SMS marketing, Australia

SMS marketing that sits right next to your email.

Send16 puts text messages and email in the same place. Send an SMS campaign to a segment, or drop a text into an automation after an email that didn't get opened. Opt-outs, quiet hours and consent are handled for you.

Free for 5,000 emails a month. No card needed.

Why Send16

Made for how Australian businesses actually send.

One customer record for email and SMS

Phone numbers, SMS consent and email consent live on the same contact, so you never text someone who only agreed to email.

STOP and HELP handled automatically

Replies like STOP, UNSUBSCRIBE or END turn off SMS for that contact straight away. HELP gets an automatic reply.

Quiet hours

Set the hours you never want texts going out, and scheduled SMS campaigns wait until the window opens.

Your own number, your own rates

SMS sends through your own Twilio account, so you keep your sender number and pay carrier rates directly with no markup from us.

Questions

Common questions.

Which plan includes SMS?
SMS campaigns and SMS automation steps are part of the Growth plan. Email features start on the free plan.
How much does each text cost?
Texts go through your own Twilio account, so you pay Twilio's carrier rates directly. Send16 doesn't add a per-message markup.
Does Send16 handle opt-outs for SMS?
Yes. STOP, UNSUBSCRIBE, CANCEL, END and QUIT replies turn off SMS for that contact immediately, and START re-subscribes them.
Can I use SMS in abandoned cart and welcome flows?
Yes. Any automation can include an SMS step. Contacts without a phone number or without SMS consent are skipped and carry on through the rest of the flow.
