nothing goes out without your approval

SMS

Text messages that respect people's choices

Send SMS from campaigns and journeys alongside email, WhatsApp and RCS. Messages go through your own provider account, and opt-outs are honoured everywhere.

How it works

  1. 1

    Connect your provider

    Twilio or Gupshup, with your own sender number or sender ID.

  2. 2

    Write the message

    Add merge tags like the first name, and see how many parts it uses and what it will cost.

  3. 3

    Approve and send

    The campaign goes out after approval, at each person's best hour if you choose.

What you get

STOP and HELP handled

An opt-out line is added for you, STOP is honoured at once, and HELP gets your answer.

Cost before you send

An estimate from your own rates per message part, before the campaign goes out.

Best time to send

Messages can wait for the hour each person usually reads and replies.

Templates to start from

Ready-made workflows that ask a few questions and do the rest. You can also just ask in your own words.

Questions

Whose account sends the messages?

Yours. SMS goes through your own Twilio or Gupshup account, so the provider bills you directly.

What happens when someone replies STOP?

They're unsubscribed from SMS straight away, and no campaign or journey texts them again unless they opt back in.

Try it with your own business

Connect your accounts, ask for what you need, and approve it before anything goes out.

Invite-only beta. We're letting people in gradually.
